Shiitake Mushroom Stick Hole Piercing
2026-05-15
1. Purpose of Hole Piercing
When mycelium grows far away from inoculation holes, air circulation becomes poor. Metabolic waste accumulates easily, leading to mycelium aging and oxygen deficiency inside mushroom sticks.
Hole piercing can activate mycelium growth, boost metabolism, and provide suitable conditions for summer conservation and mycelium color transformation.
2. Piercing Methods
Mushroom sticks need 2 to 3 times of hole piercing in cultivation. Follow the rules: from few to many, shallow to deep, thin to thick holes; operate in low temperature in batches.
First Piercing
Carry out when mycelium circle reaches 6-8 cm for film-sealed sticks, or 10 cm for bag-covered sticks.
Drill 4-6 holes beside each inoculation hole, hole depth 1 cm, total 16-24 holes per stick.

Second Piercing (Minor Aeration)
Operate when mycelium connects on the back of mushroom sticks.
Drill 8 holes around each inoculation position, hole depth 1-1.5 cm, total about 30 holes per stick.
Do not make holes too large, too deep or too many, to prevent excessive water loss.

Third Piercing (Major Aeration)
Pierce 7-10 days before bag removal, when one third of stick surface forms tumor-like protrusions.
Hole depth 4-5 cm, total 60 holes per stick.
It accelerates mycelium maturation, discharges waste gas, stimulates mushroom budding and reduces deformed mushrooms.

Simple Piercing Tool
Make a nail wooden board, which can punch 20 holes at one time to improve working efficiency.
3. Key Notes
- Forbidden piercing areas: substrate separation positions and contaminated parts. Stop piercing above 28℃, strictly prohibit operation over 30℃ to avoid mycelium burning and rotten sticks.
- Pierce at 45° oblique angle to fit mycelium growth shape, lower sundry fungus infection rate.
- Adjust hole quantity and depth freely: use deeper and more holes for compact or high-water-content substrate; use shallower and fewer holes in dry and ventilated environment.
- The internal temperature of mushroom sticks will rise after aeration. Keep core temperature between 18℃-25℃ by proper ventilation to ensure normal mycelium growth.
