蘑菇“棉絮状”杂菌是蘑菇大床栽培危害严重的真菌性病害。经复旦大学生物系张继忠老师初步鉴定,属半知菌纲、丝孢目,丛梗孢科,粉孢属。(一)病源:土壤是该病菌主要来源,不理想培养料的粪块亦是该病菌的寄生地方。(二)生活习性:经实验证明,该病菌生长温度范围10℃至25℃,最适宜温度为20℃。酸碱度(pH 值)为5.5至8.5,最适宜的是7。培养料含水量在60%以上时,随着湿度的增加,其生长速度相应加快。它比其
Mushroom “cotton-like” bacteria is a fungal disease of serious fungal diseases. The Department of Biology, Fudan University, Zhang Jizhong preliminary identification of the teacher, is a semi-known Myceliophilia, Silicocephalidae, Plexiform Branch, powder spores. (A) pathogen: the soil is the main source of the bacteria, the fecal material is not ideal culture material is also the parasitic places of the bacteria. (B) habits: The experiment proved that the bacteria growth temperature range 10 ℃ to 25 ℃, the most suitable temperature is 20 ℃. The pH (alkalinity) is 5.5 to 8.5, most preferably 7. When the water content of the culture material is above 60%, the growth rate of the culture material increases correspondingly with the increase of humidity. It is better than it
