摘　　要：草甸土经过水耕熟化和旱耕熟化过程分别被定向培育成草甸型水稻土、菜园土和旱田土，使原有草甸土的土体结构和理化性质发生改变研究认为，精耕细作、合理灌溉能促进土壤的熟化，旱田土的粗放式耕作使对土壤熟化的人为因素影响较小.Under different cropping systems(water cultivation and dry cultivation) meadow soil,can be oriently developed to be paddy soil, vegetable soil and dry farmland soil, which changes original soil structure and physical and chemical characteristics. The result of our research showed that intensive cultivation and rational irrigation promoted mellowness, but extensive cultivntion reduced the influence of artificial factors in dry farmland.
