土壤退化

另外，在大棚蔬菜生长过程中CO2亏缺、土壤退化、土传病害、植物产量和品质的下降等连作障碍问题已成为影响大棚蔬菜产量和品质提高的关键因素。

Besides , the deficiency of CO2 , soil degradation , soil-borne diseases and continuous cropping obstacles have become the important factors affecting the quality and yield of the vegetables in the greenhouse .

土壤退化以后，土壤化学成分包括土壤有机碳、N、P和土壤微量元素等成分都出现了不同程度的变化，且发现这种理化特性的变化与土壤退化强度又密切的关系。

The chemical compositions of soil also varied correspondingly with the degradation of the soil ( including organic carbon , N , P and other micro-elements ) . The variation of the physical and chemical properties is closely correlative with the intensity of the soil degradation . 2 .

土壤退化指数（SDI）表明，稻-草轮作模式稻田土壤质量都有不同程度的提高，而常规稻作系统稻田土壤质量有轻微下降。

In addition , soil degeneration index ( SDI ) also suggested that , compared to the waster land in this study area , paddy field increased to varying degree under all rice-ryegrass rotation systems and decreased slightly under conventional cropping system in the present study .
