摘　　要：推广机械化收获是我国甘蔗产业提质增效的重要途径。针对机械化收获后宿根蔗发株出苗差、缺苗断垄严重、宿根衰退减产等问题,从机收后蔗蔸破损程度、根系水分养分吸收状况以及对土壤理化性质影响等方面对宿根蔗衰退机理进行了探讨。就目前我国甘蔗机械化收获的发展现状,对品种选育、农艺栽培、土壤改良等方面提出了相应措施。Promotion of sugarcane machine harvest is an important way to improve the quality and efficiency of Chinese sugarcane industry.Aiming at the problems of poor seedling emergence,severe gapping,and declined ratoon crop yields,and so on,the extent of damage to the base of stalks and changes in nutrient and absorption of the root system and the physical and chemical properties of soil after machine harvest and how these changes may cause declining yields of ratoon crops were discussed.To cope with the current development trend of sugarcane mechanical harvest in China,technical measures in variety selection and breeding,cultural practice,and soil improvement were proposed.
