摘　　要：抑制菌丝生长速率法生测结果表明:木霉L24菌株水溶性代谢物对供试菌株均有较好的抑制作用,抑制率均在50%以上;菌丝互作试验结果表明,木霉L24菌株菌丝对茄丝核菌菌丝有重寄生作用;盆栽试验结果表明,木霉L24菌株对小白菜和萝卜幼苗生长均有很好的促进作用,促进率分别为215.1%和166.3%;大田试验结果表明,木霉L24菌株对油菜苗期的生长也具有良好的促进作用。The results of mycelium growth rate showed that water-soluble metabolic products of Trichoderm L24 strain were efficient to the tested fungi, the inhibition rate of that were all above 50 %. The results of mycelium interaction showed that Trichoderm L24 strain reparasited on Cunninghamella echinulata. The result of pot test indicated that Trichoclerm L24 strain was good for the growth to Raphanua sivus L. and B. chinensis var. communis ,and the promotion rate were 215.1% and 166.3 %, respectively. The result of field test indicated that Trichoderm L24 strain was good for the growth to B. chinensis vat. oleifera.
