68 strains were collected fiom different environments around Xingtai University and purified. 16 strains having antagonistics effect to Botrytis cinerea, which account for 23.5％ in total were obtained. Among them, 9 strains having great intensive repression to Botrytis cinerea were detected. According to filter-paper detection, the suppression ratio of varieties maintained ranged fiom 65.1％ to 92.0％; and bacteria-resistance region ranged fiom 2.0 to 11.0 mm. In addition, 8 anti-bacteria strains were obtained for biological control.%对从不同生态环境下采集的样品进行分离纯化,共得到菌株68株.经初筛,得到对番茄灰霉有颉颃作用的生防菌株16株,占分离菌株的23.5%.并对其中较强颉颃作用的9株菌株进行抑茵活性的测定.结果表明:滤纸片法得到的各菌株对番茄灰霉的抑制率在65.1%～92.0%之间,抑菌带在2.0～11.0mm之间,共获得颉颃菌株8株,占分离菌株的11.8%.
