What Are The Benefits Of Using A Greenhouse Insect Protection Net?

Update:31 Dec

  Greenhouse insect protection net is made of high-density polyethylene, which is resistant to aging, corrosion, and non-toxic. It looks like a screen window with a service life of 3 to 5 years. The common color is white, but black or silver-gray can also be selected according to different crop varieties. Its specifications include 20 mesh, 24 mesh, 32 mesh, 40 mesh, and 50 mesh, and the regular width is 1m. The use of greenhouse insect protection net has the following advantages:

  (1) Insect control

  After covering the insect protection net, because the mesh is small, most vegetable pests cannot penetrate the mesh, so a barrier is formed to prevent pests from entering. Covering a 20~30 mesh insect protection net can eliminate the harm of leaf miners, aphids, fleas, cabbage butterflies, diamondback moths, and other major pests in the shed.

  (2) Anti-viral disease

  Vegetable virus diseases are usually spread by aphids, rice planthoppers, whiteflies, and other pests. Insect protection net prevents vegetable pests from entering, cuts off the transmission route of vegetable virus diseases, and reduces the occurrence of vegetable virus diseases.

  (3) Reduce the use of pesticides

  Without the use of an insect protection net, vegetable production is highly dependent on pesticides, especially in summer and autumn. Pests and diseases occur frequently, cultivation is difficult, and the frequency and dosage of chemical pesticides are high. After covering the insect protection net. The number of vegetable pests is significantly reduced or does not occur, which greatly reduces the use of pesticides, and even achieves the effect that no pesticides are used in the vegetable growing season, and the quality of vegetables is also improved.

  (4) Prevent typhoons and rainstorms

  Summer gale, heavy rain, and hail will cause mechanical damage to vegetable crops, resulting in seedling drops and dead seedlings. After covering the insect protection net, due to the small mesh size and high strength, after the heavy rain hits the insect protection net, the net becomes drizzle, and the impact is weakened, which is conducive to the growth and development of vegetables.

  (5) is good for nursery

  June to August is the autumn vegetable seedling season. It is in a period of high temperature, heavy rain, and high incidence of diseases and insect pests. It is difficult to raise seedlings. After using the insect protection net to protect the seedlings, the emergence rate is high, and the seedling period rate is high, which lays a good foundation for the production of autumn and winter vegetables.

  (6) Sunshade cooling

  After covering the greenhouse insect protection net, the air temperature and ground temperature can be lowered by 2~3℃ compared with the open field, and there is not much shade.
