| 摘 要： | 本文强调了养分再循环在建立我国持久农业中的实际意义。养分再循环潜力巨大，可提供纯养分达3514万吨，相当于我国1989年化肥总产量的1.96倍。养分再循环需要解决一系列技术问题。笔者认为：如何建立我国在养分再循环基础上的施肥制度和防止养分再循环可能出现的环境问题是两个重点问题。笔者提出了这两方面研究工作的例子。

| Abstract: | The nutrients recycling technology in agriculture played and will play great role in construction of modern and sustainable agriculture system in China. Estimation of potential of recycling nutrients in China in 1989 was made which amounted to 3.5 millon ton, about twice as much as the output of chemical fertilizers in the same year. There are several problems which should be solved in nutrients recycling. One is the development of fertilization system based on nutrients recycling. Another is to solver the environment problems with organic manure application. The authors gave two research examples to show how to solve these problems in this respect. |
