摘要
自然界各种微生物生活在一起,成为复杂的群落。它们相互促进、制约,构成生物体的生态平衡。在森林病害防治中,利用益菌控制病菌的生存和活动,达到生物防治的目的。为了寻求这一新途径,在1982—1984年,对4种杨树重要病害进行了生物防治探索,从筛选和防病上作了研究。
Biological control of poplar diseases is a preliminary study in China.The results of trials were as follows: the control effects of Pseudomonas fluoracens, Bacillus subtilis, B. pumilus and Streptomyces griseus against Cytospora chrysosperma and Gloesporium tremulae were promising. The control effects of Trichoderma sp. (42), T. viride and T. sp. (11) against Dothiorella gregaria and C. chrysosperma were promising, too. The control effects of B. subtilis, B. pumilus, Pseudomonas sp. (M), T. sp. (42), T. viride, T. sp. (11) against Marssonina brunnea were no striker.Using beneficial bacteria against spores of the tested poplar pathogens, the author found there were lysis and fungistatic action. Using beneficial fungi against the above mentioned pathogens there were no fungistatic action.
