At what temperature are cucumbers grown in a greenhouse

Growing cucumbers and tomatoes on a personal plot is quite a lucrative business. Some gardeners work for profit, others for the soul and pleasure. However, getting a bountiful harvest of vegetables depends on growing conditions and proper care. A greenhouse is an ideal construction and a gardener's assistant. With insufficient warmth and a short summer period, it will help keep the desired temperature.

But here, too, the basic rules must be observed to create a favorable climate. Some vegetables, in particular cucumbers, cannot tolerate sudden temperature changes. Because of this, plants get sick, stunted and bear little fruit.

It is not enough for gardeners to know the optimal temperature for cucumbers in a greenhouse.. You need to be able to regulate it, despite different weather conditions.

Greenhouse preparation

Preparation begins immediately after harvest. If a new greenhouse is installed, the soil must be prepared in the fall.

The land is enriched with rotted manure and peat in equal proportions. The percentage of soil acidity is monitored, which is no more than pH 7.1.

The size of the greenhouse should be chosen correctly. Do not set views that are too long. It will be difficult to achieve good ventilation in them. Also, in cold weather, it will be more difficult to increase the temperature in the cucumber greenhouse.

Growing cucumbers in a greenhouse

Planting cucumbers is carried out:

• seeds;
• seedling method.

The second method will allow you to get the harvest earlier, on average, two weeks.

Cucumbers - the culture is quite tender and does not tolerate transplantation. The roots of the plant are located shallow in the soil. Therefore, seeds for seedlings are planted in peat pots.

The main temperature indicators for greenhouse cucumbers:

Growth period of cucumbers	Temperature
Sowing seeds	25-28 ° C
Planting seedlings in the ground	20-23 ° C
Flowering period	25-28 ° C
When forming ovaries	20-35 ° C
For abundant fruiting	25-30 ° C

After the appearance of 4 leaves, the seedlings are planted in a permanent place. The soil temperature by this time should be at least 18 degrees. Otherwise, the plant will not develop and grow. With prolonged low soil temperatures, the seedlings will wither and die.

The optimum temperature for planting cucumbers

When cucumber shoots appear in the greenhouse, the temperature should be between 25 and 28 degrees. After the seeds have sprouted, 20-23 degrees is enough. Excessive heat will lead to excessive stretching of the sprouts. But good lighting for seedlings is a must.

The night mode of temperature in the greenhouse for cucumbers at the initial stage is set at 16-18 degrees. After a week, the night temperature is increased by an average of 3 degrees.

Greenhouse air temperature

What temperature should be in a greenhouse for cucumbers, depends on the stages of cultural development. For adaptation, the temperature is required lower than during the growing and fruiting periods.

Beginners should remember:

• lash growth slows down at 15 degrees;
• at 10 ° C, growth stops;
• temperatures below 9 degrees will kill the plant.

It is necessary to create an optimal microclimate at all stages of growth, regardless of external factors. This approach will ensure the rapid growth of young shoots and abundant fruiting in the future.

For this, the following rules are observed:

• in sunny weather, the temperature should be the maximum allowable;
• night readings depend on the previous day;
• at high temperatures, increased humidity is required, at low temperatures, accordingly, it decreases.

What is the optimal temperature in the greenhouse for cucumbers can be seen from the table.

Growth periods	Day		Night
	Sunny	Mainly cloudy
Before fruiting	23—25		18—20
Fruiting of the central stem	21—25		19—21
Fruiting lateral shoots	20—23		17—19

For abundant fruiting, it is very important to maintain the temperature at night. The intensity of fruit growth directly depends on this. Ideally, 21-23 degrees are set at night. Under these conditions, cucumbers bear fruit at full capacity. The duration of this process can lead to weakening of the lashes. Therefore, you need to give the plant time to recover. To do this, it is enough to lower the temperature to 18 degrees at night for a period of two weeks.

To avoid negative consequences, many gardeners install a temperature sensor in the greenhouse. With it, you can monitor the climate as needed and control unwanted temperature fluctuations.

Soil temperature in the greenhouse

Soil is the backbone of your gardening success. Before planting, it should warm up evenly. The temperature in the greenhouse for cucumbers should hold at around 25-28 degrees for a week.

There are various ways to heat the soil:

• the use of organic fertilizers;
• heating using additional covering material;
• the use of various types of technical heaters;
• water heating around the perimeter.

Air humidity in the greenhouse

Humidity, as well as temperature, is a rather important factor for the growth of cucumbers. Moisture readings should change each time they grow.

Seedlings require the lowest moisture content, which ranges from 70-75%. During the period of active growth of cucumber lashes, the required humidity is on average 90%. During the flowering period, it is reduced by 10-15%.

With a lack of moisture, the following processes may appear:

• plant growth is declining;
• the risk for the spread of pests and diseases increases;
• the upper part of the soil dries up;
• ovaries die.

It is not difficult to create humidity in a greenhouse. It is necessary to regularly water the plants and soil, monitor the temperature in the greenhouse. Humidity is very important for cucumbers, as they are 97% water.

Experienced gardeners recommend an evening watering of cucumbers in the greenhouse. In hot weather, morning or afternoon hydration is added.Whatever the temperature in the external environment, watering should be carried out regularly and abundantly.

If you ignore the basic conditions for caring for cucumbers in a greenhouse, then a high risk of developing various diseases is created.

The main consequences of non-compliance with temperature and humidity standards:

• the elasticity of stems and foliage is lost;
• the plant turns yellow;
• various spots appear on the sheets;
• peduncles fall or are missing;
• the flowers and fruits of the cucumber are drying.

Having found the above signs in the greenhouse, you need to immediately try to correct the situation. The cucumber is quite capricious and dies quickly.

Mixed landings

The greenhouse can be used quite rationally by using mixed plantings.

It should be borne in mind that this is quite difficult. The humidity and temperature in the greenhouse for cucumbers and tomatoes should be different. Tomatoes cannot tolerate the moisture that cucumbers need, and vice versa.

Ideally, you need to have two greenhouses:

• wet and stuffy for cucumber plantings;
• hot and well ventilated for tomatoes.

Despite the difficulties, many gardeners practice mixed planting, trying in various ways to achieve a good harvest. With some experience, good results can be achieved.

Basic recommendations for greenhouse cultivation of cucumbers

When growing cucumbers in a greenhouse, you need to remember that temperature is the main indicator of the amount of the crop.

It must be remembered that:

• planting is best done after the required temperature has held at the same level for at least 5 days in the greenhouse;
• the soil should not be allowed to dry out;
• watering with backward water under the root;
• avoid sudden temperature fluctuations in the greenhouse for cucumbers and tomatoes;
• drafts should not be allowed in the greenhouse with cucumbers;
• timely release the whips from the fruit.

Periodically, it is useful to arrange a greenhouse bath. It is necessary to water the greenhouse soundly and close all the vents and doors. In the case of a mixed planting, the procedure is not worth doing.

Cucumber is a rather capricious culture. You need to create the right balance of moisture, warmth and care. Don't forget about disease prevention. Apply organic and mineral fertilizers in a timely manner. Subject to all the rules and subtleties, the greenhouse will become an irreplaceable assistant in gardening.

When growing cucumbers in greenhouse conditions, it must be remembered that the temperature of the soil and air has a great influence on the formation of fruits and the yield of the plant. Therefore, it is necessary to clarify not only the maximum temperature limit for this type of vegetable crop, but also to know the methods of its regulation. You can read the guide on how to feed cucumbers in a greenhouse here.

The photo shows an example of maintaining the optimal temperature in the greenhouse.

The temperature regime in greenhouse conditions is one of the most important factors that affects such processes as the development and growth of shrubs, the amount of nutrients consumed, as well as their quality. Also, the temperature can affect the appearance of diseases and other important points. Read the instructions on how to tie cucumbers in a greenhouse

It turns out that every vegetable grower should be aware of the importance of observing the temperature regime for the type of crop that he grows in greenhouse conditions. And even more so, he should inquire about the ways and methods of lowering and raising the temperature, if it is really necessary.

What temperature can cucumbers withstand in a greenhouse?

In the event that the summer resident intends to grow cucumbers in greenhouse conditions, it is necessary to pay special attention to the temperature indicator of the inner atmosphere of the greenhouse.

So, according to experienced vegetable growers, before the first shoots appear in the containers for germination, they must be kept for a couple of days at a temperature of 25-28 0 C. After the first green petals appear, the film should be removed.The container with seedlings is moved to a well-lit place and the temperature is set at 20-22 0 С.

If we take into account the level of the night temperature, then in the first five days the seedlings should be grown at a temperature of 16-17 0 C. This is necessary to prevent the growth of the stem structure and the elongation of the seedling itself. After five days, the temperature is increased by 2-4 0 C. Instructions on how to pinch cucumbers in the greenhouse are here:

Attention! In no case should you allow sudden temperature changes, regardless of the time of day, you should reduce or increase the temperature gradually. It is best to do this in 3-4 steps.

In addition, with a sharp decrease in the temperature index, plants grown in greenhouse conditions can become seriously ill, lose crops, or simply die.

In the event that we are talking about keeping cucumber seedlings in greenhouse conditions, then the temperature should be set at around 22-24 0 C. This temperature indicator will be optimal for this type of cultivated plant.

Temperature regime

So why is it necessary to regulate the temperature in the greenhouse? Everything is quite simple, because each plant has its own "comfort zone", which includes the optimum temperature, air humidity and soil Hp. For this reason, the optimal temperature in the greenhouse room should be set, while all night and day temperature drops should be taken into account, and all external changes in the environment should also be emphasized. Read the instructions on how to prepare the soil for cucumbers in the greenhouse.

As an example, consider the following situation: various vegetable crops are grown in an open space. In one field, the grower receives huge amounts of harvest, while in the other he suffers only losses. The main problem is that the temperature indicator for all crops grown is the same in the daytime and at night. But, the "gardener" did not take into account that one plant vitally needs a temperature of 23-26 0 C, and the other will begin to bear fruit only at a lower temperature. As a result, a high yield is obtained in the first field, and absolutely nothing in the second.

The figure shows a table of temperature conditions for growing cucumbers in a greenhouse

Therefore, it is necessary to regulate the temperature indicator in the greenhouse for each type of cultivated plant, only in this way it can exceed all expectations. In the event that the temperature level fluctuates significantly, then there will be no sense from such a "shelter", because with a rapid decrease in temperature, the shrub will begin to poorly assimilate nutrients, and with a rapid decrease, the plant will simply burn out and stop growing.

Controlling the temperature index in a greenhouse will give an excellent opportunity for the plant to qualitatively develop its root system, gain growth and form fruits.

So, at what temperature is it desirable to plant cucumbers in a greenhouse? According to experienced vegetable growers, this indicator varies in the range from 20 0 C to 22 0 C. This temperature regime is also suitable for further growing the plant in greenhouse conditions.

This indicator can be called optimal for greenhouse cultivation, but the minimum temperature for cucumbers is 16 0 С and this is only at night.

As for the temperature of the ground in the greenhouse for cucumbers, it should not exceed 18 0 C and fall below 160 0 C.

But to grow cucumbers in a greenhouse should be with a gradual decrease and increase in temperature, and in spring and summer these indicators can differ significantly, because environmental conditions can have a significant impact on the life of the plant.

At what temperature do they die?

Often, novice vegetable growers ask themselves about the temperature regimes for growing plants in greenhouse conditions. Moreover, most of them are interested in the temperature at which a shrub can die, stop bearing fruit or lose all inflorescences.

Initially, every inexperienced summer resident should remember that when planting seedlings in the soil of the greenhouse, the same temperature conditions must be observed as when germinating. If they differ by at least 3-4 0 C, then the seedlings will not be able to adapt and will not be accepted. Read on for a review of greenhouse tomato varieties.

Then it is necessary to take into account the fact that at a temperature threshold of 29-30 0 C, the plant will die in 100% of cases.

You also need to pay attention to the temperature of the soil, it should not drop to 13 0 С, otherwise the root system will not be able to develop, which again will lead to the death of the plant.

So, now the conclusion should be drawn. Before starting to grow cucumbers, you need to carefully weigh everything and determine whether the "budget of the whole company" will be able to cover the costs of greenhouse equipment and the corresponding agricultural work required for this type of cultivated plants. Then you should determine how desirable the achievement of the goal is. And only after that, you can start doing what you love. The main thing is that if your own experience is not enough, then you can always ask your neighbor in the country or go to the site of the relevant topic.

The temperature for cucumbers in the greenhouse is an important factor that affects the full growth and development of vegetable crops and the yield of vegetables. An incorrectly selected temperature regime leads to plant diseases and slows down their vital processes. Experienced summer residents not only know at what temperature cucumbers grow efficiently in a greenhouse, but also understand how to normalize the microclimate in a greenhouse.

Cucumber greenhouse temperature

Optimal microclimate

A properly created microclimate for cucumbers in a greenhouse is a guarantee of a future harvest. The temperature regime creates a comfort zone for the vegetable crop along with the humidity of the air and soil and the acidity of the soil layer, maintaining these factors in an optimal ratio. When choosing the optimal temperature, the differences in the indicators on the thermometer in the daytime and in the evening are taken into account.

A sharp drop in the temperature regime adversely affects the state of vegetable crops, including cucumbers and tomatoes, therefore, the heat indicators need to be changed smoothly in the daytime and in the evening.

Gardener Tips

Experienced gardeners are advised to adhere to average temperature conditions of 20 ° C-22 ° C, at which cucumbers grow properly. It is this gradation, which allows you to create an optimal microclimate in the greenhouse when planting seedlings in the ground and further growing cucumbers in a greenhouse, is considered optimal. Those who are ready to spend some time adhering to strict rules and observing the thermal regime in the established norms should be aware of a number of standards:

• planting cucumber seedlings in open soil in a greenhouse assumes 20 ° C-22 ° C in the daytime and 16 ° C-18 ° C at night,
• during the flowering period, the thermometer on the thermometer in the greenhouse should be within 25 ° C-28 ° C,
• at the fruiting stage, the optimal heat regime is between 25 ° C-30 ° C in the daytime and 18 ° C-20 ° C at night.

With such indicators of air temperature, when planting seedlings and growing vegetables in a winter or summer greenhouse, the earth should be warmed up. The heat in the soil is maintained at 15 ° C-17 ° C.

Limiting indicators

When growing vegetables, it is enough to ensure that the thermal indicators of air and soil do not fall below and do not rise above the maximum permissible levels.

Growing seedlings

Daytime temperature

Initially, cucumber seedlings are able to grow well at daily rates of 25 ° С-28 ° С, but with the appearance of the first leaves, such a thermal regime begins to adversely affect plantings and requires a decrease to a level of 20 ° С-22 ° С.

With a sharp change in temperature, the bushes may die.

With a rapid decrease in degrees in the greenhouse, cucumbers cease to perceive the mineral elements necessary for them, and with a sharp increase in temperature, cucumber bushes begin to burn and, as a result, die.

Evening temperature

In the evening, cucumber bushes feel comfortable in the first week after planting with average values ​​of at least 17 ° C. This temperature index prevents excessive stem density and slows down unnecessary elongation of cucumber seedlings. However, after a week, such a degree begins to slow down them, and the plant needs to increase the level of heat in the evening hours to the prescribed 21 ° C-22 ° C.

Growing in a greenhouse

When growing a vegetable crop, the temperature in the greenhouse for cucumbers should not go beyond the limit norms:

• at 17 ° С-19 ° С and with an increase up to 35 ° С-40 ° С, ovaries on cucumber bushes are not formed,
• at 15 ° C and below, the growth and development of the cucumber plant begins to slow down and stop,
• when the thermometer scale is lowered to 10 ° C, the growth of cucumbers stops altogether,
• when the heat drops to a minimum of 8 ° C-9 ° C, the cucumber plant dies.

Sometimes, even when the temperature in the greenhouse for cucumbers differs from the required one by only 3 ° C, this turns into the inability of the cucumber seedlings to take root in the greenhouse. In the absence of automatic systems in the greenhouse that maintain the proper thermal regime, simple and effective measures are taken to change the microclimate.

Increasing the thermal regime

If, due to weather or other conditions in the greenhouse, the temperature has dropped and the created environment threatens the health of cucumber bushes, one of the techniques that experienced summer residents advise is used to quickly increase the thermal degree.

1. Create an air gap that can protect cucumber plants from the harmful effects of the environment. This can be done by covering the planting with a film for a short time.
2. It is possible to reduce heat loss and stabilize the microclimate in a greenhouse by creating a so-called second greenhouse, which is built directly on a vegetable planting in the form of a wire frame or made of wooden structures and other handy materials. In this case, a perforated film is used as a covering material, which ensures proper air exchange and creates ventilation for ventilation.
3. You can increase the thermal degree by mulching the soil. This is done both with organic matter and with a dark film.

Lowering degrees in a greenhouse

In some cases, excessively warm conditions are created in the greenhouse, which also have a detrimental effect on cucumbers, as well as a lack of heat. Together with high humidity, an increased degree leads to wilting of cucumber bushes and begins the process of developing infectious and bacterial diseases.

the temperature difference is just in the ground and insulated beds

Optimum temperature for seedlings

When the temperature regime in the greenhouse must be changed downward:

• the free flow of air into the greenhouse structure through the pediment is ensured; in such ventilation, the thermal degree can be reduced immediately by 7-12 points,
• a chalk solution is used, which is prepared from 2 kg of a mixture with a chalk component and a 10-liter water volume, a little milk is added to this liquid mixture, the structural elements of the greenhouse are sprayed with this working solution, after which a decrease in the thermal degree is immediately noted by several points.

The greenhouse is usually watered with a watering can. But if you have the opportunity to install sprinklers yourself, it is recommended to do so. The presented system is very popular with cucumbers, who like uniform and abundant watering. Nevertheless, watering is recommended during the day in sunny weather, while the vents will have to be closed.

The main condition for a good harvest of vegetables is the presence of fertile soil. Ideal for cucumbers will be a mixture of turf, peat and humus in the same ratio. Be sure to check the acidity of the soil. If it is higher than 6.5, it is better to dilute it with a lime material. Cucumbers don't like acidic soil. In addition, there are much more pests living and breeding in it. So that the vegetable is not affected by pests, ash is introduced into the soil. Fertilize the soil a few days before planting seeds, add urea, superphosphate, potash fertilizers.

Plants are recommended to be planted in a warm greenhouse in early April. And in film coatings without additional heating in the southern regions - about April 10. The direction of the rows is known to play an important role. So, if you plant from north to south, lighting for plants will be more accessible, compared to the east-west direction.

In case of violation of this rule and in the case when cloudy weather is delayed, the plants are strongly stretched in the zone of the hypocotal knee.

Planting: how to plant cucumbers in a greenhouse

It is not recommended to plant cucumbers in the same greenhouse with tomatoes, since the agricultural technology for growing these crops varies significantlySo, we will grow cucumbers in a greenhouse. To do this, we need, first of all, to put up a greenhouse. Now there is a large selection of them, choose and install the one you like. Previously, manure, peat, humus are scattered over the greenhouse territory, all this is dug up in the fall. Planting cucumbers in the greenhouse is carried out in late April or early May.

The productivity of a cucumber increases with an increase in the concentration of carbon dioxide in the air (up to a certain limit). The main source of carbon dioxide in small greenhouses is manure, which releases this gas when it decomposes in the soil. To increase the content of carbon dioxide in the air, they place a barrel or other container in the greenhouse, fill it halfway with fresh manure (for example, bird droppings), fill it up with water and let it ferment, stirring the contents of the barrel daily. During fermentation, the air in the greenhouse is enriched with carbon dioxide. The fermented slurry can then be used for fertilizing, diluting it with water in the recommended proportions.

Care for cucumbers in the greenhouse

For parthenocarpic hybrids, bee pollination can be harmful. If bee-pollinated and parthenocarpic hybrids are grown side by side, it is recommended to remove the corolla of female flowers from parthenocarpics before they bloom. A bee will not sit on a flower without petals, and an ovary will grow without a corolla. In hybrids with partial parthenocarp (April F1, Zozulya F1, the first female flowers must be manually pollinated.

2 g zinc sulfate;

The soil must be fertilized with organic compounds, they are applied immediately before digging up the soil. Nutrients are evenly distributed over the surface of the site, while per square meter for depleted soil, at least 10 kg of compost and 300-400 g of superphosphate are needed, and for fertile ones, the amount is halved. If it was not possible to enrich the soil with organic substances, this can be done in the spring, directly when transplanting seedlings directly into the holes or rows, at the rate of 3-5 kg ​​of humus per 1 m2.

... The best neighbors for cucumbers are zucchini.

Some people leave 2-3 cucumbers in the garden for ripening every year, so that they can then collect seeds for planting in subsequent years. But now you don't have to do that. There are a lot of seed varieties sold, already treated with the necessary means to improve growth - the choice is huge. It is easier to just buy the variety you like, the main thing is that it suits you according to its properties.

Fertilizing cucumbers in the greenhouse

At the beginning of fruiting, the crop is harvested 2 times a week, and with mass fruiting - every other day, or even every day, if possible. If harvesting is done rarely with overgrown greens, then this will lead to a significant decrease in the overall yield. At each collection, it is also necessary to remove all ugly and diseased ovaries. The crop, as a rule, is harvested in the morning, when it is not yet hot in the greenhouse, and the greens are well saturated with moisture.

The soil in a cucumber greenhouse should be constantly moist, but not waterlogged. Both lack and excess of moisture are harmful. At the same time, the ovaries fall off, the leaves die off, the fruits are deformed, and the yield decreases. Sudden fluctuations in soil moisture lead to root cracking and root rot. In hot weather, watering should be done every day, consuming 5-10 liters of water per 1 m2, and on cloudy days, watering is carried out only if absolutely necessary. To accelerate fruiting in greenhouse vegetable growing, a weak short-term drying of the soil is used at the beginning of fruiting. Before watering cucumbers in the greenhouse, you need to check the condition of the soil.

Greenhouse preparation begins in the fall. Post-harvest residues and the upper soil horizon by 4–5 cm are removed, since disease-causing elements accumulate in it. Wooden parts of greenhouses are disinfected with a strong solution of copper sulfate, and metal parts, if required, are painted.

How to do it? Reduce watering during flowering. And return the standard frequency of watering during the period when the flowers have already begun to fade.

Cucumbers in the greenhouse, cultivation.

There are several ways to plant cucumber cups. For example, wide-row, when it is necessary to plant the plants in rows with gaps of about 1 m, and between the holes - 30 cm.When belt planting, you can place plants in rows with a distance of about 80 cm, and in ordinary rows, a row spacing of 60-70 cm is used.

The first application is made one week after the first shoots, the second - two weeks after the first fertilization of the soil, but before the flowers appear. The content of minerals is indicated in the table (the amount of substances is taken for 10 liters of water):

500 g of soda.

You need to dig up to the depth of the bayonet of the shovel, carefully laying the layers and trying not to break the clods. Since in this case, the moisture of winter precipitation can easily seep into the lower layers of the soil, which will increase productivity.

The scheme for planting cucumbers in the greenhouse also significantly affects the expected result. Seedlings are planted in pre-prepared holes to a depth of about 14-16 cm. To create an optimal temperature regime for the soil, it is recommended to cover the bottom of the holes with sawdust or pine bark, and sprinkle the top with soil mixed with straw. The distance between the rows should be about 50-60 cm.Pour 1 liter of water into the formed furrows and carefully place the seedlings, while note that the distance between the future cucumber bushes should be 20-30 cm. This will provide the plants with sufficient area for growth and full development.

For planting seedlings in a greenhouse, we make beds 67-70 cm wide, it is more convenient to handle such. The height of the beds is up to 30 cm. Beforehand, you can water them with a weak solution of potassium permanganate for disinfection. Then we plant the seedlings in a row. To do this, we make holes or a furrow with a depth of 10-11 cm, we plant the plants after 30-31 cm. We cover it with earth and water each hole with water carefully so as not to erode the ground at the roots.

And if you plant cucumbers not only in the garden, but also in the greenhouse, and at the same time at different times, pick up fertilizer and find a productive variety? Then you will be the first to try the cucumbers, and you will still shoot in late autumn!

It is better to water in the evening, when the water warms up enough. In addition, it must be borne in mind that the fruit of the cucumber grows mainly at night. To make the soil less compacted during watering, and the roots are not exposed, a sprinkler must be put on the spout of the watering can or at the end of the hose.

Which varieties of cucumbers are best planted for the greenhouse, and which ones for open ground?

The soil in the greenhouse is dug up after organic, mineral fertilizers and lime have been applied. Before digging, at the rate of 1 m 2, it is scattered: 20-25 kg of unripe manure, 30-40 g of phosphoric and potash fertilizers and 200-500 g of lime (depending on the acidity level). Nitrogen fertilizers are not applied in the fall, they should only be applied in the spring.

It is also important to ensure good air exchange inside the greenhouse, so we recommend that you read the article "Making ventilation in the greenhouse yourself".

1. Cucumbers are planted with seeds or seedlings. Everyone decides for himself which method to grow cucumbers. But it is important to know that when planting seeds in a greenhouse, there will be many barren flowers on the plant. Planting seedlings takes longer. But you will get the harvest earlier. You can plant cucumbers in a polycarbonate greenhouse in any way.
2. When planting, the plant is placed in such a way that the cotyledon leaves are at surface level, covered with soil around it tightly and watered abundantly.
3. Top dressing

Planting cucumbers in open ground

In addition, you can soak seeds for nutrition in mineral solutions: 5 g of potassium nitrate, 0.2 g of magnesium sulfate and 10 g of superphosphate are needed per liter of water.

With a full rotation of the soil layer, the seeds of weeds and other flowers, falling into the depth of the soil, cannot germinate. And the larvae of caterpillars and other insects, finding themselves on the top, die in the frost or are destroyed by birds.

After planting, water the cucumbers abundantly and mulch the soil with sawdust or a peat-sand mixture to prevent cracking, ensure optimal temperature conditions, and uniform evaporation of moisture. In the future, it is recommended to water the cucumbers about 2 times a week and periodically spray the plants with water at room temperature. When the weather is calm, the greenhouse should be regularly ventilated to allow air circulation and additional hardening.

In early April, we process the purchased seeds for planting seedlings. We check them beforehand: pour a little salted water into a bowl and pour the seeds there, moisten them well. Seeds that fall down are suitable for planting. We briefly dip them in a pink solution of potassium permanganate for disinfection.

If you decide to grow cucumbers in a garden bed under a film or in the open air, then any early ripening varieties will do. And if you need seeds for planting in a greenhouse, then it is better to buy self-pollinated varieties or parthenocarpic ones.

The heavily compacted soil is pierced with a pitchfork. After each watering or feeding, the soil is loosened shallowly, since the roots are too close to the surface. When they begin to come out in the form of white threads, you need to add a fresh nutrient mixture. During the season, sprinkle it 2-3 times with a layer of 1.5 cm.

If soil preparation for some reason is postponed to spring, then in order to avoid the introduction of infectious substances, it is necessary to introduce manure before digging, but not everyone, but only the one that has undergone biothermal disinfection.

One of the best options will be the Hercules F1 hybrid

It is not recommended to keep seedlings in pots for more than 24 days. The best time to plant seeds for seedlings is mid-April (17-20), depending on where you live. For seedlings, the temperature is maintained at 22-24 degrees. When 4 real leaves appear, you can plant them in a greenhouse at an air temperature of 25 degrees.

Planting should be carried out in cloudy weather, and in sunny weather - in the afternoon.

Growing seedlings for an accelerated harvest

As the seedlings grow, add the soil to the pots - additional roots form on the hypocotal knee of the cucumbers, which will nourish the plant, prevent it from stretching and ensure good survival during transplantation.

Plants can be planted in various types of greenhouses, with the most common among them being a warm greenhouse and film structures.

Tying cucumbers is one of the keys to successful greenhouse cultivation. The wrong or untimely approach will lead to a decrease in the number of leaves, as well as to a decrease in yield indicators. What is the reason for this? Cucumbers are extremely light-loving plants, so their lashes are actively drawn to the sun and, as a result, become too long, bend and fall off, which has an extremely negative effect on the condition of the bush.

Summing up, highlighting the features (differences) of planting cucumbers in the greenhouse and in the open field

• Then we place the seeds in the refrigerator on the middle shelf for a couple of hours to harden. After that, we plant the seeds in prepared plastic cups or other jars filled with ready-made soil for cucumber seedlings (purchased in a store) or prepared by us from equal parts of fertile soil, humus and peat.
• Few people know the difference between parthenocarpic and self-pollinating cucumber varieties. In fact, everything is simple. Cucumbers can be bee-pollinated, self-pollinated and parthenocarpic:
• Due to the ability (property) of the film to not allow water vapor to pass through, in film greenhouses, optimal moisture conditions are created for the cucumber culture. But at the same time, air stagnation should not be allowed, in order to avoid the spread of diseases. For this purpose, it is necessary to carry out daily ventilation of the greenhouse. It is carried out carefully, only through the upper vents, avoiding drafts. On sunny days at noon, it is useful to do so-called "poultices", closing the greenhouse for 1.5-2 hours, after which it is ventilated. Drying of air in the greenhouse space should not be allowed, since in dry air favorable conditions are created for the reproduction of spider mites.
• In the spring, as soon as the weather permits, the greenhouse is covered with a film, and when the soil “ripens”, ridges 20-25 cm high are made. They are placed either along or across, depending on the size of the greenhouse. If it has a width of 2 m, then one row is planted to the left and right of the central track. With a greenhouse width of 4 m, there should be 2 paths and 4 rows of planting: one row on the sides and two rows on the central wide ridge. In a row, seedlings are planted every 30–35 cm, that is, 3–3.5 plants are placed per 1 m2 of greenhouses. With a denser planting, the illumination of the plants deteriorates significantly.

Do not miss such an important point as the formation of cucumbers with your own hands. So the length of the plant stem should be 0.5 - 3 meters.

Cucumbers are rarely planted so that they bear fruit well and do not get sick. Put rotted manure into a hole, 5 cm deep, mix with earth. Plant a seed, sprinkle lightly with earth, water abundantly, cover with foil.

Garter cucumbers in the greenhouse - learning techniques

What needs preparation?

The process of growing a plant comes down to creating and maintaining optimal temperature conditions. Cucumbers and tomatoes grow well in greenhouses at 25 ° C, exceeding more than 30 ° C is unacceptable, otherwise the ovaries may fall off and pollination of flowers will worsen. It is recommended to ventilate the greenhouse to avoid an undesirable temperature rise. It should be borne in mind that cucumbers do not like drafts and it is impossible to open the end entrances. In spring, the greenhouse is ventilated only during the day and closed until the sun sets in a few hours. In addition, you need to maintain the optimum humidity level - 90-95%.

Superphosphate

Sowing cucumbers can be carried out both directly into the ground in the greenhouse, and in special pots or cups without picking. In this case, it is allowed to plant tomatoes with cucumbers. For this, a mixture for planting is preliminarily prepared, which should be nutritious and coherent, but loose. To prepare the soil, you can use the following compositions:

It is important not to forget to make three cuts on each log for the staples that act as a fixator. In addition, overgrown cucumber tendrils cling to neighboring plants, creating barriers to their growth and forming additional shading. The correct formation of the bush will provide it with full lighting, will significantly increase the performance of the ovaries and will have a beneficial effect on the quantitative and qualitative characteristics of the future harvest. In addition, the fruits will be deprived of direct contact with the soil, and this will significantly reduce the likelihood of rotting vegetables and contribute to their uniform ripening. And it is much easier to take care of the plant, water it, spray it, protect it from various diseases and garden pests when it is tied up. We make a hole 2 cm deep and place 1-2 seeds there, bury them and water a little. These cups need to be put in a warm place, covered with a film on top, and after 3-4 days the first sprouts will appear from the ground. When the seedlings are 25-30 days old, they can be planted in a permanent place.

The varieties of cucumbers pollinated by bees have flowers for women and men. If there are more male ones on the stem, then there will be few ovaries. For this, the stems are pinched, which allows lateral shoots with female flowers to grow. The best bee-pollinated varieties are F1 Crane, Spring F1, Blues F1, Salting, Graceful and others.

Top dressing of cucumbers in the greenhouse is carried out to regulate the concentration and ratio of nutrients in the soil solution in accordance with the requirements of the plants. It is possible to determine exactly what a plant needs only by the results of agrochemical analyzes of soil and plants, which is practically inaccessible for individual gardeners. To some extent, however, the mineral nutrition of plants can be judged by their appearance. So, with an excess supply of nitrogen, the plants "fatten" - they grow violently, their leaves are intensely green, the upper leaves often curl, budding and flowering are delayed. This is also observed when too large doses of fresh manure are applied.

What is a garter for?

Wire trellises are stretched over the rows at a height of about 2 m, to which the plants are later tied with twine.

It has already been indicated that greenhouses should be equipped with trellises. It is also worth using a pinch. The bush forms when the eighth leaves appear. You should pinch flowers in the first three sinuses at the very beginning.This material will tell you about autumn work in greenhouses and hotbeds.

Description of garter methods

At the same time, there is a rapid growth of weeds, so it is necessary to weed the soil in 3 steps. Watering is carried out regularly on warm days with water at room temperature, even during the appearance of flowers. After the establishment of warm weather at night + 12 ° C, you can remove the film coatings and put them in storage.

Potassium chloride

Peat, humus and sawdust in a ratio of 5: 4: 1;

A warm greenhouse is a pit filled with biofuel (manure). It is better to provide a shelter for such a structure with a shed type. If we consider in more detail how to install it, then the work can be reduced to the following procedure:

It is believed that the optimal time for measures for the formation of bushes occurs when about 8-9 full-fledged, well-developed leaves appear on the cucumbers, and the length of the stem reaches 25-30 cm. injury to the plant.

Planting cucumbers in the greenhouse: highlights

We choose seeds for the greenhouse of self-pollinating varieties or parthenocarpic ones, and for open ground - any early ripening ones.

Self-pollinated cucumbers have flowers with characteristics of both sexes, i.e. pollinate themselves, they do not need bees - Zozulya F1, Cupid F1, Orpheus F1, Cheetah F1 and others.

How the soil is prepared

Lack of nitrogen leads to poor growth, leaves and other organs first acquire a pale green color, and then turn yellow and die off. Symptoms of nitrogen starvation appear first on the lower leaves. It should be borne in mind that the leaves can turn yellow in the same way when shaded. Lack of nitrogen also leads to the fact that leaves, shoots and fruits become smaller.

Seedlings of cucumbers for a greenhouse can be grown in home gardens or in an already prepared greenhouse with an additional heating source. Seedlings should be planted in unheated film greenhouses no earlier than May 10-15. At early planting dates, the planted plants can fall under frosts, which in our zone are possible until the first ten days of June (inclusive). In this case, you must have at the ready means of protection.

The temperature inside the greenhouse must always be at a certain level. Before fruiting begins, the temperature should be at least 20 degrees, and at night - at least 17 degrees.

Better look

In a similar way, it is possible to grow not only cucumbers, but also tomatoes. The seedlings in the greenhouse are well received due to the preheating of the soil and the necessary moisture. At the same time, you can harvest a good harvest of vegetable crops at an earlier date.

Greenhouse installation: types and main works

Humus, sod land and fresh mullein - 7: 2: 1.

Warm greenhouse: making

Dig a trench of arbitrary length depending on the size of the frames, and it is better to lay the width equal to 1.5 m. The optimum depth is 50 cm. The shape of the pit should be of a truncated cone pointing downwards.

There are several basic techniques for tying cucumber loops. Each of them has its own characteristics, advantages and disadvantages.

1. Cucumbers are planted in a greenhouse earlier than in an open garden, about a month.
2. Parthenocarpic cucumbers form ovaries without any pollination on all flowers. They are hybrids and do not have seeds - Picnic F1, Pyzhik F1, Premium F1, Suzdal F1, etc.
3. In greenhouse vegetable growing, there is almost no excess of phosphorus and potassium. Phosphorus starvation in greenhouses is rare. Usually, there is enough phosphorus in the greenhouse soil, and the plants take it out of the soil a little. With a lack of phosphorus, the leaves of the cucumber become small, intensely green in color with a bluish tinge. Dried leaves are almost black in color. Plant growth slows down.Similar symptoms also appear with an excess of moisture and a lack of oxygen in compacted soil, as well as with a cold snap.

• In the selected version of the mixture for the soil, it is necessary to add ammonium nitrate - about 10 g, superphosphate - 10 g and potassium chloride - 5 g. In this case, it is necessary to carefully use the mullein, since this fertilizer gives the soil an excessive density. If plants are planted in soil with such a mixture, then its root system will not be able to germinate through the formed crust.
• Along the sides of the foundation pit, install parubni (logs, boards or other building material) so that their level on the north side is about 20 cm higher than the south side. These elements must be fastened at the ends and in the middle with the help of boards. On the steamer on the south side, you need to make grooves or nail small blocks in order to secure the frames well.
• Vertical method. The name is due to the use of special horizontal supports for the garter at a height of about 2-3 cm from the ground. The tapestry looks like the letter "P". Ropes for tying cucumber tendrils cling to its top bar.
• With morning frosts, cucumbers in the greenhouse do not need to be covered, but in the open field it is necessary.

Let's take the middle part of Russia. Spring is both early and late here. Therefore, cucumbers, if you want to eat them early, will have to be grown in a greenhouse. It is only later, at the end of June, that the grown seedlings can be planted in a garden bed under the open sky. These cucumbers, of a later harvest, will keep well when salted.

Sowing seeds: highlights

With potassium starvation, symptoms appear first from the edges of the lower leaves. They turn brown, then dry up, and the entire leaf dies off. This is the so-called marginal burn or "opal". The growth of internodes stops, and many deformed fruits - "hooks" appear. It should be noted that "hooks" can also appear with incomplete pollination.

- this is a crucial stage of work. As soon as the weather permits, and as soon as the soil and soil in the greenhouse warms up enough, holes are made in the beds, according to the planting scheme. Before planting cucumbers in a greenhouse, the holes are spilled with a warm weak solution of potassium permanganate, and then with warm water. Seedlings from pots are planted in holes so that the surface of the coma is 1–2 cm above the ground level. The root collar should not touch the ground, where there is always an infection, and also it should not suffer from water flowing down during irrigation. This completes the planting of cucumber seedlings in the greenhouse.

• In clear weather - 28 degrees;
• Where qualified specialists will share their secrets and personal experience.

Growing seedlings: the main rules

Planting cucumber seeds is usually done one in each cup to a depth of about 2 cm, which is covered with sawdust, sand or earth on top. In this case, the container for planting can be made of thick paper or several layers of newspaper, cutting them into ribbons 14 cm wide and 50 cm long, and each tape can be wrapped separately with a bottle with a diameter of 8 cm in one and a half turns. To fix the shape, it is necessary to release the paper slightly below the bottom and bend it, and remove the bottle.

At the bottom of the trench, a layer of insulating material should be laid out and a layer of biofuel should be evenly laid on top to the top, while in the center it should be slightly compacted.

Horizontal method. With this method of garters, two trellises with a height of about two meters are used. These supports are located on both sides of the cucumber rows, after which several horizontal rows of strong rope are attached to them, on which the cucumber loops are tied.The disadvantage of this method is that the plant stops growing, barely reaching the first horizontal row. On the other hand, the garter method is compact and prevents additional shading.

• In the greenhouse, the ridges must be cooked in the fall.
• When the first greenhouses in the open air are ready for use, there will still be a little time before the start of the autumn cold snap. It is enough to harvest and salt it several times.
• In greenhouses, magnesium starvation is sometimes observed, which manifests itself in the form of chlorosis. In this case, the leaves brighten: the tissue between the veins of the leaf turns yellow, and the veins themselves remain green.

It is allowed to plant cucumbers in the greenhouse with seeds. However, this increases the time before the start of fruiting. Therefore, it is rarely used. The planting method is similar to that described for planting seedlings. Only a seedling is not introduced into the hole, but seeds.

Top dressing of seedlings: how to make fertilizer compositions

On cloudy days - 23 degrees.There are 6 sprays per season.

How to grow and harvest a good harvest of cucumbers without any problems?	10-12 g	Agrotechnical techniques used in the cultivation of cucumber: 1 - sowing seeds on a damp paper towel, 2 - transplanting sprouts into pots, 3 - planting plants in a permanent place, 4 - pinching the top, 5 - pinching the side shoots, 6 - collecting fruits (cut : with a sharp knife).	Cover with frames and mats for several days (up to 5), during which time the manure layer will slightly decrease. Therefore, it must be supplemented, compacted and covered with a layer of earth about 20 cm from above. The greenhouse is ready, and when a warm microclimate is established, you can plant cucumbers with cucumbers directly in this prepared soil.
Formation into several shoots. This method of tying cucumbers has appeared relatively recently and has not yet become widespread, like other methods. Its essence lies in the fact that the lateral shoots of a cucumber bush, when ovaries appear, are attached not to a special support, but directly to its own stem. To do this, the antennae attached to the central shoot is twisted around the lateral one several times. In this case, you need to carefully monitor that the angle located between the stem and side shoots is at least 60 degrees, since otherwise there is a high probability of injury to the plant and deformation of the cucumber bush. The garter is made slightly below the level of the ovary. During the growth of the lateral whisker, the procedure will need to be repeated several times, removing unnecessary shoots and branches as necessary. So the plant will not waste extra energy and nutrients, which will be used for the formation of fruits, which will ensure their higher quality and excellent yield.	And, of course, cucumbers will grow in the greenhouse and will be ready to eat much earlier than in the open field.	Grown seedlings (see below) can be planted in the garden without shelter, not earlier than the threat of "matinees" - morning frosts has passed. Cucumbers do not tolerate frost at all, even a slight one.	Noticing the symptoms of a lack of certain elements, it is necessary to give them in top dressing. So that the soil always has a supply of nutrients, the first top dressing should be carried out 25-30 days after planting the seedlings, that is, at the very beginning of fruiting. Further feeding is carried out every 7 to 10 days. For top dressing, you can use mineral fertilizers available on the market: ammonium nitrate, urea, ammophos, superphosphate, etc. It is undesirable to use potassium chloride and potassium salt, since the cucumber reacts negatively to chlorine. Of potassium fertilizers for cucumber, potassium sulfate (potassium sulfate) or potassium nitrate (potassium nitrate), containing both potassium and nitrogen, are better suited. The composition of complex fertilizers includes the main nutrients - nitrogen, phosphorus and potassium, and in some of them - magnesium ("Kemira") and microelements (PUM-1).
Caring for cucumbers in a greenhouse consists in forming a bush, watering, feeding and pinching in time. A cucumber is formed into one stem. After 3-5 days after planting, the seedlings are tied to trellises. As the plants grow, the stem is regularly twisted around the twine through each internode. Branching and vegetative growth are limited by pinching.	It is not easy to grow cucumbers with your own hands; you will have to monitor the temperature not only of the air, but also of the soil. Sudden temperature changes can cause plant diseases. Among other things, this can spoil the taste of the cucumbers. This article will tell you about various diseases of cucumbers in greenhouses.	The following solution, made by hand, will help from yellow spots: 10 liters of water, 30 g of copper oxychloride. Disinfection of the soil also occurs if you pour boiling water over it 2 times.	What could be better in the autumn - winter period of fresh young cucumbers for salad? This is the most beloved vegetable by all, which yields more in the greenhouse than in the open field.

Planting seedlings in a greenhouse structure

When you need to grow healthy plants with strong and well-developed roots and dark green leaves, it is better to grow cucumbers and tomatoes in heated soil under a film or plant in a greenhouse. This process is feasible in room conditions, but this requires a well-lit room and a temperature regime of at least 18 ° C. At the same time, in the room, the seedlings of cucumbers must be kept for no more than 20 days, in the greenhouse structure - up to 30 days, but before the flowers appear. In contrast, tomatoes need to be planted in 50-day seedlings.

A greenhouse with a film cover does not require special skills and a lot of effort, while growing plants such as cucumbers and tomatoes under film on unheated soil yields a harvest 15 days earlier than if they are planted in open soil. Before planting plants, you need to set up a greenhouse in advance, about 5 days in advance, so that the earth has time to warm up. For the cultivation of cucumbers, metal frames are often used, mainly arcs and a dense film.

1. Blinding method. An old, popular and favorite way of gardeners. Differs in extreme simplicity and efficiency. For a garter by the method of blinding, it is necessary to install one vertical trellis and tie a cucumber stalk to it. As for the antennae and lateral shoots, those of them that are located half a meter from the ground level must be removed. This manipulation greatly contributes to the formation of a strong and stable central shoot, and also has a positive effect on yield indicators. The plant is tied up approximately under the second lower leaf, not forgetting that you need to leave a loop supply. Indeed, as the bush grows, its central shoot will also increase, and a too narrow looped grip can cut off the plant's nutrition.

3. With morning drops in temperature, the beds with cucumbers must be covered with foil. When the air temperature rises, we remove this film, otherwise the cucumbers will “steam up”, which also has a bad effect on their health.

Growing cucumbers in a greenhouse

Good results are obtained by feeding with completely soluble ballastless complex fertilizers such as crystallin or crystallon (with different ratios of macro- and microelements). Different brands are used depending on the phase and condition of the plants. Magnesium sulfate and microelements in tablets are on sale.

The varieties grown in film greenhouses are formed in approximately the same way. The crown of the main stem is pinched when the stalk outgrows the trellis by 20-30 cm. The lateral shoots (branches) emerging from the axils of the leaves on the main stem are pinched in different ways. The lower 2-3 sinuses "blind", that is, they pluck out the lateral shoots in them, as well as all male and female flowers.The lower ovaries grow very slowly, are often ugly and only draw off nutrients, inhibiting the vegetative growth of the entire plant as a whole. In the next 5–6 lateral shoots located in the lower part of the stem, it is necessary to pinch over each first leaf (counting only one fruit on each shoot). In the middle part of the stem, the shoots are pinched already above the second leaf (for 2 fruits), and in the upper part of the trellis - above the third leaf (for 3 fruits).

The humidity inside the greenhouse should also be monitored. Before the beginning of fruiting, it should reach 80%, during fruiting - already 90%. We recommend reading the article on combining plants in a greenhouse according to all the rules.

Powdery mildew is helped by spraying with a solution of potassium permanganate or soda ash.

Growing cucumbers in a greenhouse is not difficult and very interesting. It is only necessary to take into account a few simple rules, and there will definitely be a rich harvest.10-20 gObservance of the temperature regime is necessary:

Heated, disinfected or treated with microelements, the seeds are kept on a damp cloth, at a temperature of +20 + 25 ° C, until they swell completely

Cucumbers are the most common vegetable crop that can be cultivated both outdoors and indoors. Although these plants are not high in calories, they are very healthy due to the content of beneficial minerals and vitamins. At the same time, cucumbers have the ability to increase appetite and improve the functioning of the digestive system; they are also recommended for various diseases. You can provide your diet with such fresh vegetables if you grow them in a greenhouse.

First of all, it is necessary to properly prepare the planting soil for cucumber seedlings. It is recommended to do this in the autumn months. So, to obtain the most nutritious soil, you should mix the earth with humus and small sawdust, previously scalded with boiling water. Take the components in a 1: 2 ratio. A week and a half before the direct planting of seedlings, the soil base must be thoroughly moistened and additionally nourished by adding a glass of ash and 2 teaspoons of urea or superphosphate.

We plant cucumber seeds or already grown seedlings on a bed prepared in autumn. On the garden bed, we make vertical indentations for seeds up to 2-3 cm deep. We put 2 seeds there and cover with peat or fertile soil. For seedlings, we make holes deeper, depending on its height. Leave a distance of 9-11cm between cucumbers, 52-58cm between adjacent rows. Do not forget to gently water our plantings. We make sure that the water does not wash out the roots.

Cucumber plants absorb nutrients better when feeding them with liquid fertilizers. Since a cucumber does not tolerate a high concentration of soil solution, no more than 100 g of fertilizers (1% working composition) must be dissolved in 10 liters of water.

After the fruits are removed from the lateral axes of the first order, lateral shoots of the second order will grow on them from the axils of the leaves. It is better to remove these shoots in the lower part of the stem, in the middle part - they must be pinched above the first leaf, and in the upper part - above the second leaf.So, growing cucumbers inside a greenhouse is not an easy task, but every lover of vegetables grown with their own hardworking hands can cope with it. You can learn how to grow grapes in a greenhouse.

Cucumbers: care, illness, feeding

How and at what time are cucumbers planted.

Also, for prevention, it is necessary to do it yourself with dusting of fruits. Spraying with infusions of onion husks, tobacco, tomato tops, garlic, potato tops, etc. has also proved to be excellent. We recommend that you learn how to defeat cucumber pests in a greenhouse using folk methods.

The first step is to prepare the greenhouse and the soil. Cucumbers are susceptible to many diseases and are easily attacked by pests.Therefore, when growing a crop, the soil must be changed every season, otherwise the yield will significantly decrease.

20-30 g

In the period before the emergence of shoots - 26-28 ° C;In addition, the seeds of the plant must be hardened. To do this, they are placed in special gauze bags and soaked in ordinary water for 12 hours at room temperature (20 - 22 ° C). Then they are taken out and left in a room at a temperature of about 20 ° C for the seeds to germinate. As soon as they swell and small shoots appear, the bags are moistened and placed in a cold place (-2 ° C, -3 ° C) for 12 hours, and after that they must be kept at 18 ° C for about 6 hours.Cucumbers are picked unripe when they are still green.Then you can start preparing the seeds, but first you need to decide on the variety. Knowledgeable people advise to give preference to hybrids, which, due to their increased resistance to various diseases and high adaptability, are best suited for greenhouse cultivation. The most popular and fruitful among them are the following varieties: "Halli", "Lada", "Marinda", "Malachite", "White Angel F1", "Caprice", "Annushka".

Errors when planting seeds and seedlings

Planting cucumbers in the ground is also possible in holes, 2-3 seeds in each; from hole to hole we leave 45-49 cm of free land. We plant the seeds in the soil by 2-4 cm. Be sure to carefully water the planted seeds or seedlings.

In practical vegetable growing, organic fertilizers are also used for feeding: mullein, bird droppings, manure from other animals. To do this, they are soaked in water in a container, and allowed to wander for 2-3 days, stirring the contents from time to time. You can add a few glasses of wood ash to a bucket of fermenting fertilizer. The slurry is diluted in a ratio of 1 to 5, and bird droppings - 1 to 20. Superphosphate (50 g per 10 l) is added to the working solution of the mullein. In large greenhouse farms, organic fertilizing is not used in order to avoid the possible introduction of infections into greenhouse areas.

In the future, they do not adhere to a strict formation system, making sure that the shoots do not go out into the aisles, for which, if necessary, pinch their heads and direct them into the row. Simultaneously with pinching with a sharp knife, the antennae, lower yellowing leaves, sterile and fruiting shoots are removed.

The place for the greenhouse is chosen with a slight southern slope. It should not be exposed to cold northerly winds.

With the first shoots during the day, it is optimal to warm the air up to 20-22 ° С, at night - up to 18 ° С;

When cucumber seeds are hardened, they must be constantly moistened, and for this it is better to use special solutions instead of water to stimulate the growth and speed of seed germination and the appearance of flowers. There are several recipes for such compositions (the content of the substance per 1 liter of water is indicated here):

When planting cucumbers in the ground, it must be remembered that the stem of the plant does not give lateral roots.

The seeds of cucumbers will need to be carefully sorted out, choosing among them the largest (from 10 mm) and undamaged, and then kept in a concentrated solution of potassium permanganate for about a day. It is also recommended to harden, which will prepare the plant for possible temperature extremes. In order to harden the seeds, wrap the seeds in a damp cloth and place them in a cool place for a couple of days, where they will constantly keep from 0 to –2 degrees; at home, the lower compartment of the refrigerator is best suited for this purpose.

Formation of the fetus

When planting cucumbers with seedlings: in the first days, the plants need to be "shaded", i.e. protect from the bright sun so that its rays do not damage the delicate leaves, do not cause irreversible damage to them, from which the seedlings will die.To do this, you can break several branches of any shrub and stick seedlings near each bush from the sunny side.

With an alkaline reaction of the soil solution, at low soil temperatures, partial death of roots, and under some other circumstances, nutrients poorly enter the plant through the roots. In these cases, foliar dressings are used (through the leaves). Fully soluble ballastless fertilizers are more suitable for these purposes. The concentration of the solution should not be more than 0.5% (up to 50 g of fertilizers per 10 liters of water). Top dressing is carried out with caution: in cloudy weather - in the morning, and in sunny weather - in the afternoon, in the late afternoon. Sprayers are used that provide fine-droplet spraying. Foliar dressing can be combined with treatment against pests and diseases.

We monitor humidity and temperature

When growing bee-pollinated varieties and hybrids, it is necessary to provide access to the greenhouse for bees and other insects. On hot summer days, bees are reluctant to fly to the greenhouse. They are attracted by feeding them with sugar syrup infused on the corolla of male flowers.

+ 1 # 1Katerina 03/05/2015 17: 49A I tried to plant the early ripening variety Nastya F1. I watered it with a watering can, we did the ventilation ourselves. The most difficult thing was to regulate the temperature, our weather is unstable - during the day it was +35 degrees, and at night it dropped to +10 degrees. The cucumbers grew very quickly — counting. we did not suffer with seedlings. immediately planted in the ground, 43 days, a short period. The cucumbers were just crooked, apparently, they weren't watered enough. But the variety itself is very productive (we collected 3 buckets of 10 liters per day), the fruits are tasty and juicy. small pickling varieties. For such a greenhouse is much better. At the same time, I'm talking about growing for myself, of course, and not about greenhouse farms - they have their own technologies, but the taste is no longer the same. And covered with oilcloth in case of frost. But then my husband and I built a simple but large enough greenhouse. And first of all, I planted cucumbers there. The harvest cannot be compared with the open field. And it ripens earlier. You can feed children with vitamins all summer. Quote0 # 4Tatiana Matyash 03/18/2015 20:25 We have many greenhouses, in one of them we plant cucumbers. They are obtained before anyone else. But I immediately put them in cups, then when they grow up a little I plant them in the greenhouse. And I will definitely tie them up when they start. I choose different varieties for planting. Quote0 # 5Mikhail 05/13/2015 12:42 PM I have been growing cucumbers in a greenhouse for more than 10 years. Contrary to the opinion of many about that. that only salad varieties of cucumbers can be grown in the greenhouse, I grow 3-4 varieties in my greenhouse. To prevent fluctuations in soil temperature, I use bioregulation. For tall varieties, I do the dropping of lashes. When the height of the lashes reaches 2 - 2.5 meters, I lower the trellis so that the tops of the stem, thrown over the trellis by 10 - 15 cm, lay on the ground. Then I sprinkle the stem with earth, without covering the top. The stem takes root and begins to actively grow again.

• Cucumbers are quite unpretentious plants, the main thing is to apply fertilizers and water on time. Before the beginning of fruiting, watering is carried out every three days, about 7 liters of water are consumed per 1 m2. As the cucumbers grow, the watering increases. During fruiting, the plants will have to be watered once a day.
• First you need to prepare the greenhouse itself. Disinfection is carried out using a solution of bleach. Also, the greenhouse should have a thermometer, it should be ventilated and, if necessary, provide shading.

In the case of the development of weak seedlings, which can be determined by the pale color of the leaves of the plant, it is necessary to feed the soil with organic fertilizers, while their preliminary preparation is carried out. To do this, you need to fill a container (barrel or tank) with manure halfway and top up with water. This solution is left to stand for about 2 days, while the mixture must be stirred to remove ammonia and hydrogen sulfide emissions. For use, the solution is diluted in a ratio of 1: 8 when using mullein, 1: 6 - manure and 1:10 - when using bird droppings. You also need to add superphosphate to the bucket for about 20 g.

On the 6th day of growth - 20-24 ° C.

20 mg boric acid;

Before sowing seeds in the greenhouse, soil preparation must be carried out. At the same time, this should be done in early autumn, immediately after harvesting. This is due to the fact that in the warm season, more nutrients and moisture accumulate in the soil, in a dug area.

Before planting cucumbers, the soil in the greenhouse should be properly prepared, having previously saturated it with mineral and organic fertilizers. You can also add manure, humus, sawdust to the soil. After feeding, the ground must be carefully dug up (about 25 cm) and covered with a protective film, which will allow it to warm up well and absorb the nutrients you have introduced as much as possible. After a couple of days, you can go directly to the process of planting cucumbers.

To get a harvest of cucumbers early, they are planted in greenhouses. But first, seedlings are grown (see below). It can be grown both on a windowsill and in a greenhouse. Only on the windowsill it is easier to do this - less time will have to be devoted to caring for the plants.
