The use of shade net:


Shade nets are mainly used in summer, especially in the south where the promotion area is large. Some people describe it as “white in winter in the north (film covering), and black in summer in the south (covering shade nets).” The use of shade nets to cultivate vegetables in the south in summer has become a major technical measure for disaster prevention and protection. Northern applications are also limited to summer vegetable seedlings. In summer (June to August), the main function of covering the sunshade net is to prevent the exposure of the hot 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 exchange rate between the air in the covered area and the outside world is reduced, and the relative humidity of the air is obviously increased. Soil evaporation decreased, increasing soil moisture.

The sunshade net is made of polyethylene (HDPE), high-density polyethylene, PE, PB, PVC, recycled materials, new materials, polyethylene propylene, etc. as raw materials. After UV stabilizer and anti-oxidation treatment, it has strong tensile strength, Aging resistance, corrosion resistance, radiation resistance, lightweight and other characteristics. It is mainly used in the protective 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 has obvious effects on improving production.
