| Abstract: | Because of the predatory exploitations on land, human being has been suffered from castigation by nature, and the study of conservation tillage has been paid much attention. It is a common apprehension that conservation tillage is no/less tillage combined with straw mulching. Through the field monitoring results gotten from Bashang region, it is proposed that conservation tillage is not always no tillage, timing tillage on bad structural soil is also beneficial to the prevention of soil erosion. |
