根据本人多年来栽培实践,就袋栽香菇杂菌污染的主要原因作一浅析。一、竞争性杂菌污染主要为害香菇菌丝体。常见的有木霉、青霉、链孢霉、曲霉、根霉、毛霉。一旦污染在基质内大量繁殖,与香菇菌丝争夺养份、水份。直接或间接地杀死香菇菌丝,占领生长场所。当用玻璃瓶制作菌种时,填完料后,如果瓶口没有清洗干净,就为杂菌提供了滋生场所。或棉塞受潮,霉菌便会在棉塞 According to my cultivation practice over the years, the main reason for bagging mushroom contamination. First, competitive bacterial contamination of the main damage mycelium. Common Trichoderma, Penicillium, Neurospora, Aspergillus, Rhizopus, Mucor. Once contaminated mass propagation in the matrix, fight with mushrooms mycelium nutrients, moisture. Kill mycelium directly or indirectly, occupy the growing place. When using glass bottles to produce bacteria, fill the material, if the bottle is not cleaned, it provides breeding grounds for bacteria. Or tampons damp, mold will be in the tampon
