将木霉菌株Ｔ８８与７种常见的林果病原真菌进行平板对峙培养及显微观察，结果表明木霉菌株Ｔ８８对立枯丝核菌Ｒｈｉｚｏｃｔｏｎｉａｓｏｌａｎｉ等供试的７种病原真菌都有明显的拮抗作用，可观察到Ｔ８８对病原菌菌丝的缠绕、使细胞质变稀薄、菌丝消解或穿透等现象，以及对齐整小核菌Ｓｃｌｅｒｏｔｉｕｍｒｏｌｆｓｉ的菌核的重寄生作用，使其发生腐烂，并抑制了白绢病菌菌核的萌发。 Trichoderma strain T88 and seven kinds of common fruit pathogenic fungi plate confrontation culture and microscopic observations showed that Trichoderma strain T88 Rhizoctonia solani Rhizoctoniasolani and other tested seven kinds of pathogenic fungi have obvious antagonism, T88 can be observed on the pathogen hyphae winding, the thinning of the cytoplasm, mycelium digestion or penetration phenomenon, and the alignment of Sclerotium rolfsi Sclerotium rolfsi sclerotinia effect, make it rot and inhibit the white silk Germination of bacteria sclerotia.
