摘　　要：测定了 2 6株链霉菌对番茄早疫病菌、番茄灰霉病菌、甘蓝黑腐病菌、白菜软腐病菌和大肠杆菌这 5种病原菌的抑菌作用。结果发现 :在供试的 2 6株链霉菌中 ,菌株Men -myco - 93- 6 3、6 3、Mycostop、GS - 93- 10、GS - 93 - 3和GS - 93- 2 3对番茄早疫病菌 ,菌株 15、6 3、GS - 93- 10、93和Mycostop对番茄灰霉病菌 ,菌株 32、GS - 93- 2、GS - 93- 3、GS - 93 - 2 3和 93对甘蓝黑腐病菌 ,菌株GS - 93- 3、GS - 93- 2 31、GS - 93- 10和Men -myco - 93- 38对大肠杆菌抑菌作用较强 ,它们的抑菌活性明显高于对照化学药剂 ,白菜软腐病菌无抑菌活性强的菌株 ,只有菌株GS - 93 -10和GS - 93- 2Antagonistic activity of 26 strains of Streptomyces spp. was tested against several important pathogens including Alternaria solani of tomato, Botrytis cinerea of tomato, Xanthomonas campestris of cabbage, Erwinia carotovora of Chinese cabbage and Escherichia coli . Of the 26 strains, Men-myco-93-63,63,Mycostop,GS-93-10,GS-93-3 and GS-93-23 were found to have strong antagonistic activity against Alternaria solani ;15,63,GS-93-10,93 and Mycostop against Botrytis cinerea ; 32,GS-93-2,GS-93-3,GS-93-23 and 93 against Xanthomonas campestris ; GS-93-3,GS-93-231,GS-93-10 and Men-myco-93-38 against Escherichia coli .
