Do you know the three precautions before and after the insect screen coverage? Follow the editor of Cheapest Black Coated Insect Screen products to have a simple look!
1. The selection of greenhouse insect-proof nets should consider the number of meshes, mesh color and mesh width. If the mesh number is too small and the mesh is too large, it will not have the effect of insect control; if the mesh number is too small, it can prevent insects, but poor ventilation will cause high temperature and excessive shading, which is not conducive to crop growth. Generally use 22-24 mesh mosquito nets. Compared with summer, spring and autumn have lower temperatures and weaker sunlight. White insect nets should be used; in summer, black or silver-gray insect nets should be selected to consider shading and cooling; in areas where aphids and virus diseases are serious, Silver-gray insect-proof nets should be used to repel aphids and prevent viral diseases.

2. In order to ensure the quality of coverage, the anti-insect net should be fully enclosed, tightly covered with soil, and firmly fixed with a laminated thread; the doors of large and medium-sized greenhouses and greenhouses need to be installed with anti-insect nets, and be careful to close them immediately when entering and exiting. The height of the trellis should be significantly higher than the height of the crops in the arched shed to prevent pests from eating or laying eggs on the plant leaves. There must be no gap between the insect screen used to seal the vent and the transparent cover, so as not to leave a passage for pests. Check and repair the holes and gaps of the insect screen at any time.
3. Seeds, soil, plastic greenhouses or greenhouse frameworks and frame materials may contain insect eggs. Before vegetable planting, the treatment of seeds, soil, scaffolding frame and frame material with insect-proof net is a key link to ensure the effect of insect-proof net covering cultivation.
