| 摘 要： | 保护性耕作以少耕、免耕、残茬覆盖为主要方式,具有保持水土、改变土壤理化性状、改善生态环境等优点。回顾了保护性耕作的发展过程,介绍了它的优、缺点,对国内外关于保护性耕作的生态效应研究进展从保护性耕作与水土保持,保护性耕作与土壤的理化性状,保护性耕作与土壤微生物区系、土壤酶活性和土壤动物,保护性耕作对土壤中碳储量的影响及对大气中CO2的贡献等4个方面进行了概括和分析。最后,讨论了我国保护性耕作的发展前景。

| Abstract: | The fundamental modes of conservative tillage are little tillage,no-tillage,and the remnant stubble coverage.It could maintain the water and soil,change the physical and chemical properties of soil,improve ecological environment,etc.The developing process of conservative tillage was reviewed;the advantages and disadvantages were also introduced in this article.The domestic and international research progresses in ecological effects of conservative tillage were summarized and analyzed as follows:the water and soil conservation;the physical and chemical properties of the soil;microflora and enzyme activities;the storage of the carbon in the soil and the emission of CO_2,etc.Finally,the developing prospects of conservative tillage in China were also discussed. |
