摘　　要：氮肥在我国水稻种植中投入量巨大,但氮肥利用效率却远低于世界平均水平。这不仅消耗高额的成本,而且破坏生态。因此,选育氮高效水稻具有重要意义。主要针对高效氮水稻的氮素吸收利用效率、生理机制、提高水稻氮高效吸收的方法及水稻氮高效基因的挖掘等方面进行了综述,以期为今后更好地开展氮高效水稻农业育种研究工作提供科学依据。The huge amount of nitrogen fertilizer invested in rice cultivation not only consumes huge costs,but also destroys the ecological environment.According to statistics,the utilization efficiency of nitrogen fertilizer in agriculture in China is much lower than the world average.Therefore,it is meaningful to breed nitrogen-efficient rice.In this paper,the nitrogen uptake and utilization efficiency of high-efficiency nitrogen rice,physiological mechanisms,methods for improving high-efficiency nitrogen uptake in rice and the mining of rice nitrogen-efficient genes in rice were reviewed,in order to provide scientific basis for further research on rice nitrogen-efficient breeding.
