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, which significantly increases the relative humidity of the air. At noon, the maximum value of humidity increases, generally reaching 13-17%, and the humidity is high. Reduced soil evaporation increases soil moisture.
The sunshade net is made of polyethylene (HDPE), high-density polyethylene, PE, PB, PVC, recycled materials, new materials, polyethylene, etc. as raw materials. After being stabilized by ultraviolet rays and anti-oxidation, it has strong tensile strength Anti-aging, corrosion resistance, radiation resistance, light weight and so on. It is mainly used for the protective cultivation of crops such as vegetables, fragrant aunts, flowers, edible fungi, seedlings, medicinal materials, ginseng, and ganoderma, as well as aquatic poultry farming, etc., which has obvious effects on increasing yield.
