Where and how to use the sun shade net Jun 23
Shading nets are mainly used in summer, especially in the South where they are widely promoted. Some people describe it as white in winter in the north (covered by the film), and black in summer in the south (covered with shading nets). The use of sunshade 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-August), the main function of covering the sunshade net is to prevent the scorching sun, the impact of heavy rain, the hazard of high temperature, the spread of pests, and especially play a good role in preventing the migration of pests.

After covering in summer, it plays a role of blocking light, raining, moisturizing, and cooling; after covering in winter and spring, it also has a certain function 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 obviously further increased. At noon, the humidity increase value is the largest, generally reaching 13-17%, and the humidity is high. The amount of soil evaporation decreases, increasing the 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, It has the characteristics of aging resistance, corrosion resistance, radiation resistance and lightweight. It is mainly used for the protective cultivation of vegetables, Xianggu, flowers, edible fungi, seedlings, medicinal materials, ginseng, Ganoderma lucidum and other crops and aquatic and poultry breeding industry, etc., and has obvious effects on increasing output.
