摘　　要：氮素是作物生产上施用量最多的肥料,氮肥施用量过多是我国水稻生产上的突出问题。介绍了氮肥施用方法对水稻产量和氮肥利用效率的影响及其生物学基础,并对实现水稻高产与氮肥高效利用提出了建议。Nitrogen（N） is the largest amount of application fertilizer in crop production.Overuse of N-fertilizer is a serious problem in rice production in China.Here reviewed the effects of N application techniques on grain yield and N use efficiency as well as their biological basis,and put forward some suggestions about how to realize higher grain yield and higher N use efficiency in rice.

关 键 词：水稻 氮肥 产量 氮利用率
