Abstract

We analyzed the relationship between the main chemical properties (pH, total nitrogen content, total carbon content, and CN ratio) of sterilized medium and mushroom yields in 1 kg bag culture of Pleurotus ostreatus. The mushroom yields appeared to be highly correlated with the pH, total nitrogen content, and CN ratio, and were the highest under a total nitrogen content of 2.0-2.2% and a the CN ratio of 20-22.5. However, of the three parameters, total nitrogen content showed the highest correlation with the mushroom yield. The coefficient of determination(r2) between the total nitrogen content and the sum of the yield was 0.931, while that of the pH and CN ratio was relatively low. The nitrogen content of the medium was the most important factor in determining the yield of oyster mushrooms.

느타리 1 kg 봉지재배를 통해 살균배지의 주요 화학성과 2주기까지의 버섯 수량간 관계를 분석한 결과, 버섯수확량은 pH, 총질소 함량, CN율과 2차 함수식에서 매우 높은 상관을 보였다. pH는 4.9~5.0의 범위에서, 총 질소량은 2.0~2.2%에서, CN율은 20~22.5에서 가장 높은 수량성을 보였다. 1주기 버섯은 pH, 총질소량 및 CN율과 높은 상관을 보였고 2주기 버섯은 CN율 외에는 상관이 나타나지 않았다. 그러나 수량합계가 1주기 수량보다 3종의 화학성과의 관계에서 모두 더 높은 상관이 나타났다. 그리하여 본 연구에서 배지의 pH, 총질소 함량 및 CN율은 전 수확기간에 걸쳐서 버섯수량에 큰 영향을 미친다는 결론을 얻을 수 있었다.
