Study on the Effects of Returning Straw to the Field on the Geological Structure of Black Soil and Maize Yield in Northeast China
In order to clarify the effect of straw returning on soil structure and maize yield in black soil in Northeast China,based on long-term positioning experiments,this article summarizes the changes in soil bulk density,compaction,and water holding capacity after straw returning to the field,as well as the effect of straw returning to the field on maize yield,aiming to provide a reference for further improving maize yield.
