氮肥能提高水稻产量已经是不争的事实，作为水稻最重要的营养元素，氮在水稻体内的吸收、转运及利用显得尤为重要。本文综述了氮肥在水稻体内的重要作用，结合最新研究成果对氮肥吸收和转运规律进行了整理，具体分析了铵态氮和硝态氮在水稻体内的同化和转运过程，也对氮肥吸收的限制因素进行了讨论，并对如何提高水稻氮肥利用效率提出展望，以期为氮肥的合理有效利用提供依据，也为水稻氮素营养研究提供理论基础。

Nitrogen fertilizer was applied to increase the yield of rice, which is an indisputable fact. As the most important nutrient element in rice, nitrogen plays an important role about its absorption, transportation and utilization of nutrient elements in rice. We introduced the significance of nitrogen fertilizer in rice in this review, combined with the latest research on nitrogen nutrition of rice, analyzed the absorption and assimilation process of ammonium and nitrate in rice plants. We also discussed the restriction factors of nitrogen use efficiency. Valuable outlook on how to improve nitrogen use efficiency of rice has been provided, and nitrogen fertilizer must be applied with a rational and efficient way. We also hope that this summary will offer a theoretical basis for reasonable application of nitrogen fertilizer and nutrition research on rice.
