Abstract: To solve the problem of the shallow plough layer and low soil fertility,to explore the reasonable and effective technology of straw returned,this research used the positioning test for five years of the two factors split plot design of the tillage and the straw returned to analyze the effects of the straw returned in combination with deep loosening and increasing nitrogen application to the soil physical and the chemical properties. The results showed that deep scarification could reduce the soil bulk density,porosity,organic matter content and available K content,on the other hand it could increase the field capacity,alkaline hydrolysis N and available P content; straw returned could reduce the soil bulk density,field capacity,alkaline hydrolysis N and available K content,otherwise it could increase the porosity,organic matter and available P content; straw returned with nitrogen could reduce the soil bulk density,organic matter content of the surface layer,available K content,it could increase the soil porosity and field capacity,organic matter content of the nether layer,alkali-hydrolyzable N of the surface layer,available P content; straw returned in combination with deep scarification could reduce porosity and alkali solution N of the surface layer,available K content,and increase the soil bulk density,lower porosity of the nether layer,field capacity,organic matter and available P content of the surface layer.
