Abstract

To provide a basic information on the chemical concentrations of different raw materials used in mushroom cultivation, the raw materials were collected from 13 Flammulina velutipes, 14 Pleurotus eryngii, and 8 P. ostreatus farms and analyzed to calculate moisture contents, pH, total carbon(T-C), total nitrate(T-N), total phosphate(T-P) and 13 different cations. In our results, the C : N ratios of cotton seed meal, beet pulp, and corn-cob were 6~17, 12~29 and 56~127, respectively. Depending on the companies which process these materials, the range of C:N ratio of soybean curd residue was approximately either 8~9 or 14~17 with wider range of C : N ratio of the raw materials imported from other countries without the detection of heavy metals. In this study, the formula was provided to calculate the composition of mixed media for mushroom cultivation based on the ingredient chart of different raw materials.

본 시험은 버섯 병재배 농가에서 사용하고 있는 배지재료와 혼합배지의 수분함량, pH, 전탄소(T-C), 전질소(T-N), C/N율, 인산, 13종의 양이온 함량 등 이화학적 특성을 파악하여 기초자료로 활용하고자 수행하였다. 전국의 병재배 농가에서 임의로 선정한 35농가 중 팽나무버섯 13개소, 큰느타리버섯 14개소, 느타리버섯 8개소에서 배지재료 143점과 혼합배지 35점의 시료가 수집되었다. 배지재료의 성분함량은 동일한 명칭의 재료라도 2~5배로 차이가 많은 경우도 있었다. 그리고 농가에서 수집한 버섯재배용 혼합배지의 C/N율은 팽나무버섯과 큰 느타리버섯 배지가 $28{\pm}4$, 느타리버섯 병재배용 배지는 $21{\pm}2$의 범위이었으며 중금속 등 특정성분에 특이사항은 없었다. 그리고 배지재료별 성분함량표를 이용하여 버섯 재배용 혼합배지의 성분조성을 산출하기 위한 계산식을 제시하였다.
