How to build a greenhouse

SHARE WITH FRIENDS:

A greenhouse is a structure that creates an artificial environment (temperature, light, humidity, etc.) for crops in adverse climates. It is mainly used for growing off-season crops, seedlings for greenhouses and open fields. I. is wrapped in glass or polymer film, fiberglass, etc. It is made of wood or metal, such as iron, steel, and aluminum. There are different types of I. s. They are winter and spring, depending on the duration and duration of use; by function - where seedlings are grown and vegetables are grown; depending on the technology of growing vegetables - soil and hydroponic; Depending on the internal equipment, it is divided into root and soil types. In terms of design solutions, I.s are divided into single, double, and multi-sided types, depending on the amount of light-transmitting slopes. In Uzbekistan, mainly tomatoes, cucumbers, berries, vegetable seedlings, as well as lemons and ornamental plants are grown in I. Medium and short summer pants. In the regions, various vegetable and other crops are grown and harvested throughout the year, and new varieties and hybrids of plants are grown and other dog work is carried out. Winter I.s are intended for year-round use, where seedlings are grown for growing vegetables in spring greenhouses, greenhouses, heated yards. It is made of metal or reinforced concrete. Spring I.s are built from lightweight structures so that vegetables can be grown on the ground. It is heated by biological heat or sunlight. For perfect use of sunlight, a sloping roof I. (slope 33-45 °) jan. and two and more ni-shabs (29-33 °) to the east and west. In terms of shape, it is also divided into several types, such as lantern, hangar, block, and stalk. In I., the plant can be grown in soil (geoponics) or in soilless (or hydropic) environment. In soil I., vegetables are grown directly in the soil and are heated from the ground, biologically or technically, or not heated at all. Plants are easy to handle and care for.

Hydropon I.s are designed for growing vegetables without soil. They are equipped with waterproof rods mounted on the floor of the greenhouse or raised to a height of 70-80 cm. The inside of the pods is filled with a neutral substrate (gravel, sand, expanded clay, etc.). With the help of automatic devices, a nutrient solution is sent to the roots, which provides the plants with convenient nutrition and drinking water. In such I. all processes are automated.

Small, lightweight film-covered I.s, covered with a film, are of great importance for use in the spring. The lightness and flexibility properties of films are fully used in the construction of air-supported or blown I. In the following years, in most countries, mainly block I.s were built. Modern greenhouses have been built on an industrial basis and have become real year-round vegetable farms
