Abstract

This study was conducted in order to investigate the distribution pattern of weeds on upland crop field in northern Gyeonggi-do. The weeds were summarized as 201 taxa including 42 families, 129 genera, 178 species, 1 subspecies, 21 varieties and 1 form. One hundred and thirty one species were classified to annual plants, accounting for 65.1% and 70 species were classified to perennials, accounting for the rest of 34.9%. Compositae was dominant family (21%), followed by Gramineae (12%), Polygonaceae (7%) and Brassicaceae (5%). Among the weeds appearing in the fields of northern Gyeonggi-do, the invasive weeds were classified to 62 species in18 families. The most dominant weed species in the fields were Portulaca oleracea, followed by Echinochloa crus-galli, Amaranthus lividus. Detrended correspondence analysis for investigation of occurrence pattern of weeds by crops revealed the occurrence pattern of weed species in adlay field were different from those in other crop fields. This information could be useful for establishment of weed control methods in northern Gyeonggi-do.

경기북부 밭 경작지에서 발생하는 잡초의 분포현황을 파악하기 위하여 본 조사를 수행하였다. 조사결과 42과 129속 178종 1아종 21변종 1품종, 총 201분류군이 조사되었고 생활형은 전체 식물 중에 다년생은 70종으로 34.9%, 일년생은 131종으로 65.1%로 분석되었다. 이중 국화과가 21%로 가장 많이 출현하였고 다음은 벼과 12%와 마디풀과 7% 그리고 십자화과 5% 순으로 출현하였다. 밭에 출현한 잡초 중에서 외래잡초는 18과 62종이 분포하고 있는 것으로 조사되었다. 밭 잡초의 우점종을 판단하기 위한 중요치 분석에서는 쇠비름이 가장 높았으며 돌피, 개비름 순으로 조사되었다. 작물별로 잡초의 상관관계를 살펴보기 위한 DCA 분석결과 율무밭의 잡초종이 다른 밭의 잡초종과 차이가 있는 것으로 분석되었다. 이러한 발생정보는 경기북부 밭 잡초의 효율적인 관리방안을 수립하는데 기여할 것으로 판단되었다.
