除草地膜简称药膜。它是一种伴随地膜栽培技术而产生的农药加工新剂型,即以地膜为载体,经特殊工艺方法制造的含有化学除草剂的复合膜。当前,药膜的研制,皆是把化学除草剂拌入颗粒塑料,经过吹塑而制成的。这种制造工艺,不仅受化学除草剂理化性质的限制,而且药膜最多只能有半数量的化学除草剂有效,另外半数量的化学除草剂则被浪费掉。为解决此问题,充分发挥其灭草作用,笔者进行了新法制造药膜的研究,提出了一种新工艺。
Weeding film called film. It is a new type of pesticide processing agent that accompanies the cultivation of plastic film, that is, a composite film containing a chemical herbicide manufactured by a special process using the plastic film as a carrier. At present, the research and development of the medicinal films are all made by mixing the chemical herbicides into granular plastics and blowing them. This manufacturing process is not only limited by the physical and chemical properties of chemical herbicides, but also can be effective with up to half the amount of chemical herbicides and half the amount of chemical herbicides. To solve this problem, give full play to its herbicidal effect, the author conducted a study of the new law making membrane, put forward a new technology.
