摘　　要：倒伏是水稻生产中普遍存在的问题,不仅制约了水稻高产、稳产和优质,也降低了水稻机械化收获效率。本文阐述了水稻的倒伏类型,水稻根系和茎秆形态、茎秆解剖结构及化学成分等与水稻倒伏的关系,并从选育抗倒品种、优化栽培方式、加强田间管理和应用化控技术等角度提出水稻抗倒途径,最后进行总结与展望。Lodging is a common problem in rice production,which not only restricts the high and stable yield as well as fine quality of rice,but also reduces the efficiency of mechanized rice harvesting.This paper reviewed the lodging types of rice,the relationships of lodging with root morphology,culm morphology,culm anatomical structure and chemical composition.Furthermore,the lodging resistance pathways in rice were put forward from four aspects:breeding resistant varieties,optimizing cultivation methods,strengthening field management and applying chemical control technology,and finally the summary and prospects were made.
