Abstract

This study was carried out to know the effects of $N,\:P_2O_5,\:K_2O$ application and mulching materials on the yield and quality of Peusedanum japonicum. And conducted from 1990 to 1992 in the south region. The emergency rate by mulching materials was 80% on non-mulching, 74% on black P.E mulching, but 49% on the transparent P.E mulching. The yield of dried root on the transparent P.E mulching was increased 7% compared to non-mulching. The decreasing rate of yield was increased with the sequence of $N>P_2O_5>K_2O_5$. The significant negative correlation was obtained between the content of ash and nitrogen application, and the significant positive correation between the content of ash and potassium application. The contents of ash, acid insolubleash, and $C_2H_5\:OH$ OH extract were not affected by the treat-ment of mulching materials. When Peusedanum japonicum was cultivated in the south region for one year, optimum application of fertilizers was $N-P_2O_5-K_2O_5=21-13-10kg/10a.$

$1990{\sim}92$년간 남부지방 식방풍 재배시 3요소 시용랑및 피복처리가 수량 및 품질에 미치는 영향을 조사코자 시험한 결과를 요악하면 다음과 같다. 1. 3요소 시용량 시험 가. 3요소 각각 결제에 의한 수량 감수율은 질소>인산>칼리순으로 적었다. 나. 식방풍뿌리중 회분 함량과 질소 시비랑과는 부의 유의 상관관계가 있었고, 칼리 시용량과는 정의 유의적인 상관관계가 있었다. 다. 남부지방에서 식방풍 일년생 수확시 시비적량은 $N-P_2O_5-K_2O=21-13-10kg/10a$이었다. 2. 피복효과시험 가. 흑색비닐피복에서 출현율이 무피복 80%보다 6% 낮으나 수량이 7%정도 증수하므로 남부 지역에서는 흑색비닐피복재배가 좋을것으로 생각하며 투명비닐피복재배는 출현율이 낮아 수량이 25% 감수하였다. 나. 피복재료에 따른 식방풍의 품질조사결과 회분, 산불용성회분 및 엑기스 함량은 피복재료간 차이가 없었다.
