Information

Covering the cultivation of fast-growing leafy vegetables with insect-proof nets can prevent pests without pesticides, thereby greatly reducing the amount of pesticide residues in vegetables. In order to achieve a good insect control effect, the following technical points should be mastered when covering the insect net.
1Choose a suitable insect net. 20-32 mesh, wire diameter of 0.18 mm should be used to prevent insect nets.
2. The height of the arch shed should be higher than the height of the crops, otherwise the vegetable leaves are close to the insect-proof net, and the flea beetles and other pests outside the net can still eat the vegetable leaves, or lay their eggs on the vegetable leaves, causing harm.

3. Implement the coverage of the whole reproductive period. Insect-proof nets can block light, but there is not much shading. When watering, pour the water directly on the insect-proof net, and the phenomenon of falling seedlings will not occur. Due to the implementation of full coverage, soil disinfection and chemical weeding must be carried out before covering the net to kill the bacteria and pests remaining in the soil and cut off the transmission route of diseases, pests and weeds.
4. The perimeter of the insect net is tightly closed to prevent adult pests from sneaking in and laying eggs. The surrounding area should be compacted, and the mesh between the arches should be tightened to prevent the wind from blowing the mesh.
5. Timely increase temperature and humidity. When the temperature is particularly high, increase the number of water supply, maintain the humidity in the network, and reduce the temperature.
