通过植物-土壤反馈试验，研究连作及轮作土壤微生物菌群对黄瓜幼苗生长和土壤酶活性的影响。结果表明，轮作土壤微生物处理黄瓜植株鲜质量、叶绿素含量、土壤中性磷酸酶、蔗糖酶活性显著高于连作土壤微生物处理；连作及轮作土壤微生物处理增加了黄瓜幼苗干质量、鲜质量、叶绿素含量及总叶面积，显著提高了土壤中性磷酸酶、蔗糖酶、脲酶活性。综上，连作及轮作土壤微生物菌群对黄瓜幼苗生长均产生正反馈作用，并且轮作土壤微生物的正反馈作用大于连作土壤微生物。

This paper studied the effects of microorganism population in continuous and rotated cropping on cucumber seedling growth and soil enzyme activity. The results showed that in rotated cropping microbial treatment,the fresh weight,chlorophyll content,the activities of neutral phosphatase and invertase of cucumber seedlings were significantly higher than that in continuous cropping microbial treatment. Both the continuous and rotated cropping microbial treatments had increased the fresh and dry weights,chlorophyll contents,total leaf area of cucumber seedling,and significantly increased the activities of soil neutral phosphatase,invertase, urease. Summing up the above,soil microorganism population in both cropping systems had a positive effect on the growth of cucumber seedling,and the positive effect on soil microorganism population in rotated cropping was stronger than that in continuous cropping.
