Insect prevention net is an artificial barrier to keep pests out of the net, so as to achieve the purpose of insect prevention, disease prevention and vegetable protection. In addition, the light reflected and refracted by the insect prevention net can also drive away pests.

Insect prevention net covering technology of greenhouse orchard is an important technology that plays an important role in green organic agricultural planting. Do you know why it is necessary to cover insect prevention net in the whole growth period

This is mainly because the use of orchard pest control nets for vegetable cultivation in the south in summer has become an important technical measure for disaster prevention and protection.

The main effect of covering orchard with pest control net in summer is to prevent the exposure of hot sun, avoid the scouring of rainstorm, reduce the damage of high temperature and organize the spread of diseases and pests.

The orchard insect proof net does not cover much light, so it does not need to be uncovered day and night or sunny and overcast. It should be closed and covered throughout the growth period, and the net should not be uncovered until harvest.

When covering the greenhouse, the orchard insect proof net can be directly covered on the scaffold, and the surrounding area shall be compacted with soil or bricks to prevent pests from swimming into the greenhouse to lay eggs. The net must be firmly pressed with pressure wire to prevent strong wind from blowing the net away.

When the small arch shed is covered, the height of the shed shall be higher than the height of the vegetable crops. Generally, the arch height shall be more than 90 cm, so as to avoid the vegetable leaves clinging to the orchard insect prevention net, and prevent pests outside the net from eating the vegetable leaves and laying eggs.

The orchard insect screen is breathable, and the leaf surface is still dry after covering, reducing the occurrence of diseases.

It is light transmissive and will not “cover the yellow and cover the rotten” after being covered. The current orchard insect prevention net is generally applied in summer, especially in the south.
