Precautions for Managing Edible Fungi in High-Temperature Weather

First, strengthen shading, cooling and ventilation of the mushroom shed. Thicken the shed roof and add coverings on the sun-facing sides around the shed, and turn on exhaust fans for ventilation.

Second, use water spraying for cooling. Every morning or evening, spray water on the walls around the inside of the cultivation room, the air space, the floor, and the outside of the shed roof and its surroundings; where conditions permit, spray water on the shed roof for cooling. After spraying, be sure to strengthen ventilation to prevent high temperature and high humidity from causing contamination by foreign bacteria and resulting in rotten logs.

Third, move the fungus logs as little as possible and make as few holes for aeration as possible. If holes for aeration and moving the fungus logs are truly necessary, do so in small batches in the cool of the morning and evening.

Fourth, promptly deal with contaminated and discarded fungus logs. For small areas of rotten logs, dig out the rotten fungus blocks and then apply quicklime solution or a slightly higher-concentration fungicide to treat them, so as to prevent and control further spread of the pathogens. For fungus logs that exude yellow water and are partially contaminated, manage them separately from normal logs to avoid cross-infection. For fungus logs that have been completely suffocated and overheated, break open the bags and turn them out to dry in the sun as early as possible to reduce losses.

Fifth, maintain environmental hygiene and do a good job of pest and disease control. Promptly remove weeds, debris and other contamination sources around the mushroom yard; the surroundings of the mushroom shed can be disinfected with lime, bleaching powder and the like.

Sixth, strengthen inspections and pay attention to fire prevention. Smoking is strictly prohibited around the mushroom house; production materials should be stacked reasonably and kept ventilated to prevent spontaneous combustion; equip necessary fire-extinguishing equipment so that facilities and equipment are in place in case of an accident.
