Description
"April F1" is a hybrid of the first generation and belongs to the category of parthenocarpic, that is, it does not need pollination (the ovaries grow without fertilization). It is noticed that with the participation of insects pollinating the female flowers of this hybrid (especially with early planting), its yield increases by 25-30%.
The hybrid has a high yield, which makes it cost-effective for commercial production
The plant is indeterminate with limited lateral branching, has a purely or predominantly female flowering type. In terms of ripening, it belongs to early ripening: it bears fruit on the 40-45th day after the emergence of full shoots. During the entire long period of fruiting, it is characterized by a friendly return of the crop. Its ability to give a plentiful early harvest is especially noted - during the first month up to 7-13 kg / m2.
Zelentsy of medium length (from 13-15 to 22-25 cm), weighing 160-300 g, are similar in type to Zozula F1: they have a cylindrical shape, bright green or dark green color with short light stripes, ribbed, infrequently covered with medium-sized tubercles. It is recommended to collect greens at least once every 2-3 days, otherwise the peel may become coarse.
Zelentsy are considered salad greens, but many use them for preservation. The main secret is not to put cucumbers of different hybrids in jars.
The hybrid is appreciated for its high resistance to diseases, endurance to adverse weather conditions and unpretentious care:
- resistant to olive spot (cladosporium) and cucumber mosaic virus;
- tolerant to root rot;
- possesses relative cold resistance and shade tolerance.
Cucumbers are planted in standard ways: direct sowing of seeds into the ground or seedlings. The recommended planting density is no more than 2-3 per 1 m2. Like all hybrids, the April F1 has a set of all valuable qualities that is stable only in the first generation, that is, seeds must be bought for each season.

How to plant?
Terry varieties of petunias are best planted by cuttings. When planting, the soil should be well dug up and moistened. The plant must be covered with foil or glass so that the soil remains moist for as long as possible. The condition of the soil should be monitored on a daily basis. The transplant can be done with the appearance of the first leaves (3 pieces). If the plant has 5 leaves, then it must be pinched.
With the onset of the warm season, at the end of March, petunia is planted in open ground. The distance between the plants is about 26 cm. The first flowers will appear in 2.5 months. Before the onset of cold weather, plants are treated with special substances that counteract the vital activity of such pests:
At the very end of January, cuttings (11 cm) are cut from the tops, immersed in a phytohormone solution for 3 minutes, this will help the roots to develop better. After that, the plants are installed in moist soil, covered with foil.
With the onset of heat, containers with plants can be taken out to the loggia so that they breathe fresh air, from this they will become more hardy.
Description
The "Connie F1" hybrid of cucumbers is parthenocarpic, that is, it does not require the participation of pollinating insects for the formation of ovaries and fruit filling. (Many people mistakenly call these hybrid forms "self-pollinating".)
All original varieties of cucumbers are dioecious, that is, they have heterosexual flowers and need pollination by insects that transfer pollen from male flowers (barren flowers) to female
Unlike bee-pollinated varieties and hybrids of cucumbers in parthenocarpics, the ovaries grow into green plants without fertilization, which significantly reduces the dependence of their yield on weather conditions and the presence of insects. Seeds in unfertilized green plants do not have embryos, therefore they do not ripen. This property has a positive effect:
- on taste: seeds are small and tender, without a coarse shell;
- on the marketability of the appearance: the fruits have almost the same size and color, do not outgrow, do not deform, do not turn yellow.
Even with pollination of parthenocarpics and full-fledged seeds ripening in them, it makes no sense to use such seed material for planting for the next season. All heterotic hybrids marked "F1" combine improved parental qualities and show them only in the first generation.
Note that the breeding of hybrids with stable parthenocarpic properties is an achievement of selection, not GMO.
Many plants exhibit a natural tendency towards parthenocarpic development of fruits (in addition to cucumbers, these are tomatoes, apples, pears, grapes, tangerines, etc.). And in parthenocarpic hybrids, this property was fixed at the level of a genetic trait.
Many people note the high early yield of the "Connie F1" cucumber hybrid
Of course, vegetable crops that do not need pollination are primarily intended for cultivation in protected ground conditions - under film shelters, in all types of greenhouses, where insect access is limited. Parthenocarpics in such situations are more convenient and profitable, as they provide stable high yields.
Although the hybrid "Connie F1" is declared as early maturing, it is more correct to call it average in terms of ripening, since fruiting begins on the 47-50th day from the moment of full sprouting.
Indeterminate cucumbers in greenhouse conditions are grown vertically, tying and wrapping lashes around a stretched trellis or net, forming bushes according to various patterns
The plant is indeterminate, that is, unlimited in growth, vigorous and vigorous with an average climbing capacity and foliage. The leaves are small, wrinkled, with regular crenate edges.
The type of flowering is female, which provides a large number of ovaries, which are often laid in bunches (from 3 to 9 pieces per node), and the absence of barren flowers.
Zelentsi of the "Connie F1" hybrid are distinguished by their small (gherkin) size and small tubercles often located on the surface.
Zelentsy are very short, gherkin type - 7-9 cm, proportional, cylindrical-oval, rounded in cross section. The average mass of greenery is 60-82 g, the taste is excellent, without bitterness. The surface is covered with small and frequent tubercles, the pubescence is white, thornless. The skin is thin, rich green, the pulp is dense, juicy, does not form voids during heat treatment. Zelentsy is used fresh (as salad), and is also salted and pickled.
Packages with seeds of a hybrid variety of cucumbers "Connie F1" from various manufacturers
The hybrid is appreciated for its resistance to powdery mildew and root rot, endurance in unfavorable conditions, for example, with temperature extremes, and unpretentiousness.
In the agricultural technology of cultivation, this hybrid is not particularly difficult: it is important to choose the right timing for sowing seeds or planting seedlings, watering and feeding plants in a timely manner, weeding weeds and loosen the soil. To obtain the maximum return and duration of the harvest, it is recommended to carry out the formation of the bushes.

What the P0171 code means
A P0171 code means the fuel system of the first head (bank 1) of the vehicle Nissandoes not work well or there is a loss of air tightness on this side of the engine. The fuel mixture becomes leaner - the engine is receiving too little fuel and too much air.
What are the causes of the P0171 code?
The P0171 code can be caused by:
- Faulty Nissan fuel pressure regulator
- The fuel pump does not create the correct pressure
- Clogged Nissan fuel filter
- Defective engine control unit
- Air leaks
- Defective injector (s)
- Defective oxygen sensor in Nissan car
- Faulty MAF sensor
What are the symptoms of the P0171 code?
- Loss of power
- The indicator "Check Engine" is on
- Nissan engine is not smoothly running. Float turns
- Engine has difficulty starting
- The engine will not start
If this error persists for a long time and the car Nissanis operated on a lean air-fuel mixture this will damage the catalytic converter (catalyst).
How is the P0171 code diagnosed?
Assuming no other DTCs exist, you can diagnose the P0171 code by checking the engine for vacuum leaks with a vacuum gauge and checking the fuel system pressure with a pressure gauge.
Most likely, the cause of the error will be found during these two tests. If the reason is not in the fuel system and not in excess air, then the next step is to check the MAF sensor of the Nissan car (mass air flow sensor) and oxygen sensors (lambda probe).
If all these tests were performed and no problems were found, then most likely the fault is in the Nissan engine control unit.
Common mistakes when diagnosing the P0171 code
The most common mistake that can be made when diagnosing the P0171 error code is the lack of service bulletins for a specific vehicle model. Although not every model has a TBS for this error, it is always wiser to check it and save time and effort.
How serious is the P0171 code?
The P0171 code is a serious problem. If this error is stored in the ECM, then the vehicle's engine will not maintain the correct air-to-fuel ratio. While driving, there will be a loss of power and increased fuel consumption. In order for the car to work normally, the malfunction must be eliminated as soon as possible. Improper operation of the engine for a long time can lead to more serious malfunctions, which will require much more money to be eliminated.
What may need to be repaired to fix the P0171 code in a Nissan car?
- Replacing the fuel pump
- Replacing the fuel filter
- Nissan fuel pressure regulator replacement
- Replacing the engine control unit
- Replacing one or more injectors
- Replacing one or more Nissan oxygen sensors
- Replacing the MAF sensor
- Air leak repair
