Vegetable insect net coverage cultivation is one of the important measures for pollution-free production of agricultural products. It is of great significance to produce vegetables with no pesticide residues, no pollution, and no pollution without or with minimal use of chemical pesticides, and has become an emerging model for vegetable cultivation, especially for leafy vegetables.
Agricultural vegetable insect prevention net is a new type of agricultural covering material made from polyethylene as raw material, with additives such as anti-aging and UV resistance added. It is formed by drawing and weaving, resembling a window screen, with a mesh size of 30-40 mesh. It has the characteristics of heat resistance, high tensile strength, UV resistance, stain resistance, corrosion resistance, anti-aging, non-toxic and odorless. It is mainly used to cover the ventilation openings of plastic arches and greenhouses, cutting off the pathways for various pests and adults to infiltrate, reproduce, harm larvae, and transmit viruses, achieving pesticide free cultivation of vegetables.
This is an extremely popular new environmental protection technology for urban residents who frequently suffer from poisoning due to excessive pesticide residues in their food. In short, vegetable insect prevention nets are artificial isolation barriers constructed with insect prevention nets, which repel pests from the net and achieve the effect of pest control and vegetable protection.
