After the harvest of autumn mushrooms is over, if no warming measures are taken to continue the production of winter mushrooms, the mushroom bed will enter the winter management stage. In general, we must do the following:
Insulation and ventilation During the winter season, the room temperature of the mushroom house is preferably kept above 3°C to prevent freezing of mycelium. First of all, we must check and block the air leakage at the four walls of the mushroom house. We must put curtains on the doors and windows to prevent cold wind from invading. Second, in the warmer days, pay attention to ventilation and make the indoor air fresh. Ventilation method: open the mushroom house south window at noon for 2 to 3 hours; if the weather is warm and windless, and the outdoor temperature is above 8°C, open the south and north windows to allow air convection.
The number of water sprays and top-dressing of winter mushroom-bowl sprays depends on the degree of dryness and wetness of soil particles. Generally, it can be kept moist. To prevent excessive water spray too much, the bed surface is too wet, so that germination of mycelium at low temperatures suffered freezing injury. Mushroom dressing can be combined with water spray.
The loose soil in addition to the old root mushroom room conditions are good, the mycelial growth in the soil layer is strong, you can scrape the mushroom bed fine soil, loose loose soil, loose surface can be larger; mushroom room conditions and soil mycelial growth in general , do not have to scratch the fine soil on the bed to loosen the coarse soil can be; if the mushroom room conditions and soil mycelial growth is poor, the winter can not loosen, until the spring of March to April spring before mushrooming, the rough, fine Earth is easy to move once. After clearing the old root of the mushroom bed and the dead mushroom, it is necessary to re-pave the coarse and fine soil and spread it. After the last loose soil, cover a new layer of fine soil on the bed of the mushroom, 2 to 3 cm thick. Before covering the soil, it is necessary to combine 2 to 3 times of spray fertilizer.
