The appropriate temperature for the growth of the fruit body of Pleurotus eryngii is 14-16 degrees Celsius. When the mushroom room temperature is less than 10 degrees Celsius, it grows slowly or stops growing. In order to prolong the mushrooming time, it is necessary to try to increase the temperature of the mushroom house. In winter and in high-cold regions such as Xinjiang and Northeast China, heat preservation and warming are all required for the cultivation of mushrooms and vegetables. According to the existing mushroom house structure in our district, the following two kinds of simple and feasible thermal insulation technology can be used, which is more suitable. First, when the temperature is lower than 11-13 degrees Celsius, covered with a black plastic film at the top and around the existing mushroom house, and firmly fixed with a rope, in the original position to open the ventilation window, the film should be cut off accordingly, keep the usual ventilation Needs. Every day ventilation or water spray should be selected when the temperature is relatively high at noon. Each mushroom house is best to have 2-3 thermometers, placed in different locations in order to observe temperature changes. Focus on the top layer temperature. Once the top layer temperature exceeds 23 degrees Celsius, the ventilation window should be opened in time to ventilate the air to avoid high temperatures and affect the quality of the mushrooms. Second, in the mushroom house aisle to place a number of ceramic barrels or iron pot burning charcoal or coal (preferably coke) of the heat energy, the method must pay attention to safety when warming. One must guard against fires. Use charcoal or coal to move into the room after the open flame, and keep away from the sturdy wood frame. At the same time, you should not let the mattress mattress grass or other flammable materials approach. Second, to prevent carbon dioxide poisoning, every time before entering the house must first open the door, window for ventilation and ventilation before entering the room operation.
