摘要
为明确棘孢木霉的抑菌谱及其制备的生物炭木霉菌肥对北苍术根腐病的防治效果,采用平板对峙法筛选出抑菌谱最广的菌株后,采用田间随机区组试验测定了木霉菌肥对北苍术根腐病的田间防治效果。结果表明:Shi-1-8的抑菌谱最广,对串珠镰孢菌等8种病原菌的抑菌率均高于80%。经过6 d发酵分生孢子为1.48×10^(9)个·g^(-1)。木霉菌肥对北苍术根腐病的田间防治效果达到73.32%。由此表明,木霉菌肥可用于防治北苍术根腐病。
The widest inhibition effect of Trichoderma asperellum different strains to pathogens were screened with plate confrontation to clarify the antibacterial spectrum of T.Asperellum and control effect on Atractylodes lanceolata root rot with random block in the field of Trichoderma fertilizer that was made by T.Asperellum.The result showed that the widest inhibition spectrum to Fusarium moniliforme and other 7 kinds of pathogens was Shi-1-8,and their inhibition rates were higher than 80%.The conidia quantities of Shi-1-8 reached 1.48×10^(9)·g^(-1)after 6 days of fermentation.The control effect of Trichoderma fertilizer on A.Lanceolate root rot in the field was 73.32%,marking that Trichoderma fertilizer could be used to control root rot of A.Lanceolata.
