Abstract: The Zero-tillage is a practical technology in china and played a very important role to sustainable agriculture development. The article introduces the definition, principle, function and history, development of zero-tillage, conclude the discusses of Zero-illage system on soil water content, soil temperature physics, soil chemistry, soil micro-biomass and crops growth, development, yield, benefit: In Zero-tillage system, soil water evaropation was reduced by crops straw so water content was increased, that was good to crops growth; Soil temperatures was decreased by crops straw, especially in spring, that made serious problem in crops growth. At the same time, In Zero-tillage system, soil construction and account and activision of soil micro-biomass were relative stabilize, that benefited increasing nutrient utilization radio and crops growing. At the yield and benefit aspects, zero-tillage system benefit increasing yield, especially increasing benefit.
