【摘要】 秸秆还田既可避免秸秆资源堆放浪费,也可防止其大量焚烧而造成环境污染,同时利于培肥土壤,提高土地的可持续利用。该研究结合近年来秸秆还田的相关研究进展,阐述了秸秆还田对土壤物理、化学及生物学性质的影响,进一步揭示了秸秆还田在改善土壤环境方面的重要作用,指出了当前秸秆还田技术所存在的问题,并提出建议及展望,旨在为开展秸秆还田培肥土壤的机制研究提供参考依据。更多还原

【Abstract】 Straw returning can not only avoid the waste of stacking resources,but also prevent it from causing environmental pollution caused by a large number of incineration,and at the same time it is beneficial to fertilize the soil and improved the sustainable use of the land.This study combined with the recent research progress of straw returning to the field,expounded the impact of straw returning on soil physical,chemical and biological properties,and further revealed the important role of straw returning in improving soil environment.The problems of the current straw returning technology were pointed out,and suggestions and prospects were put forward.The aim was to provide a reference for the research on the mechanism of straw returning to fertilize the soil.更多还原
