Last Updated: 2024/11/06, In the Yangtze River valley and the northern provinces, such as Shanghai, Zhejiang, Jiangsu, Sichuan, Anhui and Northeast China, due to the cold winter, the temperature of the mushroom house is below 5 ℃, which is not suitable for mycelium growth, and the hyphae are dormant and unable to supply nutrients for fruiting body growth, so mushrooms will not grow. Generally from late December to early March of the following year, mushrooms are in the overwintering stage. Doing a good job of overwintering management is a necessary condition for high yield of Pleurotus ostreatus. (1) preparation before overwintering ① after the end of the autumn mushroom, the bed should be made first.

In the Yangtze River valley and the northern provinces, such as Shanghai, Zhejiang, Jiangsu, Sichuan, Anhui and Northeast China, due to the cold winter, the temperature of the mushroom house is below 5 ℃, which is not suitable for mycelium growth, and the hyphae are dormant and unable to supply nutrients for fruiting body growth, so mushrooms will not grow. Generally from late December to early March of the following year, mushrooms are in the overwintering stage. Doing a good job of overwintering management is a necessary condition for high yield of Pleurotus ostreatus.

(1) preparation before overwintering

After the end of ① autumn mushrooms, the first thing to do is to clean up the bed, pick out the old roots and dead mushrooms, fill up some soil where the hyphae are exposed, and then fight against the cuttings.

② does a good job in the heat preservation of the mushroom house, plugging all the oil leaks and hanging thick curtains on the doors and windows.

(2) overwintering management

① temperature: it is necessary to make full use of the doors and windows of the mushroom house and the external air temperature conditions to do a good job of heat preservation of the mushroom house. Specific method: on a sunny day when the sun is sufficient and the external temperature is higher than the temperature of the mushroom room, the south doors and windows can be opened from 10:00 to 2 pm; in the simple mushroom room, the grass curtains on both sides can be opened appropriately to facilitate external heat to enter the mushroom room. Conditional units, the mushroom room can be installed with smoke exhaust pipe coal stove or sawdust furnace to heat up, to increase the temperature of the mushroom room.

② moisture: fermented soil and fine mud bran soil covering materials should be wet in winter, that is, every 10 to 15 days, properly spray water on the soil layer. Spraying water should be carried out when the external temperature is higher than the temperature of the mushroom room. Water spraying can be carried out with well water or warm water of about 20 ℃, spraying 0.9-1.35kg per square meter each time. Do not spray water below 0 ℃.

③ air: during the mycelium overwintering, the requirement for air is relatively low, and the air conditioning of the mushroom room can generally be combined with the heat preservation work of the mushroom room.

④ topdressing: combined with the water transfer of the soil layer during overwintering, some nutrient solution can be sprayed on the soil layer to increase the nutrition of the mycelium of the soil layer. Topdressing solution can use 0.1% 0.2% urea solution.
