摘　　要：从山西省蟒河自然保护区土样中分离得到拮抗链霉菌—MH4菌株。它对棉花枯萎病菌[FusariumoxysporumSchl.F.sp.vasinfectum(Atk.)Synder and Hansen]、棉花立枯病菌(Rhizctonia solaniKünn)、棉花黄萎病菌(Verticillium dahliaeKelb)等10多种植物病原真菌抑菌效果明显[1]。将其配制成生物制剂—可湿性粉剂制剂(以下简称生物制剂4号)进行室内棉花试验、抑菌试验和药敏试验。日光温室试验及田间试验均显示出对棉花枯萎病菌[F.oxysporumSchl.F.sp.vasinfectum(Atk.)Synder and Hansen]、棉花黄萎病菌(V.dahliaeKelb)、棉花立枯病菌(R.solaniKünn)、黄瓜枯萎病菌(F.oxysporumSchl.f.sp.CucumerimumOwen)、西瓜枯萎病菌[F.oxysporumf.sp.niveum(E.F.Sm)Synder et Hensen]及棉苗根病有较好的防治效果,特别是用在瓜类枯萎菌上防治效果较为突出。An antagonistic Streptomyces strain MH4 was isolated from soil of Manghe Natural Reserve in Shanxi Province. It had distinctively inhibition against Fusarium oxysporuzn Schl f. sp. vasinfectum, Rhizoctonia solani, Verticillium dahliae, and other some ten plant pathogenic fungi. Tests on cotton, antimicrobial, and drug sensitivity with bio-preparation-wet-able powder made of the strain （bio-preparation No 4 for short thereafter） were carried out in green house. The results showed that it has fairly good control against F. oxysporum Schl f. sp. vasinfecturn, R . solani , V. dahliae , F. oxysporum Schl f. sp. cucumerimum , F. oxysporum Schl f. sp. niveum , and cotton seedling diseases. Especially the control on fusarium wilt cucurbit crops was very notable.
