Abstract

This study was conducted to investigate a suitable substrate formulation for bag cultivation of Hypsizygus marmoreus. To determine the optimum media composition for H. marmoreus, chemical properties of various media and culture properties were investigated. The fastest primordia formation (9.0 days), the shortest fruiting body harvest period (18.0 days), and the highest yield (144.7 g/bag) were realized with the T6 formulation (55:15:20:5:5 mixing ratio of poplar sawdust, wheat bran, rice bran, dried soybean powder, and palm kernel, respectively). The chemical properties of the T6 formulation were pH, 6.0; total carbon, 19.0%; total nitrogen, 0.83%; C/N ratio, 22.8; P2O5, 0.61%; K2O, 0.46%; and MgO, 0.29%. This is the first attempt using plastic bags for cultivation and will help expand the production of H. marmoreus.

느티만가닥버섯 '햇살' 품종에 대한 봉지재배 안정생산 재배기술을 개발하기 위하여 포플러(미루나무) 톱밥을 주배지로 하고 밀기울, 미강, 건비지, 면실박, 팜커널등 5종의 영양원배지 재료를 혼합하여 배지를 조성하여 재배시험을 수행하였다. 배지혼합 전 재료들에 대한 열수추출 배지들에 대한 버섯균사 생장은 팜커널에서 가장 우수하였으며 균사밀도의 경우 포플러배지를 제외하고 모두 우수하였다. 조성배지들에 대한 버섯발생 안정성, 재배기간, 수량성을 기준으로 조사한 결과 포플러톱밥, 밀기울, 미강, 건비지, 팜커널이 55:15:20:5:65(v/v) 수준으로 조합된 T6배지에서 생육기간이 단축되고 수량이 높아 봉지재배에 적합한 배지로 선발하였다. 선발배지에 대한 균사배양 완료기간은 38.0일로 대조로 이용된 T1배지에 비하여 1.7일 더 소요되었다. 그러나 균긁기 이후 수확시까지 소요되는 기간은 18.0일로 대조배지(T1)를 이용한 재배기간보다 1.0일 단축됨에 따라 총 재배기간은 68.0일이 소요되었다. 선발배지에 대한 수량은 144.7 g으로 대조배지(T1) 수량 112.5 g보다 약 28.6%가 증가되었다. 이상의 연구결과를 통해 느티만가닥버섯 '햇살' 품종의 봉지재배 적합배지로 포플러톱밥, 밀기울, 미강, 건비지, 팜커널이 55:15:20:5:5(v/v) 비율로 혼합된 배지조성을 선발하였다. 선발배지에 대한 이화학적 특성으로 수분함량은 60.8%, pH 6.0, 전질소 함량은 0.83% 수준이었다.
