What about the key points for selecting flour mesh?...

Vegetables, flowers, etc. all need to be treated for pests and diseases. Pests and diseases are more difficult. Installed nylon mesh is more useful. The nylon mesh is formed by weaving abrasion-resistant raw materials, which can effectively prevent insect pests for a long time. You can use more than just one season!

Insect nets can be used to protect pests such as whitefly and aphids in summer to protect large areas of vegetables from viral diseases. In winter, insect nets can effectively prevent the occurrence of chapped fruits. The reason for the cracking is that the cold air blows directly on the fruit surface after the top air vent is opened.

The air outlet is installed with nylon mesh. It can effectively prevent fruit cracking and leaf injury caused by cold wind.

In addition to preventing the cold wind from blowing directly, setting up insect-proof nets under the air outlets can also prevent foreign objects from entering the shed, especially for vegetable farmers who still use straw curtains. Whenever the temperature starts to rise and the air outlet gradually expands, a large number of broken grasses fall. To plant leaves, it affects plant growth and leaf photosynthesis.

Nylon mesh selection: the mesh number, color and width of the gauze should be considered. If the number of meshes is too small and the mesh size is too large, the anti-insect effect will not be achieved; and if the number of meshes is too large, the mesh size is too small, although it can prevent insects, but the ventilation is not good, resulting in high temperature and excessive shading. Crop growth. In general, 22-24 mesh insect nets should be used. Compared with summer and spring, the temperature is lower and the sunlight is weaker. It is better to choose a white insect net; the small arch shed insect net should be covered and cultivated, and the height of the scaffold should be significantly higher than the crops. Feed outside or spawn on leaves. The insect-proof net used to close the air vent, and there must be no gap between it and the transparent covering, so as to prevent pests from entering and leaving the passage. Check and repair holes and gaps on the insect screen at any time.
