Mechanized conservation tillage is the use of field machinery or harvesting machinery directly crushed straw evenly sprinkled on the surface, and then the implementation of mechanical (less) tillage in order to improve the soil structure, fertility, drought resistance and reduce wind erosion, water erosion , Cost-effective section, to achieve sustainable agricultural development of an advanced farming techniques. First, the advantages of conservation tillage
