摘　　要：节水抗旱稻是一类新型水稻品种,集高产、优质和节水抗旱于一体。发展节水抗旱稻不仅可降低水稻生产对水资源的依赖,扩大水稻种植范围和面积,有利于保障粮食安全,还变革了传统水稻的种植方式,可显著降低水稻生产的劳动强度以及对环境的负面影响,促进资源节约型和环境友好型“两型”农业的发展。本文论述了我国节水抗旱稻发展现状、优势,分析了可能制约节水抗旱稻发展的主要因素,提出了节水抗旱稻未来的主要研究方向,以期为节水抗旱稻扩大推广应用提供参考。Water-saving and drought-resistant rice(WDR)is a novel type of rice variety that integrates high-yield,high-quality,water-saving and drought-resistance.The development of WDR can not only reduce the dependence of rice production on water resources,expand the scope and area of rice cultivation,and help ensure food security,but also changes the traditional rice planting methods and significantly reduces the labor intensity of rice production and the negative impact on the environment.Therefore,the development of WDR is conducive to the promotion of“two-oriented”agriculture,i.e.,resource-conserving and environment-friendly agriculture.This article discusses the development status,advantages and main problems to be resolved of WDR in China.The main factors that may restrict the development of WDR were analyzed.The research directions of WDR needed to be strengthened in the future were proposed.It will provide a guideline for the future study and development of WDR in China.
