摘要
宿根甘蔗衰退是阻碍我国甘蔗产业发展的重要障碍之一,宿根甘蔗生产过程中随宿根年限增加病虫害加剧,在产量、品质等方面呈现降低趋势。针对宿根甘蔗生产中的实际问题,结合相关文献报告,本文从土壤营养失调、根系分泌物积累、土壤微生物区系变化、病虫害发生等方面阐述了宿根甘蔗衰退机理,介绍了提高甘蔗宿根年限的主要措施,并对延缓宿根甘蔗衰退的相关技术的研究进行了展望。
Recession of ratoon crops presents a major bottleneck of sugarcane development in China. Incidences of diseases and insect pests increase along with successive ratoon crops,leading to declinedyield and poor quality. By addressing practical problems and relevant literature, this paper discusses recession mechanisms of ratoon sugarcane in terms of soil nutrient imbalance, root exudates,change of soil microorganisms,and disease and pest damages. The paper also presents methods of increasing ratoon cycles and recent developments of relevant research,amelio rative measure,and advanced technologies.
