First, the origin of no-till law “No-till law” is the name proposed by foreign countries in the past 30 years, in fact, in our country has 2,000 years of history. No-tillage method of modern science, also called minimum tillage method, soil and water conservation tillage method, conservation tillage method. It is based on the modern theory of agricultural science and agricultural machinery and chemical industry based on. It is not without plowing at all. Instead, it completes ditching, sowing (or transplanting), fertilizing, covering, spraying and other operations at a time with small farming scenes. Eliminate many unreasonable, unnecessary farming. In order to increase production at the same time, to maximize the protection of soil structure, fertility and directional fertility. The traditional farming method is based on plowing, farming more times, aggravating the damage to the soil structure, increasing soil and water
