How To Use Shade Nets To Prevent Insects?

1. Select appropriate specifications. The specifications of the insect-proof greenhouse shade net mainly include the content, such as width, aperture, wire diameter, and color. In particular, the aperture and the density of the shade net for insect-proof greenhouses are generally calculated by the number of meshes. Too few meshes and large meshes will not achieve the desired insect control effect; too many meshes and small meshes will increase the cost of insect control. The suitable number of meshes currently recommended for production is 24 to 30 meshes. The wire (wire) has a diameter of 14 to 18 mm and a width of 1.0 to 1.8 meters, mainly white.

2. It must be covered during the whole growth period. Insect-proof greenhouses have less shading nets, and do not need to cover them day or night or front cover and rear cover. They should be covered all the way and do not give insects the opportunity to invade. Need to press the network cable firmly to prevent being blown away by the wind.

The middle shed cover is to cover the awning net on the scaffold. In this way, the utilization rate of the shed is improved, and the management of entering the shed is convenient. The covering of the small shed is to cover the small awning net on the small shed. In this way, it is not limited by the shed, with less investment, and it is easier to popularize and apply. However, the height of the small scaffold should be higher than the height of the newly cultivated vegetables, so as to prevent the vegetables from clinging to the shade net to feed the pests and have the opportunity to hatch.

The greenhouse shading net can not only prevent insects, but also play a shading effect, and its construction is very simple. Generally only two people are needed. Vegetables are most suitable for planting.
