Introduction of Vegetable Greenhouse Planting Technology

1, vegetable greenhouse planting skills: leveling the land; The first step of vegetable cultivation in greenhouse is to level the land. It is necessary to renovate and weed the land, and at the same time, some base fertilizers can be added to the soil according to the vegetables planted. Fertilizer should not be too thick, otherwise it will lead to soil hardening and other deterioration phenomena.

2. Reasonable scaffolding: The span of greenhouse should not be too large, generally not exceeding 12m and the length not exceeding 120m. It is best to have earth walls on three sides to keep warm better. At the same time, it can play a better supporting role to choose a suitable steel mullion. Choosing a non-dripping film to cover the shed surface can improve the internal temperature.

3. Selection of vegetables: Due to the characteristics of the greenhouse itself, the selection of vegetables should meet the requirements: the requirements for light are low, and the lighting time in winter itself is not long, and the cover of the greenhouse will reduce the sunshine, so you must choose shade-tolerant vegetables. Strong resistance, greenhouse ventilation capacity is average, so plants must have disease resistance. Resistant to high humidity, the humidity in greenhouses is often high and difficult to control, so vegetables must be resistant to high humidity.

4. Temperature control: One of the advantages of greenhouse is its good thermal insulation, which provides a growing environment for some vegetables. However, the temperature should not be too high, and should be controlled below 33℃. If it is higher than this temperature, it should be cooled immediately, and the shed can be opened for ventilation.

5. Drip irrigation: Due to the high humidity in the greenhouse, it is not appropriate to water more, and drip irrigation is generally better. Drip irrigation itself can also save water, which is an economical and good method.
