Greenhouse Insect Nets shape like window screen, with tensile strength, uv resistance, heat resistance, water
resistance, corrosion resistance, aging resistance and other properties, non-toxic and tasteless, service life is
generally 4-6 years, up to 10 years.It not only has the advantage of sunshade net, but also overcomes the deficiency
of sunshade net.
It is necessary to install insect-resistant net in greenhouse. It can play four roles:
1. Effective insect control.After covering insect-control net, it can basically avoid many insect pests such as rapeseed
insect, diamond-moth and aphid.
After the agricultural products are covered with Greenhouse Insect Screen, they can effectively avoid the pests
such as the cabbage moth, the cabbage moth, the twill moth, the yellow trestle beetle, the ape leaf beetle, the aphid
and so on.
According to experiments, the protective effect of insect-resistant net on green cabbage, asparagus bean pod bean
pod bean pod bean pod bean asparagus fly, and Asparagus coat fly is 94-97%, and 90% of the protective effect on
2, can prevent disease.The spread of the virus can have disastrous consequences for greenhouse planting, especially
for aphids.However, after installing insect-proof net in greenhouse, it cut off the way of virus transmission, greatly
reducing the incidence of viral diseases, and the control effect is about 80%.
3. Adjust air temperature, earth temperature and humidity.In the hot season, the greenhouse was covered with a white
morning and evening was even with the open ground, and the sunny noon was about 1℃ lower than the open ground.
In early spring, march-April, the air temperature in the Greenhouse Insect Screen covering shed is 1-2℃ higher than
that in the open field, and the ground temperature of 5cm is 0.5-1℃ higher than that in the open field, which can effectively
In addition, the insect-control net can prevent part of the rain from falling into the shed, reduce the field humidity, reduce
the incidence of disease, sunny days can reduce the moisture evaporation in the shed.
4. Shading effect.Summer light intensity, strong light will inhibit the vegetative growth of vegetables, especially leafy
vegetables, and Greenhouse Insect Screen can play a certain role in shading, 20-22 mesh silver gray insect repellent net
in the general shading rate of 20-25%.
