Scope

Scope: This standard specifies the environmental requirements for the production of green food mushrooms, including site selection, production management techniques, pest and disease control, harvesting, fermentation management, and mushroom residue disposal. This standard applies to the cultivation of mushrooms in matured substrate bags in Yuanqu County. Main technical content: 4.6 Mycelium cultivation 4.6.1 Disinfection and sterilization of the mycelium cultivation room: Before using the mycelium cultivation room, first sprinkle lime powder on the floor at a rate of 200 g/m2, then disinfect with aerosol disinfectant at a dosage of 5 g/m3 for 40 minutes, with the room kept sealed during the process. 4.6.2 Temperature control: The temperature of the mycelium cultivation room should be maintained at 22°C–25°C, and the substrate temperature at 24°C–26°C. If the substrate temperature exceeds 28°C, cooling measures such as shading and ventilation should be implemented. 4.6.3 Ventilation: Ventilation should be combined with temperature control. When the temperature is high, ventilate in the morning and evening; when the temperature is low, ventilate from 10 am to 2 pm; and increase ventilation frequency when the substrate temperature is high. 4.6.4 Lighting: Maintain low light conditions to prevent mycelium from forming a film. Ten days before bag removal, increase lighting appropriately. 4.6.5 Treatment of contaminants: During daily pile turning, check for contaminants. For mild contamination, remove and disinfect the contaminated areas immediately and restart the process; for severe contamination, wrap the mycelium bags with wet cotton fabrics to control spore dispersion, then remove them from the cultivation room and bury them deeply away from the base. 4.7 Bag removal: When the mycelium has grown to a diameter of 5 cm, remove the bags to increase aeration. Stack the bags inverted, with the height of the stack not exceeding 8 layers. 4.8 Puncture a
