传统的耕作方法在农业生产上对控制病虫和杂草的危害、疏松土壤及作物生产虽起到一定的作用,但土壤经过年复一年的反复耕耘之后,破坏了土壤的团粒结构,引起土壤板结,导致水土流失和地力衰退。近20年来,随着化学除草剂在农业生产中的成功使用以及面对着水土流失的事实,一种新的耕作制度——少耕和免耕法便应运而生。目前已有几十个国家对这种新的耕作方法进行了不同程度的试验、推广和应用,并取得良好
Traditional methods of farming have played a role in controlling pests, weeds and weeds in agricultural production. Loose soils and crop production play a role. However, after years of repeated cultivation, the soil destroys soil aggregate structure and causes Soil compaction, leading to soil erosion and land degradation. In the recent 20 years, with the successful use of chemical herbicides in agricultural production and the fact of water and soil loss, a new cropping system, namely, tillage and no tillage, came into being. At present, dozens of countries have tested, popularized and applied this new farming method in varying degrees and achieved good results
