反射农用薄膜正在农业上被用于防治虫害。美国加州大学研究表明,反射薄膜能驱除蚜虫、桔黄粉虱和叶蝉,而这些虫害用杀虫剂难以控制。此外,反射薄膜在促进植物生长和提高作物收获量上比黑色、白色或其他颜色农用薄膜更为有效。昆虫看到从薄膜反射的紫外线光就避开了它。试验显示:反射薄膜使番茄出现斑点双生病毒比使用白色农用膜晚了10周;使用反射薄膜的植物产量明显增加。目前,反射薄
Reflective agricultural films are being used in agriculture to control pests. Research at the University of California, U.S.A. shows that the reflective film repels aphids, whiteflies and leafhoppers, which are difficult to control with pesticides. In addition, reflective films are more effective than black, white, or other color agricultural films in promoting plant growth and improving crop yields. The insect avoided it by seeing the ultraviolet light reflected from the film. Tests showed that the reflective film produced spotted geminivirus in tomato for ten weeks later than the white agricultural film; the yield of plants using the reflective film increased significantly. At present, reflective thin
