What should we pay attention to when selecting Auricularia auricula? Please guide the selection of Auricularia auricula to pay attention to the following points: pay attention to the appearance. See if the label of the bottle is consistent with the strain of Auricularia auricula, in case of wrong purchase. The culture time should be less than two months. From the day of inoculation, the bacteria age should be 30-40 days. At the same time, the bottle wall should be broken or the cotton stopper will fall off. Pay attention to the mycelium. The hyphae with high purity, stout villi and short dense hairs 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. Pay attention to the ear base. If there is no light black ear base between the bottle wall and the material, it is an excellent strain, and 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. Pay attention to the clot. There are hyphae on the surface of sawdust bacteria, and sawdust can no longer be seen, so it is better to dig into blocks rather than loose. Not available if the clot has dried up and contracted. Pay attention to the smell. If you remove the cotton plug and smell the fragrance of the strain, it is a qualified product; if you send out a peculiar smell such as alcohol acid, mildew and so on, it is a deteriorating strain and is not available. Be careful to use it skillfully. If the culture time of the strain is too short or the temperature is too low, the hyphae do not grow into the whole bottle or the hyphae do not grow into the sawdust, they should continue to be cultivated at the appropriate temperature before being used for inoculation. 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. Before vaccination, it is strictly forbidden to pull out the cotton stopper, and the bacteria that have been opened for inoculation should not be inoculated overnight to prevent contamination by miscellaneous bacteria.
