论文部分内容阅读
在《吕氏春秋·上农》等四篇文献中有许多关于尊重和利用农时的论述;有关于植物生长与土壤肥力和环境的关系的论述;有土壤耕作和作物种植制度的论述。这些论述,在今天看来也是基本正确的。本文拟就这几方面加以介绍。
There are many excerpts in the four literatures “Spring, Autumn, and Shangnong” about respecting and using farm time; expositions on the relationship between plant growth and soil fertility and the environment; and discussion on the system of soil cultivation and crop cultivation. These expositions are also fundamentally correct today. This article intends to introduce these aspects.
