초록

외화유출 감소와 버섯의 생산 단가를 절약하여 농가소득을 증대시킬 목적으로 폐 한방슬러지를 첨가한 배지에서 팽이버섯을 배양할 때 버섯재배를 위한 최적 생육환경 조건을 검토하였다. 그리고 최적 생육한경 조건에서 생산된 팽이버섯 자실체의 특성을 조사하였다. 폐 한방슬러지의 첨가농도는 10%가 적당하였고, 배지의 함수율은 폐 한방슬러지를 첨가하지 않은 대조구와 비슷한 약 65%가 적당하였다. 배양실 내의 온도는 $16^{\circ}C$, 습도는 75%~85%로 설정한 시험구에서 가장 왕성한 균사성장이 이루어졌다. 1,100 ml의 버섯재배용 병을 사용하여 현장실험을 행한 결과 병당 팽이버섯의 수확량은 대조구 및 시험구에서 약 275~282 g으로 거의 비슷하게 얻었다. 흰곰팡이 및 세균성 갈색무늬병 등 버섯질병의 발생은 전혀 관찰할 수 없었다. 그리고 기형버섯 및 2등품버섯 등이 약간 발생하기는 하였으나 전보에 비하여 그 편차가 줄어들어 상당히 균일한 버섯의 생육을 관찰하였다. 팽이버섯 자실체는 백색의 반구형으로 갓의 직경은 약 9.2~9.3 mm, 대의 길이는 약 12.7~12.8 cm, 뚜께는 3.3~3.4 mm로 대조구의 버섯품질과 거의 유사하였다. 버섯부위별 경도는 대조구와 시험구 모두 갓 부분($46.8{\sim}47.6g/cm^2$)보다는 대 부분의 경도($54.6{\sim}57.3g/cm^2$)가 약간 높은 것으로 나타났다. 트랜스지방 및 콜레스테롤은 검출되지 않았으며 100 g당의 열량 및 영양성분은 대조구와 거의 비슷하게 나타났다.

This study aims to reduce the production cost of mushrooms and therefore boost the income of mushroom producers. The addition of a 10% concentration of herb medicine refuse was adequate for promoting mycelium growth in Flammulina velutipes. A moisture content of 60% in the culture medium was adequate for promoting hyphal growth. The optimum temperature and humidity were $16^{\circ}C$ and 70%-85%, respectively. The average yield of Flammulina velutipes fruting body per 1,100 ml bottle was 275-282 g, which is similar to that of the control. The outbreak of diseases such as mildew and bacterial blotch in mushroom was never observed in the bottle treated with herb medicine refuse. Fewer deformed and second-class quality mushrooms were observed than in the control group. Deviation reduced, and mushroom growth was observed to be significantly uniform. The winter mushroom had a white fruiting body with a hemispherical shape. The diameter of the mushroom cap was 9.2-9.3 mm, stipe length was 12.7-12.8 cm, and thickness was 3.3-3.4 mm; these were almost the same as those in the control group. The partial hardness of winter mushrooms in both the experimental and the control groups showed that the stipe ($54.6-57.3g/cm^2$) is a little harder than the mushroom cap ($46.8-47.6g/cm^2$). The calories and nutrients per 100 g of mushrooms in the control and samples were similar to each other.
