  After several years of development, the covering technology of vegetable greenhouse insect-proof net has been recognized and trusted by many growers, and the speed of improvement is very fast. Today, the manufacturer of vegetable greenhouse insect-proof net briefly clarifies the selection of specifications for vegetable greenhouse insect-proof net, hoping to help you apply the technology of insect-proof net.
  目前农业消费上蔬菜大棚防虫网应用的主要有3类。以满足不同蔬菜种类对光照的请求和忌避害虫的需求。一是银灰色或铝箔条防虫网。其避蚜效果好,且可降低棚内温度;二是白色防虫网,其透光率较银灰色的好,运用较普遍,但夏季棚内温度略高于露地,适用于大多数喜光蔬菜栽培;三是黑色防虫网,其遮阳降温效果好。目前市场上供给的蔬菜大棚防虫网,宽幅普通1-2.4米,可依据实践状况选择。目数代表防虫网孔径大小,目数过多,网眼大,起不到应有的防虫效果,目数过多,网眼小,会增加棚内温度及消费本钱。夏秋大棚掩盖防虫网以18-25目银灰色最为适合,即可阻隔其成虫进入网内。
蔬菜大棚防虫网
  At present, there are three main types of insect-proof net applied in vegetable greenhouse in agricultural consumption. To meet the requirements of different vegetable species for light and pest avoidance. One is silver grey or aluminum chaff insect-proof net. Its aphid avoidance effect is good, and can reduce the temperature in the shed; the second is the white insect-proof net, whose light transmittance is better than silver-gray, which is widely used, but the temperature in the shed in summer is slightly higher than that in the open field, which is suitable for most light-loving vegetable cultivation; the third is the black insect-proof net, whose sunshade and cooling effect is good. At present, the vegetable greenhouse insect-proof net on the market is 1-2.4 meters wide, which can be selected according to the practice. Number of meshes represents the size of the hole of the insect-proof net. Too many meshes, too large meshes, can not achieve the desired insect-proof effect. Too many meshes and too small meshes will increase the temperature and cost of consumption in the shed. In summer and autumn greenhouses, 18-25 mesh silver gray is the most suitable for covering the insect-proof net, which can prevent the adults from entering the net.
