1. Pleurotus eryngii is industrially produced. After the primordium is differentiated, many small mushroom buds grow. Due to the limitation of nutrition and space, most of these mushroom buds can't grow into commercial mushrooms if they are not thinned, so they must be thinned in time. The specific methods are as follows: after catching the bacteria, enter the mushroom house, and the bottle mouth is turned down into an empty basket, which is beneficial to restore the growth of mycelium. The air humidity is 90% ~ 95%, the temperature is 12 ~ 15℃, and the ventilation is moderate.

2. After the mycelium resumed growth, the humidity dropped to 80% ~ 85%, resulting in humidity difference; The light intensity is 500 ~ 800 LX, the CO2 concentration is below 0. 1%, and mushroom buds are formed in 7 ~ 10d. If the concentration of CO2 exceeds 0. 1%, the mushroom is deformed. After the mushroom buds are formed, the basket is turned over so that the bottle mouth faces upwards, and mushroom cultivation is carried out. Temperature 15 ~ 17℃, humidity 90% ~ 95%. Use a sprayer to adjust the humidity. Don't spray water directly on mushrooms. When the mushroom buds grow to the size of peanuts, use a knife to remove deformities and some over-dense mushroom buds. Leave 3 ~ 4 mushroom buds in each bottle.
