为了用好除草剂,必须了解除草剂的作用原理,掌握除草剂的作用与各种环境因素的关系。其中,除草效果与土壤的关系是很重要的一个方面。从五十年代以来新发展的除草剂品种中,土壤处理剂占优势;还有不少除草剂兼有土壤和茎叶活性;有些除草剂虽然缺乏土壤活性,但在使用中总有相当大的一部分要落入土壤。因此除草剂在土壤中的动态是不可回避的问题。 In order to make good use of herbicides, we must understand the role of herbicides, master the role of herbicides and a variety of environmental factors. Among them, the relationship between herbicidal effect and soil is a very important aspect. Among the newly developed varieties of herbicides since the 1950s, soil treatment agents predominate; there are also many herbicides that have both soil and stem and leaf activity; while some herbicides, although lacking soil activity, are generally quite large in use Part of the soil to fall into. Therefore, the dynamics of herbicides in the soil is an unavoidable problem.
