玉米高效利用氮素的生理机制研究进展

Research Advances of Physiological Mechanism for Efficient Nitrogen Utilization in Maize

基于经济效益和环境保护的考虑,玉米的氮效率引起了许多科技工作者的重视。玉米的氮效率可以分解为吸收效率和利用效率,近几年来,国内外对玉米吸收和利用氮素效率的评价方法和生理机制进行了较深入的研究。本文对这一领域的研究进展进行了综述,并提出了该领域今后的重点研究方向。

Concerning about the economic benefits and environment protection, the nitrogen efficiency of maize, which includes nitrogen uptake efficiency and nitrogen utilization efficiency, have been attached by many researchers. Some evaluate ways and physiological mechanism of efficient nitrogen uptake and utilization in maize have been explored at home and abroad for years. In this paper, some advancements in this area were reviewed, and some key aspects in the area for future study were also put forth.
