Planting techniques of vegetables in greenhouse

The structure of greenhouse generally adopts steel, wood and bamboo, which has good seismic and wind resistance; Cultivation modes are generally divided into spring cultivation and autumn and winter cultivation. Vegetables cannot be ventilated immediately after planting, which will increase the temperature in the greenhouse. Choosing different shading nets according to different seasons is beneficial to the growth of seedlings.

1, scaffolding structure

There are many scaffolding structures in greenhouse vegetable planting technology. At present, steel, wood and bamboo scaffolding structures are widely used, both of which have good seismic performance and can protect vegetables in greenhouses when strong winds blow.

2. Cultivation mode

In greenhouse, it is generally divided into spring cultivation and autumn and winter cultivation, and can also be cultivated according to market demand; The cultivation time of early maturity in spring is generally from February to April, and the planting time is around May. The planting time of delayed cultivation in autumn and winter is generally 65438+1October and165438+1early October.

3. Tian Tuan management

When planting vegetables, they can't be ventilated immediately and need to be closed for a week, especially tomatoes, Chinese cabbage and other crops. It is necessary to raise the temperature in the greenhouse, which is more conducive to the growth of seedlings. During the growing period, vegetables need to be watered once a day and fertilized once every three days. Fertilizers can be farmyard manure with balanced nutrition.

4. Strong sunshade coverage in summer. It is necessary to choose the most suitable sunshade net according to the variety and scale of growing vegetables. Short-term crops generally choose black sunshade net; In winter, the light is not strong, but the seedlings in the greenhouse may get sunburned, so it is necessary to prepare a white sunshade net.
