Shade nets are mainly used in summer, especially in the south where the promotion area is large. Some people describe it as: the northern winter is a piece of white (film cover), and the southern summer is a piece of black (covered with a shading net).

Northern applications are also limited to summer vegetable seedlings. In summer (June-August), the main function of covering the sunshade net is to prevent the scorching sun, the impact of heavy rain, the harm of high temperature, and the spread of pests and diseases, especially to prevent the migration of pests. After covering in summer, it plays a role of blocking light, rain, moisturizing and cooling; after covering in winter and spring, it also has a certain effect of heat preservation and humidification.

Moisturizing principle: After covering the sunshade net, because of the cooling and windproof effect, the communication speed between the air in the covered area and the outside world is reduced, and the relative humidity of the air is further increased.

At noon, the humidity increase value is larger, generally reaching 13-17%, and the humidity is high soil evaporation decreased and soil moisture increased. Shade nets are mainly used in the protection and cultivation of vegetables, fragrant buds, flowers, edible fungi, seedlings, medicinal materials, ginseng, Ganoderma lucidum and other crops, as well as in aquatic and poultry breeding industries, and have obvious effects on increasing production.
