Fungus strain preservation method

The invention provides a fungus strain preservation method. Dry heat sterilized allochroic silicagel particles and dry small filter paper covered with fungus hyphae and/or fungus spores are put into a transparent or semitransparent sterile microcentrifuge tube or a sterile finger-shaped tube, the microcentrifuge tube or the finger-shaped tube is sealed with a sealing film, the sealed microcentrifuge tube or finger-shaped tube is stored in a transparent or semitransparent microcentrifuge tube freezing box, and the transparent or semitransparent microcentrifuge tube freezing box is put in a -20 DEG C refrigerator for preservation. When the method is used for fungus strain preservation, the survival rate of strains is high, the preservation time is long, and the dry state of the strains is easy to observe. In addition, under a stable low-temperature dry condition, the strains are in a dormant state, and the biological characteristics of the strains are not prone to degrade, so that the inherent characters of the
