느타리버섯의 볏짚배지(培地) 발효방법(醱酵方法)에 관한 연구(硏究)

Studies on the Fermentation of Rice Straw Substrates for Cultivation of Pleurotus ostreatus

느타리버섯의 안전다수확(安全多收穫) 재배(栽培)를 위(爲)해 볏짚다발 배지(培地)는 야외(野外)에서 발효(醱酵)시키고 볏짚퇴비배지(堆肥培地)는 터널에서 살균(殺菌) 및 발효(醱酵)를 실시(實施)한 결과(結果) 1. 볏짚다발 배지(培地)는 야외(野外) 발효기간(醱酵期間)이 증가(增加)될수록 균사생장(菌絲生長)이 양호(良好)하였고 균사활착소요일수(菌絲活着所要日數)도 단축(短縮)되었다. 2. 볏짚다발 배지(培地)의 발효기간별(醱酵期間別) 느타리버섯 자실체(子實體) 수량(收量)은 야외(野外)에서 6일간발효(日間醱酵)(3회(回)뒤집기)한구(區)에서 $50.5kg/3.3m^2$로 가장 높았으며 관행방법(慣行方法)보다 24%증수(增收)되었다. 3. 느타리버섯 재배용(栽培用) 볏짚퇴비(堆肥)는 터널내(內)에서 4일간발효(日間醱酵)한 배지(培地)에서 균사생장(菌絲生長)과 초발용(初發茸) 소요일수(所要日數)가 빨랐으며 수량(收量)도 $67.6kg/3.3m^2$로 대조구(對照區)보다 17%가 증수(增收)되었다. 4. 느타리버섯 퇴비배지(堆肥培地)는 터널을 이용(利用)하여 살균(殺菌)과 발효(醱酵)가 가능(可能)하였으며 관행방법(慣行方法)보다 생산비(生産費)가 22. 3% 절감(節減)되었다.

To improve cultivation technique for the stable and high yield, the outdoor fermentation of rice straw bundles, and pasteurization and fermentation of rice straw compost in tunnel were carried out. 1) Mycelial growth of P. ostreatus was becoming rapid and dense according to prolongation of fermentation periods outdoor rice straw bundles, but days untill fully mycelial growth after spawning was short. 2) As the fermentation period of rice straw bundles was 6 days (three times turning), yield of P. ostreatus was the highest as $50.5kg/3.3m^2 and increased 24% of yield than those of conventional method. 3) When it was fermented rice straw compost in tunnel for 4 days, mycelial growth of P. ostreatus was rapid and dense, and also days untill budding after spawning, was shorter, yield $67.6kg/3.3m^2$, resulted in increasing 17% of yield than those of conventional method. 4) On being sterilization and fermentation of the rice straw compost in tunnel, the production cost was decreased 22.3% in compared with conventional method.
