Attention Should Be Paid To The Use Of Insect Protection Net

Update:14 Oct

  Pest control is very important and difficult management in greenhouse management. Therefore, some farmers now cover the insect protection net with an insect protection net, which can eliminate cabbage caterpillars, diamondback moths, aphids, and other pests. But few farmers know the precautions in its use.

  1. Matters needing attention

  Choose a suitable sunshade net: First consider the mesh, color, and width of the gauze. If the mesh is too small and the mesh is too large, it will not achieve the desired insect-proof effect; and if the mesh is too large and the mesh is too small, although it can prevent insects, the ventilation is poor, resulting in high temperature and too much shading. It is beneficial to the growth of crops; generally, 22-24 meshes of inspecting protection net should be used. Compared with summer, spring and autumn, the temperature is lower and the light is weak, so a white insert protection net should be used; in summer, to take into account the shading and cooling, a black or silver-gray insert protection net should be used; in areas with serious aphids and virus diseases, to To repel aphids and prevent virus diseases, silver-gray insect protection net should be used.

  2. Pre-coverage processing

  Soil disinfection and chemical weeding should be carried out before covering with an insect protection net. The germs and pests remaining in the soil must be killed before covering them with an insect protection net, and the source of insects should be killed. This is the key link to ensure the covering effect of the insect protection net.

  The quality of the coverage

  The insect protection net should be fully closed and covered, the soil should be compacted in the vicinity, and the lamination line should be used to fix it firmly. The small arched shed insert protection net is covered and cultivated, and the height of the shelf is higher than the crop, to prevent the vegetable leaves from clinging to the insert protection net, to prevent pests from eating outside the net or laying eggs on the vegetable leaves; the insert protection net used for closing the air outlet, There should be no gaps between the film and other coverings, so as not to leave access for pests; check and repair the holes and gaps on the plastic insert protection net at any time.

  4. Seedlings

  When planting, the seedlings should be brought into the greenhouse with medicine, and robust plants without pests and diseases should be selected.
