【摘要】：【目的】制作巴尔喀什蘑菇培养料生产过程中,常发现一种腐生菌引起的病害,表现为棉籽壳发酵料发酵温度持续偏低,料面湿滑。研究该病害的病原和生物学特性,为该病害的有效控制提供依据。【方法】分离得到病原菌,观察形态特征和分析r DNA-ITS序列。【结果】该病原菌为粉红菌寄生菌(Hypomyces rosellus)的分生孢子阶段Cladobotryum noes菌寄生所致巴尔喀什蘑菇粉红菌病。该病原菌菌丝体最佳生长条件为20℃,属低温菌,pH 5.5偏酸性生长。葡萄糖为碳源,蛋白胨为氮源,光照对菌丝体生长有一定抑制作用。【结论】在食用菌生产过程中前期严格控制温度条件,做好二次发酵,加强通风和环境卫生管理有助于预防巴尔喀什蘑菇红菌病害发生。
[Abstract]:[objective] during the production of mushroom culture material from Barkash, a kind of disease caused by rot bacteria is often found, which shows that the fermentation temperature of cottonseed shell fermenting material is on the low side and the material surface is wet and slippery. The pathogen and biological characteristics of the disease were studied to provide the basis for the effective control of the disease. The morphological characteristics and the sequence of r DNA-ITS were observed. [results] the pathogen was caused by the parasitism of Cladobotryum noes in conidial stage of Hypomyces rosellus. The optimum growth condition of mycelium of this pathogen is 20 鈩，
