Abstract: The water crisis is threatening rice sustainability and food security in the world. Agricultural scientists have developed a variety of watersaving irrigation techniques and production systems in order to deal with water shortages meanwhile to increase food production. This paper reviewed dominant watersaving irrigation techniques applied in transplanted rice production, summarized their physiological and biochemical mechanism for  rice growth, hormones, and activities of key enzymes involved in sucrosetostarch conversion. The problems existed in watersaving irrigation techniques for highyielding and highefficiency of rice and research prospects were put forward and discussed.

Key words: rice, watersaving irrigation, high yield and high efficiency, physiological and biochemical mechanism
