How to choose insect net?

In agricultural production, insect nets can not only prevent pests from entering the shed but also regulate air temperature, soil temperature, and humidity. What should we pay attention to when using the greenhouse insect net? How can we make the insect net play a good role?

In the selection of insect nets for greenhouses, the mesh number, color, and width of the gauze should be considered. If the mesh is too small and the mesh is too large, it will not achieve the desired insect-proof effect; if the mesh is too large, the mesh is too small, although it can prevent insects, the ventilation is poor, resulting in high temperature and excessive shading, which is not conducive to Crops grow. For those with many weeds and whiteflies outside the shed, it is necessary to prevent them from entering through the holes of the insect-proof net according to the smaller size of the whiteflies. It is recommended that vegetable farmers use denser insect-proof nets, such as 40 mesh to 60 mesh.

In spring and autumn, the temperature is low and the light is weak, so white insect-proof nets should be used. In summer, in order to take into account the shading and cooling, it is advisable to use black or silver-gray insect-proof nets. In areas where aphids and virus diseases occur seriously, in order to repel aphids and prevent virus diseases, silver-gray insect control nets should be used.

When choosing an insect net, it is also necessary to check whether the insect net is complete. Some vegetable farmers report that many newly purchased insect-proof nets have holes, so they remind vegetable farmers that they should unfold the insect-proof nets when purchasing to check whether they insect-proof nets are in good condition.
