How to grow parthenocarpic cucumbers in a greenhouse?

The seeds are sown in the soil at the end of November. Before that, they need to be warmed up (several days at a temperature of 50 degrees and one more day at a temperature of 70 degrees). A very good effect for accelerating growth is given by soaking the seeds in a special solution, which is prepared as follows: for one liter of water, you need to take one hundred grams of copper sulfate, boric acid and manganese and zinc sulfates, as well as about 20 mg of ammonium molybdate. Seeds of parthenocarpic cucumbers must be placed in the prepared liquid for 10-12 hours, after which they must be thoroughly dried.

To obtain seedlings, seeds are sown to a depth of 2-3 cm in peat pots. After the appearance of the first shoots, it is necessary to provide additional lighting and moisture saturation (a sprinkler system is used).

Seedlings are planted after the appearance of the fifth or sixth leaf, the height should be at least 25-30 cm.Caring for parthenocarpic cucumbers involves applying complex liquid fertilizers at the root. It is imperative to observe the appropriate temperature regime (at least 18 degrees Celsius at night and about 25 degrees during the day).

Formation of parthenocarpic cucumbers

Many summer residents and gardeners are interested in - is it necessary to pinch parthenocarpic cucumbers? One of the main conditions for their good growth is the regulation of the density of the bush. This is accomplished by pinching.

Most varieties of parthenocarpite cucumbers have an increased ability to form young shoots and if you do not produce timely formation, then very soon there will be no free space in the greenhouse. In addition, most of the nutrients will be spent on the formation of new lashes and ovaries, and the fruits will ripen slowly. This, of course, will affect the quantity and quality of the crop. How to form (pinch) parthenocarpic cucumbers? It is known that the pinching of the central whip in simple (non-hybrid) cucumbers is performed over 5 leaves in order to form new lateral shoots and thus reduce barren flowers, since male flowers are formed mainly on the main stem.

In parthenocarpic hybrids, flowers are concentrated precisely on the main lash, so you should not pinch it over 5 or 6 leaves. The pinching of parthenocarpic cucumbers is carried out as follows: in the axils of the first five leaves, blinding is done - shoots and flowers are removed. Further, about 6 lateral shoots are left. Their length should not exceed 20-25 cm.The next several shoots are also pinched, leaving a length of 35-40 cm.Further - 45-50 cm.The central main lash must be fixed on the trellis and when it reaches its maximum length, either pin the top, or carefully wrap down.

Review of the best varieties of parthenocarpic hybrid cucumbers with photos and descriptions

The variety received a lot of positive reviews, thanks to the good taste of Zelents. Many housewives use them for making salads and canning them. The plant is resistant to growing in the shade, therefore it is ideal for summer-autumn circulation. To get an early harvest, timely pinching of the side shoots is necessary. Cucumber variety F1 Arina is resistant to many diseases.

Some vegetable growers still do not know what parthenocarpic cucumber varieties are and how they differ from others. Why are these varieties recommended for indoor or indoor cultivation? After all, there are self-pollinating varieties of cucumbers that bear fruit just as well without pollination by insects. That's right, self-pollinated cucumbers also yield crops in greenhouses, but their quantity is significantly inferior to modern hybrids. You need to know that, strictly from a scientific point of view, parthenocarpic varieties do not exist, there are only artificially bred hybrids. Such cucumbers do not have seeds; it is impossible to obtain seed material from the harvested crop. Only special scientific farms are engaged in breeding hybrids and supplying seeds to consumers.

Parthenocarpic varieties of cucumbers for the greenhouse

Benefits of parthenocarpic hybrids

The new cucumber hybrid in all respects has left far behind its competitors. Thanks to its undeniable advantages, it is gradually replacing the usual varieties, both from indoor and outdoor fields. How are these hybrids different?

Possibility of year-round harvesting. In greenhouses, such cucumbers are grown in the cold period of time, depending on the climatic zone, the harvest time reaches eight or more months.
Harvest all year round
An excellent presentation of the crop. All cucumbers are the same size and color, there is no need for pre-sale preparation and sorting. In addition, they are perfectly preserved without additional protective treatment.
Taste qualities meet high modern requirements. The rind is thin, without unpleasant bitterness. In terms of the composition of mineral substances, it is in no way inferior to the usual varieties.
Versatility of use. Cucumbers of parthenocarpic hybrids are also suitable for the preparation of fresh salads and for pickling.
Cucumbers can be eaten fresh or pickled
The skin never turns yellow. This process is observed in common cucumbers during the full maturation of the seeds. Hybrids without seeds, which means there is nothing to ripen and there is no reason to turn yellow. This property allows them not to lose their appearance and taste for a long time.

The disadvantages include high exactingness to agricultural technologies. All plant hybrids have low vitality rates, this applies not only to cucumbers. But science does not stand still, the most modern hybrids in these qualities are no different from the usual varieties of cucumbers. As for the exactingness of adherence to agricultural technology, domestic farmers are already beginning to understand that only through such an approach can one get stable profits. By the way, summer residents also understood this, today they pay due attention to training and adherence to agricultural technology.

Parthenocarpic hybrids require strict adherence to agricultural technology

The most common parthenocarpic cucumber hybrids

We will not consider all hybrids, there are quite a few of them. Let's talk only about those that are often used in our country. All hybrids are marked with F1 on the packaging, indicating that they are parthenocarpic hybrids of the first reproduction.

Masha F1

Cucumber Masha F1

It has a thick stem, the length of cucumbers reaches 8-12 centimeters. One of the earliest ripening hybrids, fruits can be harvested 37–42 days after sowing. This hybrid grows equally well both in greenhouses and in open beds. High-yielding, excellent resistance to most diseases, cucumbers keep well, are characterized by excellent taste. The disadvantage is the difficulty of acquiring high-quality seeds, due to the great popularity, cases of counterfeiting have significantly increased. Experienced growers strongly recommend ordering seeds directly from growers via the Internet.

Herman F1

Features of the variety Herman F1

An early ripening hybrid, fruiting occurs on the fortieth day after planting. They have a high yield, cucumbers are tied in bunches (bunches) of up to eight pieces in one - such a hybrid grows in one stem, which greatly simplifies the process of harvesting and caring for plants.

Subject to the recommended agricultural technology, the yield is at least 20 kg per square meter - the efficiency of using greenhouse areas increases.

Herman's fruit is dense - has good keeping quality - it can lie down without turning yellow, and it goes into salting - void in pickled cucumbers is not formed

Disadvantages: instability to lower temperatures and poor pick tolerance. When the temperature drops below the critical value, the vegetation and fruiting of plants are suspended. The seedlings are very weak, during the picking, the root system is damaged, the development of cucumbers is noticeably slowed down, the plants are sick for a long time. You need to sow the seeds separately in special cups, which will make it possible to avoid the picking process.

Courage F1

Features of the variety Kurazh F1

According to many consumers, it is the most successful hybrid, especially for novice farmers and summer residents. Differs in high survival rate in various climatic conditions and high resistance to a wide range of diseases. It tolerates both too low and too high temperatures, requires less time and money for growing. Withstands a short-term drop in temperature to + 1–2 ° С, in such conditions it does not die, but stops growing. When the temperature rises, the growing season is resumed. Unlike other hybrids that are sensitive to watering intensity, they survive excess and lack of moisture well. Fruits have a thin skin, size 10-12 centimeters, are characterized by excellent taste.

One of the few hybrids that give good yields in low light, versatile growing method.Possesses high resistance to short-term temperature drop, in such conditions development only stops, the plant does not die. When the temperature rises, the development of the cucumber is completely restored.

Features of growing parthenocarpic cucumbers

During the cultivation of hybrid cucumbers, you need to take a set of measures for the emergence of powerful and healthy seedlings. For this, agronomists recommend doing the following operations:

pre-sowing seed preparation. The most effective way is thermal heating to t = + 50 ° С for three days, then the temperature is raised to + 70–75 ° С for one day. This heating mode destroys pathogens of viral diseases. To destroy fungi and bacteria, seeds are disinfected in special solutions. You can make them yourself or buy ready-made in specialized stores;
Presowing seed preparation
sowing seeds should be done at the beginning of December, but the specific dates depend on the climatic zone and the design features of the greenhouses. After the appearance of the first shoots, it is necessary to supplement the plants. The pick is carried out or not, taking into account the peculiarities of the hybrid.

Planting seedlings in the ground is performed thirty days after sowing, there should be no more than six true leaves on the stem.

Planting cucumber seedlings in open ground

The distance between the rows is about 160 cm, the first garter should be done on the third day after transferring the seedlings to the greenhouse.

Diagram of a vertical garter for cucumbers

The harvest of short-fruited cucumbers is done three times a week, for long-fruited cucumbers it is enough twice a week. With proper agricultural technology, the yield can be up to 30 kg per square meter of the greenhouse.

Video - Partenocarpic cucumber hybrids for the greenhouse

The use of parthenocarpic varieties with a long fruiting period when cultivating cucumbers in greenhouses allows for higher yields with less effort. This article presents a photo and description of varieties specially recommended for cultivation in a greenhouse.

Features of parthenocarpic varieties

Parthenocarpic hybrid forms are specially created by breeders for cultivation in greenhouses. Their characteristic feature is the ability to form fruits without pollination, and one of the main requirements for the variety, in addition to yield and long-term continuous fruiting, is high resistance to fungal and viral lesions typical of cucumbers:

powdery and downy mildew;
ascochitosis;
parenosporosis;
cladosporium disease;
spotting;
mosaic;
gray rot;
root rot;
rootworm nematode.

Cucumber "Cupid F1"

Attention! The advantage of parthenocarpic varieties, bred specifically for cultivation in greenhouses, is their high shade tolerance, which plays a significant role in the development of cucumbers in conditions of insufficient lighting, typical of home greenhouses.

Some of the hybrid forms recommended for cultivation form short lateral lashes that do not require pinching, but most paricarpic varieties require molding; for this, flowers and shoots should be removed from the axils of the first 5 leaves. The length of the remaining shoots should not exceed 20-50 cm. The central stem should be fixed on the trellis, and when it reaches its maximum length, it is either pinched or turned down.

Cucumber "Goosebump F1"

Most parthenocarpic varieties are lettuce varieties and are not suitable for canning. But thanks to the efforts of breeders, there are also universal varieties of parthenocarpics, which are easy to distinguish by black thorns.

Attention! Since partinocarp cucumbers produce fruits without pollination, the fruits themselves do not have seeds.

Cucumber "Alekseich F1"

Parthenocarpic varieties are classified according to ripening periods:

40 days - early maturing
45 days - mid-season
50 days - late maturing

The short growing season allows cucumbers to be planted in the greenhouse several times in a row throughout the year.

Parthenocarpic cucumbers for greenhouses - video

Parthenocarpic cucumbers gained popularity and began to be massively cultivated in private plots for a long time. Most often they are planted in greenhouses.

What is a parthenocarpic hybrid

Parthenocarpic varieties and hybrids of cucumbers are capable of forming ovaries without pollination. In the cut, such greens most often do not have seeds. In addition to seedless forms, parthenocarpic cucumbers with seeds are quite often found, which have a pear-shaped or hooked shape with a thickening in the area of concentration of seeds.

Parthenocarpic cucumbers have a number of advantages over other varieties and hybrid forms:

growth vigor and abundance of fruiting;
the absence of genetically inherent bitterness in greens;
continuity and duration of fruiting;
resistance to not too favorable weather factors;
resistance to attack by many diseases characteristic of cucumbers.

The advantage of such cucumbers, which is especially important when cultivated in a greenhouse, is the absence of the need to attract pollinating insects to plants. The few disadvantages of parthenocarpic hybrids include the presence of an ampelous structure of branches, which involves tying them to trellises, as well as the need to remove side shoots. In addition, one should take into account the fact that a significant part of parthenocarpic hybrids are unsuitable for canning and salting.

Landing rules

Parthenocarpic cucumber varieties can be planted either by seedlings or by ordinary sowing in a previously prepared soil.

Seed preparation

Before sowing, the seed should be prepared. To do this, the seeds should be warmed up for at least five days at a temperature of 50 ° C and during the day at a temperature of 70 ° C. Soaking seeds in a solution based on copper sulfate, pharmaceutical boric acid, manganese sulfate and zinc sulfate with the addition of ammonium molybdate is very effective.

Good results are provided by short-term soaking of seeds in a 0.5% solution of KMnO4. The soaking process lasts about 11 hours, after which the seeds should be dried.

Bacterial preparations based on the strains of Bacillussubtilis, Pseudomonas fluorescens and Ps. aureofaciens.

Soil preparation

For sowing and planting seedlings of parthenocarpic cucumbers, you should use areas with fertile, light texture, loose soil, which is well filled with organic fertilizers. Cucumbers need neutral or, in extreme cases, slightly acidic, well-warmed soil.

The most suitable precursors for such cucumbers are potatoes, onions, cabbage, tomatoes, and a variety of vegetable siderates, including alfalfa, clover, mustard, rye and oats.

Fresh manure is applied most often during the autumn digging of the soil, which allows you to structure the soil. The rates for applying fresh manure in the fall, depending on the qualitative composition of the soil, can be 6-9 kg per square meter. Mineral fertilizers are applied to cucumber ridges during spring digging. It is recommended to use ammonium nitrate at the rate of 15 g, superphosphates at the rate of 40 g and wood ash at the rate of 25 g per square meter. Complex fertilizers for vegetable crops are applied according to the attached instructions.

Dates and scheme of disembarkation

When growing seedlings, special attention should be paid to compliance with basic phytosanitary standards. For growing seedlings, containers with a volume of 0.7-0.8 liters are used. The seedlings should be 20-25 days old at the time of planting. Seedlings should have three or four healthy true leaves and a well-developed root system.

Sowing seed on open ground ridges should be carried out in the first decade of June, when there is no threat of recurrent frosts, and the soil is sufficiently warmed up. You can sow seeds on greenhouse beds two weeks earlier. The seeding depth is about 3 cm. The crops should be covered with foil to create optimal microclimatic conditions. Seedlings are planted according to the scheme 50-55 x 35-40 cm.

Care features

Most often, it is recommended to grow parthenocarpic cucumbers in greenhouse conditions, where it is much easier to create conditions optimal for plant growth and development.

Watering

Water for irrigation should only be warm, well heated in the sun. Before mass fruiting begins, cucumbers should be watered at least three times a week. After the ovaries have formed on the plants, the daily watering should be about 6 liters per square meter of the planting area. Watering is done at the root, after sunset.

Top dressing

The plants should be fertilized with mineral fertilizers twice a month. The optimal solution is the solution obtained by diluting 12 g of urea, 25 g of superphosphate and 18 g of sulfate or potassium chloride in a bucket of warm water. The standard consumption of such a solution is about 10 liters per 4 square meters of planting area.

High-quality, systematic foliar feeding of cucumbers has a good effect, for which it is recommended to use 4.5 g of ammonium nitrate, 9 g of superphosphate and 7.5 g of potassium sulfate per bucket of warm water. Spraying should be done in the evening.

Plant formation

It is allowed to carry out the formation of cucumber bushes after the appearance of nine true leaves. The main formation scheme involves the removal of all rudiments of branches and flowers on the main cucumber whip up to a height of half a meter.

Next, the lateral shoots, which have formed from the axils of the next five leaves, are pinched over the first leaflet, and all female flowers are removed. Above, it is necessary to leave about three or four ovaries on the stepsons and about five ovaries on the main stem. In this case, all unnecessary stepsons are necessarily removed.

Preventive spraying

To protect cucumber plantings from the main, most dangerous diseases, it is recommended to carry out the following preventive measures:

spraying during the growing season with a 0.1% solution of "Fitolavin-300";
watering at the root at the stage of formation of the 2-4th true leaf with a solution of "Fitolavin-300";
spraying with Alirin-B or Gamair-SP during the growing season.

A good result is the use of well-known folk remedies, among which the infusion of tomato or potato tops is especially effective.

Currently, the choice of varieties and hybrids of cucumbers is very extensive and can satisfy even the most discerning grower. Parthenocarpic cucumber hybrids are very easy to grow. They can be grown both by seedlings and by direct planting of seeds on ridges.

How to plant cucumbers (video)

Such hybrids show excellent productivity, excellent adaptation to growing conditions and form greens with very high taste and market characteristics. To get a really decent harvest of very tasty and beautiful green leaves, it is enough to adhere to the cultivation technique and not neglect the basic rules of care.
