Necessary Of Anti Insect Netting In Greenhouses, Anti Control, Disease Prevention, Temperature Regulation, Soil Temperature And Humidity, Shading

It is very necessary to install an insect net in a greenhouse, there are four main functions:

1) Can effectively prevent insects:

After covering the insect nets, it can basically eliminate a variety of pests such as cabbage caterpillar, diamondback moth, and aphid.

After the agricultural products cover the insect-repellent net, it can effectively eliminate many pests such as cabbage caterpillar, diamondback moth, cabbage moth, Spodoptera litura, yellow-curved beetle, locust leafhopper and aphid.

According to the test, the insect nets has a control effect of 94-97% on cabbage cabbage, diamondback moth, cowpea pod, and Liriomyza sativa, and 90% control effect on aphids.

2) Can prevent disease:

The spread of the virus will have disastrous consequences for the greenhouse cultivation, especially the locust poisoning. However, after installing the insect-proof net in the greenhouse, the pest-to-poison route was cut off, which greatly reduced the incidence of viral diseases, and the control effect was about 80%.

3) Adjust temperature, soil temperature and humidity:

In the hot season, the greenhouse was covered with a white insect net. The test showed that in the hot July-August, in the 25-mesh white insect net, the morning and evening temperatures were the same as the open, while the sunny noon was about 1 °C lower than the open ground.

In the early spring of March-April, the insect-proof net covered the shed is 1-2 °C higher than the exposed ground, and the 5 cm ground temperature is 0.5-1 °C higher than the open ground, which can effectively prevent frost.

In addition, the insect net can block part of the rainwater from falling into the shed, reduce the humidity in the field, reduce the incidence, and reduce the amount of water evaporation in the greenhouse.

4) Using insect netting with the shading effect:

In summer, the light intensity is large, and strong light will inhibit the vegetative growth of vegetables, especially leafy vegetables, while the insect net can play a certain shading effect. The 20-22 mesh silver-gray insect net has a general shading rate of 20-25%.
