遮阳网主要应用在夏季，尤其是南方推广面积大。有人形容说：北方冬季是一片白(薄膜覆盖)，南方夏季是一片黑(覆盖遮阳网)。夏季在南方利用遮阳网栽培蔬菜已成为防灾保护的一项主要推广的技术措施。北方应用还只限于夏季蔬菜育苗。夏季(6—8月)覆盖遮阳网主要作用是防烈日的照射、防暴雨的冲击、高温的危害、病虫害的传播，尤其是对阻止虫害迁移起到很好的作用。
Sunshade nets are mainly used in summer, especially in the southern region with a large promotion area. Some people describe it as: winter in the north is covered with white film, while summer in the south is covered with black film. The use of shading nets to cultivate vegetables in the south during summer has become a major technical measure for promoting disaster prevention and protection. The application in the north is still limited to summer vegetable seedling cultivation. In summer (June August), the main functions of covering the sunshade net are to prevent the exposure of hot sun, the impact of rainstorm, the harm of high temperature, the spread of diseases and pests, especially to prevent the migration of pests.
夏季覆盖后起到一种挡光、挡雨、保湿、降温的作用；冬春季覆盖后还有一定的保温增湿作用。
After covering in summer, it plays a role in blocking light, rain, moisturizing, and cooling; After covering in winter and spring, there is also a certain degree of insulation and humidification effect.

掩盖遮阳网后，因为降温防风效果，下降了掩盖区空气和外界的沟通速度，就明显进一步增加空气相对湿度，中午时，湿度增加值最大，一 般达型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵到13-17%，湿度高，土壤蒸发量下降，增加了土壤湿度。
After covering up the shading net, due to its cooling and windproof effect, the communication speed between the air in the covered area and the outside world is reduced, which significantly further increases the relative humidity of the air. At noon, the maximum increase in humidity is usually 13-17%, with high humidity and a decrease in soil evaporation, increasing soil humidity.
遮阳网是采用聚乙烯(HDPE)， 高密度聚乙烯、PE、 PB、PVC、回收料、全新料、聚乙丙等为原材料，经紫外线稳定剂及防氧化处理，具用抗拉力强、耐老化、耐腐蚀、耐辐射、轻便等特点。
The sunshade net is made of polyethylene (HDPE), high-density polyethylene, PE, PB, PVC, recycled materials, brand new materials, polyethylene propylene, and other raw materials. It has been treated with ultraviolet stabilizers and anti oxidation treatment, and has the characteristics of strong tensile resistance, aging resistance, corrosion resistance, radiation resistance, and portability.
