Key points of Management Technology of Edible Fungi in Winter

It is understood that the winter temperature is cold, the mycelium and fruiting body grow slowly, the respiratory intensity 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. In management, we should focus on the following points:

First, raise the temperature of the mushroom bed and create conditions for growing mushrooms. Cold winter, the natural temperature is not conducive to mushroom production, sunny morning can remove the cover on the shed, rely on natural sunlight and mycelia of their own biological heat to increase the temperature in the mushroom shed. In cloudy days and at night, sunshade nets or grass curtains should be added to prevent frost and frost outside the shed, and there are conditions to cover a layer of film outside the shed, so the heat preservation effect will be better. After taking the above measures, the temperature in the greenhouse can be increased by 5 Murray for 10 ℃, and the mushroom can still grow normally in the cold winter.

Second, replenish water and control humidity, keep warm and prevent cold. After producing a crop of Lentinus edodes, the stick loses more water, and only 50% of the original weight is 50%, so water should be replenished at the right time. Open the shed door for ventilation for 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 water source should be clean and warm 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.

Third, pay attention to ventilation to avoid the attack of cold wind. After the mushroom bud occurs, the breathing is exuberant. If the air is not ventilated and the carbon dioxide is deposited too much, it will inhibit the formation and growth of the fruiting body. Ventilation and ventilation should be carried out around noon when the temperature is high, and the time is 10 Murray for 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.
