After the mushroom sheds are sterilized, they are transported to the mushroom sheds to receive the strains. The stacking level is determined by the temperature level. When the temperature is high in the summer and autumn, 2-4 layers are stacked. The material bags are piled into a “#†shape, cross-discharged to facilitate heat dissipation and leave the access road; when the temperature is low in the spring and winter, the bacteria bed A layer of rice straw or wheat straw should be laid on top of 10-12 layers and covered with plastic film or straw curtains to increase the temperature of the pile and promote the growth of mycelium.
The main points of germination management are:
The first is to maintain the temperature, insert thermometers between the bags regularly, pay attention to changes in stack temperature. The germination temperature is preferably 25°C to 30°C. When the temperature is higher than 30°C, the heap should be scattered in a timely manner to increase the ventilation volume to prevent the high temperature from burning out the hyphae. When the temperature is lower than 20°C, try to increase the temperature and keep warm.
The second is ventilation: The mushroom shed is ventilated 2-3 times a day for 30 minutes each time. When the temperature is high, it is ventilated sooner or later. When the temperature is low, it is ventilated at noon.
The third is to keep it dry. The relative humidity in the mushroom shed is 60%-70%.
Fourth, the light should be dark and weak light is conducive to mycelial growth.
The fifth is turning. After the stacking, it is turned every 5-7 days, and the lower material bag is smashed upwards. The upper layer is smashed downwards, and the inside and the outside are squatting so that the temperature is consistent and the bacteria are neat.
Sixth, ventilation supplements oxygen. The use of closed-end spurs with two ends, in the early stage of germination, the oxygen content in the bag can meet the needs of mycelial growth. With the increase of mycelial growth, the oxygen content in the bag is insufficient, which will affect the normal growth of mycelium. .
When 10-15 days after inoculation, when the two mycelia of the bag are each 2-3 cm long, they can be punctured 8-10 at the same distance by 1-2 cm at the back of the mycelial growth line. , Or use sharpened bamboo chopsticks to poke holes 3-4 from the mouth of the bag, or loosen the rope that holds the two ends of the bag a little loose. Use the natural tension of the bag mouth membrane after loosening the rope to allow fresh air to enter the bag. , To supplement oxygen by ventilation, to promote the healthy growth of mycelium.
