How to choose the strain of Auricularia auricula?

How to choose the strain of Auricularia auricula? Do you have any skills? Also ask experienced netizens to help introduce that the quality of Auricularia auricula strains determines the yield of Auricularia auricula. The farming network has sorted out the selection methods of Auricularia auricula strains, which are listed below for netizens' reference. Method 1. The excellent mycelium of Auricularia auricula is white, like fine wool, short and neat, dense, sturdy and powerful, extending side by side to the bottom of the bottle, growing evenly, consistent up and down, dug out into blocks, not loose. Method 2. Good Auricularia auricula will generally secrete brown water droplets on the surface of the bacteria after the mycelium is full. After that, light yellow transparent gelatinous ear buds appeared around the bottle wall and on the surface. Method 3. The excellent strain column of Auricularia auricula is close to the bottle wall, and the bottle with a small amount of white water droplets on the inner wall is the fresh strain. If there is light yellow stagnant water at the bottom of the bottle, the bacteria column shrinks away from the wall, which is an aging strain and can not be used. Method 4. Normal bacteria have the unique aromatic smell of Auricularia auricula. If there is a smelly and moldy smell, or the phenomenon of patchy and spherical non-bacteria, it is bacterial contamination, and if there are other colors such as red, green, yellow, black, etc., it means that it has been contaminated by miscellaneous bacteria and can not be used. Method 5. If a light black glue (ear base) appears between the quality of Auricularia auricula culture medium and the bottle wall, it shows that it is precocious or has too many times of expansion, and the ear slices are small, large in quantity, not easy to grow, poor quality and low yield after cultivation. Should be eliminated. Method 6. If wood particles can be seen in the bottle and there are few hyphae, it means that the culture time of Auricularia auricula strain is too short and should continue to be cultured. If there is no significant change after a period of time, the medium is not nutritious enough and should be supplemented. Method 7. If the fungus strain grows to about half or a corner does not continue to grow, it may be too dry or too wet. If the mycelium grows neatly, dense, suddenly sparse, and has a clear boundary, it means that the upper material is moderate and the lower part is too dense.
