Abstract

This study was conducted to investigate the possibility of biochar as an alternative medium to peatmoss using for Aster spathulifolius. We cultivated A. spathulifolius in four potting media with different mixing rates (v/v) of peatmoss (P) and biochar (B) as follows: B0+P3, B1+P2, B2+P1, and B3+P0 with vermiculite 3 + perlite 3. Also, we analyzed the chemical properties of media and the plant growth characteristics. The results were as follows: In case of media's chemical condition, B0+P3 and B1+P2 treatments showed higher tendency (p < 0.05). Plant height on B0+P3 and B1+P2 treatments was much higher than that on other treatments (p < 0.05). Root length on B1+P2 treatment was higher than on B0+P3 treatment (p < 0.05). B0+P3 and B1+P2 treatments showed higher number of leaves and dry biomass than other treatments. Therefore, our results support that Biochar : Peatmoss : Vermiculite : Perlite (1/3 : 2/3 : 1 : 1, v/v) could be a more economical potting medium for A. spathulifolius than peatmoss : vermiculite : perlite (1 : 1 : 1, v/v).

본 연구에서는 보다 효율적인 도시녹화 및 정원식물 생산을 위해 도시녹화 및 정원에 이용되는 주요 초본류 가운데 하나인 해국 유묘에 대해 피트모스 대체재로 바이오차의 가능성을 살펴보고자 바이오차 처리 수준에 따른 해국 유묘의 생육차이를 조사하였다. 연구결과 바이오차를 혼합한 배양토 처리에 따른 해국 유묘의 생장은 피트모스, 버미큘라이트, 펄라이트(1:1:1, v/v), 바이오차, 피트모스, 버미큘라이트, 펄라이트(1:2:3:3, v/v) 처리구에서 우수한 경향을 보였다. 따라서 해국 재배 시 피트모스, 버미큘라이트, 펄라이트(1:1:1, v/v)의 인공용토에서 피트모스를 대체할 만한 생장 효과를 나타낸 처리 비율은 바이오차, 피트모스, 버미큘라이트, 펄라이트(1/3:2/3:1:1, v/v) 처리구로, 사용된 바이오차의 유형, 함께 사용된 상토의 재료, 혼합 비율 등이 영향을 주었을 것으로 사료된다.
