The technology of cultivation of vegetables in greenhouses general. Plant growth in the greenhouse.

Protecting vegetables in the field, using plastics is an accessible method that allows obtaining or extending early vegetables vegetation in autumn vegetables.

  Microclimate conditions, which are made in shelters creates the possibility of performing in a year, on the same surface, 2-3 cultures.

  Tillage and preparing shelters

In order to pay special attention to planting tillage and preparing shelters. Tillage and preparation works executed greenhouses consist of fall and spring works executed.

The works executed fall.

The main works relate to soil preparation and providing skeletal support.

Works executed spring.

Early spring, whether ground or not dealt with greens, proceed to the drainage of areas where it stagnates.

If I did that greenhouses are filled with greens, perform the following works:

• harrowing land immediately;
• disinfection of production space;
• disinfect the soil before planting (10-15 days);
• fertilization 250-300 kg / ha of ammonium nitrate;
• 8-10 days herbicide before planting;
• polythene mounting 8-10 days before planting;
• mobilization of the ground cutter, the depth of 15-18 cm;
• shaping the layers of soil is raised;

Intensive crop rotation and the use of the land

Time using the solar year is determined by the area's natural conditions and community members and how culture practiced. For rational and efficient operation of greenhouses, in this culture system intensive practice, in addition to the basic crop cultivating two successive and one is associated.

Leading environmental factors during cultivation in greenhouses

Production increases achieved in crops protected with plastic against unprotected culture is built on the favorable microclimate conditions in shelters made of plastic. Conducting conditions of the housing with plastic is correlated to state demands time and vegetable species cultivated.

The average temperature is the main factor that contribute to the early production of bigger crops protected by plastic.

Relative humidity in greenhouses is higher than in the atmosphere and in greenhouses covered with glass. For flexible plastics (polyethylene and polyvinyl chloride) is typical of condensation on the inner surface of the film covering the solarium. Condensation and fall of the plants favor the development of fungal diseases in crops of tomatoes, pepper and eggplant.

Maintenance works of tunnels vegetable crops

To ensure all necessary conditions optimal growth and development of plants grown in greenhouses, it is necessary to perform the following works:

• daily checking the state of clamping the seedling;
• Prasit loosening the soil by repeated;
• as required irrigation water species;
• Fazi fertilization by applying complex ingrasminte;
• control of diseases and pests in the range of 8-10 days treatment;
• carnitul to hasten plant fructification and obtain quality productions;
• trellising and management of the plant, in the case cucumbers and tomatoes.
