摘要：

从棉株根围土壤中分离到２００多株土壤微生物。通过土壤微生物－棉枯萎病菌平板对峙培养，筛选出抑菌效果较好的７个菌株，即绿色木霉Ｔ－０３，芽孢杆菌Ｂ－０１、Ｂ－０３，放线菌Ａ－０３、Ａ－０６、Ａ－０７、Ａ－１９。用上述７个土壤拮抗菌进行棉花枯萎病田间小区防效试验的结果表明，Ｔ－０３对棉花枯萎病的防效最高，达７６．５％；４个放线菌株的防病效果在６０．５％～６５．１％之间，其中Ａ－０３对棉花出苗有一定抑制作用；Ｂ－０１、Ｂ－０３的防效分别是３６．４％和５４．０％。

Abstract: More than 200 strains of soil-microbes were isolated from cotton rhizosphere soil. Based on soil-microbes-pathogen (Fusarium oxysporum f.sp.vasinfectum) pairing culture, seven strains of soil antagonistic microbes were selected, namely Trichoderma viride (T-03), Bacillus spp.(B-01,B-03) and Actinomyces spp.(A-03, A-06, A-07, A-19). The above-mentioned soil-antagonistic strains were tested for controlling cotton fusarium wilt disease in the field. The results showed that T-03 was the best, the control effect was 76.5%. The control effect of the four strains of Actinomyces, A-03,A-06,A-07 and A-19 was 60.5% to 65.1%, and Bacillus B-01 and B-03 was 36.4% and 54.0% respectively. A-03 was found to have inhibiting action on cotton emergence.
