Management of mushroom production in large-scale production of Oyster Mushroom

1. Three-dimensional placement

After the mycelium is full, it is moved into the mushroom shed in time for mushroom management. At present, three-dimensional placement in the shed is mostly adopted. The site can be properly ridged according to the row spacing, and plastic film, woven bags or red bricks can be laid to physically isolate the mushroom bags and soil to cut off the transmission path of soil-borne diseases. Stack the mushroom bags on it. The mushroom bags are placed layer by layer, 4 to 8 layers high, and the length depends on the specific situation of the mushroom production site. The broken rows need to be left about 60 cm for operation, and the rows are left with a mushroom picking and management walkway of 80 to 120 cm.

2. Bud promotion

After the mushroom bags are stacked, it is best to take bud promotion measures to facilitate neat mushroom production and facilitate later management. If there is a thick mushroom skin at the bag mouth, you can use a small iron rake or tweezers to remove the old mushroom skin to expose the mycelium. When budding, open doors and windows at night to lower the ambient temperature, increase light during the day to raise the temperature of the mushroom shed, create a day and night temperature difference of 8~12℃, keep the ground and walls moist, increase the relative humidity of the air to about 90%, and increase the humidity by increasing the ground humidity and spraying fine mist in the air. Avoid direct watering, and avoid water accumulation on the surface of the mushroom buds to avoid dead buds and outbreaks of bacterial yellow spot. Increase ventilation and provide scattered light to promote the differentiation of mushroom buds.

Primordial differentiation and fruiting body growth have different requirements for oxygen. Under semi-closed conditions, maintaining an appropriate carbon dioxide concentration can promote the occurrence of primordia. Carbon dioxide concentration also affects the density of primordial occurrence. Primordia have poor adaptability to the environment and weak resistance to stress. Ventilation should be carried out slowly, the ventilation volume should not be too large, the ventilation time should not be too long, and the primordia or mushroom buds should not be blown directly. If the wind is strong and the airflow is too fast, the fungus bag will lose water and the primordium will dry up. Scattered light stimulation is conducive to the formation of primordium, differentiation of fruiting bodies and growth and development of Pleurotus ostreatus
