First, do a good job of mushroom house insulation and ventilation in the winter, mushroom room temperature is best kept at 3 °C above, do not make the indoor ice, to prevent freezing mycelium. In order to maintain this temperature in the mushroom house, before entering the winter season, the leaks at the four walls of the mushroom house should be checked and blocked one by one, and curtains should be hung on the doors and windows to prevent cold wind from intruding. At the same time, when the weather is warm, pay attention to ventilation and make the indoor air fresh. Ventilation method: open the south window of the mushroom house at noon for two or three hours; if the sky is warm and windless, and the outdoor temperature is above 8°C, open the south and north windows to allow air convection; if the outdoor temperature at noon is lower than 5°C Ventilation should be suspended.
Second, do a good job of mushroom bed water spray and fertilizer winter mushroom bed how much the number of water, depending on the degree of wet and dry soil particles, generally able to maintain moisture on the line. To prevent excessive water spray, too much, so that the bed surface is too wet, so as to avoid the freezing of mycelium germination at low temperatures. Mushroom top dressing can be combined with water spray. The top-dressing manure is best poured and filtered with gauze, with a concentration of about 20%. Unfiltered feces cannot be caught on the surface of the bed.
Third, do a good job bed root loose soil in addition to the old root should be based on mushroom house conditions and soil mycelium growth conditions may be. The mushroom house is in good condition and the mycelium grows vigorously in the soil layer. The mushroom bed fine soil can be scraped to loosen the coarse soil and the loose surface can be larger. The mushroom house conditions and the hyphae in the soil layer are generally grown without shading. Fine soil on the bed will loosen the coarse soil; if the mushroom room conditions and the mycelium growth in the soil layer is poor, winter can not loosen. Until the coming spring of March-April, it will be easy to move coarse and fine soil once. However, whether it is loosening coarse soil, or loosening coarse and fine soil, a large number of white mycelium cannot be peeled off, especially for the hyphae wrapped around the coarse soil. Otherwise, excessive exfoliation of mycelium will greatly affect the yield of spring mushrooms. When clearing the old root and dead mushroom of the mushroom bed, it is necessary to re-pave the coarse and fine soil and spread it. About one week after the last loose soil, when the mycelium has germinated, a new thin layer of 2--3 cm thick is to be placed on the mushroom bed. Before covering the soil, it is necessary to spray two or three times in combination with topdressing to make the coarse soil obtain moisture and nutrients so as to promote the germination and growth of the hyphae.
Many practices have proved that the winter management of the mushroom bed is done well, and the bumper harvest of the spring mushroom is certain.
