총탄소함량은 T4를 제외한 모든 처리구에서 대등하였 으며, 총질소함량은 T3에서 2.17%로 대조구에 가장 근접 한 값을 나타내었다. C/N율은 T4에서 39로 다른 처리구 보다 높았다. 혼합배지에 따른 자실체의 생육특성을 조사 한 결과 갓직경은 T2에서 가장 컸고, 대직경은 T2와 T4 에서 가장 컸고, 대길이는 T1과 T2에서 가장 많았다. 유 효경수는 T1과 T3에서 가장 많았다. 혼합배지에 따른 처 리구별 수량은 T3에서 171g/병으로 대조구와 대등하였고, 회수율도 89.2%로 대조구와 대등한 결과를 나타내었다.

In this study, we attempted to find substitute materials, distillers residue of cassava, alfalfa pellet, and distillers residue of corn, for cotton seed meal in bottle cultivation of Pleurotus ostreatus. In all treatments, the total carbon content was comparable with the exception of T4, and the total nitrogen content of T3 was similar to the control group, and C/N ratio of T4 was higher than other treatments. The diameter of plieus was the largest in T2, and the diameter of stipe was the largest in T2 and T4. And the length of stipe was largest in T1 and T2, and the most number of available stipes was in T1 and T3. The yield and bio-efficiency of fruit-body by residue of corn with soluble treatment(T3), were similar to the control of P. ostreatus. Therefore, it was suggested that residue of corn was substituted for cotton seed meal for cultivation of P. ostreatus.
