| 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1 V∶200 V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7.4×106 cfu·g-1增加到16.75×106 cfu·g-1，增加了126.35%。

| Abstract: | Both fermentation broth and solid state fermentation of Streptomyces roseoflavus Menmyco-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%. |
