Abstract

This study was conducted to investigate the weed occurrence and distribution on the upland crop fields (garlic, barley, potato, maize, red pepper, soybean and Chinese cabbage) at 795 sites in Chungbuk province of Korea from Apr. to Oct. in 2014. From the result of this survey, 188 weed species in 42 families were identified and classified to 96 annuals, 40 biennials and 52 perennials. Based on the occurrence ratio, the most dominant weed species in Chungbuk province upland crop fields were higher in the order of Portulaca oleracea (8.14%), Digitaria ciliaris (6.72%), Echinochloa crus-galli (6.55%), Rorippa palustris (6.00%) and Chenopodium album (5.89%). The composition of major occurred weed families, Compositae, Poaceae, Polygonaceae and Cruciferae were 19, 10, 7 and 6%, respectively. In the winter upland crop fields, the dominant weeds were in the order of Capsella bursa-pastoris (12.36%), Alopecurus aequalis (11.05%) and Stellaria alsine (8.42%). In the summer upland crop fields, the dominant weeds were in the order of Portulaca oleracea (8.58%), Digitaria ciliaris (7.18%) and Rorippa palustris (6.28%). Fiftythree exotic weed species were identified. The results of this study could be useful information for estimation of future weed occurrence, weed population dynamics and establishment of weed control methods on the upland crop fields in Chungbuk province of Korea.

본 연구는 2014년 4월부터 10월까지 충북지역 11개 시 군의 795지점에서 주요 밭작물 재배지의 잡초 발생 현황을 조사하기 위하여 수행되었다. 충북지역의 밭잡초 조사결과, 42과 188종이 발생하였고, 생활사별로는 각각 일년생이 96종, 월년생이 40종, 다년생이 52종이 발생하였고 대부분 일년생 잡초였다. 과별로는 국화과가 36종, 벼과 19종, 마디풀과 13종, 십자화과 12종, 사초과, 콩과 각각 11종 순이었다. 동계작물 재배지의 우점잡초는 냉이(12.36%), 뚝새풀(11.05%), 벼룩나물(8.42%), 광대나물(4.82%), 쇠별꽃(4.60%)의 순이었고, 하계작물 재배지의 우점잡초는 쇠비름(8.58%), 바랭이(7.18%), 속속이풀(6.28%), 흰명아주(6.22%), 중대가리풀(4.95%)의 순으로 발생되었다. 충북지역의 우점잡초는 쇠비름(8.14%), 바랭이(6.72%), 피(6.55%), 속속이풀(6.00%), 흰명아주(5.89%), 중대가리풀(4.64%), 깨풀(4.10%), 개비름(3.84%), 한련초(2.52%), 냉이(2.15%)의 순이었다. 쇠비름, 바랭이, 피 등 상위 10종의 우점도는 전체 잡초종의 50% 이상을 차지하였다. 10년 단위로 작물 재배지의 잡초분포를 조사하여 잡초군락의 변화를 파악함으로써 기초자료를 활용하여 체계적인 밭잡초 관리방안을 마련할 수 있을 것으로 판단되었다.
