초록
1995년이후 부터 재배되어온 큰느타리버섯은 배양중 오염율 증가, 발이상태불량, 기형버섯의 발생, 수량 격감 등 이른바 연작장해로 불리어지는 재배상 문제점들에 대한 원인파악과 해결책이 요구되어, 발이상태 불량과 기형버섯 발생원인이 병원균과 발이 및 생육환경 관리방법에 있을 것으로 판단하고 병원균 종류 및 접종시기와 발이유기시 환기량에 따른 기형버섯 발생양상과 발이특징를 조사한 결과는 다음과 같다. 병원균 종류 및 접종시기별 배양율은 병원균 접종시기를 버섯종균접종과 동시에 접종할 때 44~63%로 낮았고, 병원균 종류별로는 Erwinia sp.+Peudomonas sp. 혼합 처리구에서 낮았다. 초발이소요일수는 발이유기시 환기를 충분히 시켰을 때(
We have researched on methods which can reduce fruit-body malformations of king oyster mushroom(Pleurotus eryngii). We collected many pathogens from diseased fruit-body or malformated fruit-body and identified with chemicobiological test and microscope. The factors of fruit-body malformations and increment of contamination during the pin-heading induction time were researched with ventilation amounts in growing room. When the pathogens having high pathogenicity were inoculated in spawn running bottle and at pin-heading induction time, symptom appeared or not appeared in according to air ventilation amounts in growing room. During the pin-heading induction time, humidity degree in growing room have kept of high level and air ventilation amounts were so little that fruit-body malformations ratio was high. But, even though pathogens were inoculated at the surface of bottle factitiously, if air ventilation amounts were enough, fruit-body malformation ratio was low.
