Matters needing attention in the selection and purchase of the latest Auricularia auricula strains
The cultivation of Auricularia auricula has a long history, and it is the first cultivated edible fungus variety in the world. It has a history of more than 1400 years. If you want to cultivate Auricularia auricula, the strain is the key point, so what medicine should you pay attention to when choosing the strain? Let's get to know it.
1. Pay attention to the appearance
At the time of purchase, we should see whether the label of the bottle is consistent with the strain of Auricularia auricula, in order to avoid purchase errors, the culture time should be less than two months, calculated from the day of inoculation. The bacterial age should be 30-40 days. At the same time, it depends on whether the bottle wall is broken or the cotton plug falls off. If so, do not choose.
2. Pay attention to the hyphae
If there are green, yellow, red, cyan, gray and other color hyphae in the hyphae, it means that the hyphae are not infected by other miscellaneous bacteria, and should not be purchased.
3. Pay attention to the ear base
Between the bottle wall and the material, if my light black ear base is a high-quality strain, if a small amount of ear base is normal, if the number is too much, then it means too many passages, although the ear comes out early and more after inoculation, but it does not grow big and the yield is low, so it is not recommended to buy it. In addition, there is no or only light brown gel on the bottle wall, so it is a qualified strain. If there is a yellowish brown liquid, it belongs to an aging strain and cannot be purchased.
4. Pay attention to the bacteria clot
Sawdust bacteria have hyphae on the surface, and sawdust can no longer be seen. It is better to dig into lumps rather than loose. If the fungus has dried up and shrank, it is not recommended to buy it.
5. 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.
The above is the introduction of the matters needing attention in the selection and purchase of Auricularia auricula strains. I hope it can help you. If you want to know more about it, please follow us.
