Summer oyster mushroom cultivation is not difficult; punching holes for ventilation and oxygen supply is the key

Summer temperatures are relatively high, and three-dimensional cultivation of oyster mushrooms in plastic bags often leads to severe contamination, and can even cause cultivation failure. Whether the spawn-running stage can be successfully passed is the key to summer oyster mushroom cultivation, and it is also the issue mushroom growers worry about most.

Summer temperatures are relatively high, and three-dimensional cultivation of oyster mushrooms in plastic bags often leads to severe contamination, and can even cause cultivation failure. Whether the spawn-running stage can be successfully passed is the key to summer oyster mushroom cultivation, and it is also the issue mushroom growers worry about most. Practice has proven that punching holes for ventilation and oxygen supply is an effective method for solving the problems of summer oyster mushroom cultivation.

1. Timing of hole punching

Generally done 3-5 days after spawning, when the mycelium turns white, germinates, and begins to extend into the substrate. If holes are punched too early, the mycelium has not yet started to grow and contamination by foreign microorganisms is likely; if holes are punched too late, the mycelium lacks oxygen during its development period, which affects the growth and development of the mycelium.

2. Location of hole punching

The location of hole punching should be strictly controlled on the spawn layer or where the mycelium is extending. Especially when the amount of spawn used is small and the mycelium extends slowly, holes must not be punched randomly all over the bag, so as to avoid contamination by foreign microorganisms and pest damage.

3. Size and number of holes

For punching holes, a pin is sufficient (bind 3-4 pins to a chopstick). The number of holes is 10-12 per bag around the spawn-running layer each time; afterward, as the mycelium develops and extends, punch holes once every 5-7 days, and 3 rounds of hole punching are sufficient for the entire spawn-running period.

4. Advantages of the hole-punching ventilation and oxygen-supply method

1. It promotes fast spawn running and mushroom emergence and shortens the cultivation cycle. 2. It prevents contamination by foreign microorganisms, increases the success rate of summer oyster mushroom cultivation, and greatly reduces investment risk. 3. It enables year-round oyster mushroom production, makes up for the shortage of fresh oyster mushrooms in summer, and thereby greatly increases the economic benefits for mushroom growers.
