通过对香菇菌棒生产的几个关键环节(木屑堆积时间、装填料方式、灭菌和冷却方式、接种培养等)进行试验观察,探究出降低菌棒生产污染率的关键步骤:木屑经过3个月以上预堆积,可以有效减少因木屑对袋子的机械损伤而造成的菌棒污染;双层袋和卧式装袋机可以降低污染率;高压灭菌过程中采用阶段性操作方式和常压灭菌过程中延长灭菌时间均能起到降低污染的效果;在配有过滤装置的冷却室,灭菌培养基快速冷却到15℃左右有利于降低污染率;双人接种箱式和相对恒温的培养环境也是降低污染率必不可少的重要环节。
The key steps of mushroom stick production (sawdust accumulation time, packing material, sterilization and cooling methods, inoculation and so on) were observed and observed to explore the key steps to reduce the pollution of mushroom stick production: sawdust after 3 Month or more pre-piled, can effectively reduce due to the mechanical damage caused by sawdust bags caused by bacteria stick pollution; double-bag and horizontal bagging machine can reduce the pollution rate; autoclave process using phased operation and atmospheric pressure off Bacteria lengthening the sterilization time can play a role in reducing pollution; in the cooling chamber equipped with a filter device, the sterilization medium is quickly cooled to about 15 ℃ conducive to reduce the pollution rate; double inoculation box and the relative constant temperature culture Environment is also an essential part of reducing pollution.
