Abstract

After bottle culture of Pleurotus ostreatus, sawdust was taken out from the bottle and accumulated in the middle of March, and then composted. As the result, Y value was decreased rapidly 30 days after composting, and it was decreased slowly after 30 days. It is considered that 118 days is required for composting, however, it is possible to use for casing material after at least 48 days composting. The pH and total nitrogen content of sawdust based on composting period had tendency to increase as composting was processed. Total carbon and C/N rate had tendency to decrease as time went on. Based on the rate of 10, 30 and 50%, each sawdust was added to clay loam used as casing material for culturing A. bisporrus. Among various treatments, the mycelial growth of A. bisporus was more favorable in the treatment of 30% sawdust than in the single treatment of clay loam. Based on the date necessary for primodium formation of A. bisporus, the primodium formation in the treatment of 30% sawdust was reduced to about 5 days as compared with that of any other treatments When 30% sawdust was added to clay loam used as casing material for culturing A. bisporus, the yield of its fruiting body was increased to 28%.

애느타리 병재배후 탈병한 톱밥을 3월 중순 퇴적하여 부숙시킨 결과 퇴적기간에 따른 폐톱밥의 부숙정도는 퇴적 30일후에 가장 켰으며 부숙 소요일수는 최소 48일이었다. 퇴적 기간에 따른 폐톱밥의 pH 및 총 질소 함량은 부숙이 진전됨에 따라 증가하는 경향이었고 총 탄소 및 C/N율은 시간이 경과함에 따라 감소하는 경향이었다. 식양토에 부숙이 완료된 톱밥을 부피 비율로 10, 30, 50%씩 첨가하여 복토 재료로 사용한 결과 30% 첨가시 식양토 단용 처리보다 A. bisporus 균사 생장이 촉진되고 초발이 소요일수가 5일 빠르며, 수량에 있어서도 28% 증수되었다.
