The preservation method of the edible mushroom mother-family is usually sealed with refrigerators, paraffin wax, sand burying, physiological saline, etc. However, for rural growers, the cost of buying a refrigerator is too high; paraffin wax sealing is a long time, and there is no germination phenomenon; Buried is very easy to pollute; physiological saline, such as the concentration is not suitable, it is difficult to survive. The author used salt water with a concentration of 1% to 1.5%, added to the medium for salification, autoclave for 45 minutes, sterile inoculation, tampon sealing, after the bacteria grew well, put in the bag, Sealed, preserved at room temperature for 9 months, after the transfer of new media, easy to restore, the survival rate of more than 95%.
