Open Inoculation Technology of Edible Fungi

The key to adopting open vaccination should pay attention to the following points:

At present, the aerosol smoking method is widely used and effective is the KDA aerosol fumigation method produced in Fuzhou, Fujian Province. Generally, 3 to 4 grams of aerosol are used per m ~ 3 space. Closed fumigation for more than 0.5 hours, wait for the smoke to dissipate before entering the inoculation operation.

Second, the method of formaldehyde plus potassium permanganate disinfection produces formaldehyde steam to disinfect the inoculation room through the mixed reaction of formaldehyde and potassium permanganate, but some seed producers are not sure about this dosage, which is both wasteful and unsafe, and it can not be dispersed in time during vaccination. harmful to the health of vaccinators. The correct disinfection method should be disinfected for 30 minutes with a mixture of 40% formaldehyde 10~12ml and 5 grams of potassium permanganate per m3 space for 30 minutes. If there is a pungent smell of formaldehyde before inoculation, it can be eliminated by shaking the open bottle containing ammonia water a few times.

Third, if the continuous use of open vaccination production, the above two methods can be cross-applied at regular intervals to improve the disinfection purity of the inoculation room.
