Although culture and unpretentious, but the cultivation of lettuce - hard work. It requires not only physical effort, but also good knowledge, which will help provide proper care.
Growing lettuce in a greenhouse is carried out in two ways:
- on the ground;
- in hydroponics.
In the small greenhouses of private estates practiced ground cultivation of leaf lettuce. The culture is sown in early spring. In winter, this method of planting is not possible, since at the slightest frost the soil freezes. You can grow lettuce in boxes or pots, but you need to monitor the level of humidity of the earth and constantly irrigate the planting.
In large farms, the method of growing lettuce hydroponically is used. This means that the roots of plants are immersed in a special environment enriched with minerals and other beneficial substances. The exact proportion of trace elements depends on the type of salad.
How to grow watercress? Growing watercress practiced on vermiculite. A layer of substance is poured into the tray, on top - river sand to hold the fertilizer. After that, fill the tray with water.
Growing watercress has gained wide popularity. Each bush is placed in small piles without a bottom. The upper edges of the pile are held by the flooring. When it is put on the pallet, the roots of the plants are in the water. Water is periodically drained, replacing fresh.
When solving the issue of growing lettuce in hydroponics, it is better to choose the most advanced method of planting - flow hydroponics.
Each bush is placed in gutters, where water circulates from the nutrient reservoir to planting and back. There is no need to constantly disturb delicate plants, then raising, then lowering the tray to replace the water.
The amount of fertilizer, the supply of fresh solution and its temperature is controlled and carried out automatically. The cost of electronics quickly pays off, as it is easy to grow lettuce in a greenhouse in winter.
Growing crops in greenhouses all year round is divided into 2 periods:
- in September - December;
- in January - April.
At the beginning of each season, lettuce seeds are spread in small containers on wet peat, covered with foil and placed in a special chamber with bright lighting. After 3 days, when sprouts appear, the plants are planted in pots with wet soil for growing seedlings. At the same time, the temperature should not exceed 20 ° С, since the culture does not like heat and grows poorly at higher temperature indices.
When the lettuce leaves develop, after about 2 weeks, the seedlings are placed in gutters on hydroponics. After 2-3 weeks, when the lettuce grows in the greenhouse, the planting is removed. Growing lettuce in greenhouses is carried out under certain conditions. When germinating seeds and growing seedlings culture should provide maximum coverage.
For germination of seeds need absolute moisture content of the soil and the temperature is not higher than 10-18 ° C. For growing seedlings humidity may be less, but the permissible temperature is not higher than 18 - 20 ° C.
Growing lettuce from seedlings requires high humidity if planting is ground. Allowable temperature - up to 23 ° C. At higher temperatures, the plant begins to throw out arrows and bloom. Illumination is allowed moderate, since the landing is already strong and develops well, even with some shading.
To grow this garden crop in a greenhouse, flow hydroponics is the most effective method. If the air temperature suddenly became higher than 25 ° С, it is possible to cool the plantings by running a cooled solution not higher than 10 ° С along the gutters. Plants will not freeze and will not begin to bloom.
