现代农业的一个主要挑战是减少化肥的过度投入，同时在不影响产量的情况下提高粮食质量。实现这一目标的一种方法是通过操纵来自衰老植物器官的氮再循环，特别是氮再动员来改善植物氮经济。本文综述了氮素再动员效率（NRE）对全球氮素利用效率（NUE）的贡献，以及NRE的测定方法。氮再动员的生理，代谢和遗传方面的全面检查。
A major challenge of modern agriculture is to reduce the excessive input of fertilisers and, at the same time, to improve grain quality without affecting yield. One way to achieve this goal is to improve plant nitrogen economy through manipulating nitrogen recycling, and especially nitrogen remobilisation, from senescing plant organs. In this review, the contribution of nitrogen remobilisation efficiency (NRE) to global nitrogen use efficiency (NUE), and tools dedicated to the determination of NRE are described. An overall examination of the physiological, metabolic and genetic aspects of nitrogen remobilisation is presented.
