Studies on the Artificial Substrates with Rice Straw and the Spawning for Pleurotus florida in Korea

볏짚을 이용(利用)한 사철느타리버섯의 배지(培地) 제조(製造) 및 종균재식(種菌栽植)에 관한 연구(硏究)

This study was performed to examine the cultivation of Pleurotus florida that forms pinhead between 5 and $25^{\circ}C$, on rice straw substrates in Korea. The highest yield of P. florida sporophores was obtained from the fermented rice straw substrates added 5% rice bran to the rice straw by dry weight basis at the starting of fermentation. The pile turning of materials for uniform fermenting was made three times when the temperature of the pile reached $60^{\circ}C$ during out door composting. The $60^{\circ}C$ row steam was treated 6 hrs for pasterization of the substrates in the cultivating house. The quantity of spawn affected the mycelial growth and the yield of P. florida. The optimum amount of spawn was 10% to the rice straw by dry weight basis mixed with the substrates. P. florida produced normal sphorophores from September to middle of July of the following year.

1. 사철느타리버섯(Pleurotus florida)는 퇴적시(堆積時)에 미강(米糠)을 볏짚건물중(建物重)의 5%로 첨가(添加)하여 퇴비(堆肥)더미 정상부(頂上部)의 온도(溫度)가 $60^{\circ}C$일 때 3회퇴적(回堆積)한 발효(醱酵)볏짚부지(部地)에서 가장 높은 자실체(子實體) 수확(收穫)을 얻을 수 있었다. 2. 사철느타리버섯의 종균재식(種菌栽植)재직량(栽直量)을 볏짚건물중(建物重)의 10%로, 부지(部地)와 혼합재식(混合栽植)하였을 때 자실체(子實體) 수량(收量)이 가장 높았다. 3. 한국(韓國)에서 사철느타리버섯의 재배기간(栽培期間)은 9월(月)부터 익년(翌年) 7월중순(月中旬)까지였다.
