Zelentsy are not prone to yellowing and significant overgrowth. A hybrid is characterized by the presence of complex resistance to major diseases. Resistant to olive blotch, common cucumber mosaic virus, tolerant to root rot.
The value of the “April f1” hybrid form is the friendly formation of the crop during the first month of fruiting. Yields in the first phase of the growing season with proper care reach 7-13 kg / sq. m. The best fruiting is observed in the presence of pollinating insects and early planting, which allows to increase yield by about 25-30%.
Presowing seed treatment
Planting material for cucumbers "April f1" is distributed by several seed companies and agricultural firms. Original seeds are produced by the selection and seed-growing company "Manul". The quality and quantity of seeds must always comply with GOST R 52171-2003. Preplant seed preparation consists of the following sequential measures:
- sorting and selection of the highest quality seeds;
- the process of heating the seeds;
- preventative seed dressing or disinfection;
- germination of seed material with subsequent hardening.
Potassium permanganate is most often used for disinfection, the crystals of which should be diluted in warm water at the rate of 10 g per liter of water. In such a slightly pink solution, the seeds are placed for 30 minutes, after which the seed is thoroughly washed under running water. For dry disinfection, you can use drugs such as NIUIF-2 or TMTD. It is advisable to carry out additional seed treatment with special biostimulants that improve growth and accelerate plant development.
Cucumber "April f1": features of the variety
Cucumber "April f1" is allowed for cultivation in the Northern, Central, Central Black Earth, Middle Volga, North-West, Volga-Vyatka and North Caucasus regions of Russia. This vegetable crop shows the best yield when grown in protected ground conditions. The density of planting of cucumbers on ridges of covered ground should not exceed 2.5-3 plants per square meter. Planting cucumbers can be carried out by seeds and seedlings.
A great alternative to purchased vegetables is the April f1 cucumber grown at home. However, there are some subtleties of planting hybrid cucumbers in an apartment or on a balcony. In a wide flower pot filled with a soil mixture for vegetable crops, it is necessary to plant the seeds that have been pre-sowed, and then cover the pots with foil. Cucumbers are best planted in 2-3 pcs. seeds in each pot.
It is recommended to pinch the central shoot at the very top of the trellis structure, and pinching of the side shoots is carried out above the third or fourth node. It is necessary to collect Zelentsy at least three times a week. Pinching is also an important procedure when growing cucumbers at home.
When growing the cucumber "April f1", top dressing should be carried out in a timely manner, which should compensate for the loss of nutrients in the soil and extend the fruiting period of this vegetable crop.
|Fertilization dates||Application rate||Ammonium nitrate g / l||Superphosphate g / l||Potassium sulfate g / l|
|Before the fruiting phase||10 l for each square meter of landings||0,5-1||2||1|
|At the fruiting stage||10 l for each square meter of landings||1,5-2||2||2|
When growing the April f1 cucumber in protected ground or in an apartment, you should carefully consider the temperature regime, the observance of which will determine the fruiting duration, as well as the quantity and quality characteristics of the crop.
|Vegetable development phase||Daytime Indicators||Indicators at night|
|Before the phase of the appearance of the five true leaves||20-22 ° C||16-18 ° C|
|Flowering stage||26-28 ° C||24-26 ° C|
|At the fruiting stage||28 ° C||18-20 ° C|
It is important to remember that at a temperature of +15 ° C, plant growth is inhibited, and at +10 ° C it completely stops. Cucumbers die at a temperature of + 6-8 ° C. If the temperature drops to +18 ° C during the day or rises to + 36-40 ° C, then there is no formation of ovaries. Throughout the entire growing season, regular inspections of plants should be carried out for damage by diseases or pests. For prevention, you can spray with folk remedies or chemicals.
|Remedy||Indications for use||Consumption rate||Method of use|
|Quadrice||Powdery mildew, peronosporosis||0.04-0.06 percent working solution||Before flowering and after flowering with an interval of 14-16 days|
|"Ridomil Gold"||Late blight and alternariosis||2.5 l / ha||2-3 times per season, with an interval of 10-14 days|
|"Topaz"||Powdery mildew||2 ml / 10l of water||Three treatments during the growing season|
Timely harvesting is an important component of growing hybrid cucumbers. In addition to collecting already ripened greens, it is necessary to remove all diseased or deformed fruits in order to prevent mass infection and death of plants.
Cucumber "April f1" due to the presence of parthenocarpy forms a high yield in greenhouses, where the number of pollinating insects is minimal. The hybrid is distinguished by self-regulating branching, so its cultivation is not difficult even for beginners. Limited lateral branching does not require gardeners to regularly pinch and pinch.
How to care for cucumbers in a greenhouse
