It is necessary to install insect-proof nets in greenhouses. It can play four roles:

1. Effective against insects. After covering the insect control net, basically can avoid a variety of insect pests such as cabbage bug, diamondback moth, aphid.

Agricultural products covered with insect control net can effectively eliminate the cabbage insect, diamondback moth, cabbage night moth, twill night moth, yellow beetle, ape leaf insect, aphid and other pests. According to the test, insect nets of cabbage caterpillar, patella xylostella, cowpea moth, America spot hidden fly control effect for 94-97%, for aphid control effect of 90%.

2. Prevent disease. The spread of the virus can have catastrophic consequences for greenhouse cultivation, especially the transmission of aphids. However, after the insect net is installed in the greenhouse, the transmission path of the pest is cut off, which greatly reduces the incidence of viral diseases, and the prevention effect is about 80%.

3. Adjust the air temperature, soil temperature, and humidity. In the hot season, cover the greenhouse with white insect nets. Tests show that in hot July to August, the temperature of morning and evening in the 25-mesh white insect nets is the same as that of the open field, and it is about 1°C lower than the open field at noon on a sunny day. In early spring from March to April, the temperature in the insect-proof net covered shed is 1-2 ° C higher than the open field, and the 5cm ground temperature is 0.5-1 ° C higher than the open field, which can effectively prevent frost. In addition, the insect-proof net can block some rainwater from falling into the shed, reduce field humidity, reduce the incidence, and reduce water evaporation in the greenhouse on sunny days.

4. Light-shielding effect. Summer light intensity is strong, strong light will inhibit the vegetative growth of vegetables, especially leafy vegetables, and insect nets can play a certain light-shielding effect. The general shading rate of 20-22 mesh silver-gray insect-proof nets is 20-25%.
