1、轻便、简易、节约成本。
1. Portability, simplicity and cost saving.
2、能有效地改善作物生长环境，减轻灾害为害。遮阳网的主要作用是防止强光高温、暴雨、大风、霜冻及鸟虫等危害，可为作物生长发育提供良好的环境条件。夏季晴天日照强度往往超过10万Lx，而一般绿叶菜的适宜光照强度为2万~3万Lx。夏季用遮阳网覆盖后，地表温度一般可降低4~6℃，地下5厘米处地温降低3~5℃，地上30厘米处气温降低1℃左右。若作地上浮面覆盖，地下5厘米处地温可降低6~10℃。用黑色网覆盖，地表温度降低9~13℃，地下5厘米处降低4~7℃。所以用遮阳网覆盖后可使光照强度降低到作物生长适宜的范围内，以利光合作用的进行。
2. It can effectively improve crop growth environment and mitigate disaster. The main function of shading net is to prevent the hazards of strong light, high temperature, heavy rain, strong wind, frost and birds and insects, which can provide good environmental conditions for crop growth and development. In summer, sunshine intensity often exceeds 100,000 Lx on sunny days, while the suitable light intensity of common green leafy vegetables is 20,000-30,000 Lx. After covering with shading net in summer, the surface temperature can generally be reduced by 4-6 C, the ground temperature at 5 cm underground can be reduced by 3-5 C, and the ground temperature at 30 cm underground can be reduced by about 1 C. If covered with floating surface, the ground temperature at 5 cm underground can be reduced by 6-10 C. Covered with black mesh, the surface temperature decreases by 9-13 C and 4-7 C at 5 cm underground. Therefore, the light intensity can be reduced to a suitable range for crop growth after covering with shading net, so as to facilitate photosynthesis.
