| 摘 要： | 多数文献报道我国氮肥利用率低，旨在总结我国氮肥利用率低的原因。从氮肥利用率的概念和测定方法入手，对15N示踪法测定氮肥利用率的方法及概念做详尽综述。讨论了氮肥利用率作为一个重要的施肥参数，测定中必需的稳定环境条件和土壤氮素库容稳定的必要条件，还阐述了土壤氮肥利用率概念的含义。

| Abstract: | The average apparent recovery efficiency of applied nitrogen （REN） was low in Chinese food crops （35%） compare with developed countries （50%）. The article introduced the concept and measurement methods of REN by 15N tracer. The REN results from document search had been analyzed and evaluated. Some problems had been put forward in REN calculation. The way to improve REN calculation had been recommended. |
