Abstract

This study was carried out to investigate effect of $CaCO_3$ treatment on cultivation of oyster mushroom for suppression of green mold disease and for promotion of mycelial growth to stabilize mushroom production in field and laboratory experiment. Treatment of $CaCO_3$ in PDA media promoted mycelial growth of mushroom and suppressed that of green mold. Addition of $CaCO_3$ in rice straw substrate increased mushroom mycelial growth compared with control. In that case, growth of green mold increased up to treated 0.6% $CaCO_3$ but decreased in treatment beyond 0.8% $CaCO_3$. There were some differences on effect of $CaCO_3$ treatment according to green mold species. Trichoderma longibrachiatum was effected but T. virens was not effected by treated $CaCO_3$. Differences among mushroom strains by treated $CaCO_3$ were not shown. It is confirmed that treatment of $CaCO_3$ can promote mushroom mycelial growth but it's not clear in the field. In the result of field test, treatment of $CaCO_3$ in rice straw substrates tended to increase yield and decrease incidence of disease compared with non-treatment. These results suggest that $CaCO_3$ treatment on cultivation of oyster mushroom can be applied to take preventive steps against of green mold disease.

느타리버섯재배에서 심각한 피해를 주고 있는 푸른곰팡이병을 억제하고 버섯균사의 생장을 촉진하여 버섯의 안정생산을 도모하기 위한 탄산칼슘의 처리효과를 실내 및 실외시험을 실시한 결과. PDA배지에서의 $CaCO_3$의 처리는 버섯균의 균사생장을 촉진하고, 병원균은 억제되었으며, 볏짚배지상의 $CaCO_3$의 처리에서는 버섯균은 무처리에 비하여 균사생장이 증가되었으며, 병원균 대체적으로 0.6%의 처리까지는 증가되나 0.8%처리부터는 감소되는 경향을 나타냈다. 컬럼 내의 볏짚배지에서의 Trichoderma longibrachiatum의 접종구에서는 $CaCO_3$의 처리효과가 있었으나 T. virens의 접종구에서는 $CaCO_3$의 효과가 없었다. $CaCO_3$의 처리에 따른 느타리버섯 품종간의 균사생장의 차이는 없었다. $CaCO_3$는 처리에 따라 느타리버섯의 균사생장은 촉진하고 푸른곰팡이병원균과 붉은빵곰팡이균에 대해 약간의 억제 능력은 인정되었다. 포장시험 결과 수량성은 무처리구에 비하여 높으며, 발병율은 낮은 경향이나 절대적인 방제효과는 없었다.
