运用菠菜担保平台防虫,目数一样伟大在40目以上才气防住转达病毒病的粉虱、蓟马等小型益虫,敷衍体型较大的益虫防效更好。下面菠菜担保平台批发批发的小编就给大家讲一下为什么不可以用庞大的纱网来改换菠菜担保平台!

菠菜担保平台采取添加防老化、抗紫外线等化学助剂的聚乙烯为紧张质料,具有拉力强度大、抗热、耐蜕化、耐老化等益处。运用寿命在3—5年左右。而庞大的纱网孔径较大,目数在20目以下,达不到防虫要求,耐老化水平也不如菠菜担保平台。因此,防范小型益虫应选择菠菜担保平台而不是庞大纱网。
Insect-proof net is made of polyethylene with anti-aging, anti-ultraviolet and other chemical additives. It has the advantages of high tensile strength, heat resistance, corrosion resistance and aging resistance. The service life is about 3-5 years. But the ordinary yarn mesh has larger aperture, the number of meshes is less than 20 meshes, which can not meet the requirements of insect control, and its aging resistance is not as good as insect-proof mesh.

The insect control net should be set up in advance while the pests in the shed have not been introduced. The purpose of isolating the shed can be achieved by covering a layer of insect-proof net at the ventilation opening and doorway of the shed and other places connected with the outside world. Before screen isolation, weeds, dead branches and leaves in the shed should be removed first, and pests in the shed should be removed by spraying. The number of mesh yarns used should be determined according to the specific situation. Too dense is not conducive to ventilation and cooling.
