Abstract

This study was conducted to investigate the weed occurrence and distribution on the orchard fields (apple, pear, peach, grape) at 387 sites in Chungbuk province of Korea from May to September in 2015. From the result of this survey, 200 weed species in 47 families were identified and classified to 82 annuals, 40 biennials and 78 perennials. Based on the occurrence ratio, the most dominant weed species in Chungbuk province orchard fields were higher in order of Digitaria ciliaris (4.12%), Echinochloa crus-galli (3.60%), Stellaria aquatica (3.45%), Artemisia princeps (3.07%) and Chenopodium album (3.06%). The composition of major occurred weed families, Compositae, Poaceae, Leguminosae and Cyperaceae were 21, 9, 6 and 6%, respectively. Coefficient of similarity between a various orchards based on the degree of dominance were ranged from 68.7-91.8%. The most important weed species at apple, peach, grape was Digitaria ciliaris while these for pear was Poa annua. Fifty-one exotic weed species were also 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 orchard fields in Chungbuk province of Korea.

본 연구는 2015년 5월부터 9월까지 충북지역 11개 시 군의 387지점에서 과수원의 잡초 발생 현황을 조사하기 위하여 수행되었다. 충북지역의 과원 발생 잡초를 조사한 결과, 총 47과 200종이 발생되었다. 생활사별로는 각각 일년생이 82종, 월년생이 40종, 다년생이 78종 발생되었고, 일년생 잡초와 다년생 잡초의 발생 비율이 비슷하였다. 과별로는 국화과가 41종, 벼과 18종, 콩과 12종, 사초과 11종, 십자화과 10종, 현삼과 9종, 석죽과, 마디풀과 각각 8종 순이었다. 충북지역에서 우점잡초는 바랭이 4.13%, 피 3.60%, 쇠별꽃 3.46%, 쑥 3.07%, 흰명아주 3.07%의 순으로 발생되었고, 상위 20종의 우점도는 전체 잡초종의 50% 이상을 차지하였다. 전체 과원별 발생 잡초의 유사성 계수는 평균 84.9%로 사과와 복숭아가 91% 이상이었고, 시설 포도 78.7%, 노지 포도 81.3%, 배 83.1%로 비슷한 경향이었다.
