Abstract

This study was carried out to select the suitable for bag cultivation of Lentinula edodes. We investigated the optimal major materials and its mixing ratio in bag cultivation of L. edodes, 'Sanjo701ho' and 'Nongjingo'. The Suitable substrates for L. edodes bag cultivation were oak sawdust and douglas fir sawdust and rice bran mixed ratio 40:40:20(v/v). At the result, the period mycelial incubation shortened up to 13~18 days compared to the control. And Yield of commercial fruiting bodies was 17~19% higher than that in control. We expect that the cultivation period of L. edodes will be shortened, and the yield increased in the medium replaced half of oak sawdust by douglas fir sawdust.

봉지재배용 표고의 적합한 배지를 개발하고자 본 연구를 수행한 결과 참나무톱밥+미송톱밥+미강(40:40:20, v/v) 혼합배지인 T5에서 pH 5.3으로 대조구와 비슷하였으며 C/N율은 71.8로 대조구 85.2 대비 낮은 경향이었다. 배양특성은 T5에서 대조구 대비 산조701호는 13일, 농진고는 18일 배양기간이 단축되었다. 자실체 특성조사 결과 산조701호 품종에서는 T5에서 대조구 대비 갓이 크고 두꺼웠으며, 대도 길고 두꺼워 개체중이 높게 나타났다. 반면 농진고 품종에서는 대조구와 비슷한 경향이었다. 배지조성에 따른 혼합배지별 수량은 T5에서 대조구 대비 산조701호는 17%, 농진고는 19% 증수되었다. 이러한 연구 결과를 바탕으로 참나무톱밥의 50%를 미송톱밥으로 대체할 경우 배양기간이 단축되고 수량이 증수되며 또한 생산비 절감이 가능할 것이라 판단되었다.
