Cultivation techniques of vegetables in greenhouse

The emergence of greenhouse makes out-of-season vegetables possible, and it is also loved by farmers because of its good thermal insulation performance. Then the editor will introduce to you the techniques of vegetable cultivation in the greenhouse and the prospects of vegetable cultivation in the greenhouse.

I. vegetable cultivation techniques in greenhouse

1. Formation of land

The first step in growing vegetables in a greenhouse is to level the land. The land should be renovated and weeded, and some base fertilizer 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 deteriorating phenomena.

2. Set up the shed reasonably

The span of the greenhouse should not be too large, generally no more than 12 meters, the length does not exceed 120 meters. It is better to have earthen walls on all three sides for better heat preservation. At the same time, we should choose a suitable steel frame, which can play a better supporting role. Choose no drip film to cover the shed surface, which can increase the internal temperature.

3. Vegetable selection

Due to the characteristics of the greenhouse itself, the selection of vegetables should meet several key points. First, the lighting requirements are low, the winter itself is not long, coupled with the greenhouse cover will reduce the entry of sunlight, so we must choose shade-tolerant vegetables. The second is strong resistance, the ventilation capacity of the greenhouse is general, so the plant must have the ability to resist disease. The third is to withstand high humidity, the humidity in the greenhouse is often very high, and it is difficult to control, so vegetables must be resistant to high humidity.

4. Adjust the temperature

One of the advantages of the greenhouse is its good heat preservation, which can provide a growing environment for some vegetables. But the temperature should not be too high, it should be controlled below 33 ℃, and it should be cooled immediately after it is higher than this temperature, and the shed can be opened for ventilation.

5. Drip irrigation

As the humidity of the greenhouse is higher, so watering should not be much, generally using drip irrigation is better. Drip irrigation itself can also save water, which is a good and economical way.

II. Prospect of vegetable cultivation in greenhouse

The prospect of growing vegetables in the greenhouse is very considerable. With the pursuit of healthy food, the demand for vegetables has increased sharply in the last two years. Many vegetables are grown according to the normal season, which can not meet the current market demand. At this time, it reflects the anti-seasonal advantage of greenhouse vegetables. Nowadays, greenhouse vegetables are becoming more and more popular, and the market demand is gradually increasing.
