水氮互作对水稻产量形成的影响研究进展

Research Progress on Effects of Interactions between Water and Nitrogen on Yield Formation in Rice

协同利用水分和氮素这两个相互促进、相互制约的因子是提高作物产量与水氮利用效率的重要途径。本文从水氮互作的效应、水氮互作对水稻产量形成的影响以及高产高效栽培技术等方面进行了综述,并总结了存在的问题,提出了研究展望,以期为水稻高产、优质、高效栽培提供理论参考。

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.
