The insect proof net of the shed is a new type of agricultural covering material after the agricultural film and sunshade net. It is also one of the important accessories of the steel frame and the shed. It is made of high-quality high-density polyethylene (HDPE) with anti-aging, anti ultraviolet and other chemical additives. It is woven by drawing. It looks like a window screen. It has the characteristics of high tensile strength, heat resistance, water resistance, corrosion resistance, non-toxic and tasteless Color.
Vegetable insect control net is a kind of artificial isolation barrier constructed by insect control net, which can keep pests out of the net, and then receive the function of insect control and vegetable preservation. With this skill, the use of chemical pesticides can be greatly reduced. At present, the technology of covering vegetable insect net has been widely used in summer and autumn vegetable production in prosperous countries and regions, which is the key technology to produce green and pollution-free vegetables. In China, agricultural research institutions have also begun to choose insect net covering skills, and achieved remarkable results.
Agricultural insect screen is a net fabric made of high-density polyethylene as the main material and added with anti-aging agent, anti ultraviolet and other chemical additives. It has the advantages of non-toxic, tasteless, heat-resistant, water-resistant, corrosion-resistant, aging resistant, UV resistant and strong tensile resistance. It has the function of ventilation, light transmission and heat dissipation, but insects can not enter. It is easy to use and keep The service life can reach 3-5 years.
The insect proof net in the shed not only has the function of insect prevention, but also has the functions of blocking the strong light, storm erosion and hail attack. The experiment shows that the mesh number of the net is too small and the effect of the net is decreased in summer and autumn. The net with 30-60 mesh is more ideal.
