水稻氮素利用研究进展

The Research Progress of Nitrogen Utilization in Rice

介绍了目前国内水稻氮素利用概况,详细论述了水稻植株和土壤氮素吸收利用的研究进展,分析了氮素对植物生长发育的重要作用、氮素存在形态和损耗、植株与土壤对氮素吸收利用差异及水稻生产中氮素利用存在的问题,并结合水稻生产实际对如何提高氮肥利用效率做了初步探讨。

General situation of nitrogen utilization in rice at home,the research progress of nitrogen utilization in rice and soil were discussed in detail in the paper. The important role of nitrogen in plant growth and development ,the morphology and loss of nitrogen ,the differences of nitrogen utilization between plant and soil and the problems of nitrogen utilization in rice production were analyzed. A preliminary study on how to improve the nitrogen use efficiency binding rice production was carried out at last.
