Abstract
The experiment was conducted in 1996 to investigate distribution, germination characteristics, and effective control of Abutilon theophrasti in corn fields. The regional distribution of A. theophrasti showed that it was higher in Gyenggi province than in Kangwon, Chungnam, or Chonllanambug provinces because of many dairy farms located in Gyenggi province where fresh corn was used as ensilage. The optimal temperature of the weed seed germination was around 15~
사료용(飼料用) 옥수수 포장에서 문제(問題)가 되고 있는 외래잡초(外來雜草)인 어저귀의 발생분포(發生分布), 종자발아(種子發芽) 특성(特性) 및 약제방제(藥劑防除) 시험(試驗)을 실시(實施)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 사료작물용(飼料作物用) 옥수수 재배면적(我培面積)이 넓은 경기(京幾), 강원(江原), 충남(忠南), 전남북(全南北) 등(等) 17개(個) 지역(地域)을 대상(對象)으로 어저귀의 분포(分布)를 조사(調査)한 결과(結果) 경기도(京幾道) 지역(地域)이 사료용(飼料用) 옥수수를 엔씨레지용(用)으로 이용(利用)함으로써 어저귀의 발생정도(發生程度) 및 발생량(發生量)이 강원(江原), 충남(忠南), 전남북지역(全南北地域)보다 높았다. 2. 어저귀 종자(種子)의 발아적온(發芽適溫)은 15~
