| 摘 要： | 玉米对氮素营养利用存在基因型差异，利用玉米在形态，生理代谢上对氮素吸收、转运、利用等方面的遗传差异性进行定向育种，能够解决生产中遇到的氮素利用率下降、生产成本提高、经济效益递减，环境污染问题。本文综述了国内外玉米氮素营养方面的研究进展，为玉米高效生理机制的深入研究提供参考。

| Abstract: | The genetic difference of nitrogen utilization in maize existed. Directional breeding according to the genetic difference of nitrogen absorption, transportation and utilization in maize can improve nitrogen utilization, economical efficiency and environmen. This paper summed up the progress of nitrogen nutrition in maize and provided some references to investigate the physiological mechanism of high-nitrogen use efficiency. |
