NaCl처리에 따른 느타리버섯균 및 푸른곰팡이균의 균사생장과 간척답 볏짚을 이용하여 느타리버섯의 재배 가능성 여부를 검토한 결과, salt 농도별 PDA배지에서의 버섯균의 균사생장은 대체적으로 0.2% 까지는 증가되며, 그 이상에서는 감소되는 경향이었다. 푸른곰팡이균은 0.5~1.0% 까지 거의 큰 차이가 없이 생장하였으며, 1.0~3.0%부터는 생장이 감소되기 시작하였고, 5.0% 에서는 현저히 감소되었다. 볏짚배지에 salt 농도별로 침수하여 버섯균의 균사생장은 한천배지와 같은 경향을 보였고, 병원균은 0.3%까지는 포자형성이 무처리구와 비슷하며, 0.5%에서는 포자형성이 감소되기 시작하여 5.0% 이상에서는 포자형성이 되지 않았다. salt 농도별로 처리된 볏짚배지에서는 처리농도가 증가함에 따라 NaO 함량은 높아졌으며, 살균전, 후 K2O는 감소되는 경향이었고, 수분함량은 NaCl 3.0% 까지는 비슷하였고 5.0%부터는 감소되었으며, pH는 뚜렷한 변화가 없었다. 볏짚배지 NaCl 농도별 처리에 따라 초발이소요일수는 차이가 없었으며, 버섯 수량은 무처리구와 비교하여 0.3% 처리구는 2,700g으로 수량이 비슷하였고 0.5% 이상에서는 수량이 감소된다. NaCl처리에 따른 침수용액 중의 EC는 볏짚 침수전보다 침수후에 높았으며, NaO 함량은 침수전, 후 모두 별다른 차이가 없었다. 볏짚종류에 따른 느타리버섯의 수량을 조사한 결과 간척답 볏짚이 일반답보다 약간 수량이 많았다.

This study was carried out to investigate effect of NaCl treatment on growth oyster mushroom and Trichoderma spp. on PDA and in rice straws. We also investigated the possibility of oyster mushroom cultivation using rice straw harvested from the reclaimed land having been drained sea water. Mycelial growth of oyster mushroom was increased by treatment of 0.2% NaCl but decreased by treatment of the higher concentration of NaCl. In the case of the mycelial growth on PDA of Trichoderma spp., no change was found in 0.5%∼1.0% NaCl, but decreased in the range of 1.0%∼3.0% NaCl and drastically decreased at 5.0% NaCl. In the rice straws treated with different concentration of NaCl solution, mycelial growth of oyster mushroom showed almost same result compare to PDA. The spore formation of Trichoderma mould was almost same in both 0% and 0.3% NaCl, decreased in 0.5% and was not found spores in the higher concentration of NaCl. As increasing salt concentration in the rice straws, the NaO contents were increased. The K2O contents were decreased before and after sterilization. The moisture content of rice straws showed no difference by treatment of 3.0% NaCl but decreased the moisture by treatment of 5.0% NaCl. No pH change was found in the rice straws treated with NaCl. Mushroom yield in the rice straw of reclaimed land was a little higher than that of normal paddy land straw. The duration of primordium formation was not affected by NaCl concentration in rice straws. The yield of fruiting body in 0.3% NaCl treatment was 2,700kg, which was almost same to non-treated plot, but decreased in 0.5% NaCl. EC value of soaking water after submerging rice straw was higher than before, but NaO content was not changed at both condition.
