Residents of cold regions, as well as those who plan at least 2 harvests per year, it is worth thinking about building a capital greenhouse, covered with film, glass or polycarbonate and equipped with a combined heating system.

Most available option - a greenhouse covered with a film... It retains heat well, transmits sunlight. However, a fragile film quickly breaks and deforms; such a coating will have to be changed every year. Glass is more durable, but can crack under the weight of snow.

Growing secrets

How to grow eggplants in a polycarbonate greenhouse? Eggplant is not considered to be too capricious culture. They are resistant to pests, are fast growing, respond well to feeding. Even a novice vegetable grower can achieve success. The process begins with growing seedlings. You can buy it ready-made, but sown with your own hand has a lot of advantages:

  • profitability;
  • sprouts are stronger and viable;
  • the process of transplantation and survival is facilitated.

Eggplant prefer light and nutritious soil with acidity from 6.5 to 7.2. Too heavy and acidic soils can cause root rot of young shoots.

Purchased soil for seedlings is not suitable. There is too much peat in them, which does not give the seeds the strength for full development. It is better to compose the mixture for planting yourself using one of the following recipes:

  • a mixture of humus, garden soil and river sand (2x2x1);
  • peat, garden soil, sawdust (2x1x3);
  • compost, peat, garden soil, river sand (1x1x2x1).

The mixture must be calcined for the destruction of insect larvae and pathogens. After that, the prepared soil is spilled with a bio-solution of the "Baikal" type to restore useful microflora.

Superphosphate or other mineral fertilizers must be added to the soil mixture in a proportion of 20 g per 10 liters of soil. Instead of ready-made complexes wood ash can be used... During the growth period, the seedlings are watered several times with a solution of nitrogen fertilizers, which make it possible to ensure the formation of a bush with green mass.

It is most convenient to plant seedlings in plastic containers with cassettes. They retain moisture well and facilitate the process of replanting grown plants. The use of peat pots is undesirable.

The weak roots of young eggplants cannot grow through the walls, as a result of which the plants do not develop well. When to plant eggplant seedlings for the greenhouse? Sowing is carried out at the end of January or in February. For heated greenhouses, seedlings can be prepared earlier, plants for ordinary greenhouses are planted at the end of February.

To improve germination seeds can be soaked for 10-12 hours in a growth promoter, then wrap in a damp cloth and leave to peck.

The prepared seeds are sown in well-moistened soil. The seeds are not buried; they must be sprinkled on top with a thin layer of soil mixture. The seed container is covered with glass. Seedlings should be regularly sprayed with soft water at room temperature, moistening not only the ground, but also the air around.

For germination seeds need a stable temperature (20-22ºC), high humidity and bright light. It is recommended to arrange the backlight for 3-4 hours daily.

When the seeds germinate, they begin to harden, removing the film, first for a few minutes, and then increasing the hardening time to an hour or more. It is advisable to move the plants to sunlight and carefully monitor the moisture content of the soil. Weak sprouts are best removed, this will make it possible to grow only strong and viable plants.
