摘要
为明确秸秆还田对东北地区黑土地的土壤质构和玉米产量的影响,以长期定位试验为基础,总结秸秆还田后的土壤容重、紧实度和持水量等指标变化及秸秆还田对玉米产量的影响,旨在为进一步提高玉米产量提供参考.
Abstract
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.
