    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,而且变革了传统水稻的种植方式,显著降低水稻生产的劳动强度及对环境产生的负面影响。本文结合前人和本团队近年来的工作,论述了我国节水抗旱稻发展现状、前景,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,以期为节水抗旱稻的推广和应用提供参考与指导。

    Abstract:

    Water-saving and drought-resistant rice (WDR) is a new type of rice varieties combining strong water-saving capacity and drought resistance with high yield potential and quality. The development of WDR not only breaks through the limitation of water resources to expand plantation range and area of rice and thus helps to ensure food security, but also significantly reduces the labor intensity and the negative impact on environment of rice production by reforming plantation methods. In this paper, the current situation, development prospect and main problems to be resolved in WDR production were discussed based on the previous studies and our investigations. Moreover, the future research work needed to be strengthened was proposed. The main purpose of this paper is to provide a guideline for the future study and development of WDR.
