Abstract: Applying agricultural techniques through straw returning and deep pine to improve soil，improve soil fertility，increase soil quality，and then achieve crop yield.Through three years of comparative experiments，shallow rotation（RT），tillage（P），deep pine（S），tillage+straw returning（P+R）and deep pine+straw returning（S+R）five treatment soil samples were set，through comparison，it was found that straw returning with deep pine agricultural application technology was better than traditional farming，yield was improved，effective improvement and fertility.
