Abstract

This study was carried out to investigate the cultivated soil properties, the growth and yield of Ostericum koreanum Kit. in the Bonghwa area. The results were as follows: In Bonghwa area, soil texture of upland soil were mostly sandy loam and loam. Sloped areas of $7\sim15%$ were plentiful than the other slopes, that of next was $15\sim30%$ slope. Sandy loam and loam soil were mostly 'well' in the drainage class, but loamy coarse sand and loamy sand soil were 'excessively well' drainage class. In the 'moderately well' drainage class, yield of Ostericum koreanum was 289kg/10a, and that of 'poorly' drainage class was low. The yield of loam soil texture was 284kg/10a. Soil organic matter, Potassium and EC were lower in 'poorly' drainage, but the other constituents were not definite tendency by different drainage classes.

강활 주재배지인 봉화지역 밭토양의 토양 특성을 조사하고 강활재배지 토양의 특성을 분석하여 토양환경과 적정 이화학성을 구명하기 위하여 강활의 생육상황과 수량을 조사한 결과는 다음과 같다. 1. 봉화지역 밭토양의 토성은 사양토와 양토가 대부분이었고 경사는 $7\sim15%$가 가장 많았으며 다음이 $15\sim30%$이었다. 2. 토양 배수등급별 토성 분포에 있어서는 사양토와 양토는 배수 양호가 많았으나 양토는 불량등급도 있었다. 양질조사토나 양질사토는 매우 양호 등급이었다. 3. 강활 수량은 양토와 배수등급 약간양호에서 289kg/10a으로 가장 많았는데 식양토와 배수불량등급에서 수량이 가장 적었다. 4. 강활 재배지의 토양유기물, 칼리함량, EC는 배수등급이 불량할수록 적어졌으며 그 외 함량은 배수등급간에 일정한 경향이 없었다.
