上海郊区于1965年前后在个别菇房发现蘑菇“死菌丝”现象,罹病菇房若不及时防治,往往会连年发生,且发病面积也会逐年扩大。据观察,在出菇后,有的菇房床面上往往出现一块块不出菇的病区。剥开病区细土仔细检查,则会发现粗土上的线状菌丝萎缩,似烤黄,所以也称“黄菌丝”。以后萎缩变黄的菌丝体,慢慢的死亡溶解。奇怪的是病区培养料内的菌丝体,不仅看不出病症,反而显得更加浓密旺盛,但培养料中的菌丝一旦长上粗土,便一再重复变黄而萎缩死亡,因此,我认为将这种现象称为“死菌丝”更为确切。本文就蘑菇“死菌丝”的发生发展和防治措施,作一简略的介绍,以供栽培单位参考。
Shanghai suburbs in 1965 before and after the mushrooms found in individual mushrooms “dead mycelium” phenomenon, if not timely prevention and treatment of mushroom house, often occur year after year, and the incidence of the area will also be expanded year by year. It is observed that, after fruiting, some mushroom bed surface often appear a piece of non-fruiting ward. Peel the ward careful examination of fine soil, you will find the linear mycelium atrophy on coarse soil, like roasted yellow, it is also called “yellow mycelium.” After shrinking yellow mycelium, slowly dissolve the death. Curiously, the mycelia in the ward are not only incurable but they are even more thickened. However, once the mycelium in the culture material grows in coarse soil, it repeats yellowing and shrinks and dies. Therefore, I Think of this phenomenon as “dead mycelium” more precisely. This article on the mushroom “dead mycelium” occurrence and development and prevention measures for a brief introduction for the cultivation unit for reference.
