水稻细菌性基腐病,近几年在南方稻区陆续发生,浙江各地为害渐趋严重,已给水稻生产带来较为严重威胁。本文报导此病病原细菌的形态、染色反应、培养性状及生理生化反应等性状的观察及测定结果,初步确定引起此病的细菌是菊欧氏杆菌(Erwinia chrysanthemi Barkn.et al)。 In recent years, bacterial base rot disease of rice has occurred one after another in the southern rice area, and the damage has become more and more serious in various parts of Zhejiang Province, which has posed a serious threat to rice production. This article reports the pathogenic bacteria morphology, staining reaction, culture traits and physiological and biochemical reactions and other traits observed and measured results, initially identified the cause of the disease bacteria are Erwinia chrysanthemi Barkn.et al.
