1. According to the climate of our country, when the rainy season ends in mid-late June, the greenhouse shade net covering can be carried out. Generally speaking, the period from July to mid-September is the main covering period. During this period, in case of long-term rain, the shade net should be temporarily rolled up in the shed to enhance the light.
2. Covering the border area before seeding and emergence does not need to uncover the net, but attention must be paid to uncovering the net in the evening after seedling emergence. Floating coverage can also be carried out from transplanting seedlings to living trees, but the management of day-cover and night-uncovering should be carried out.
3. After seedling emergence and planting survival, shelf covering should be carried out.
4. Early spring melon, eggplant and legume vegetable can be covered with frost-proof after planting. It can be covered on the small arch shed or the small arch shed in the shed. If the shading net is covered on the thin film arch shed, the frost-proof effect is better, but the management of day-to-night cover should be carried out.
5. Summer coverage should be based on climate and vegetable varieties, growth conditions, timely access to the Internet, uncovering the net, if in cloudy and rainy days, in sunny days, sooner or later, the net can also be uncovered, the temperature above 30 degrees generally from 9 a.m. to 4 p.m.
6. Cover in the evening in winter, cover in the evening and when the cold current comes, and uncover in the daytime.
