菌种培育过程中应注意哪些问题
①培养室应清扫干净并严格消毒。
②菌种瓶应先竖放，当菌丝萌发定植后，改为横卧叠放。横放的菌种瓶可经常转动，使瓶内水分分布均匀。
③适时检查：有杂菌要及时清理；菌种未萌发，应补接菌种。当菌丝长满料面并深入料内1～2cm后，可改为5～7天检查一次。
④注意保持和调整培养室的温度：起初应保持菌丝生长的适宜温度，使菌丝能尽快生长、吃料，当菌丝快长满瓶时，要降低培养温度2～3℃，使菌丝健壮、增强生活力。
⑤注意调节空气、光照和湿度：要保持室内空气新鲜（经常通风换气），避免强光照射（应遮光），避免空气湿度过大（可减少污染）。
⑥做好防虫、防鼠、防杂菌工作。
⑦菌种长满后7～10天应及时转接。
