蘑菇的小菌核病是由一种伏革菌的分生孢子阶段的病原菌引起的。这种病主要发生在培养料中,被浸染的培养料中有许多黄色的小颗粒,外形似鱼籽,故有人称其为鱼籽菌,常在播种后就在培养料中发生。生有小核菌的培养料,蘑菇菌丝通常长不好,严重时很难蔓延,培养料中只有几条稀疏的线状菌索,严重影响蘑菇产量,有时甚至颗粒无收,必须引起高度重视,做好预防工作。一、形态特征小核菌属半知菌纲、无孢霉群、小核菌属。菌
Small sclerotinia of a mushroom is caused by a pathogen of the conidiospore stage of a genus Fulvia. This disease occurs mainly in the culture material, the disseminated culture material has many small yellow particles, the appearance of fish seeds, it is called a fish-based bacteria, often sown in the culture material after sowing. Stems of students with the culture of mushroom, mushroom mycelium is usually not grow well, it is difficult to spread in severe cases, the culture material is only a few sparse linear fungus, seriously affect the yield of mushrooms, and sometimes even crop failure, must be caused by height Pay attention to preventative work. First, the morphological characteristics of Pichia non-known Mycobacterium gang, non-spore mold group, the genus Sclerotinia. bacteria
