摘　　要：利用玫瑰黄链霉菌Men-myco-93-63菌株的固、液体发酵物防治设施番茄和黄瓜根结线虫,研究其对根结线虫的防效以及施用生防菌对土壤微生物区系的影响。结果表明:Men-myco-93-63菌株固体发酵物1V∶200V对黄瓜和番茄根结线虫病的防效分别达到了65.62%和57.69%;施用生防菌使得植株根际土壤中细菌数量增加了19.57%,放线菌数量增加了316.67%,真菌数量降低了28.57%,以上3种可培养微生物总量由7.4×106cfu·g-1增加到16.75×106cfu·g-1,增加了126.35%。Both fermentation broth and solid state fermentation of Streptomyces roseoflavus Men-myco-93-63 isolate were used for controlling tomato and cucumber root-knot nematode. The control efficacy and its effect on soil microbiota were studied. The results showed that the control efficacy of the treatment on cucumber and tomato by 1 V∶200 V solid state fermentation of Men-myco-93-63 were 65.62% and 57.69%,respectively. The application of bio-agents has increased the number of bacteria and actinomyces in soil by 19.57% and 316.67%, respectively,while the number of fungi reduced by 28.57%. The three kinds of the cultivable soil microorganism raised from 7.40×106 cfu·g-1 to 16.75×106 cfu·g-1,amount to 126.35%.
