草菇生产中常见的杂菌有鬼伞属的一些种,如绒鬼伞,长把鬼伞等。鬼伞一般在草菇出菇前期或后期出现。绒鬼伞是最常见的一种,这种鬼伞幼时呈白色锥形子实体,菌柄较粗,菌伞表面覆盖一层绒毛状鳞片。菌伞很快开裂,一夜之间就自溶放出墨汁粘液,严重发生会大量消耗培养料中的营养,影响草菇菌丝正常生长发育,造成草菇减产。其防治要点如下: Mushrooms common in the production of some species of Coprinus, such as velvet umbrella, a long umbrella and so on. Coprinus generally fruiting mushroom fruiting early or late appear. Velvet umbrella is the most common kind, this kind of Coprinus was a white conical fruiting body, thicker stems, mushroom umbrella surface covered with a layer of hairy scales. Umbrella quickly cracked, overnight release of ink mucus from autolysis, a serious occurrence will consume a large number of nutrients in culture materials, affecting the normal growth and development of mushroom mushroom mycelium, resulting in straw mushroom production. The prevention and cure points are as follows:
