10 Most Important Shiitake Mushroom Log Instructionsby Delun Kang Agriculture
There are a variety of mushrooms that are available but the one that is considered iconic is Shiitake. Although it requires specialized skills and techniques, it is the most widely cultivated mushrooms in the world. Apart from being tasty and nutritious, it has a longer shelf life and provides with bountiful yields when grown using the right tactics. Here are some instructions to get a better yield.
1. Choose the laying yard: You should plan beforehand where to keep Shiitake mushroom Log when they are inoculated with spawns. It should be kept under shade to prevent them from drying out. The ideal place would be beneath the canopy of a coniferous forest.
2. Tree species to be used: Oaktree is considered as the ideal Shiitake mushroom Log for growing mushrooms and there are companies which supply best quality logs. Other species that can be used are sugar maple, American beech, American hornbeam, and hophornbeam. However, evergreen trees like pine, spruce, hemlock, etc. are not recommended.
3. Tree to be cut down: Since it is essential to have fresh logs for inoculation, only living trees should be cut down. Fresh logs have high moisture content and little wild fungi which is important for producing mushrooms.
4. Size of logs: A log size of 4-6 inches in diameter is recommended because larger logs are more difficult to manage. A length of 3 to 4 foot is recommended as it can be managed easily for transporting and carrying.
5. When to inoculating logs: The logs should not be inoculated just after cutting. Wood from trees has a natural defense against a fungal invasion that includes phytoalexin compounds. It accumulates around the wound and increases in concentration in the following days. It is better to wait for 2 or 4 weeks so that the antifungal agents on the logs subside.
6. Type of log to be used: Both sawdust spawn and plug spawn can be used to inoculate the logs each having its own advantages and disadvantages. Plug spawn is simple to use requiring only a hammer but it is a bit expensive. Though plug spawn is slightly cheaper it requires a special tool.
7. Fruiting the mushrooms: The substrates are left to fruit naturally. Sometimes flushing with heavy rain or temperature changes may induce fruiting. However, in a forced production model, the fruiting is controlled by the growers according to a log rotation schedule that is preplanned.
8. When to shock: It is the process by which mycelium is forced into fruiting. This involves soaking the logs in coldest water for about 12 to 14 hours and then removed. After removing, the logs start fruiting within 3-5 days.
9. Shocking it again: The logs should be allowed to rest for 6-8 weeks after fruiting to be forced into shocking again.
10. When to harvest: Mushrooms should not be harvested depending on the size of the mushroom rather it should be determined according to its growth progress. It should be harvested when gills become visible and the outer edge gets curled under. Shiitakes generally get ready for harvesting 7-10 days after shocking. A knife should be used to ensure quick, clean and easy cutting of the stem without damaging the bark.
Fresh mushrooms should not be stored in a plastic bag. It should be stored inside paper bags and then refrigerated.
