초록

몇 수종을 대상으로 한 용기 양묘에서 폐암면 혼합 배지 이용 시 폐암면과 다른 배지의 혼합 비율에 따른 생육 특성을 조사하였다. 폐암면 혼합 비율에 따른 소나무의 생육 특성에서 생체중, 건물중 및 수고는 50% 와 70% 혼합배지에서 기장 좋았지만 원줄기 직경은 차이를 나타내지 않았다. 비자나무에서 생체중과 수고는 70% 혼합배지에서 가장 많이 증가하였고 원줄기 직경과 신초수는 50% 와 70% 혼합배지에서 많이 증가하였다. 상수리나무에서 생체중, 수고 및 원줄기 직경은 50%와 70% 혼합배 지에서 좋았고, 건물중은 혼합배지와 대조구간 차이를 나타났으나 혼합 비율간에는 차이를 나타내지 않았다. 잎의 엽록소 함량도 70% 혼합배지에서 높게 나타났으며 이에 광합성도 가장 활발하였다. 들메나무에서 생체 중은 70% 혼합배지에서 월등히 많이 증가하였지만, 수고와 원줄기 직경은 폐암면 혼합배지와 대조구 간 차이만 나타나고 혼합 비율간에는 차이를 나타내지 않았다. 잎의 엽록소 함량은 처리 간 차이를 나타내지 않았지만 혼합 배지에서 다소 높은 경향을 나타내었지만, 광합성은 70% 혼합배지에서 아주 활발하였다.

Growth characteristics according to mixture ratio of used-rockwool in pot nursery, in Pinus densiflora, Torreya nucifera, Quercus acutissina and Fraxinus mandshurica nursery, was investigated. The used-rockwool on mixture ratio between used-rockwool and control (peatmoss: pearlite=1:1, v/v) were 0%, 30%, 50% and 70%. Flesh weight, dry weight and height of tree, in Pinus densiflora nursery, increased much more in 50% and 70% media but trunk diameter of tree had no difference according to mixture ratio. In Torreya nucifera nursery, flesh weight and height of tree in 70% medium and trunk diameter and numbers of shoot of tree in 50% and 70% media increased. Flesh weight, height and trunk diameter of tree, and chlorophyll (SPAD) and photosynthesis rate, in Quercus acutissina nursery, increased much more in 50% and 70% media, but dry weight of tree had only difference between non-mixed and mixed with rockwool. In Fraxinus mandshurica nursery, flesh weight and photosynthesis rate of tree increased much more in 70% medium, height, trunk diameter and total chlorophyll of tree had difference according to non-mixed and mixed with rockwool or had no only difference according to mixture ratio, respectively.
