植物对氮磷元素吸收利用的生理生态学过程研究进展

Advances in Research of Physiological and Ecological Process of Nitrogen and Phosphorus Absorption and Utilization in Plant

氮磷元素是限制植物生长的关键因子,其存在形式多样,相互转化方式复杂,其中全球氮循环和磷循环在整个生态系统的物质循环中占据重要地位。本研究从氮磷元素的存在形式及其相互转化方式、植物对氮磷元素的吸收利用和转运过程及其影响因素、植物对氮磷元素变化的响应过程与机理等方面,总结了植物对氮磷元素吸收利用的生理生态学过程,并对目前研究中存在的问题和今后的研究方向进行了展望,以期为进一步开展植物营养生理生态学研究提供科学依据。

Nitrogen and phosphorus are the key factors limiting plant growth. Their existence forms are varied with intricated transformation modes. Nitrogen and phosphorus cycles are dominant in the matter cycle of the whole ecological system. In this paper, the physiological and ecological process of nitrogen and phosphorus absorption and utilization in plant were summerized from the existence forms and transformation modes, the absorption and transportion process and influencing factors, the plant response to nitrogen and phosphorus change and the mechanism. And then the present problems were analyzed, and the outlook of research direction in future was put forward. It was expected to provide scientific references for further research on physiology and ecology of plant nutrition.
