Background : A major medicinal plant, Angelica gigas Nakai, have using root parts and mainly cultivated the cool temperature region of high alpine as wild type in the northeast of China, Japan and Korea. The roots of grow it’s rapidly form August, and harvested from October to November. This study performed that the growth characteristics on soil mulching vegetation cultivation field of 300 m altitude of under Larix leptolepis (S. et Z.) Gordon in Bonghwa-gun, Gyeongsangbuk-do.
Methods and Results : After one-year seeding of the same size (7 - 8 ㎜) were transplanted in three types soil mulching of cultivation (plastic, straw and non-mulching) overground growth surveyed in three times (May to August), To confirm of soil condition compared the average. Soil condition of plot were observed to pH 5.56, OM 3.22%, T-N 017%, and growth increment were higher observed to that straw and non-mulching then plastic mulching of such as plant length 46.8 ㎝, stem diameter 5.9 ㎜, leaf length 24.4 ㎝ and width 28.9 ㎝, number of radical leaf 3.1. But from August, when the average temperature was high, the growth characteristics such as plant length, petiole Length, leaf length and width were reversed compared to those of plastic and non-mulching.
Conclusion : In case of cultivation of A. gigas in the environmental conditions of mountainous area, considering the growth from August to October when the roots growth bigger, It suggested that strew mulching is better than plastic and non-mulching, would be done through further research on underground growth characteristics of A. gigas according to harvesting time confirmed the relationship to the growth characteristics of A. gigas according to environmental conditions and soil mulching mountainous plantations.
