Technical measures for heat preservation of mushroom house in winter
The suitable temperature for fruiting body growth of Agaricus bisporus is 14 Mel 16 degrees Celsius. When the temperature of the mushroom room is lower than 10 degrees Celsius, the growth is slow or stops. In order to prolong the time of mushroom production, we must try to increase the temperature of the mushroom room. Growing mushrooms and vegetables in cold areas in winter should be kept warm and warmed up.
First, when the temperature is lower than 11Mel 13 degrees Celsius, cover the top and surrounding of the existing mushroom room with black plastic film and fasten it firmly with rope. In the original position of the ventilation window, the film should be cut off accordingly to retain the need for ventilation. Daily ventilation or water spraying should be carried out when the temperature is relatively high at noon. Each mushroom house had better have 3 thermometers of 2mi, placed in different locations in order to observe the temperature change. Focus on the top temperature. Once the top temperature exceeds 23 degrees Celsius, you should open the ventilation window in time so as not to cause high temperature and affect the mushroom quality.
Second, in the aisle of the mushroom room, put a number of ceramic buckets or iron pots to hold the heat of burned charcoal or coal (preferably coke) to increase the temperature, this method must pay attention to safety. First, it is necessary to strictly guard against fire. Use charcoal or coal in the open fire before moving into the house, and away from the mushroom bed wooden frame, but also do not let mushroom mattress grass or other combustible materials close. Second, to prevent carbon dioxide poisoning, you must open the door and window before entering the room before you can enter the room.

The benefit of planting Agaricus bisporus in winter fallow rice field is good.
In 2004, our county conducted a cultivation demonstration of growing Agaricus bisporus in winter fallow rice field in 16 towns. after late rice harvest, rice straw was used as the main raw material through composting fermentation as culture material, making use of the temperature and light resources in winter and the idle season in paddy field in winter. Obvious benefits have been achieved in open field cultivation of Agaricus bisporus. Chen Yeru, a farmer in Lixian Institute of Agricultural Sciences, is a demonstration household for the cultivation of Agaricus bisporus, a family of 4 people and 2 labourers, who have never cultivated edible fungi before. After technical training from Lixian Edible Mushroom Research Institute, he set up in his own contracted field.

Don't forget to control six major diseases of mushrooms in winter
Brown rot diseased mushrooms were infected when young, unable to differentiate, and irregular gray-white "goose heads" were formed in the later stage, such as the mushroom lid was as thick as fist, or the stipe cap was difficult to distinguish, and a layer of "white hair" was planted on the surface. When the temperature was above 20 ℃, the diseased mushroom color darkened in 4 to 5 days, then rotted, oozed brown and soy sauce, and rotted and stinked; if the greenhouse temperature was lower than 20 ℃, the process became longer, about 7 days. If the fruiting body is infected in the middle stage of growth, the brown spot appears on the surface of the cap, and the stalk is chubby, followed by the mushroom body.
