沙姜软腐病是一种具有毁灭性的细菌性病害,发病率10—80%不等,严重阻碍沙姜生产的发展。根据广西各地采样分离得的菌株,在形态,染色反应,培养性状,生理生化反应等方面与番茄青枯病菌相似。初步证明,沙姜细菌性软腐病菌是属青枯病假单胞杆菌[Pseudomonas solanacearum(Smith)Smith]。 Shajiang soft rot is a devastating bacterial disease, the incidence of 10-80% range, a serious impediment to the development of sand ginger production. Based on the isolates collected from different parts of Guangxi, the isolates were similar to that of R. solanacearum in morphology, staining reaction, culture traits, physiological and biochemical reactions. Preliminary evidence shows that the bacterial strain of ginger is a bacterial strain of Bacillus licheniformis [Pseudomonas solanacearum (Smith) Smith].
