近年来,一些蘑菇产区农民对蘑菇培养料的堆制越来越粗放,二次发酵也不规范,使蘑菇白粒霉病在部分菇区成为主要病害之一。菇床一旦发生白粒霉菌,其产量和质量将在不同程度上受到影响,轻者减产10～20%,重者减产40～50%,甚至更高,成为蘑菇栽培提高效益的一大障碍。为此根据该病在菇床上发生的特点及其防治作以下概述,以供栽培者参考。一、症状特点:该菌发生在菇床培养料内。被侵染的菇床,通常是在播种10多天后,菇房培养料中散发出浓厚的霉味。表面看不到白粒霉菌,而料中却混生有形如鱼卵或蚕卵大小的小颗粒,肉眼看去呈
In recent years, some farmers in mushroom producing areas have become more and more extensive in the compost of mushroom cultivation materials, and the secondary fermentation is not standardized, making mushroom mildew one of the major diseases in some mushroom areas. Mushroom bed in the event of white mold fungus, its yield and quality will be affected in varying degrees, the light yield reduction of 10 to 20%, weight reduction of 40 to 50%, or even higher, become a major obstacle to mushroom cultivation to improve efficiency. To this end, according to the characteristics of the disease occurred in the mushroom bed and its prevention and control for the following overview, for the grower’s reference. First, the symptoms and signs: The bacteria occurred in mushroom bed culture material. Infected mushroom bed, usually more than 10 days after sowing, mushroom house culture material exudes a strong musty. The surface can not see the white mold fungi, but the material is mixed with tangible things such as egg or silkworm egg size small particles,
