摘　　要：水稻(Oryza sativa)根系在氮素吸收和利用过程中起重要作用。本文介绍了水稻氮素吸收和同化过程及根系特征,综述了水稻根系特征对氮素吸收的影响和氮素供应对根系特征的调控,从氮肥吸收利用、根系特征与氮肥互作的角度讨论了今后水稻根系研究的发展方向,以期为提高水稻氮素吸收利用效率提供理论基础,为氮素高效吸收利用水稻新品种选育工作提供新思路。The rice root system plays an important role in the nitrogen uptake and utilization.In this article,we introduced the process of nitrogen uptake and assimilation and root characteristics in rice,and summarized the effect of root characteristics on nitrogen absorption and the regulation of nitrogen supply on root characteristics.The further research directions were discussed in terms of nitrogen uptake and utilization,root characteristics and nitrogen fertilizer interaction.This review may provide theoretical consideration for improving nitrogen uptake and utilization efficiency,and provide new insights for developing rice cultivars with high nitrogen efficiency.
