摘要
报道了对寄生于天麻依存蜜环菌（Ａｒｍｉｌａｒｉｅｌａｍｅｌａ）上的一种木霉（Ｔｒｉｃｈｏｄｅｒｍａ）的鉴定和生物学特性研究，并讨论了防治措施。鉴定结果：该种木霉是绿色木霉（Ｔｖｉｒｉｄｅ）。它对蜜环菌和玉米纹枯病菌（ＲｈｉｚｏｃｔｏｎｉａｓｏｌａｎｉａＡＧ－１－ＩＡ）的主要作用是缠绕、附着在菌丝（索）上寄生。它有拮抗作用，但不产生抑菌圈，对玉米纹枯病菌菌丝抑制率为７４％。最适生长温度为２８～３２℃，可以采用避免窖场连作、人工培菌、高山降湿栽培等措施防治。
A species of Trichoderma sp was isolated from Armillariella mellea depended on by Gastrodia elata and was identified as Trichoderma viride in terms of its morphology and biological characteristica. It could parasitize Armillariella mella and Rhizoctonia solani AG-1-IA by winding round or adhering to their hypha or rhizomorphs. It had an antagonism without inbibitory ring and could inbibit the growth of R solani AG-1-IA by 74%. Its optimum growth temperature is 28～32 ℃. Some control methods were discussed.
