提高小麦氮肥利用率的生理生化机制及其研究进展

Advances in Physiological and Biochemical Mechanism of Improving Nitrogen Use Efficiency for Wheat

基于经济效益和环境保护的考虑,如何提高小麦的氮肥利用率成为当今植物营养学科研究的重点。提高氮肥利用率的农学管理途径很多,综述了提高小麦氮肥利用率的生理生化机制及其研究进展,讨论了如何通过氮高效品种的开发来提高小麦氮肥利用率,并在此基础上对该领域未来的研究重点进行了展望。

In view of economic benefit and environmental protection, more and more attention has been paid to now to improve nitrogen use efficiency of wheat in the plant nutrition subject in recent years. There are many agronomic practices to improve the nitrogen use efficiency. This paper reviews the research progress of physiological and biochemical mechanism of wheat to improve nitrogen use efficiency, and discusses how to improve nitrogen use efficiency of wheat through developing the nitrogen high efficient varieties, and on this basis the research emphases in the field are prospected in the future.
