除草地膜是在薄膜加工工艺中加入选择性广谱除草剂,经搅拌共混后吹塑而成。它使除草剂均匀混在地膜内,覆用后经湿气水珠萃取,逐渐释放药效,让杂草中毒死亡。除草地膜与普通地膜相比,农作物每亩节省人工除草用工5人,蔬菜每亩节省人工除草用工9人,每人工值按6元计算,可分别节省工值30元和54元。除草地膜虽比普通地膜每亩多投入4-6元。
Weeding film is in the film processing technology by adding selective broad-spectrum herbicides, after blending by blow molding. It evenly mixed herbicides in the film, after coating with moisture beads extraction, the gradual release of efficacy, weeds poisoning death. Compared with ordinary mulching film, weeding mowed crops saves 5 people laboring for artificial weeding and vegetables, saving 9 artificial mowing workers per mu. Each worker value is calculated according to 6 yuan, which can save 30 yuan and 54 yuan respectively. Although the weeding film than the average investment per mu mu 4-6 yuan.
