- 摘要:
- 对从水稻纹枯病稻田土壤中分离筛选的176株细菌进行抑菌率比较,并对其进行鉴定,以期为水稻纹枯病的生物防治提供理论依据。结果表明:SR32菌株抑菌带为16.4 mm,抑菌率为73.6%,根据形态学和生理生化特征初步鉴定为枯草芽孢杆菌(Bacillus subtilis)。
- Abstract:
- In order to supply theory evidence for biological control of rice sheath blight identification was carried out.The restraining ratio among total 176 bacterial strains from rice field soil with rice sheath blight were compared and the identification was carried out. The results indicated that strain SR32 was preliminary identified as Bacillus subtilis based on morphological, physiological and biochemical characteristics with its restraining band 16.4 mm and restraining ratio 73.6%.
