遮阳网,是以聚烯烃为主要原料,经拉丝编织而成的塑料网,是继农膜之后又一重要新型复盖材料。经嘉兴市城区对遮阳网在蔬菜复盖栽培技术的试验、示范,三年来已推广面积达万亩茬次。一、技术效应1.遮强光、降高温。目前,我国菜用遮阳网的遮光率可达35—75%。各地按不同蔬菜的光饱和点,选用适宜遮光率的遮阳网,有效地防止了因光照过强而阻碍蔬菜生长发育的现象。遮光效应伴随着显著的降温效果,防止 Shade net, is a polyolefin as the main raw material, woven by the wire drawing plastic mesh, after the plastic sheeting is another important new cover material. After the city of Jiaxing sunscreen net in the cultivation of vegetable cover technology test, demonstration, three years has been the promotion of an area of ​​mu mu. First, the technical effects 1. Cover light, lower temperature. At present, the shading rate of China’s vegetable shade net can reach 35-75%. Depending on the light saturation point of different vegetables, the shading net with appropriate shading rate is effectively used to effectively prevent the growth of vegetables due to the excessive light intensity. Shading effect with a significant cooling effect, to prevent
