Abstract
This study was conducted to identify problematic weed species in grape orchard fields to establish basic information for suitable weed control. Surveys of weed species occurring in grape orchards were conducted in Chungnam province including Daejeon and Sejong of Korea from April to June and from September to October in 2015. From the surveys, 50 weed species belonging to 23 families (33 annuals and 17 perennials) were identified. In the first survey, the most dominant weed species by the importance values was Poa annua (7.07) followed by Echinochloa crus-galli (6.56), Digitaria ciliaris (6.43) and Capsella bursapastoris (5.63). In the second survey, Rorippa palustris (9.59), Eclipta alba (9.13), Digitaria ciliaris (7.68) and Poa annua (7.68) were dominant. Different weed species and dominance patterns were detected according to weed control methods in the grape orchards. Seven weed species belonging to six families were identified in the field in which herbicides were being used as a weed control method. However, most weed species (21 species belonging to 9 families) were occurred in the mowing + tillage fields. These surveys provide information about seasonal variations of weeds species occurred in grape orchards and impact of different weed control methods on the weed occurrence.
본 연구는 충남지역 포도원의 발생잡초를 확인하고 잡초관리기술개발의 기초자료로 활용하기 위하여 2015년 4월부터 6월, 9월부터 10월까지 2차례에 걸쳐 대전광역시와 세종특별자치시를 포함한 충청남도지역의 포도원에서 잡초분포조사를 수행하였다. 충남지역 포도원에서 발생하는 잡초는 일년생 33종, 다년생 17종을 포함하는 23과 50종의 발생을 확인하였다. 1차 조사에서는 새포아풀(7.07), 돌피(6.56), 바랭이(6.43), 냉이(5.63)가 우점하였고, 2차 조사에서는 속속이풀(9.59), 가는잎한련초(9.13), 바랭이(7.68), 새포아풀(7.68) 순으로 우점하였다. 잡초방제방법에 따른 잡초발생은 제초제만 처리한 경우 6과 7종으로 잡초종의 발생이 가장 적었으며, 예초와 경운을 이용한 경우 9과 21종으로 가장 많은 초종이 발생하는 것으로 나타났다.
