摘要

Over thousands years, tillage agriculture have played an overriding role in the traditional farms of China, Including the manipulation of plough, harrow and mid-plough. One of the advantages of the tillage system is the inhibition of weed and insect in soil. However, plough system is considered to be an inefficient use of time and fuel and caused much "wear and tear" to the machines (Waydelin, 1994). The unavoidable negative effects of intensive and repeated soil tillage in China are apparent on soilloss, diminishing of organic matter content, soil erosion, ecological environment (such as city slums and marginal populations), soil moisture, water infiltration, soil microbial population, loss of nutrients, and the degradation of soil physical structure. These results lead to a poor productivity of soil and poor yields over time. Soil in many places of China appeared to be poor, out of water and low nutrition. In order to maintain and improve soil fertility and water supplement no-till system possesses a specific implication for the sustainable agriculture of China.
