Abstract: Some advances on physiological mechanism of efficient nitrogen uptake and utilization in rice were reviewed. Heredity potential and approaches for efficient nitrogen utilization and the influence of farm resource management to nitrogen uptake were summarized. Some topics were brought forward for the time to come.

Key words: rice, nitrogen utilization efficiency, nitrogen uptake efficiency, physiological mechanism, efficient approach

摘要: 阐述了水稻高效吸收和利用氮素的生理机制,分析了水稻高效利用氮素的遗传潜力和改良途径以及农田资源管理技术对氮素效率的影响,并提出了需要研究的重要课题。
