The Mesh Insect Screen can be used for both sun protection and insect control, and can be used all year round. Pay attention to the use of insect nets:

1. Cover the whole process during the growing period of vegetables. The anti-insect net has a small shading rate and should be covered throughout the process without giving the pests an opportunity to invade. After the insect-proof net device, the bricks or clods are pressed at both ends, and the net needs to be pressed with a pressure cable to prevent it from being blown away by the wind.

2. Pick the right standard. The standards of Insect Screens mainly include undulations, apertures, wire diameters, colors, and the like. In particular, the pore size is generally calculated by the number of meshes. The number of meshes is too small, the mesh is large, and the insect-preventing effect should not be achieved. The number of meshes is too large, the mesh is small, and the insect-preventing effect is good, but the cost is increased. At present, the insect-proof nets recommended for use in production are between 24 and 40 mesh.

3, Pest control should be combined with chemical control. Some farmers think that if they spend money to buy insect nets, they don't have to worry about controlling insects. In fact, insect nets can only avoid pests from invading. If there are insect pests in the shed, chemical control is still needed.

The current Shading Net is mainly used in the summer, especially in the south. Some people describe it: the winter in the north is white (film cover), and the summer in the south is black (covering the shade net). The use of shading nets to cultivate vegetables in the south in the summer has become a major technical measure for disaster prevention protection. The current application in the north is limited to summer vegetable seedlings. In summer (June-August), the main function of covering the sunshade net is to prevent the sun from illuminating, the impact of anti-storm, the danger of high temperature, and the spread of pests and diseases, especially to prevent the migration of insects.
