Key Technical Points for Mycelium Running Management of Greenhouse Field-Grown Shiitake Mushrooms

After inoculation, stack the spawn bags in the incubation room for mycelium running. When the mycelium has grown to 6 cm wide, turn the stack; at 6-8 cm, turn the stack a second time. Arrange them in a triangular pattern to prevent overheating of the logs.

1. Piercing holes for aeration: If the mycelium around the edges is found to be shrinking, with the color changing from white to pale yellow and the mycelial coat thickening, this indicates that the mushroom logs are short of oxygen, and the first hole-piercing for aeration must be carried out. Make 3-4 holes around the inoculation point, 1.5-2.0 cm deep, to promote normal mycelial germination. After the mycelium has fully covered the entire bag, carry out a second hole-piercing for aeration, using a 1-cun iron nail to make holes on both sides of and behind the inoculation holes, 2-3 cm deep.

2. Mycelium running process: At 45-60 days of mycelium running, release air; release air once more at 70 days; move them to the field at 90 days. When more than half of each bag has turned from white to brown, open the bags to induce fruiting.
