Winter and spring mushroom house management essentials

The variety and quantity of fresh vegetables decreased in winter, and edible fungi began to sell well in the market. The management of overwintering mushroom house should be strict, and a little carelessness will cause greater losses.

When the temperature of the mushroom room for cultivating edible fungi dropped below 10 ℃, the production of autumn mushrooms was over and entered the overwintering management period. During this period, the soil particles in the mushroom bed were mainly prevented from being too dry, the hyphae withered and the indoor exhaust gas too much, freezing to death bacteria, resulting in a reduction in the production of spring mushrooms in the coming year.

Spraying water and topdressing fertilizer regularly and quantitatively. Dry climate in winter, large evaporation on the bed, in order to facilitate the soil particles to maintain temperature, generally spray water once every 5 li 7 days, watering 150 grams per square meter, so that the fine soil does not whiten, can be pinched, can be rubbed. Avoid using too much water, lest the newly germinated hyphae suffer frost damage, or because there is too much stagnant water, affect ventilation and cause miscellaneous bacteria infection. Spraying water at the same time combined with topdressing, farm manure can be used, the concentration is between 20% and 30%, or 1% glucose solution can be sprayed to improve the cold resistance of mycelium.

Keep warm and ventilated. The room temperature of overwintering mushroom should be kept above 4 ℃ and strictly prevent freezing. If the room temperature is too low, do not light the stove indoors to prevent excessive concentration of carbon dioxide and inhibit the growth of mycelium. In addition to building wind barriers and hanging straw curtains on doors and windows, electric heating can be used, electric radiators and so on. Properly ventilated at noon on a sunny day, we can take the method of leaving air holes on the window to remove harmful gases and keep the indoor air fresh.

Loosening the soil once before the Spring Festival and removing the old roots can improve the aeration condition of the overlying strata and promote the growth of new hyphae. Stop spraying water 7 days before loosening the soil, then remove the upper fine soil, loosen the coarse soil, and remove the yellowing old hyphae and dead mushrooms in the soil layer. Do not touch the white hyphae near the coarse soil, so as not to affect the production of spring mushrooms, use thick wooden sticks to pierce holes from the opposite side of the fungus bed, do not touch the surface coarse soil. Loosen the soil layer to flatten the slope and fertilize it again as appropriate.
