1 Standard Shed Type: The span of the shelf body should reach 6 to 12 meters. The dripless longevity film should be used. Conditional special colored film should be selected for the cultivated species. Coverage should not be less than three membranes (three layers of agricultural film covering) plus two curtains (two layers of straw curtain covering). It is best to use four membranes plus three curtains to cover, and it is the safest for winter.
2 Increase the temperature of the greenhouse: Uncover the mulching film inside the large row, then deep-row large rows, cover with 10 cm thick dry wheat grass, or fill in wheat stubble or wheat straw (grass) while deep-graining, or put the dried cows and horses Dung on the surface, about 10 cm in thickness, and finally cover the film. Irrigation should use large and small watering in turn. First pour small rows 7 to 10 days before pouring large rows.
3 Fertilizer and Water Management: Vegetables in winter and spring sheds are most likely to enter the flowering stage and the initial stage (or the result period). If the weather is hot and dry, it must be watered in time; when it encounters continuous rain, it is necessary to clear the ditch in time to eliminate water accumulation. Do not flood. When the first ear fruit has been seated and begins to inflate, the compound fertilizer is topdressed once, and Mushi 10 to 15 kg. The flowering result will be followed by 1 to 2 compound fertilizers each time, each applying 15 to 20 kg. In order to prolong the capping period of peppers and prevent premature aging, it is necessary to use 0.3% potassium dihydrogen phosphate and 0.3% urea for foliar spraying according to the growing situation to supplement the nutrition.
