1 temperature management In order to promote the easing of seedlings in the spring, 5-7 fields are generally drowsy after planting, and when the temperature in the shed exceeds 35 degrees, the larvae are released, so as to increase the temperature in the shed, promote early rooting of the seedlings, and early seedling easing. With multi-layer film covering, the insulation curtain (second curtain) should be opened during the day to facilitate light transmission and increase the temperature of the ground. Cover and keep warm again in the evening. After about a week, the leaves of the seedlings turn green, and the heart leaves begin to grow. The seedlings can be poured with water, and they begin to gradually release after tax. In sunny days, the weather is maintained at 25-2 degrees, and maintained at 17 degrees or more during the night. After mid-April, when the temperature of the shed increases to 25 degrees or more, Xiao Xiaofeng should be carried out. Afterwards, with the increase of the outside temperature, the outlet is gradually expanded. When the air is released, the shed film is opened from the back, and windy weather should always pay attention to the air outlet management, and the wind direction changes, and the air outlet is changed to the leeward surface. When the shelf temperature drops to 20 degrees, the air outlet gradually closes. With multi-layer coverage, it is no longer possible to close the air outlet at night to allow day and night ventilation. 2 Water and fertilizer management Planting water can be cultivated 2-3 days after the planting, in order to raise the temperature, dare to delete the soil ventilation, and promote the slow seedlings. About one week after planting, the seedlings were irrigated, and then they were transplanted into tillage seedlings. After most of the plants were planted with peppers (if there were walnuts), the seedlings were finished and watering was started. Afterwards, the soil in the greenhouse is often kept moist. Generally, the water is poured in about 7 days. After the result is flooded, 0.1 to 0.2% of monopotassium phosphate and 100.1 urea can be sprayed once a week. To cultivate soil and cultivate soil should not be too early, otherwise it is easy to make the root in a relatively deep soil layer, the ground temperature rises slowly, and the root develops leaves slowly, which affects the growth of the above ground.
