Abstract

An attempt was made to establish the suitability classes of lands for the cultivation of ginseng(Panax ginseng C. A. Meyer). For this study, the relationships between various soil characteristics and ginseng yields were investigated on altogether 450 ginseng fields (150 sites in paddy and 300 sites in upland), across Kangwon, Kyunggi, Chungbug, Chungnam, Jonbug and Kyungbug Provinces, where ginseng is widely cultivated. In the paddy fields, most influential properties of soil on the ginseng yields was found to be the drainage class. Texture of surface soil and available soil depths affected the ginseng yields to some extents. However, the topography, slope, and the gravel content were found not to affect the ginseng yields. In the uplands, the texture of surface soil was most influential and the topography, slope, and occurrence depth of hard-pan were least influential on the performance of the crop. Making use of multiple regression, by SAS, the contribution of soil morphological and physical properties such as, topography, surface soil texture, drainage class, slope, available soil depth, gravel content, and appearance depth of hard-pan, for the suitability of land for ginseng cultivation was analyzed. Based on the results of above analysis, adding up all of the suitability indices, land suitability classes for ginseng cultivation were proposed. On top of this, taking the weather conditions into consideration, suitability of land for ginseng cultivation was established in paddy field and in uplands. As an example, maps showing the distribution of suitable land for ginseng cultivation were drawn, adopting the land suitability classes obtained through current study, soil map, climate map, and GIS information, for Eumsung County, Chungbug Province. Making use of the information on the land suitability for ginseng cultivation obtained from current study, the suitability of lands currently under cultivation of ginseng was investigated. The results indicate that 74.0% of them in paddy field and 88.3% in upland are "highly suitable" and "suitable".

논토양에서 토양의 형태적 및 물리적 특성이 인삼 수량에 미치는 영향을 보면 배수인자의 영향이 가장 컸고, 다음으로 표토의 토성과 유효토심의 영향이 컸다. 반면에 지형, 경사, 석력함량 등이 인삼수량에 미치는 영향은 미미하였다. 밭토양에서는 토양의 형태 및 물리적 특성 중 표토의 토성이 인삼수량에 미치는 영향이 가장 컸으며, 다음으로 유효토심, 석력함량, 배수 순으로 영향이 컸으나 지형, 경사, 경반층 출현깊이 등은 영향이 작았다. 토양의 형태 및 물리적 특성 중 인삼수량에 미치는 영향이 큰 지형, 표토의 토성, 배수등급, 경사, 유효토심, 석력함량 및 경반층 출현 깊이를 재배 적지 기준인자로 선정하였다. 다중회귀 확장기법을 이용하여 논과 밭토양에서 각각의 재배 적지 기준 인자가 인삼 수량에 미치는 기여도를 산출하였다. 인삼 재배 적지 기준 인자가 수량에 미치는 기여도와 적지 기준 인자별 수량지수를 이용하여 재배 적지 기준 인자별로 점수를 부여하고, 적지 기준 인자별 점수를 합산하여 최종 점수에 따라 최적지, 적지, 가능지, 저위생산지로 구분하였다. 최종적으로 토양특성과 기상조건을 중첩하여 논과 밭토양에서의 인삼 재배 적지 기준을 각각 설정하였다. 인삼 재배 적지 기준을 기반으로 하고, 토양도, 기후도 및 지리정보 시스템을 이용하여 주요 인삼 재배단지인 충청북도 음성군에 대하여 인삼 재배 적지 분포도를 작성하였다. 그 결과 필지별 인삼 재배 적지에 대한 정보를 인터넷을 통하여 경작자에게 실시간으로 제공할 수 있는 기반을 조성하였다. 인삼 재배지 조사지역에 대하여 인삼 적지 분포를 분석한 결과 최적지와 적지의 합계가 논토양에서 74.0%, 밭토양에서 88.3.%로 높아 인삼 경작자들이 비교적 적지에 인삼을 재배하고 있음을 확인할 수 있었다.
