摘　　要：作物地上部分生长与产量形成受根系的形态特点及其生理活动的显著影响。水稻作为农业第一用水大户,水资源短缺势必会严重影响到其生产的发展,干湿交替灌溉作为一种节水灌溉方式目前在水稻生产中应用较为广泛,然而有关干湿交替灌溉下水稻根系生长发育是如何响应的,其内在机制是什么均缺少系统分析和总结。为此,本文综述了干湿交替灌溉技术及水稻根系形态与生理特征,分析了根系生长发育对干湿交替灌溉的响应机理,并提出了目前存在的问题和对未来研究的展望。The morphological and physiological characteristics of crop root system play an important role in the growth and development of aboveground part and the formation of yield.Rice is the largest water user in agriculture,and the shortage of water resources is bound to seriously affect the development of rice production.As a water-saving irrigation method,alternate wetting and drying irrigation technology is widely used in rice production at present.However,there is a lack of systematic analysis and summary on how rice root growth and development respond to alternate wetting and drying irrigation,and what its internal mechanism is.Therefore,this paper reviewed the technology of alternate irrigation and the morphological and physiological characteristics of rice roots,analyzed the response mechanism of root growth and development to dry and wet alternating irrigation,and put forward the existing problems and prospects for future research.
