Abstract

This study aims to establish the directions for the optimal nutrient contents determined by soil and leaf analyses. The study is to be used as a source for basic information in investigating the effects of nutritional environment on ginseng growth at the fields of Ansung region in Gyeonggi province. The physical property of soil porosity is closely related to ginseng growth, with more than 50% of good growth in the field. The optimal range of chemical properties in soil was analyzed as 0.20-0.28% T-N, 500-900 mg/kg Av.P$_2$O$_5$, and 2.3-3.5 cmol$^+$/kg Exch.Ca. The optimal range of inorganic nutrient contents in leaves was also analyzed. P value was less than 0.25%, and Mg was more than 0.22%. Other elements were not found clearly. The ratios of N/P, N/Mg, K/Mg, and Ca/P of leaves with good growth in the field showed 10<, 10-13, <14, 1<, respectively. In addition, the Ca:Mg:K ratio of the Exch.cation (cmol$^+$/kg) may be useful as an indicator in the assessment of plant growth in ginseng.

이 연구는 경기도 안성지역에서 우량 및 불량 인삼재배지를 대상으로 토양 및 잎을 분석하여 인삼의 생육에 적합한 양분함량의 수준을 구명하고자 수행하였다. 인삼생육과 밀접한 관계를 보이는 물리적 성질은 공극률이었으며, 우량포지에서 50%이상의 값을 보였다. 토양의 화학적 성질의 적정범위는 전질소 2.0-2.8 g/kg, 유효인산 500-900 mg/kg, 치환성 Ca 2.3-3.5 cmol$^+$/kg 이었다. 또한, 치환성 염기 성분비 (Exch. Ca:Mg:K)도 인삼생육에 영향을 미치는 것으로 나타났는데 그 값은 우량포지에서 6:2:1, 불량포지에서 4:2:1로 나타났다. 잎의 무기양분함량 적정범위는 P 0.25% 이상, Mg 0.22%이하였으며 그 외의 원소에 있어서는 뚜렷한 값을 나타내지 않았다. 우량포지에서 엽 중 N/P, N/Mg, K/Mg, Ca/P의 함량비는 각각 10 이상, 10-13, 14 이하, 1 이상의 값을 나타내었다.
