Research on the Application Effect of Straw Return Technology in Soil Improvement and Its Mechanism
As an important agricultural waste resource utilization technology,straw return to field can not only effectively reduce environmental pollution,but also significantly improve soil structure and fertility.This study reviewed the appli-cation effect of straw return technology in soil improvement and its mechanism.By analyzing the related research litera-tures at home and abroad,the effects of straw return on soil physical properties(e.g.,soil structure,aeration and water retention),chemical properties(e.g.,organic matter content,nutrient supply)and biological properties(e.g.,mi-crobial community structure,enzyme activity)were investigated.Meanwhile,the study also revealed the specific process of straw return to the field to enhance soil quality and fertility through the mechanisms of increasing soil organic matter,improving soil nutrient cycling,and promoting microbial activities,and proposed the direction of future research and op-timization suggestions in practical applications.The results of the study show that the rational use of straw-returning technology can realize the sustainable development of agriculture and improve crop yields and soil health.
