【摘要】 从茶园土壤分离到62株放线菌株,采用平板对峙培养法对茶白星病(Phyllosticta theafolia Hara)进行拮抗放线菌的筛选。结果表明,共获得拮抗放线菌菌株9株,编号分别为:F1、F2、F3、F5、F8、F11、F15、F57、F59,其中菌株F1、F2、F3、F5、F8抑菌活性强且抑菌谱广,对辣椒炭疽病菌(Colletotrichum capsici)、烟草黑胫病菌(Phytophthora var.nicotianae)、水稻纹枯病菌(Rhizoctonia solani)、黄瓜腐霉病菌(Pythium aphanidermatum)亦有较好的拮抗作用。更多还原

【Abstract】 62 actinomyces strains were isolated from tea garden soil, 9 antagonistic actinomyces were screened out from them by plate confrontation method, which have effective inhibition on Phyllosticta theafolia Hara and were named as F1, F2, F3, F5, F8, F11, F15, F57, F59. Strains F1, F2, F3, F5, F8 had a broad-spectrum antimicrobial activity and also showed better inhibiting effect on Colletotrichum capsici, Phytophthora var. nicotianae, Rhizoctonia solani, Pythium aphanidermatum.更多还原
