植物对氮素吸收利用的研究进展

摘要： 本文对近年来植物对氮素吸收的研究进展进行了详细的阐述，从氮素对植物生长发育的影响、植物对氮素利用的生理机制和分子机制三个方面进行了总结，旨在为植物营养育种提供一定的理论依据，从而实现提高植物氮素利用效率的目的。

Advances on Plants’ Nitrogen Assimilation and Utilization

Recent years with the aggravation of the pollution caused by the over-application of nitrogen, improving the nitrogen use efficiency and reduce the eco-system pollution has become a hot research goal. The paper has made detailed summarization of the nitrogen utilization of plants from the following three parts： the effect of nitrogen on plants growth and development, the physiological and molecular mechanism of the nitrogen utilization. With the rapid development of plant genetic engineering improving the nitrogen use efficiency by gene engineering has become the orientation for the future plant nutrition molecular breeding and I have put forward my personal views on the key research about the plant nitrogen nutrition in order to provide theoretic guidance for the crop nutritional breeding and improve its nitrogen utilization efficiency.
