摘　　要：将稀土转光粉和其他助剂添加到聚乙烯树脂里 ,制得新颖的耐候光转换无滴农膜 .它与长寿无滴农膜相比较 ,具有将紫外光转换成红光的特殊功能 ,可提高棚温 ,促进光合作用 。A novel farm film with weatherability and non fog-drop and light trans form was produced by adding rare earth light transform agents and other auxiliar ies in polyethylene resin. Compared with long-term durable and non fog-drop f ilm, the novel film possessed special function of converting ultraviolet light t o red light, thus can increase temperature in the shed, and can also it speed up photosynthesis, improve yield and the quality of the crops.
