| 摘 要： | 从冬闲覆盖作物对土壤有机碳的固定及覆盖作物对主作物产量的影响等方面对国内外有关覆盖作物环境改良机理的最新研究结果进行了总结分析。认为,长期轮作覆盖作物可以增加土壤有机碳,提高微生物的活性,而且对主作物的产量提高有不同程度的促进作用。

| Abstract: | Soil organic carbon(SOC) loss often takes place in conventional-tillage,but the adoption of conversation tillage may reduce SOC loss,increase the content of surface soil organic matter.It is important to study the effect of cover crop on carbon sequestration potential in cropland.This paper summarized the internal and external researches on the cover crop effect on SOC.The result indicated that cover crop rotation may enhance SOC,soil microbial biomass C,the activity of soil microbe,and increase the main crop yield. |

| Keywords: | cover crop soil organic carbon crop yield |
