Abstract
This study was conducted to evaluate the effect of herbIcides on weed control, growth characteristics and yield in Angelica gigas NAKAI, after transplanting it to the field. All herbicids treated had no effect on the emergency period, bolting rate, and growth characteristics of A. gigos. Simazin wp, methabenzthiazuron wp were slightly harmful, but linuron wp pendimethalin ec, triflurain ec had no injury on the A. gigas, even with double dosage level. Under the treatment of pendimethalin ec, linulon wp, effect of weed control valuae at 55 days after transplanting was 89.6, and 88.3 respectively with 5 or 7 species of weeds appearing. Broadleaf weeds f?ere abundant than grasses, and the major weeds were C. albam, C. flexuos, D.sanguinalis, and E. arvense. Dry yield were increased somewhat more with herbicides than by hand weeding, even with double dosage level.
참당귀(當歸) 이시재배시(移植栽培時) 몇가지 제초제(除草劑) 처리(處理)가 잡초발생(雜草發生)과 당귀(當歸)의 생육(生育) 및 수량(收量)에 미치는 영향(影響)을 검토(檢討)코져 시험(試驗)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 제초제(除草劑) 처리(處理)가 출아기(出芽期)와 추대률(抽臺率) 및 생육상황(生育狀況)에 미치는 영향(影響)은 나타나지 않았다. 2. Simazin Wp 와 Methabenzthiazuron Wp 처리(處理)는 도장(圖場) 약해(藥害)가 경미하게 나타났으며, Linuron Wp, Pendimethain Ec, Triflurain Ec 는 배양처리구(倍量處理區)에서도 약해발생(藥害發生)이 없었다. 3. 잡초(雜草) 방제가(防除價)는 Pendimethalin Ec, Linuron Wp 처리(處理)에서 89.6, 88.3 이었으며, 발생초종(發生草種)도
