Winter management of mushroom bed

After the harvest of autumn mushrooms, if we do not take measures to increase temperature and continue to produce winter mushrooms, then the mushroom bed will enter the winter management stage. The management of the mushroom bed in winter will have a great impact on the mushroom harvest in the coming spring. Therefore, we must do a good job in the winter management of the mushroom bed.

First, do a good job in the heat preservation and ventilation of the mushroom room in winter, the room temperature of the mushroom room had better be kept above 3 ℃, so as not to freeze the room, so as to prevent the mycelium from freezing. In order to maintain this temperature in the mushroom room, before entering winter, the air leakage on the four walls of the mushroom room should be checked and blocked one by one, and the doors and windows should be hung with curtains to prevent the cold wind from invading. At the same time, on warm days, we should pay attention to ventilation to make the indoor air fresh. The method of ventilation: open the south window of the mushroom room at noon for two or three hours; if the weather is warm and windless, and the outdoor temperature is above 8 ℃, you can open both the south and north windows to allow air convection; if the outdoor temperature is lower than 5 ℃ at noon, ventilation should be suspended.

Second, to do a good job of spraying water on the mushroom bed and topdressing the mushroom bed in winter depends on the degree of dryness and wetness of the soil particles, and it is generally enough to keep it moist. To prevent spraying water too frequently, too much, so that the bed is too wet, so as to avoid freezing damage to the hyphae that germinate at low temperature. Topdressing of mushroom bed can be combined with water spraying. The manure had better be boiled and filtered with gauze with a concentration of about 20%. You can't chase unfiltered dung onto the bed.

Third, to do a good job of loosening the soil on the bed and removing the old roots should be determined according to the conditions of the mushroom room and the mycelium growth of the soil layer. If the condition of the mushroom room is good and the mycelium grows vigorously in the soil layer, the fine soil of the mushroom bed can be scraped off, the coarse soil can be loosened, and the loose surface can be larger; if the mushroom room condition and the mycelium growth in the soil layer are general, it is not necessary to scrape off the fine soil on the bed and loosen the coarse soil; if the mushroom room condition and the mycelium growth in the soil layer are poor, the soil can not be loosened in winter. The coarse and fine soil will be gently loosened before the mushrooms are produced in the spring from March to April next year. However, whether it is loose coarse soil, or loose coarse and fine soil, can not peel off a large number of white hyphae, especially the hyphae wrapped around the coarse soil should be paid more attention. Otherwise, the mycelium will peel off too much, which will greatly affect the yield of spring mushrooms. When removing the old roots and dead mushrooms in the mushroom bed, the coarse and fine soil should be paved and paved again. About a week after the last loosening of the soil, when the mycelium has germinated, cover the mushroom bed with a new thin layer, 2mm thick and 3cm thick. Before covering the soil, it is necessary to spray water combined with topdressing for two or three times to make the coarse soil get water and nutrients to promote the germination and growth of hyphae.

Many practices have proved that if the winter management of the mushroom bed is done well, the bumper harvest of spring mushrooms will be assured.
