Abstract

This study was carried out to develop a new method of cultivation of 'Hwadam' a new variety of Lentinula edodes, to improve fruiting body productivity and reduce labor. To determine the optimum filter number for box cultivation, L. edodes were assessed for their cultural characteristics and mushroom yield. During spawn running of L. edodes in the box, the temperature gradually increased to the highest value of 25.8℃, 23.7℃, and 23.0℃ on day 18 for the four filter, two filter, and no treatment groups, respectively. Oxygen concentration displayed an opposite trend to carbon dioxide concentration, reaching the lowest value on day 21. The oxygen concentration progressively increased as more filters were used (5.4%, 8.2%, and 8.9% treatment with no, two, and four filters, respectively. Growth of L, edodes in the box resulted in the highest yield (2,228 g/7kg substrate) and biological efficiency (70.7%) using four filters. The biological efficiency of the four filter treatment was 29.4% higher compared to bag cultivation (41.3%). Further studies are necessary to verify stable productivity of fruiting bodies through repeated cultivation.

표고 생산성 향상을 위해 상자재배를 실시하고 필터처리에 따른 효과를 구명하고자 수행한 결과는 다음과 같다. 배양기간에 따른 상자내부의 온도는 서서히 상승하여 18일째 최고치에 도달하여 필터4구가 25.8℃, 필터2구가 23.7℃, 무필터구가 23.0℃로 필터수가 많을수록 온도상승이 크게 일어났다. 상자내부 CO2 농도는 온도 변화와 같은 패턴으로 배양 기간이 경과에 따라 증가하다 배양 24일째 최고치에 도달하였으며, 무필터구가 17.2%, 필터2구가 14.9%, 필터4구가 14.4%로 필터수가 많을수록 CO2농도는 낮았다. O2농도는 배양21일째 최저치에 도달하였는데 무필터구 5.4%, 필터2구가 8.2%, 필터4구가 8.9%로 필터수가 많을수록 O2농도도 높았다. 재배특성은 처리구와 상관없이 배양기간은 34일, 갈변기간은 57일 이었으며, 재배기간은 무필터구가 108-111일, 필터2구가 105-111, 필터4구가 102-111일로 각각 나타났으며 봉지재배의 110일과 유사하였다. 필터 처리에 상자재배의 3주기 수량성은 필터4구가 2,228 g, 필터2구가 1,880 g으로 무필터구의 894g에 비해 유의적으로 우수하였다. 3kg 봉지재배와 비교시 필터4구 상자재배의 생물학적 효율이 70.7%로 봉지 재배 41.3%보다 29.4% 높은 것으로 나타났다.
