After covering the sunshade net, because of the effect of cooling and windbreak, the communication speed between the air and the outside world in the covering area is reduced, and the relative humidity of the air is further increased obviously. At noon, the increase value of the humidity is the largest, generally reaching 13-17%. With high humidity, the evaporation of the soil is decreased, and the soil humidity is increased.
The sun shade net is made of HDPE, PE, recycled material, new material as raw materials. After UV stabilizer and anti-oxidation treatment, it has the characteristics of strong tensile resistance, aging resistance, corrosion resistance, radiation resistance and portability. It is mainly used for the protective cultivation of vegetables, flowers, edible fungi, seedlings, medicinal materials, ginseng, and other crops, as well as the aquaculture and poultry industry, and has obvious effect on improving the yield.
