Cultivation techniques of vegetables in greenhouse

Greenhouse vegetable cultivation technology is a commonly used planting technology, because it has a good heat preservation effect, can grow out-of-season vegetables, so what is the greenhouse vegetable cultivation technology?

1. Basic introduction of vegetable cultivation techniques in greenhouse

The greenhouse was originally a special equipment for vegetable production, but with the development of production, the greenhouse has been used more and more widely. At present, the greenhouse has been used for potted and cut flower cultivation; fruit production is used for the cultivation of grapes, strawberries, watermelons, melons, peaches and oranges; forestry production is used for forest seedling cultivation, ornamental tree cultivation, etc.; aquaculture is used for sericulture, chicken, cattle, pig, fish and fish fry.

Greenhouse construction needs to choose sunny, wind shelter, high dryness, good drainage, no soil infectious diseases to build the shed.

When buckling the film to the greenhouse, it is necessary to avoid film damage, especially if it is a bamboo shed. Before buckling the film, the protruding part of the surface of the shelf should be flattened or wrapped with old cloth, and then fixed with a spring, a layer of old newspaper should be added to the slot.

II. Cultivation techniques of vegetables in greenhouse

Greenhouse vegetables need reasonable watering, fertilization and ensuring sufficient light, because different vegetables have different requirements for water, fertility and light, so the requirements of the types of vegetables planted should prevail.

For example:

The precocious cultivation of eggplant and melon vegetables is the most common project in greenhouse. Open-field cultivation is generally planted from late March to mid-April and harvested from early May to July. Cultivation in greenhouse can be planted in advance from January to March and harvested from late March to July. Early listing, higher yield, longer flowering and fruiting period, but also according to market needs, early sowing amaranth, agaric, hollow vegetables and other warm green leafy vegetables can also be put on the market earlier.

Tomatoes generally have 4 beds in a greenhouse, 1.5 meters in strip trench and planted in two rows. The row spacing of planting is about 75 cm, the plant spacing is 20m ~ 30cm, the eggplant spacing is 40cm ~ 50cm, and 2000 ~ 2400 plants are planted per mu.

In addition, it is necessary to carry out field management such as temperature, fertilizer and water, frame pruning and so on, so that vegetables can be picked when they are ripe.
