摘要
从石河子地区棉花根际土壤中采集土样３６份，经室内分离、纯化后获得生长数量占优势的菌株各１０８个（细菌、放线菌、霉菌）共计３２４个，对棉花立枯病的病原菌进行平板双培养法拮抗测定，共筛选出１００个有拮抗活性的菌株，对之进行筛选、比较后，选出拮抗活性较强的９个菌株进行盆栽试验。
soil samples were collected from rhizosphere of cotton in shinhezi locations 324 strains(Bacteria,Actinomycetes,Mold)were obtained by isolation and purification Their antagonistic activity against cotton Rhizoctonia solani were tested in plate Of the 324 strins,100 were found antagonistic As a result,7 strong antagonistic strains were selected from 100 antagonistic strains,by size of antagonistic activity in pot tests
