| 摘 要： | 通过微营养培养分离拮抗菌和淀粉发酵法分离营养竞争性菌株，共分离到１３９个菌株，其中拮抗性菌株１２３个（１１８个细菌，５个放线菌）营养，竞争性菌株１６个（３个酵母菌，１３个细菌）。通过离体试验，３０个拮抗菌仍表现出明显的防治效果，占总数的２１．６％。经温室试验测定，９个菌株防治小麦赤霉病效果达７０％以上，占总数的６．５％。经大田小区只有ＹＮ１、ＧＪ６、Ｙ－１２等３个菌株分别表现出６７．６％、６４．９

| Abstract: | 139 strains were isolated by methods of micronutrition for antagonistic microorganisms and by starch fermetation for competitive microorganisms, among which 123 were antagonistic strains (118 bacteria and 5 actinomyces) and 16 were nutritionally competitive strains (3 yeasts and 13 bacteria). Tests in vitro showed that 30 antagonistic strains (21. 6% of the total isolates) had obvious control effects. Among them 9 strains gave more than 70% control effect on wheat scab in the greenhouse. Three strains, YN1, GJ6 and Y -12, which took 2. 2 percent of the total, showed 67. 6%, 64. 9% and 56. 8% control effects on wheat scab in field trials, respectively. |
