초록

큰느타리 대체 재료를 선발하고 자실체 생육특성을 확인하여 안정생산기술 농가 보급을 위한 기초자료로 활용하기 위해 본 연구를 수행하였다. 처리별 배지재료를 달리하여 제조한 배지 성분분석 결과 총탄소함량은 관행(40.86%)대비 처리구에서 42.24~48.22%로 높았고, 총질소함량도 관행(1.39%)대비 처리구에서 1.7~2.29%로 높은 것을 확인하였다. 탄소질소비율은 관행배지에서 27.9%로 가장 높았고 처리구는 19.12~27.88%로 차이를 보였다. 처리별 균사생장은 28일간 배양하였을 때 배지-1과 배지-6에서 11.5 mm와 11.3 mm로 가장 빨랐고, 관행과 배지-3, 배지-11은 10.1~10.3 mm로 유사하였으며, 균사밀도는 처리간 뚜렷한 차이를 보이지 않았다. 병당 수량은 관행배지(152.2 g/병)보다 배지-8(205.95 g/병), 배지-7(178.51 g/병), 배지-11(170.63 g/병)에서 많았다. 자실체 품질은 모든 처리에서 관행과 대등하였다. 위의 결과를 종합하여 배지재료 가격 등 경제적 효과를 분석하고 잔류농약, 유해미생물 등 안전성 연구를 수행하여 안전생산 및 안정생산 기술이 농가에 보급될 수 있도록 추후 면밀한 연구가 진행되어야 할 것으로 판단된다.

The present study aimed at selecting a cost-effective substrate for king oyster mushroom based on the growth characteristics of fruiting body for use as a basic resource to ensure stable production on farms. Compositional analysis of substrates manufactured with different materials in each process revealed that the total carbon content was 42.24-48.22% higher and the total nitrogen content was 1.7-2.29% higher in the processed lot than in the control (i.e., substrate used by the farmhouse; 40.86% and 1.39%, respectively). Meanwhile, the carbon-to-nitrogen ratio was the highest in the control (27.9% vs. 19.12-27.88% in the processed lot). When cultured for 28 days, the mycelium growth was 11.5 and 11.3 mm in substrates 1 and 6, respectively, indicating the fastest growth; meanwhile, the values were 10.1-10.3 mm in the control and substrate 11, showing a similar tendency. Mycelial density did not differ significantly among the processed lots. Yield per bottle was higher in substrates 8 (205.95 g/bottle), 7 (178.51 g/bottle), and 11 (170.63 g/bottle) than in the control (152.2 g/bottle). Fruiting body quality was comparable to controls in all processed lots. Overall, economic effects, such as substrate material prices, should be analyzed, and stability evaluations, such as residual pesticide and harmful microorganisms, should be undertaken along with further detailed examination to ensure safe and stable production on farms.
