Abstract

We surveyed the distribution of exotic weeds in the 350 upland crop fields of Gyeonggi-do. The exotic weeds were summarized as 78 taxa including 19 families, 52 genera, 74 species and 4 varieties. Among the total exotic weeds, the summer annuals were 48.7%, the winter annuals 28.2%, and the perennials 23.1%. Compositae was dominant family (32%), followed by Gramineae (8%), Polygonaceae (8%) and Malvaceae (7%). Dominant exotic weeds in northern Gyeonggi-do were Amaranthus lividus, Ambrosia trifida, Chenopodium album, Bidens frondosa and Erigeron Canadensis, and in southern Gyeonggi-do were Chenopodium album, Erigeron Canadensis, Erigeron annuus, Taraxacum officinale and Galinsoga ciliate. The most dominant exotic weeds in the Gyeonggi-do were Chenopodium album, followed by Amaranthus blitum, Erigeron canadensis. Canonical correspondence analysis for investigation of correlation between exotic weeds occurred in northern and southern Gyeonggi-do showed that the exotic weeds in northern Gyeonggi-do were more diverse then in southern Gyeonggi-do. This information could be useful for establishment of exotic weed control methods in Gyeonggi-do.

경기도의 밭 주변을 대상으로 350지점을 선정하여 조사를 진행하였다. 경기도의 밭에 발생하는 외래잡초 조사결과 19과 52속 74종 4변종, 총 78종류의 외래잡초가 조사되었고 하계 일년생 식물은 48.7%, 동계 일년생은 28.2%, 다년생은 23.1%가 출현하였다. 과별로 보면 국화과가 32%를 차지하여 가장 많은 비율로 출현하였고 벼과 8%, 마디풀과 8%, 아욱과 7%로 구성되었다. 경기북부에서의 외래잡초 우점종은 개비름, 단풍잎돼지풀, 흰명아주, 미국가막사리, 망초이고 경기남부에서는 흰명아주, 망초, 개망초, 서양민들레, 털별꽃아재비가 조사되었다. 경기도 전체에서는 흰명아주, 개비름, 망초가 가장 우점하는 것으로 파악되었다. 경기북부와 경기남부지역의 외래잡초의 상관관계를 살펴보기 위한 CCA 분석결과 경기북부가 경기남부지역보다 다양한 외래잡초가 넓게 확산되어 있는 것으로 분석되었다. 경기도에 발생하는 외래잡초의 발생정보는 밭의 지속적인 관리방안을 수립하는데 도움이 될 것이다.
