In the middle lane, spring often presents unpleasant surprises: frosts suddenly return at the most inopportune moment. And then the early harvest of fruit crops should not be expected. How to collect delicious cucumbers in the second half of June?
Exist two ways:
- First, grow cucumbers through seedlings at home, and with the onset of consistently warm days, transplant them into the greenhouse.
- Immediately sow cucumber seeds in the greenhouse.
The second method is more effective than the first one in that it allows you to get less pampered and unstretched plants. But in this case, the seeds need to be sown at the end of April. At this time, in the middle lane, the soil still does not have time to warm up well, therefore, to obtain an early crop of cucumbers, it is necessary to construct a heated greenhouse or conduct special seed and soil treatment, and also choose varieties resistant to unfavorable growing conditions, in particular, to cold.
Recommended cold-resistant varieties: Siberian F1, Diva F1, Break F1, Navruz F1 other.
To improve the cold resistance of cucumber seeds and get the harvest as early as possible, it is necessary to resort to several techniques.
Proper seed preparation for sowing is an important component of success.
Wrap seeds of sprouted seeds with wet gauze and keep them in a refrigerator at about 0 ° C for two days. Then immediately sow the seeds in the greenhouse. But remember: it is very important that during hardening they do not hatch.
Use of growth stimulants
Before sowing seeds, keep them in a solution with a growth stimulator (Epin, Kresacin). And after sowing, once a week, spray the plants with Appin and a humic preparation (Rostock or Lignohumate).
Growing cucumbers in warm beds
Warm beds are recommended to be placed even in the greenhouse.
Cucumbers, whose roots are in heat, are much easier to tolerate lowering the air temperature, since the aerial part of these plants is less sensitive to cold than the root system. Therefore, using high beds, you will create favorable conditions for plants for rapid and proper development.
Preparation of "home" for cucumbers need to start more in the autumn. At this time, the upper part of the soil should be removed from the greenhouse and organic material should be placed instead (for example, a mixture of foliage, tops, grass and straw).
It is recommended to sprinkle the leaves with lime so that the soil does not turn out to be too acidic.
AT mid March in the greenhouse you need to make a layer of snow 15 cm thick. When thawing, it nourishes the soil with moisture. AT end of march the ground must be covered with black polyethylene (preferably in two layers). Because of this, it warms up faster and does not lose moisture.
AT early april polyethylene must be removed, and fresh manure must be brought into the greenhouse soil, dusted with sawdust and mixed thoroughly using a fork. Then, the resulting substrate should be evenly poured over boiling water, and upward put a layer of light fertile soil with a neutral or slightly acid reaction.
Approximately a week before the "settling" of cucumbers in the greenhouse, the seeds that hatch have to be sown in peat pots. And for two or three days - cover the ground with polyethylene so that the earth warms up. At the same time, mark the beds where the plants will be planted, set the arcs over them and stretch the dense covering material. Thanks to this design, the effect of a thermos will be obtained - the plants will be very warm.
Peat cups - great capacity for seedlings
Place the peat cups with seeded seeds in the marked grooves. If you planned to use these containers for other seedlings, then carefully remove all of them from the ground and put them in the hole.
Until there is hot weather outside, do not remove the arc with additional shelter. Do this only when the temperature in the greenhouse is not lower than 28-30 ° C.
Secrets of a good harvest of early cucumbers
To get a generous crop of cucumbers as early as possible, you need to carefully care for the plants.
- When the seedlings grow and get stronger, the soil around them should be mulched with humus or fallen leaves, collected in the fall. The layer of mulch should be between 3 and 5 cm thick.
- Proper feeding - the key to a successful harvest. Once every 5-7 days it is necessary to apply complex mineral fertilizers with trace elements into the soil. It is desirable that top dressing be in the form of an aqueous solution. For the best effect, huminates should be added to them once. At low temperatures, fertilizers should contain large doses of potassium. For good growth, cucumbers need nitrogen, but keep in mind that for these purposes it is not recommended to use slurry.
- Once every 15 days, the plants should be sprayed with growth stimulants (Appin or Citron) and fruit formation (Ovary or Bud).
- To the fruit tied not only on the main trunk, you need to remove the ovary and lateral whip from the first four leaves. This will allow the plant to form a good vegetative mass. Then pinch the side lashes already above the second or third sheet.
- Do not forget to promptly remove the yellowed leaves, as well as those that are located below the fruiting area.
- The main enemies of the cucumber crop are root rot, powdery mildew, olive spot, spider mite and aphid. To avoid these diseases and pest attacks, when watering, try to prevent water from entering the root collar. The resistance of plants to powdery mildew and spotting will be enhanced by spraying with Immunocytophyte or Gamar, and Fitoverm will save from aphids and mites.
We hope our tips will help you grow tasty early-grade cucumbers. But keep in mind that they are not suitable for storage, so freshly harvested Zelentsy should be eaten immediately.
