杨梅杆菌是银耳制种中的顽敌,也是栽培者“望而生畏”不可救药的菌害。一旦菌种被侵染,接种到栽培袋上就会造成只长菌丝不出耳,成批菌袋以失败告终。杨梅杆菌在菌种生产初期不易发现。肉眼也难以辨认。一直发展到严重时才能看得出来。杨梅杆菌的菌丝在菌种料面上,呈微小粒状,灰白色结硝,用显微镜观察可看出明显的萎缩。而银耳菌丝中是由耳友菌俗称香灰菌丝和银耳菌丝两种混合而成。而银耳菌丝 Mycelia is a stubborn enemy in the production of Tremella, and is also a “daunting” grower of cultivars. Once the strain is infected, inoculation into the cultivation bag will result in only long mycelium not out of ears, the bulk of bacteria bags ended in failure. Mycobacterium is not easy to find in the early stage of strain production. Naked eye is also difficult to identify. Can only be seen when it has developed to seriousness. Mycelia of Mycobacterium on the surface of bacteria species, was small granular, gray-knot nitrate, observed with a microscope can be seen obvious atrophy. The white fungus mycelium is commonly known as auricular mycelium and white fungus mycelium mixed two. And white fungus mycelium
