Detailed Explanation of Technical Measures for Safely Overwintering Shiitake Mushroom Logs Through Summer

Key Management Points for Safely Overwintering Mushroom Logs Through Summer. Outdoor summering. Outdoor shade shelters have good ventilation and cool down quickly, therefore, using outdoor shade shelters for mycelium running can effectively reduce the occurrence of "mushroom burning." Specific measures taken for summering and mycelium running using outdoor shade shelters: First, build trellises around the shade shelter and plant vine crops such as pumpkins and luffa to improve the shading effect; Second, install automatic rotating tap water sprinklers or spray pipes on the shelter roof, and spray water to cool down from 10 AM to 4 PM every day; Third, dig interconnected trenches 20 cm wide and 30 cm deep around the inside of the shelter and on both sides of the walkways, and run flowing water through the trenches to cool down. Indoor summering. Various measures should be taken to cool down. First, add shading facilities around the inside of the room; Second, close the doors and windows of the room around midday on sunny days to keep the room cool and shady, and promptly open the doors and windows in the evening for ventilation and heat dissipation; Third, place basins of water in the room at noon and use electric fans for ventilation and heat dissipation; Fourth, the roof can be sprayed with water to lower the temperature, and the relative humidity inside the room should be maintained at around 70%.

Precautions During the Mycelium Running Process. For inoculated mushroom logs, before the high-temperature season arrives, a site with good ventilation and heat dissipation conditions should be selected to complete the work of breaking up and relocating the log piles. During high temperatures, it is strictly forbidden to turn or move the mushroom logs, to prevent the logs from being vibrated, which would increase mycelial respiration and raise the pile temperature, causing "mushroom burning." During high temperatures, it is forbidden to cut the bags or puncture holes in summering mushroom logs, to prevent air from entering the interior of the logs, which would increase mycelial respiration and raise the pile temperature, causing "mushroom burning." During the mycelium running period, frequent inspections should be carried out. Once rotten logs are found, they should be promptly handled and disinfected to prevent the spread of pathogens and resulting losses. Generally, in the early stage of mushroom log infection and rot, the method of digging out the rotten blocks and spots can be used for handling. After handling, mix quicklime with an appropriate amount of water into a paste and apply it to the wound for disinfection.
