How to manage edible mushrooms in winter? Remember these three key elements

Humidity: replenish water and control moisture, keep warm and prevent cold. After the spawn-running and autumn growth stages, shiitake (Lentinula edodes) and oyster mushroom (Pleurotus ostreatus) logs lose a lot of water, retaining only 50%-60% of their original weight, so water should be replenished in time. Before replenishing water, open the shed doors for ventilation for 3-4 days. When replenishing, insert water-injection needles into the logs and use the pressure of a water pump to let the logs absorb enough water in a short time; well water is preferable. The principle for spraying water is: spray as a fine mist, spray more when there are many mushrooms and less when there are few, spray more at the bud stage and less at the harvest stage. Mushrooms (Agaricus bisporus) basically do not need water replenishment in winter.

Air: pay attention to ventilation and air exchange, and avoid cold wind damage. After mushroom buds appear, respiration is vigorous; if the air does not circulate, carbon dioxide accumulates too much, which inhibits the formation and growth of fruiting bodies. Ventilation and air exchange should be carried out around noon when the temperature is higher, for 10-20 minutes. When entering and leaving the shed for operations, enter and exit from the south side of the shed to prevent damage from dry, cold wind.
