Technical Points Covered by Insect Nets

Insect nets for greenhouses can not only prevent pests, but also promote our harvest.

Although the application of insect nets increases the cost, after we apply them, we can not only prevent insect nets, but also reduce the use of pesticides, and the agricultural products can be sold at a good price! So it's still worth it.

As a new type of covering material, the insect-proof net not only has the advantages of sunshade nets, but also overcomes the shortcomings of sunshade. In summer, it can reduce the ground temperature by 2°C-4°C and the temperature by 30C-50C, which is beneficial to the growth of vegetables.

The anti-insect net also has anti-disaster effects such as preventing rainstorm erosion, and overcomes the influence of insect pests and disaster weather on vegetable production in summer and autumn. Insect-proof net-covered cultivation is one of the high-yield cultivation techniques for vegetables that has been vigorously promoted in recent years.

1. Must be covered in the whole growth period

The insect-proof net in the greenhouse has less shading, and it does not need to be covered day and night or the front cover and the back are uncovered. It should be covered all the way to prevent pests from invading, so as to receive satisfactory insect and disease prevention effects. When covered with an insect-proof net, the net also needs to be pressed firmly with a netting wire to prevent it from being blown away by the wind.

2. Select the appropriate specification

The specifications and standards of insect nets for greenhouses mainly include width, aperture, wire diameter, color, etc., especially the aperture. The density of the 50 mesh insect net suppliers is generally calculated by the number of meshes, that is, the number of mesh grids with a length of 2.54 cm. At present, 24-30 mesh is mostly used in production. The thread (silk) diameter is 14-18mm, the width is 1.0-1.8m, and it is mainly white.

3. Comprehensive support for various measures

In the insect-proof net-covered cultivation, it is necessary to actively adopt comprehensive measures such as increasing the application of corrosion-resistant organic fertilizers, using improved varieties resistant to diseases and insect pests, biological pesticides, and non-polluting water sources.

4. Properly use and keep carefully
