摘要
秸秆原位还田是苏中地区秸秆综合利用最为常见的方式。结合实地调研辩证分析机械化秸秆全量还田对土壤的理化性质、病虫害防治作用、产量以及环境的综合影响,并针对原位还田存在的不利影响提出秸秆快速腐熟或深耕、控制秸秆还田量、控制回归水污染等改进措施和建议。
Straw-returned-native-field is the most common comprehensive utilization of straw in the central region of Jiangsu Province. Based on the investigation,this paper analyzes the comprehensive effects of mechanized straw returning on soil physical and chemical properties,pest control,yield and environment dialectically. In view of the adverse effects of straw-returned-native-field,the paper puts forward some improvement measures and suggestions,such as rapid ripening,deep tillage,control of land return amount,and control of return water pollution.
