摘　　要：水稻氮代谢决定了氮素的吸收、转运和同化,最终影响产量形成。外施水杨酸(SA)对植物氮代谢和氮肥利用效率发挥积极作用,但对其作用方式及SA与氮代谢之间的关系知之甚少,尤其缺乏分子水平的解析。本文从氮素的吸收形式、生理生化代谢及内源SA含量变化等方面对水稻氮素吸收利用的研究进行了综述,旨在从氮代谢角度阐释植株对氮素的运移特性、SA的调节效应及可能的作用方式,为发展节肥增效栽培和环境友好型稻作提供新思路。The nitrogen metabolism in rice determines the efficiency of nitrogen uptake, transport, and assimilation,which also affects the grain yield formation. In this paper, the nitrogen uptake and utilization in rice is described from the aspects of nitrogen uptake forms, physiological metabolism processes and the content variation of endogenous salicylic acid. To explain plants nitrogen transport, the regulation effect of salicylic acid and its possible action mode based on nitrogen metabolism. This review will provide novel ideas for rice cultivation under decreased fertilizer application and increased efficiency and environment-friendly rice cropping in agricultural production.
