Abstract:

Synergistic use of water and nitrogen, which are mutual promotion and mutual restriction, is an important approach to increase crop yield and water and nitrogen use efficiency. In this paper, the effects of water-nitrogen interaction, influence of water-nitrogen interaction on yield formation, and the cultivation techniques of high yield and high efficiency in rice were summarized, and current problems and future research prospects were analyzed. These would provide theoretical references for high-yield, good quality and high-efficiency cultivation of rice.

Key words: rice, water-nitrogen interaction, grain yield
