Five empirical farmhouses were selected to reduce the high temperature damage in oak mushroom cultivation using bed-logs. The cultivation facilities were categorized as follows: those having two blackout curtains or one blackout curtain and outdoor oak mushroom cultivation. The inequality of the indoor condition, oak mushroom hyphae rampant ratio, and fruit body production in each test condition was evaluated. 3oC was lower in indoor temperature of cultivation facility having two blackout curtains than one blackout curtain. Specifically, the indoor air humidity average of cultivation facilities having one or two blackout curtains was 10% lower than that of outdoor oak mushroom cultivation. This condition is not ideal for oak mushroom cultivation as continuous indoor humidity control is essential for producing good fruit bodies. The Inoculated bed-log surface and oak mushroom hyphae rampant ratio of bed-logs cultivated with two blackout curtains was superior to other tested conditions. The mushroom production ratio observed in facilities with two blackout curtains was 117-204% higher than those cultivated in facilities with only one blackout curtain. Furthermore, the mushroom production ratio increased in based on these findings, we recommended five cultivation facility models to reduce high temperature damage in oak mushroom cultivation using bed-logs.

현재 우리나라의 표고 재배임가 대부분이 이상고온 등 재배환경 변화에 따른 피해로 표고균의 초기 활착불량과 버섯 생산성 및 품질 저하에 의한 큰 피해를 입고 있다. 시설재배사의 고온피해 경감을 위하여 대표적인 원목 1중(비닐․차광) 재배사 내부에 2중 차광망을 추가 설치하여 1중 재배사와 임내 재배장의 온습도, 균사활착 및 버섯생산성을 조사하였다. 고온성, 중온성 품종 재배시설(폭 7m, 동고 3.6m)의 '09. 8월중 최고온도를 비교한 결과 내부 지붕 2중 하우스가 27.2℃, 임내 재배장이 27.4℃로 1중 재배사보다 평균 약 3～4℃정도 낮았고, 저온성 품종 재배시설(폭 7.4m, 동고 3m)의 경우에는 평균 약 1～2℃정도 낮았다. 평균 습도는 최고온도와는 달리 임내재배장에 비하여 1중, 내부 지붕2중 차광 재배사 각각 79.5%, 80.6%로 임내 재배장(90%)보다 더 낮아 1중 재배시설이 고온 및 건조에 의한 피해가 매우 심각하였다. 버섯 생산성(저온성 품종)을 비교한 결과 내부 지붕 2중 차광 처리구의 본당 버섯 생산량이 866.3g으로 1중 재배시설 424g보다 2배 이상이었다.
