초록

이 연구는 시설양묘과정에서 요구되는 활엽수 수종별 적정 용기의 용적 및 생육밀도를 구명하고자 수행하였다. 용기 20혈(150본/$m^2$-400 mL), 24혈(200본/$m^2$-320 mL), 35혈(260본/$m^2$-240 mL)에서 거제수나무, 백합나무, 물푸레나무, 들메나무, 느티나무 및 참느릅나무 6 수종의 근원경, 간장, 물질생산량, 묘목품질지수 및 뿌리밀도를 조사 분석하였다. 용기에 따른 근원경, 간장, 물질생산량, 묘목품질지수 및 뿌리밀도는 6 수종 모두 용기 용적이 크고, 생육밀도가 낮은 20혈 용기에서 가장 높았다. 그러나 물푸레나무는 20혈과 24혈, 느티나무는 24혈과 35혈, 거제수나무는 세 용기 모두에서 유의적 차이는 없었다. 느티나무를 제외한 실험 대상 5 수종 모두 근원경, 간장, 물질생산량이 용기 용적과는 정의 상관관계, 생육밀도와는 부의 상관관계를 보였다. 이 결과를 바탕으로 양묘 단계에서 백합나무, 들메나무, 참느릅나무는 20혈, 물푸레나무는 20혈 또는 24혈, 느티나무는 24혈 또는 35혈, 거제수나무는 35혈의 용기가 적정 용기 크기로 판단된다. 수종별 적정 용기의 사용은 우량 묘목 생산이 가능하면서 경제적으로도 비용을 절감시킬 것으로 기대된다.

The purpose of this study was to evaluate the effects of container types on seedling growth of Betula costata, Liriodendron tulipifera, Fraxinus rhynchophylla, Fraxinus mandshurica, Zelkova serrata, and Ulmus parvifolia in the container nursery system. We used three container types [20 cavities (150 seedlings/$m^2$-400 mL), 24 cavities (200 seedlings/$m^2$-320 mL), and 35 cavities (260 seedlings/$m^2$-240 mL)] and measured root collar diameter (RCD), height, biomass, seedling quality index (SQI), and root density. The root collar diameter, height, biomass, SQI, and root density of seedlings were the highest at 20 cavities/tray in all six species because this container type has the largest volume and lowest seedling density. However, F. rhynchophylla growth at both 20 and 24 cavities/tray, Z. serrata growth at both 24 and 35 cavities/tray and B. costata growth at all sizes were not significantly different. As expected, container volume was positively correlated with RCD, height, and biomass of five species except for Z. serrata, but seedling density negatively did. Based on these results, 20 cavities/tray are optimal for L. tulipifera, F. mandshurica, and U. parvifolia, 20 or 24 cavities/tray for F. rhynchophylla, 24 or 35 cavities/tray for Z. serrata, and 35 cavities/tray for B. costata, respectively. Usage of optimal container will make us get good quality seedlings as well as reduction of production costs in the container nursery.
