What Are the Functions of the Anti-insect Net for Agriculture in Greenhouse ?

Author:

It is necessary to install anti-insect nets for agriculture in greenhouses, what are the benefits? Let's take a look.

Effective control of pests

After being covered by anti-insect net for agriculture, various pests such as the diamondback moth and aphids can be basically eliminated. Agricultural products covered with anti-insect nets for agriculture can effectively prevent damage caused by pests such as diamondback moth, cabbage looper, cabbage moth, fall armyworm, yellow striped flea beetle, monkey leaf insect, and aphids.

According to experiments, the control effects of anti-insect net for agriculture on diamondback moths, cabbage loopers, pod borers, and Bactrocera latifrons are 94-97%, and the control effect on aphids is 90%.

Prevent virus diseases

Virus transmission can bring catastrophic consequences to greenhouse planting, especially when aphids are the vectors. However, after installing anti-insect nets for agriculture in greenhouses, the transmission route of pests is cut off, greatly reducing the incidence of virus diseases, with a control effect of about 80%.

Regulate temperature, soil temperature, and humidity

In the hot season, covering the greenhouse with white anti-insect nets for agriculture, experiments show that in the hot months of July and August, the morning and evening temperatures are the same as outdoor temperatures in 25 mesh white insect nets, while on sunny days, the midday temperature is about 1℃ lower than outdoor temperature. In early spring (March-April), the temperature inside the covered greenhouse is 1-2℃ higher than outdoor temperature, and the soil temperature at 5cm below the surface is 0.5-1℃ higher than outdoor temperature, which can effectively prevent frost damage.

In addition, anti-insect net for agriculture can block some rainwater from entering the greenhouse, reduce field humidity, reduce disease incidence, and reduce evaporation of water in the greenhouse on sunny days.

Has shading effect

In summer, the intensity of sunlight is high, which will inhibit the growth of vegetable nutrients, especially leafy vegetables. Agricultural insect nets can play a certain shading role. The shading rate of 20-22 mesh silver-gray insect nets is generally 20%-25%.

Prevent fruit drop

The fruit ripening period is in summer, and there are often heavy rainfalls. If insect nets are used for covering, it can reduce the fruit drop caused by heavy rain in the ripening period, especially for fruits such as dragon fruit, blueberry, and bayberry.

Prevent frost damage

The young fruit period of fruit trees and the fruit ripening period are in the cold season, which is prone to cold damage. Using insect nets for covering is not only conducive to improving the temperature and humidity inside the net, but also prevents frost damage to the fruit surface by isolating it. It has a very significant effect on preventing frost damage to loquat during the young fruit period and cold damage to citrus fruit during the ripening period.
