同时覆盖遮阳网后，以遮光降温的同时，还可减缓风速，减少土壤水分的蒸发，有利于保湿防早，并降低暴风雨对蔬菜造成的机械损伤、泥沙污染及土壤板结对蔬菜的危害。此外，还能减少病虫为害。如用银灰色网覆盖，可以避免蚜虫危害，减少病毒病;采用封闭式全天覆盖，可以防止菜粉蝶、小菜娥、斜纹夜蛾等多种害虫在蔬菜上产卵，使虫害减径，实现作物的无农药和少农药栽培。现在遮阳网除大量用于夏秋季节蔬菜栽培，缓解秋淡外，主要用在高温多雨或容易发生病毒病危害的地区培育甘蓝、白菜、芥菜、芹菜、葛苣、番茄、黄瓜等幼苗，可以提高出苗率，保证全苗、壮苗。
At the same time, covering the shading net can slow down the wind speed and reduce the evaporation of soil moisture, which is conducive to moisturizing and preventing early, and reduce the mechanical damage caused by storms to vegetables, sediment pollution and the harm of soil compaction to vegetables. In addition, it can also reduce pests and diseases. If covered with silver-gray net, aphid damage can be avoided and virus diseases can be reduced. Closed all-day covering can prevent many pests, such as rapeseed butterfly, cabbage E, Spodoptera litura, from laying eggs on vegetables, reduce the diameter of pests, and realize pesticide-free and less pesticide cultivation of crops. Nowadays, shading net is mainly used to cultivate seedlings of cabbage, cabbage, mustard, celery, pueraria, tomato and cucumber in hot and rainy areas, besides a large amount of vegetable cultivation in summer and autumn season to alleviate the autumn light. It can improve the emergence rate and ensure the whole seedling and strong seedling.
防寒。冬季代替秸秆、落叶流水槽模具 u型槽模具 电缆槽模具 隔离墩钢模具 护坡砖模具 钢制闸门 螺杆式启闭机 卷扬式启闭机进行覆盖，可以防霜、防寒、防冻，有利于实现冬季蔬莱稳产优质。
Cold proof. In winter, instead of straw and deciduous leaves, covering can prevent frost, cold and frost, which is conducive to achieving stable yield and high quality of vegetables and vegetables in winter.
