The mount of germ and fungus quantity in soil are remarkably increased for the continuous cropping about 5 years, puts the trichobacteria quantity always change tendency to reduce;The edaphon total quantity, the bacterium quantity change reduces generally above the continuous cropping 5 years and below 5 years (including 5 years) the change are not obvious;In the nitrogen physiology group by ammoniates the bacterium primarily and the quantity changes are not very big;The nitrifying bacteria quantity is lower than the comparison (non- continuous cropping), the quantity of denitrifying bacteria is opposite;The alkalinity phosphatase, the urease, invertin activeness have a closed relations with the continuous cropping when it will increase less than 5 years or decrease in more than 5 years. The relation between catalase activeness and the continuous cropping is not very big. The reduction of the invertin activeness, the alkalinity phosphatase, urease activeness have slightly elevates, catalase activeness have no the regular changes.

表现为连作条件下土壤真菌数量显著增大，放线菌数量总的变化趋势降低；土壤微生物总量、细菌数量变化在连作5年以上普遍降低，5年以下(包括5年)则变化差异不明显；氮素生理群中以氨化细菌为主，但数量变化不大；硝化细菌数量低于对照组，反硝化细菌数量则相反：多酚氧化酶、转化酶活性在5年之前逐渐上升，5年之后逐渐下降，，脲酶活性随着连作年限增加持续上升，过氧化氢酶活性、碱性磷酸酶活性变化无规律。

The number of heterotrophic bacteria and nitrifying bacteria increased with the time of the hydraulic retention time, contrary to the nitrobacter.
