摘　　要：The water shortage faced with rice production in China was comprehensively analyzed,and the seasonal as well as spatial and temporal differences were the factors limiting rice production,which would be a severe test for grain production safety.Therefore,solving strategies had been proposed from the following aspects：the improvement of irrigation practices was of significant effect on improving the high efficient utilization of water;the screening of drought resistance cultivars and upland rice cultivation could also greatly improve the ability of drought resistance;the combination of traditional breeding techniques with modern transgenic technology as well as the QTL analysis had made considerable progress on improving the soil moisture productive potential of rice from the perspective of genetics.The development of China＇s rice industry would face greater water scarcity in the future,but the conventional water-saving technologies could only reduce water consume to a certain extent,while the exploration and improvement of the water saving potential of wetland rice to give full play to the biological water-saving function would become the goal of agricultural development in China.综合分析了未来中国水稻生产面临的缺水问题,季节性以及时空地域的差别成为水稻生产的限制因子,这将使粮食生产安全面临严峻考验。作物研究学家从以下几个方面提出解决策略:灌溉措施的改良对于提高水分的高效利用有显著的作用;抗旱品种的筛选和旱作水稻栽培技术也可在很大程度上提高水稻抗旱节水能力;传统育种技术与现代转基因技术以及QTL分析的结合,对于从遗传学方面改善水稻自身的水分生产潜力取得了长足的进步。未来中国水稻产业的发展将会面临更大水资源匮乏问题,传统的节水技术在一定程度上只能起到缓解作用,而挖掘、改善水稻自身的节水潜力,发挥生物节水功能将成为未来中国农业发展的目标。
