Abstract

본 실험은 다양한 농가부산물들이 노루궁데이버섯의 재배를 위한 기질로써 적합한지를 알아보기 위하여 실시되었다. 이를 위해 참나무 톱밥, 사탕수수박, 코코낫박, 율무박, 왕겨, 배추, 면자각의 기본 기질들과 미강, 옥수수박의 첨가물을 서로 다른 비율과 조성을 통하여 노루궁뎅이버섯 균주를 접종한 후, 균사생장과 균사밀도, 자실체 생산량, 생물학적 효율을 조사 비교하였다. 참나무 톱밥 80%+미강 20%의 기질이 우수한 균사생장, 균사밀도, 자실체 생산량, 생물학적 효율을 보여 종균용 기질로써 적합하였다. 이러한 기질 조성의 적합성은 병재배법을 이용하는 농가에서 3개 노루궁뎅이버섯 균주를 사용하여 행한 실증실험에서 입증되었다. 그러나 봉지재배법을 이용한 농가 실증시험에서는 면자각 40%+참나무 톱밥 40% 기질에 옥수수 및 미강을 각각 10%씩 영양원으로 첨가한 기질에서 자실체 생산 및 생물학적 효율이 우수한 것으로 나타났다. This study was carried out to investigate the suitability of various agricultural by-products as basal substrates for the mycelial growth and fruiting body formation of Hericium erinaceum. For this aim, oak sawdust, cotton waste, sugarcane bagasse, Job's tears, rice hull, Chinese cabbage, and coconut waste were used as sole or mixed substrate(s). Corn waste and rice bran were used as nutrient supplements. The growth and density of mycelium, yield of fruiting body, and biological efficiency were compared among tested substrates colonized by Hericium erinaceum. The best measurement of mycelial growth and density, yield of fruiting body, and biological efficiency in a laboratory test was found in a spawn substrate composed with oak sawdust 80% and rice bran 20%. The suitability of this spawn substrate composition for Hericium fruiting body production was testified through practical tests in plastic bottles (850 ml) in a mushroom farm which had bottle cultivation facility. However, test in a mushroom farm which had plastic bag cultivation facility, best production of Hericium fruiting body (520 g per one bag) was observed in a spawn substrate composed of cotton waste 40%, saw dust 40%, corn waste 10%, and rice bran 10%.
