探讨9个木霉菌株的生长与产孢特性，并通过对峙培养法，测定了9个木霉菌菌株对橡胶树褐根病菌的拮抗作用。结果表明， HCS、DJ1和 ACCC31757生长速度最快，平均生长速度在4.5 cm · d－1以上， ACCC30536平均生长速度最慢，只有1.5 cm · d－1；9株木霉菌对橡胶树褐根病菌的拮抗作用差异较大，其中有3株木霉菌对橡胶树褐根病病原菌具有显著的拮抗作用，在第8 d ， ACCC31642和 HCS对褐根病病原菌的抑制率达到100％， ACCC31639对褐根病病原菌的抑制率达到93.33％。

In this study ,the characteristics of growth and sporulation were observed in 9 strains of Trichoderma , and the antagonistic effects of them on the soil‐borne Phellinus noxius in Hevea brasiliensis were studied with confrontation culture in vitro .The results showed that HCS ,DJ1 and ACCC31757 strain grew faster ,the average growth rate of which were over 4.5 cm per day ;ACCC30536 strain grew the most slowly ,the growth rate was only 1.5 cm per day . Nine strains demonstrated significant difference in their capacity of inhibiting the grow th of Phellinus noxius ,and three strains of which could effectively inhibit the growth of Phellinus noxius in Hevea brasiliensis .In the eighth day ,the inhibition rate of ACCC31642 and HCS for brown root disease pathogen reached 100% ,and ACCC31639 reached 93.33% .
