Heat preservation method of Pleurotus ostreatus cultivated in winter

The success rate of cultivating Pleurotus ostreatus in winter is high, and it is also a good time for people to make use of their spare time to get rich. However, when the temperature is low in winter, the bacteria of cultivated Pleurotus ostreatus are slow or delayed, and abnormal mushrooms are produced during the period of mushroom production. Heating with coal stove will not only increase the cost, but also cause poisoning of mushroom body. In practice, I created the method of biological energy preservation of Pleurotus ostreatus planted in winter, which has the advantages of cost saving and hygiene.

1. Pleurotus ostreatus should be cultivated with bag material in late autumn. A Pleurotus ostreatus bag with half a bag of hyphae for heat preservation is provided when the temperature is cold. If there is no bag material cultivation in advance, one-time heating can be carried out to cultivate bacteria.

2. After the air temperature is very low, adopt the bacterial bag password, code height, code width, easy to gather temperature, increase temperature, heat preservation. The method of stacking is: each yard is divided into four rows, each row is 7 bags high, and there is a gap of about 50 centimeters between each row to facilitate air exchange. The distance between each section is 67 cm, which is convenient for people to walk, manage and turn over the heap. Finally, cover 2 layers of whole plastic film.

3. The newly received bacteria bag is stacked with the heat preservation bag. First, the bag with half a bag of hyphae on the third layer of the low-level code, and the bag of freshly received bacteria on the top four layers. And then covered with plastic film.

4. Pay attention to check the temperature every day. The bacteria bag will produce heat in the process of sterilization. When the temperature is 27 ℃, the film should be opened to control the temperature. When the mycelium is full, take it out immediately and discharge it to the mushroom place to produce mushrooms. Then code the newly inoculated bacterial bag on the bacterial bag that is not yet full of bacteria, cover the film and keep warm for culture. In this way, the full bacteria bags are taken out one after another and filled with new bacteria bags.

5. Take out the bag full of mycelium and transfer it to the mushroom field (indoor or shed, etc.) to discharge the mushroom. The coding method is as follows: each row of code is 7 layers high, the code is straight against toppling, the spacing between each row is 40 cm, a large spacing is left in 3 rows, and then 3 rows are connected, and the large spacing is 70 cm, which is convenient for people to walk, manage and pick mushrooms, and shake hands on both sides. In case of very low temperature, you can cross the thin bamboo pole on the whole Pleurotus ostreatus chop and cover it with plastic film to keep warm. When the temperature is high, you can open the window to breathe and keep the air fresh. Other management methods follow the routine.
