An insect protection net is used to cover the whole growing period of pollution-free vegetables to prevent the transmission of diseases and viruses from pests, reduce the number of pesticides, and isolate pollen when making original seeds. It has the functions of light transmission, anti-storm, and anti-hail impact.
material of insect protection net
The agricultural greenhouse insert protection net is a mesh fabric made of high-density polyethylene as the main raw material and adding anti-aging agent, anti-ultraviolet, and other chemical additives, after wire drawing, with non-toxic, odorless, heat-resistant, water-resistant, It has the advantages of corrosion resistance, aging resistance, UV resistance, strong tensile strength, etc. It has the function of ventilation, light transmission, and heat dissipation, and insects cannot enter; it is easy to use and store, it can be used correctly for storage, and its service life can reach 3-5 years.
Features of insect protection net
An insect protection net is a new type of agricultural covering material after agricultural film and sunshade net. It is made of high-quality high-density polyethylene (HDPE) with chemical additives such as anti-aging and anti-ultraviolet as raw material and is woven by wire drawing. Shaped like a window screen, it has the characteristics of high tensile strength, heat resistance, water resistance, corrosion resistance, non-toxic and tasteless.
The role of insect protection net
A vegetable insert protection net is an artificial isolation barrier constructed by insert protection net, which keeps pests out of the net, to obtain the effect of insect control and vegetable protection. The application of this technology can greatly reduce the use of chemical pesticides. At present, the vegetable insect protection net covering technology has been widely used in the production of summer and autumn vegetables in developed countries and regions, and it is the key technology for the production of green and pollution-free vegetables. In China, agricultural scientific research institutions have also begun to adopt the cover technology of INSect protection net, and have achieved remarkable results.
Application scope of insect protection net
Vegetable insect protection net covering cultivation is a practical and beneficial agricultural new technology that increases yield and has been widely used in some developed countries. It is suitable for summer and autumn small green vegetables, leafy vegetables, mustard greens, melons, beans, and other crops to cover the entire growth period (can be covered with various types of scaffolding such as greenhouses, medium sheds, small arch sheds, and horizontal sheds in the field) to prevent flying insects from entering the shed Inside, cut off the breeding route of pests (adults), effectively control the spread of various pests such as cabbage caterpillars, diamondback moths, aphids, flea beetles, Spodoptera littoralis, Liriomyza americanus, Spodoptera litura, etc. and prevent the harm of virus transmission, The application of chemical pesticides in vegetable fields is greatly reduced, so that the fruits and vegetables produced are of high quality and hygienic.
Insect protection net not only has the function of preventing insects but also has the functions of blocking strong light, and resisting storm erosion and hail attack. The test shows that the number of insert protection nets covered in high-temperature seasons in summer and autumn is too small, and the insect control effect is reduced.
