Abstract: The feasibility of protective tillage was introduced in this paper .The experiment showed that the techniques of protective tillage were reasonble in economy.It can prompt the correct circulation for the ecological environment. It also can be used in the production widely.The needed machinery was selected and the operating schames was drawn up in order to demonstrate this kind of technique.
