Abstract

For 2 years $(1993{\sim}1994)$, study on development of cheap medium for Pleurotus ostreatus revealed that paper sludge contain more CaO and similar T-C, T-N, $P_2O_5$, MgO but less $K_2O$ than any other medium material in chemical property. Mixed treatment (rice straw + paper sludge 10, 30, 50%, cotton waste + paper sludge 10, 30, 50%, cotton waste + rice hull 20 + paper sludge 10, 30, 50, 70%) is similar or fast a little in mycelial growth and is similar or fast $1{\sim}2$ day in period of primordia formation than cotton waste medium, and in the yield to each medium type also increased but excepted in rice hull 20% + paper sludge 70%, especially mixed medium at 7:3 ratio of cotton waste and paper sludge is best treatment because it is increased to 21%. In economical analysis, mixed medium at 7:3 ratio of cotton waste and paper sludge is increased to 50% compared to cotton waste medium in relative income.

느타리버섯 재배에 있어서 배지재료로 제지부산물의 사용 가능성을 검토한 결과 배지재료별 화학특성은 제지부산물이 폐면, 볏짚, 왕겨보다 CaO는 많았고, T-C, T-N, $P_2O_5$, MgO는 비슷하였으며 $K_2O$는 현저히 적었다. 균사생장은 혼합처리가 폐면단용보다 생장이 다소 빠르거나 비슷한 경향이었다. 초발이소요일수는 폐면단용보다 혼합처리가 비슷하거나 $1{\sim}2$일 정도 빠른 경향이었다. 배지종류별 수량은 폐면단용에 비해 폐면 10+왕겨 20+제지부산물 70% 처리를 제외하고는 증수되었으며, 특히 계면+제지부산물 30% 혼합처리가 21% 증수되어 가장 우수하였다. 경제성분석결과 폐면단용보다 폐면+제지부산물 30% 혼합처리에서 소득지수가 50% 높게 나타났다.
