In spring, the outside temperature is relatively low, and the mycelium growth of Pleurotus ostreatus is slow, which affects the yield and benefits. To solve this problem, the following measures should be taken:

1. Increase lime: Increase lime usage to 5% when mixing. The pH of the mixed material is between 8 and 9 so that the growth of the bacteria can be inhibited and the mycelial growth rate can be increased.

2. Direct bagging: The raw material is mixed and then directly bagged without fermentation, so that the culture material in the bag generates more heat, thereby accelerating the speed of germination.

3, increase the inoculation amount: appropriate increase in the use of species when bagging, three-layer inoculation into four layers of inoculation. The intermediate bacteria should also be properly increased. The bacteria should stick to the plastic bag, 4 to 5 blocks in a circle. Bags at both ends of the bag can be slightly smaller, 6 to 7 pieces at each end. After tying, use a stick with a diameter of 10 to 12 mm to apply 4 to 5 vent holes at the ends of the bag. The depth of the holes is half of the length of the bag, so that the mycelium in the bag grows with enough oxygen. . Using this technology, the time for bacterial bag germs can be shortened from 30 to 35 days in the past to 15 to 20 days. The hyphae are thick and white, and the pollution rate can be controlled below 2%.

4, code heap bacteria: After the bacteria bag moved into the mushroom shed, the bacteria bag two to two stacked 6 to 8 high, covered with grasshopper insulation. Production practice has proved that the higher the stacking of the bacteria bags is, the closer the pile spacing is, and the higher the temperature between the piles. By adopting this stacking method, the temperature of the bacterial bag can be increased to 23 to 28°C. Mycelium grows at this temperature and is the fastest.

5, increase the temperature of the greenhouse: the mushroom shed is covered with semi-drip film and grasshopper. As long as there is the sun during the day, all the roofs are pulled open, and the temperature in the shed can reach 10-23°C depending on the sunshine.
