Abstract: The shortage of water resource seriously limits the development of agriculture especially in rice production. Non-flooded cultivation of rice is an important innovation in rice production and has great significance in developing water-saving agriculture and ensuring food security in China. This paper surveyed the characteristics of grain yield and quality of rice under non-flooded cultivation, analyzed their reasons from the aspects of photosynthesis, mater production and translocation, root activity, grain filling and its hormonal and enzymatic mechanisms, and soil nutrition, and discussed the problems and countermeasures in developing non-flooded cultivation of rice.
