본 연구는 산마늘의 임간재배를 위한 기초 환경자료를 제공하고자 실시하였다. 울릉도 산마늘은 너도밤나무, 우산고로쇠나무, 섬잣나무, 솔송나무, 소나무, 곰솔, 섬피나무, 두메오리나무 군락에 자생하고 있으며, 입지환경은 평균 해발고도 563.4 m, 평균 경사는 27.8°이었다. 토성은 사토, 사질양토, 양질사토, 양토가 다양하게 나타났으며, 유기물층의 깊이는 평균 6 cm, 토양 pH는 5.40, 유효인산은 18.5 ppm, 양이온 치환용량은 18.6 cmolc/kg으로 나타났다. CCA분석에 의한 입지와 토양인자와의 상관관계를 보면 너도밤나무군락은 탄소, 질소, 모래함량, 양이온치환용량과 정의 상관관계를 나타내었다.
The purpose of this study was to provide basic data for the cultivation of Allium victorialis var. platyphyllum in the area covered with forest vegetation. The populations of A. victorialis var. platyphyllum in Ulleungdo were naturally growing in the communities of Fagus japonica var. multinervis, Acer okamotoanum, Pinus parviflora, Tsuga sieboldii, Pinus densiflora, Pinus thunbergii, Tilia amurensis, and Alnus maximowiczii. On average, the study area of A. victorialis var. platyphyllum population was located in the places of 563 m above sea level, and in the slope area of 27.8°. Soil texture of its inhabitation site mainly consisted of sandy soil, sandy loam, loamy sand, and loam. The depth of the organic layer was 6 cm on average, soil pH 5.4, available phosphate content 18.5 ppm, and cation exchange capacity 18.6 cmolc/kg. The correlation between the site factors and soil factors by CCA analysis showed that the community of beech tree indicated positive correlation with carbon, nitrogen, sand content, and cation exchange capacity.
