(1) Management of the spawning period: The management of the mycelium growth and development stage is mainly to regulate temperature, keep moisture and prevent contamination by miscellaneous bacteria. In order to prevent contamination by miscellaneous bacteria, the room temperature should be controlled below 15℃ within 10 days after sowing. Two days after sowing, the strain began to germinate and gradually grow around. At this time, the temperature change in the culture material should be checked several times every day, and the temperature of the material should be controlled below 30℃. If the material temperature is too high, the film should be uncovered, ventilated and cooled, and then the film should be covered after the temperature drops. After the material temperature is stabilized, it is not necessary to tilt the film. After 10 days, the hyphae grow all over the material surface and into the material layer. At this time, the room temperature can be raised to 20-25℃. If contamination of miscellaneous bacteria is found, lime powder can be sprinkled on the growth place of miscellaneous bacteria or wiped with 0.3% carbendazim. During this period, the relative humidity of the air will be kept at about 65%. Under normal circumstances, after sowing, the mycelium will grow full of the whole culture material in 20-30 days.

(2) Management of fruiting period: After hyphae are full of culture materials, open the doors and windows of the mushroom house and plastic film 1 hour at the lowest temperature every day, and then cover them, so as to increase the temperature difference between the material surfaces and promote the formation of fruiting bodies. It is also necessary to spray water according to humidity to adjust the relative humidity of indoor air to above 80%. When the mycelium reaches physiological maturity and meets suitable temperature, humidity, air and light, it will twist into a lot of gray-white millet-like bacterial buds. At this time, it can be sprayed into the space to keep the relative humidity of indoor air at about 85%. Do not spray water on the material surface, so as not to affect the development of mushroom buds and cause the death of young mushrooms. At the same time, the plastic film should be erected, so that it is ventilated and moist, and the indoor temperature can be kept at15-18℃. After the bud pile is formed, it grows rapidly. After 2-3 days, when the stalk is extended and the original cap with gray-black or brown oblate shape is formed at the top, the covered film can be lifted off, and a small amount of water can be sprayed on the material surface to keep the relative humidity of indoor air at about 90%. Spray it 2-3 times a day, and keep the temperature around 15℃.
