The first step in greenhouse vegetable planting is to level the land. The land should be renovated and weeded, and some bottom fertilizer can also be added to the soil according to the vegetables to be planted. The fertilizer should not be too strong, or it will lead to soil hardening and other deterioration phenomena.

The span of the greenhouse should not be too big, usually not more than 12 meters and not more than 120 meters in length. It is best to have earth walls on three sides for better insulation. At the same time to choose the right steel uprights, which can play a better supporting role. Choose a drip-free film to cover the surface of the shed, which can increase the temperature inside.

The greenhouse vegetable planting technology is a relatively common technology, which has better heat preservation performance, it is loved by people, because at any time you can eat vegetables in the opposite season. In general, greenhouse vegetables are used bamboo and steel-based structure skeleton, and then covered with one or more layers of thermal insulation plastic film, so that a simple structure to create a complete greenhouse space.

Covering the greenhouse with mulch or adding a small arch. Covering the film can make the surface soil temperature increase by 2 ℃, additional small arch can make the temperature of the vegetable growing environment to maintain above 15 ℃.

Fertilizer management. Fasten the film before watering the bottom of the water, generally the first two leeks do not water, just after harvesting 4-6 days after the wound healing, combined with fertilizer watering 1 time, each time per mu with 10 kg of urea to 1500 kg of water watering. Pest control. Greenhouse leeks during the growth period, due to high humidity in the shed, prone to gray mold.

Time to grasp, greenhouse planting vegetables are mainly planted some anti-seasonal vegetables, and depends largely on the planting time of the morning and evening, taking into account the spring around the time of the highest benefits, we should plant in the spring should be centered on yield. Specific operation schedule, if it is a yearly crop, we should set the planting period in the middle of the first half of October. If it is two crops a year, the first crop should be in early July, the second crop in December to the next year in January customized, this planting time benefit is very good.
