Management measures of Edible Fungi in Winter

The temperature is low in winter, the mycelium and fruiting body grow slowly, the respiration rate is low, the amount of mushroom is less, but the mushroom meat is thick and the quality is good. The vast number of mushroom farmers should seize the good opportunity of large market demand and high best-selling prices of winter mushrooms during the Spring Festival, and resolutely take measures to strive for more mushrooms, produce good mushrooms, and achieve better economic benefits. There are three specific management measures:

Raising the temperature of the mushroom bed and creating the conditions for growing mushrooms in cold winter can only be adjusted by natural air temperature combined with artificial adjustment. The shiitake shed removes the covering on the shed, and the film on the mushroom bed is tight for the rest of the time except for mushroom picking; the mushroom shed spreads out the cover on the shed; the mushroom shed is covered with a layer of film on the outside of the mushroom shed. Rely on the natural sunlight and the biological heat of the mycelium to maintain the temperature in the mushroom shed, and cover the outside of the shed with sunshade net or grass curtain to prevent frost and frost at night. Generally, after taking the above measures, the temperature in the greenhouse can be increased by 5 ℃-10 ℃, and the mushroom can still produce normally in the cold winter.

Replenish water to control humidity, warm and cold shiitake mushrooms, Pleurotus ostreatus through the growth of bacteria and autumn mushrooms, bacterial sticks lose more water, only 50% of the original weight, 60% of the original weight, water should be replenished at this time. Open the shed door for ventilation for 3 to 4 days before replenishing water, and insert the injection needle into the bacterial stick when replenishing water. With the help of the pressure of the water pump, the bacterial stick can absorb enough water in a short time, and the source of water should be well water. The principle of spraying water is: spray water, spray mushrooms more often, spray less mushrooms when less, spray more in bud period, and spray less in harvest period. Mushrooms do not need to be replenished and sprayed in winter.

Pay attention to ventilation, to avoid cold wind attack mushroom buds, exuberant breathing, if the air is not ventilated, carbon dioxide deposition is too much, it will inhibit the formation and growth of fruiting bodies. Ventilation should be carried out around noon when the temperature is high, and the time is 10-20 minutes. In and out of the shed operation, from the south side of the shed in and out, to prevent the dry cold wind attack.
