| 摘 要： | 从全国6省12个地区的26种植物根围采集到土壤样本50份。经室内分离、纯化后得到以芽孢杆菌为主的细菌菌株226个。以水稻、小麦和棉花等6种农作物上主要病原菌(8种真菌,4种细菌)为指示菌对这226个菌株进行平板双培养法抑菌测定,分别筛选到至少对1种病原真菌或细菌有颉颃活性的菌株95个和78个。对进一步研制防治不同作物病害的生物制剂建立了一个颉颃菌资源库。

| Abstract: | Fifty soil samples were collected from rhizosphere of 26 plant species in 12 locations of 6 provinces. As a result of isolation and purification, 226 strains (mainly Bacillus spp.) were obtained. Their antagonistic activity was tested against several important pathogens, 8 species of fungi and 4 species of bacteria, in rice, wheat, cotton, tomato, Chinese cabbage and faba bean. Of the 226 strains, 95 were found to be antagonistic to one or more pathogenic fungi and 78 to bacteria. |
