Straw Returning Field and Deep Pine Agricultural Application Technology Compared with Traditional Agricultural Farming Technology

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.
