Auricularia auricula planting: how to choose fungus strains?

How to choose fungus strain? What methods can be used to distinguish the quality of fungus? Please introduce the method of fungus strain selection method can refer to the following enumeration methods: first, pay attention to the appearance: see whether the bottle label is consistent with Auricularia auricula strain, in order to prevent wrong purchase. The culture time should be less than two months. from the day of inoculation, the bacteria age should be 30ml / 40d. At the same time, we should see whether the bottle wall is broken or the cotton plug falls off. Second, pay attention to the mycelium: the mycelium is pure and pure, and the thick, short and dense villi are high quality bacteria. If there are green, yellow, red, green, gray hyphae, it is the bacteria that have been infected with miscellaneous bacteria and need to be eliminated. Third, pay attention to the ear base: if there is no light black ear base between the bottle wall and the material, a small amount of ear base is normal, if there are too many, the passage times are too much, although the ear comes out early and more after inoculation, it does not grow big, and the yield is low. Pay attention to the sediment: if there is no or only light brown colloid on the bottle wall, it is a qualified strain; if there is a yellowish brown liquid, it belongs to an aging strain and cannot be purchased. Fifth, pay attention to the fungus: sawdust bacteria have mycelium on the surface, sawdust can no longer be seen, it is better to dig into blocks rather than loose. Not available if the clot has dried up and contracted. Sixth, pay attention to smell: remove the cotton plug, smell the bacteria fragrance, it is a qualified product; if the wine acid, mildew and other odors, it is a deteriorated bacteria, not available. Fungus strain precautions: 1. If the culture time is too short or the temperature is too low, the mycelium does not grow into the whole bottle or the mycelium does not grow into the sawdust, it should continue to be cultivated at the appropriate temperature, and then used for inoculation. 2. If the bacteria of the right age cannot be inoculated temporarily after being purchased, they should be stored in a clean, dry and dark room. 3. Before inoculation, it is strictly forbidden to pull out the cotton stopper, and the bacteria that have been opened and inoculated should not spend the night to prevent contamination by miscellaneous bacteria.
