Abstract: This paper introduces the techniques of returning whole corn stalk into soil，necessary agricultural machinery，operational technology，and their influence on wheat growth and its yield．The study shows that the rotten rate of corn stalk in one-year rotten period can reach more than 90％ ．If plough depth is more than 20cm ，95％ of corn stalk can be covered under soil with a depth of about 8cm ．This can guarantee the seeding quality of wheat．The basic seedings and tillers are increased by 23 and 0．2 comparing with traditional way．The dry matter weight and 1000-grain weight by returning whole corn stalk into soil can increase 8．95％and 1．33％．The winter wheat yield can increase 3．81％．
