구상나무 4년생 용기묘의 생육에 미치는 배양토의 영향

Abstract

The purpose of this study was to evaluate the effects of bed soil on growth characteristics of 4-year-old Abies koreana container seedlings, in order to establish a production system for A. koreana. The distribution and population of A. koreana in South Korea are decreasing due to the effects of climate change. In this study, container seedlings of A. koreana grown in bed soil A (Agricultural bed soil) and HA (Horticultural + Agricultural bed soil) were found to have good height, root diameter, and crown width, and the H (Height)/D (Diameter) ratio of the container seedlings was found to be in the range of 2.8 to 3.6. Total dry weight was also highest in bed soil A and HA. T (Top)/R (Root) ratio was in the range of 2.18 to 3.75. Seedling quality index and total biomass were significantly higher in bed soils A and HA, which were treated with the lowest water content of any of the bed soils. In bed soils HA and A, the root development of the container seedlings such as the total length, total surface area, and total project area were found to be excellent. The growth of the above and root, and dry weight by organs of A. koreana container seedlings indicated that the best bed soils were A and HA, which had relatively low moisture content.
