Abstract

Investigation on weed flora in Angelica gigas upland fields was conducted to understand the current status of the weed flora and establish the control measures. Investigation was conducted twice, July and October in 2015. From this investigation, 105 species of 37 families including 27 exotics were identified and classified into 53 species of annuals, 24 species of biennials and 28 species of perennials. Dominance was the highest with Digitaria ciliaris, followed by Portulaca loeracea, Chenopodium album, Cyperus iria, Conyza canadensis, Galinsoga ciliata etc. in order. Chenopodium album was the highest in importance analysis and the followings were in order of Conyza canadensis, Galinsoga ciliata, Amaranthus lividus, Taraxacum offcinale etc. The yield of A. gigas was reduced 49.6% in no weeding plots comparing in weed managed plots.

충북 제천, 경북 봉화를 중심으로 당귀밭에 발생하는 잡초를 조사하여 당귀밭 문제잡초의 현황을 파악하고 잡초방제의 기초자료로 활용하기 위하여 2015년 5월과 6월에 실시하였다. 당귀밭에 발생하는 잡초는 37과 105초종으로 국화과 20종, 화본과 9종, 두과, 마디풀과, 사초과 각각 6종, 꿀풀과, 메꽃과 각각 5종 등의 순이었다. 이들 잡초를 생활형으로 구분하면, 일년생 53종, 월년생 24종, 다년생 28종이었다. 우점잡초로는 바랭이, 쇠비름, 흰명아주, 참방동사니, 망초, 털별꽃아재비 등이었다. 외래잡초는 27종으로 25.7%를 점유하고 있으며, 흰명아주, 망초, 털별꽃아재비, 개비름, 서양민들레, 개망초 순으로 우점도가 높았다. 잡초에 의해 당귀 수량은 49.6% 감소되었다.
