Technical essentials for Pleurotus ostreatus
After the mushroom shed is disinfected, the picked-up bag is transported to the mushroom shed for stacking and germination. The level of stacking depends on the temperature. When the temperature is high in summer and autumn, 2-4 layers are piled up. The bags are piled up in a “#†shape, which is cross-discharged to facilitate heat dissipation and leave the roadway. When the temperature is low in spring and winter, the bed is low. A layer of straw or wheat straw should be laid, stacked 10-12 layers, and covered with plastic film or straw curtain to increase the temperature of the heap and promote the growth of mycelium.
The main points of the management of the bacteria are:
First, keep the temperature, periodically insert a thermometer between the bags, pay attention to the temperature change of the pile. The temperature of the bacteria should be 25 °C - 30 °C. When the temperature is higher than 30 °C, it should be piled up in time to increase the ventilation and prevent the high temperature from burning the hyphae. When the temperature is lower than 20 °C, try to increase the temperature and keep warm.
The second is ventilation and ventilation: the mushroom shed is ventilated 2-3 times a day for 30 minutes each time. When the temperature is high, it will be ventilated in the morning and evening. When the temperature is low, it will be ventilated at noon.
The third is to keep dry, the relative humidity of the air in the mushroom shed is 60%-70%.
Fourth, the light is dark, and weak light is good for mycelial growth.
The fifth is to turn over. After stacking, turn it every 5-7 days, and put the lower layer of the bag up, the upper layer of the lower layer, the inside and the outside, and the outside to the inside, so that the temperature is consistent and the bacteria are neat.
Six is ​​ventilation and oxygen supplementation. In the early stage of germination, the oxygen content in the bag can meet the needs of mycelial growth. As the growth of mycelium increases, the oxygen content in the bag is insufficient, which will affect the normal growth of mycelium. .
10-15 days after inoculation, when the two hyphae in the bag are fed 2-3 cm in length, the needles can be pierced 8-10 times around the fungus bag at a distance of 1-2 cm at the back of the mycelial growth line. Or use the sharpened bamboo chopsticks to puncture the hole 3-4 from the mouth of the bag, or loosen the rope tightly at both ends of the bag, and use the natural tension of the film of the back of the slack to allow fresh air to enter the bag. To ventilate oxygen to promote the growth of mycelium.
