摘　　要：通过对甘蔗叶粉碎还田前后土壤结构、营养成分以及还田技术方式进行分析和试验对比,初步探讨其主要原因,并提出了从种植、管理、技术手段等多方面相结合的控制技术措施。The practice of sugarcane leaf shattering and returning reduced the organic substance＇s waste and environmental pollution significantly and improved the soil structure,but it also comes along with such negative effects as increased insect pests,higher morbidity and no increased output and income,etc.After our analysis and experimental comparison on the soil structure and nutrient ingredient before and after sugarcane shattering and returning and its technologies and methods,their main reasons were discussed and control technologies by combining cultivation,management,technical measures and so on were also proposed.
