The shade net is a newest type of special protective covering material for agriculture, fishery, animal husbandry, windbreak, and soil covering. After being covered in summer, it plays a role of blocking light, raining, moisturizing and cooling. After being covered in winter and spring, it also has a certain effect of heat preservation and humidification. 

Generally, the leafy vegetables grown in winter and spring directly cover the surface of the leafy vegetables with a shading net to prevent low temperature hazards. Because of its light weight, only tens of grams per square meter, it will not affect the grown tall leafy vegetables. Overwhelm, bend, and reduce the commodity. And because it has a certain degree of air permeability, the surface of the leaves is still dry after being covered, which reduces the occurrence of diseases. It also has a certain degree of light transmittance, and will not "cover the yellow and cover the rotten" after being covered.


Main purpose: 

Nowadays, the shade nets are widely used as special protective covering materials for agriculture, fishery, animal husbandry, windbreak, and soil covering. The use of shade nets to cultivate vegetables in summer has become a major technical measure for disaster prevention and protection. The main function of the shading net is to prevent the scorching sun, the impact of heavy rain, the hazard of high temperature, and the spread of pests and diseases, especially to prevent the migration of pests. After the summer is covered, it plays a role of blocking light, raining, moisturizing and cooling; more and more farmers have discovered the effect of shade nets in winter heat preservation and humidification. The planting customers of our factory have obvious increase in production after winter coverage. It is recommended that farmers buy and try .


Moisturizing principle: 

After covering the shading 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 improved. At noon, the humidity increase value is the largest, generally increasing by 13-17%, and the humidity is high. The amount of soil evaporation decreases, increasing the soil moisture.

The shade 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 light weight. It is mainly used for the protective cultivation of vegetables, Xianggu, flowers, edible fungi, seedlings, medicinal materials, ginseng, Ganoderma lucidum, Panax notoginseng, blueberries and other crops and aquatic poultry farming, etc. It has obvious effects on increasing production.

Flat wire shade net: 

The shade net woven by both warp and weft threads is flat wire shade net. This kind of net is generally low in weight and high in shading rate. It is mainly used for agriculture, garden shading and sun protection. This type of application is the most widely used, and our factory produces a large number of flat wire shade nets all the year round.

Round flat wire shade net:

 the warp thread is flat wire, the weft thread is round wire, or the warp thread is round wire and the weft thread is flat wire, the shading woven net is round flat wire shade net.
