杀草地膜由沈阳化工研究院和河北省冀县农药厂研制而成。是以低密度聚乙烯和低压低密度聚乙烯为原料,混以除草剂和助剂,通过吹型加工成的农作物地面覆盖栽培用膜。宽度一般是900毫米左右,厚度0.014毫米左右,存放半年时间,仍有较好的药效。经过田间应用的杀草地膜,其中的除草剂有95%以上被释放出来。对粮食和经济作物的生长,安全无药害,比普遍地膜加喷施除草剂方便、
Grassland film by the Shenyang Chemical Industry Research Institute and Hebei Ji County pesticide plant developed. Is based on low-density polyethylene and low-pressure low-density polyethylene as raw materials, mixed with herbicides and additives, through the blow molding processed crop cover film. Width is generally about 900 mm, thickness of about 0.014 mm, store six months time, there is still good efficacy. After the field application of grass film to kill, of which more than 95% of herbicides were released. The growth of food and cash crops, safe and harmless than the general film plus spraying herbicides convenient,
