为了提高食用菌制种成品率,减少操作过程中酒精灯产生的废气对人体的危害,我们于1986年开始用压缩无菌空气代替酒精灯进行试验。1987年2～3月采用该工艺接种了8000余袋黑木耳(每批500多袋),接种口污染率0～1%;7～9月接种了18000余袋木耳及香菇(每批500多袋),接种口染污率为0～2%,其中接种后不再搬动的成品率达100%。实践证明,该工艺是可行的,具体方法如下:(一)设备;天津产WM—4型无油空气压缩机一台,与之配套用油水分离器及过滤器各一个。(二)方法:用橡胶管连接上述设备,从过滤器
In order to improve the yield of edible fungi and reduce the harm to the human body caused by the exhaust gas generated by the alcohol lamp during the operation, we started to test it with compressed sterile air instead of alcohol lamp in 1986. From February to March, 1987, more than 8,000 bags of black fungus (more than 500 bags per batch) were inoculated by the process from February to March. The contamination rate of inoculation mouth was 0 to 1%. From July to September, more than 18,000 bags of fungus and shiitake mushrooms were inoculated Bag), the inoculation mouth staining rate of 0 to 2%, of which no longer move after inoculation of the finished product rate of 100%. Practice has proved that the process is feasible, the specific methods are as follows: (a) equipment; Tianjin produced WM-4 oil-free air compressors, with a supporting oil-water separator and a filter. (B) Method: Connect the above equipment with rubber hose from the filter
