Use and classification of sunshade net.

The use of sunshade net

Sunshade nets are mainly used in summer, especially in the south. Some people describe: the northern winter is a piece of white (film coverage), the southern summer is a piece of black (covering the sunshade net). In summer, vegetable cultivation with sunshade nets has become a major technical measure for disaster prevention and protection in South China. The northern application is also limited to summer vegetable seedling. In summer (June - August), the main function of covering the sunshade net is to prevent the exposure of the sun, prevent the impact of heavy rain, the harm of high temperature, and the spread of diseases and pests, especially to prevent the migration of pests.

After covering in summer, it plays a role of blocking light, blocking rain, moisturizing and cooling. After winter and spring covering, there is a certain heat preservation and humidification effect.

Moisturizing principle: After covering the sunshade net, because of the cooling and windproof effect, the communication speed between the air and the outside world in the cover area is reduced, and the relative humidity of the air is significantly increased. At noon, the humidity increase is the largest, generally reaching 13-17%, the humidity is high, the soil evaporation decreases, and the soil moisture is increased.

Sunshade net is made of polyethylene (HDPE), high-density polyethylene, PE, PB, PVC, recycled material, new material, polyethylene propylene and other raw materials, after ultraviolet stabilizer and anti-oxidation treatment, with strong tensile resistance, aging resistance, corrosion resistance, radiation resistance, light and other characteristics. Mainly used in vegetables, fragrant plants, flowers, edible fungi, seedlings, medicinal materials, ginseng, ganoderma lucidum and other crops protective cultivation and aquatic poultry industry, to improve the yield and so on have obvious effect.

Sunshade net classification

1. Round silk sunshade net

Because the sunshade net is interwoven by warp and weft, mainly by warp knitting machine, so if the warp and weft are woven by round wire, it is round wire sunshade net.

2. Flat silk sunshade net

The warp and weft lines are flat silk woven sunshade net is flat silk sunshade net, this net is generally low gram weight, high sunshade rate, mainly used in agriculture, garden sunshade and sunscreen.

3. Round flat wire sunshade net

The warp is flat wire, and the weft is round wire, or the warp is round wire, and the weft is flat wire, and the sunshade woven net is a round flat wire sunshade net.
