摘要
稳定性核素示踪是现代农业研究中一门新兴技术。稳定性核素15N作为一种有效手段在农业施肥研究、氮素循环研究中发挥着极为重要的作用。本文介绍了15N的相关概念,列举了20世纪80年代以来15N在氮肥研究、氮素转化研究以及农业环境保护中的应用进展,阐明了应用15N的新技术已解决的问题,以及将要解决的问题,并展望了性核素示踪技术的应用前景。
Stable nuclide tracer is a new method in modern agricultural research, and it also plays a very important role in the research of nitrogen fertilizer and nitrogen cycling. In this paper, the concept related to ^15N application were introduced and interpreted, and the studies on N fertilizer research, N cycling and agricultural environment protection since 1980 were reviewed in detail. The problems, those ^15N technique has been resolved and will be resolved, were presented.
