Rapid inoculation technique of Pleurotus ostreatus in spring

The mycelium of Pleurotus ostreatus grows slowly when the temperature is low in spring. Measures such as increasing the amount of lime, directly bagging, increasing the amount of inoculation, porous oxygen ventilation, stacking bacteria, increasing greenhouse temperature and regular stacking can be taken to ensure the success of bacteria. Generally, the mycelium is full of bags in 20 days, budding in about 1 month, and fresh mushrooms can be harvested and put on the market in about 35 days.

1. When the amount of lime is increased, the amount of lime is increased to 5%, and the pH value of the culture material is 8: 9, so as to inhibit the growth of miscellaneous bacteria and improve the growth rate of mycelium.

two。 If the raw meal is directly bagged and then bagged without fermentation, the culture material in the bag can generate more heat and accelerate the speed of bacteria generation.

3. When increasing the amount of inoculation, the amount of inoculation should be increased appropriately, and the inoculation should be changed from three layers to four layers. The fungus in the middle can be larger, which is close to the plastic bag and inoculated with 4 ~ 5 pieces in a circle. The bacterial clumps at both ends of the bag can be smaller, inoculated with 6 ~ 7 pieces at each end.

4. After the porous aerated bacteria bag is ligated, 4 ~ 5 ventilation holes are tied with sticks with a diameter of 10 mm ~ 12 mm at both ends of the bag, and the hole depth is half of the length of the bag to ensure an adequate supply of oxygen for mycelium growth in the bag. In this way, the time of producing bacteria can be shortened to 15 ~ 20 days, and the hyphae are stout and white, and the contamination rate is less than 2%.

5. Stack the bacteria in the mushroom shed and stack the bags side by side for 4 ~ 6 layers and cover with grass to keep warm. In this way, the temperature of bacterial bag can be raised to 23 ℃ ~ 28 ℃, and the mycelium grows fast.

6. Raise the temperature of the greenhouse and cover the mushroom shed without dripping film and grass. On a sunny day, the canopy was opened during the day, and the temperature in the shed was raised to 20 ℃ ~ 23 ℃. The bacterial bag should always be covered with herbs to ensure that the bacteria are spread in the dark to make the hyphae stout and white.

7. During the period of regularly stacking bacteria, insert the thermometer into the middle layer of bacteria bag. When the temperature reaches 30 ℃, it should be palletized and ventilated to cool down to avoid burning bacteria. Even if the temperature of the material is less than 30 ℃, it should be stacked every 3 ~ 5 days. Adjust the upper and lower layer material bag and the two ends of the bag to make the temperature of the upper and lower bag and the water content in the bag consistent, so as to promote the rapid growth of mycelium.
