초록
우리나라에서 재배되고 있는 약용작물인 당귀, 황기, 길경, 작약, 양유, 천궁, 시호 등의 생약재와 약초재배지 토양 254점을 채취하여 재배지의 토성을 분류하고 토성별 토양 및 생약재중 중금속함량을 분석 검토하여 얻어진 내용을 요약하면 다음과 같다. 1. 약용작물 재배지의 토성별 분포비율은 사양토 46.1%, 양토 26.0%, 양질사토 19.3%, 미사질양토 8.6%이었고 중립질인 양질토양(사양토, 양토, 미사질양토)에서 염농도, 유기물, 치환성 Ca 및 Mg함량이 높았던 반면 조립질인 사질토양(양질사토)에서는 유효태
This survey was conducted to investigate the distribution of heavy metal contents in medicinal plants and soils. Plant and soil samples were collected at 254 sites(Angelica gigas : 81, Astragalus membranceus : 38, Platycodn glandiflorum : 36, Paeonia albilora : 34, Codonopsis lanoceolata : 32, Ligusticum chuanxiong : 17, Bupleurum falcatum : 16, respectively) over the country, Soil texture, pH values and heavy metal content of soils and medicinal plants were evaluated as major factors. Soil texture classification showed that sandy loam, loam, loamy sand and silt loam were 46.1%, 26.0%, 19.3% and 8.6% of the total, respectively. The contents of O.M, Ex.Ca. Ex.Mg and EC value were higher in loamy(sandy loam, loam and silt loam)soils than in sandy(loamy sand)soils, but available
