Abstract

In an effort to make it possible to cultivate Coptis japonica in Korea, the environmental and ecological conditions allowing the wild growth and distribution of Coptis sp. in Japan were investigated. The environmental conditions of the culture yard and the culture methods of C. japonica were also investigated. From these studies, it was concluded that the cultivation of C. japonica requires a well-drained sandy soil, $pH\;4.5{\sim}5.5$, which is facing North or Northwest. The area suitable for the cultivation of C. japonica should have rainfall of $1,000{\sim}1,500mm$ per year, be covered with snow for $30{\sim}60$ days in the winter, and be blocked $40{\sim}70%$, of the sun shine. These findings suggest that in korea the cultivation of C. japonica may be possible in the areas ranging from Sock-cho to Kang-neung, Mt. Odae, Mt. Taebaek and Mt. Sobaek where is chill and much moisturous in summer.
