Edible fungus open inoculation technology

In recent years, with the shift from the single pattern of mushrooms, straw mushrooms, and oyster mushrooms in the Shanghai area to the conventional and rare varieties, the production of containers for some strains has also evolved from 750 ml glass bottles. Various types of plastic bags, the traditional way of inoculation can no longer adapt to large-scale plastic bag seed production, so take a simple and rapid open inoculation came into being. However, in the practice of production, some seed producers did not operate properly due to the sterilization method, resulting in a reduction or even failure of the seed production rate. Take the key to open vaccination should pay attention to the following points: First, the aerosol smoking method At present, the more widely used and effective is the kda (Keda brand) aerosol smoking method (agent) produced in Fuzhou, Fujian Province. Typically 3 to 4 grams of aerosol is used per m3 of space. Closed smoke for more than 0.5 hours, until the smoke is exhausted (usually 3 to 4 hours) before entering the inoculation operation. Second, formaldehyde and potassium permanganate disinfection method through the formaldehyde and potassium permanganate mixed reaction, generate formaldehyde vapor to sterilize the inoculation room, but some producers do not grasp this amount, both wasteful and unsafe, and can not be inoculated Dispersed in time, harmful to the inoculation personnel. The correct disinfection method should be 40% formaldehyde 10~12ml plus 5~7g potassium permanganate per m3 space mixed reaction disinfection 30 to 50 minutes, if there is a pungent formaldehyde odor before inoculation can be filled with ammonia bottle open A few shakes can be eliminated (if ammonia is not available, carbon ammonia can also be used). Third, if continuous use of open inoculation production, the above two methods can be applied at intervals to improve the purity of the inoculation room.
