Abstract

Surveys of weed species on upland fields were conducted in Korea to investigate the occurrence of weed flora from April to May 2014 for winter crop fields and from July to August 2014 for summer crop fields. From the nation-wide survey, 375 weed species in 50 families were identified and classified to 162 annuals, 78 biennials and 135 perennials. Based on the occurrence ratio, the most weed species belonged to Compositae (73 species). 44 and 25 weed species belonged to Poaceae and Polygonaceae, respectively, and these 183 weed species in the most five families accounted for 49% of total weed occurrence. While 287 weed species in 45 families occurred in the winter crop fields, 339 weed species in 47 families occurred in summer crop fields. The most dominant weed species in Korean upland fields were Digitaria ciliaris, followed by Portulaca oleracea, Acalypha australis, Chenopodium album, Rorippa palustris etc. 129 weed species in 25 families were considered as exotic weeds. Based on the importance analysis, the highest value was C. album followed by Amaranthus lividus, Conyza canadensis etc. This information could be useful for estimation of future weed occurrence, weed population dynamics and establishment of weed control methods in upland fields of Korea.

우리나라 밭에 발생하는 잡초를 조사하여 각 작목별 문제잡초의 현황을 파악하고 잡초방제의 기초자료로 활용하기 위하여 2014년 4~5월 및 7~8월에 2회 실시하였다. 밭에 발생하는 잡초는 총 50과 375종으로 국화과 73종, 화본과 44종, 마디풀과 25종, 십자화과 21종, 콩과 20종 등의 순이었다. 이들 잡초를 생활형으로 구분하면, 일년생 162종, 월년생 78종, 다년생 135종이었다. 보리, 마늘, 양파 등 동계작물 재배지에는 45과 287종, 고추, 콩, 옥수수 등 하계작물 재배지에는 47과 339종이 발생되었다. 우점도별 상위 10초종은 바랭이, 쇠비름, 깨풀, 흰명아주, 속속이풀, 돌피, 한련초, 중대가리풀, 냉이, 참방동사니 순이었다. 외래잡초는 25과 129종으로 흰명아주, 개비름, 망초, 좀명아주, 미국가막사리, 털별꽃아재비 등이었다. 밭잡초 발생정보는 향후 잡초발생 예측, 잡초군락 변화 그리고 밭잡초 방제의 기초자료로 유용하게 사용될 수 있을 것이다.
