Summer management for substrate logs: outdoor shade houses ventilate and cool readily, helping reduce overheating during colonization. The following measures are used for outdoor summer incubation.
First, grow climbing crops such as pumpkins or gourds on frames around the shade house to improve shading.
Second, install rotating sprinklers or mist pipes above the house and spray between 10 a.m. and 4 p.m. for cooling.
Third, dig connected trenches 20 cm wide and 30 cm deep around the house and along aisles, running water through them for cooling. Indoors, add shade; close doors and windows around midday to retain coolness, reopen in the evening for ventilation, and use water basins and fans at noon.
Fourth, spray water on the roof to cool the building and keep indoor relative humidity at around 70%.
Before hot weather, spread or relocate inoculated logs to a well-ventilated, heat-dissipating site. Do not turn logs during high temperatures, since disturbance can increase mycelial respiration, raise stack temperature and cause overheating.
Do not cut or perforate bags during extreme heat: incoming air can increase respiration and stack temperature. Inspect frequently and remove and disinfect rotten logs promptly to limit spread.
At an early stage of substrate-log rot, remove the affected patches. Coat the exposed area with a paste of quicklime and water for disinfection.
