초록
본 연구는 ebb & flow 방식에서 기린초를 분화재배할 때 적당한 배지를 선발하기 위한 것으로서 분화용 양액 (Sonneveld액)을 관주한 후 생육과 양분흡수특성을 분석하였다. 피트모스와 펄라이트를 5:5 또는 7:3(v/v)으로 혼합한 배지는 코이어와 펄라이트를 동일한 비율로 혼합한 상토보다 가비중과 건물함량은 높았지만 수분함량은 낮았고 그 밖의 물리적 특성은 차이가 없었다. 피트모스 혼합 배지는 코이어 혼합 배지보다 pH는 낮고(5.4) EC는 높으며 (
Sedum kamtschaticum has been used as one of the native valuable plants for ornamental purpose. This experiment was conducted to find out the optimum media for pot cultured Sedum kamtschaticum using peatmoss and coir-based mixtures. Four mixtures such as peatmoss:perlite(5:5, v/v), peatmoss:perlite(7:3, v/v), coir:perlite(5:5, v/v), and coir:perlite(7:3, v/v) were used. Plants were irrigated with a Sonneveld solution in an ebb & flow system. The content of T-N, K, and Ca in the peatmoss-based media was higher than those of the coir-based media. The concentration of T-N, K, and Ca in the shoots of Sedum kamtschaticum increased when plants were cultured with peatmoss-based media. In the peatmoss-based media, plant growth, such as number of branches, leaf length and shoot fresh and dry weights, were significantly increased than those of plant grown in the coir-based media. As the results, the optimum media for pot cultured Sedum kamtschaticum in an ebb & flow system was considered to be the peatmoss-based mixtures.
