香菇栽培过程中,往往在子实体分化、大小菇蕾出现时,常发生烂菇现象。其原因:多是长菇期间连续降雨,特别是春季温暖潮湿的情况下,如菇床湿度过大,易使杂菌侵入为害,造成烂菇;也有的属于病毒性病害,使菌丝退化,导致子实体腐烂,有的属于管理不善,冬季喷水过湿,使相对湿度高达95％以上,加上菇筒通风不好,菇床内二氧化碳积蓄过多,致使菇蕾无法正常发育而霉烂。防止烂菇的主要措 Mushroom cultivation process, often in the fruiting body differentiation, the size of mushrooms appear, mushroom phenomenon often occurs. The reasons are: continuous mushrooms during the continuous rainfall, especially in the spring warm and humid conditions, such as mushroom bed humidity is too large, easy to make bacteria invasion, causing rotten mushrooms; some are viral diseases, the mycelium degradation, Resulting in fruiting bodies decay, and some are poorly managed. In winter, the water is too wet and the relative humidity is as high as over 95%. In addition, the mushrooms have poor ventilation and excessive accumulation of carbon dioxide in the mushroom bed, causing the mushroom buds to fail to develop normally and become rotten. The main measures to prevent rotten mushrooms
