摘　　要：随着甘蔗机械化水平的逐步提高,蔗田机械作业程度增加,机械压实造成蔗区土壤理化特性和生物学性能改变,甘蔗地下部根系生长发育受到影响,最终导致甘蔗产量降低、品质下降。针对目前我国蔗田机械化压实现状,探讨蔗田机械压实对土壤理化特性、甘蔗根系生长发育变化规律等的影响,并从机械改良、配套农艺技术、耕作模式等方面提出改良措施,对我国甘蔗全程机械化具有一定的积极推进作用。As the development of sugarcane mechanization,mechanical operation in sugarcane fields has increased.The mechanical compaction changed the soil physical,chemical and biological properties in the sugarcane fields,which affected the growth and development of the root system,eventually leading to a decrease in sugarcane yield and quality.The mechanical compaction situation of sugarcane field in China was described and the effect of mechanical compaction on the soil physical and chemical properties and the growth and development of sugarcane root system in the sugarcane fields was discussed,based on which some suggestions were put forward from the aspects of machinery improvements,agronomic practices and tillage patterns,which might have positive effect on the sugarcane mechanization in China.
