Abstract: Soil biologic amendment (BSA)was applied to the cucumber continuous cropping to control soil2borne dis2 eases and reduce replant diseases of cucumber. The changes of soil microorganism population structure were discussed by different agent. The result showed that total population of cucumber rhizosphere microbes increased remarkably after ap2 plying soil amendment.Number of bacteria and actinomycetes had a drastic variation.Number of fungi increased slightly. The species and amount of the dominant species were changing,beneficial microbes such as Trichoderma and Penicillium were more.Dominant species in rhizosphere antagonism were stronger along with controlling effect increasing. Applying BSA could increase soil microbial diversity and adjust community structure of soil microbial,and had better ecological sta2 bility than fungicide.

Key words: Biological soil amendment, Cucumber, Replant diseases, Rhizosphere microbes
