Abstract

This survey was conducted to identify weed occurrence and to investigate weed management methods in the apple orchard fields in Chungnam province including Daejeon and Sejong from April to June and from September to October, 2015. In this survey, 64 weed species in 27 families including 39 annuals and 25 perennials were identified. Based on the importance values, the most dominant weed species in the first survey was Poa annua (6.51), followed by Veronica didyma (5.36), Plantago asiatica (5.36). In the second survey, Stellaria media (5.73), Digitaria ciliaris (5.36), and Rumex crispus (5.18) were dominant. When the 64 weed species were classified by family, the most abundant weed species belong to Compositae (12 species), followed by Poaceae (7 species), Polygonaceae (6 species), and Cruciferae (6 species). These 31 weed species in the most occurred four families accounted for 48% of total weed occurrence. Based on the questionnaire survey in which weed management methods in the apple orchard were asked, applied mowing + herbicide, mowing + tillage, and mowing + sod-culture was methods commonly conducted in apple orchard fields.

본 연구는 2015년 4월부터 6월(1차 조사), 9월부터 10월까지(2차 조사) 2차례에 걸쳐 대전광역시와 세종특별자치시를 포함한 충청남도지역의 사과원에 발생하는 잡초분포현황과 잡초관리방법을 확인하기 위하여 수행되었다. 조사결과 충남지역 사과원에 27과 64종의 잡초가 발생하는 것을 확인하였다. 이 중 일년생잡초는 39종이였으며 다년생 잡초는 25종이였다. 1차 조사에서는 새포아풀(6.51), 개불알풀(5.36), 질경이(5.36)순으로 우점하였으며, 2차 조사에서는 별꽃(5.73), 바랭이(5.36), 소리쟁이(5.18)순으로 우점 하였다. 발생잡초를 과별로 분류하면 국화과가 12종으로 가장 많이 발생하였고 화본과는 7종, 마디풀과는 6종 발생하였다. 잡초관리 방법에 대한 설문조사 결과 충남지역 사과원의 55%가 예초와 제초제나 경운 또는 초생재배를 함께 사용하는 것으로 조사되었다. 예초를 통해 잡초관리를 할 경우 25종의 잡초가 발생하여 방제효과가 낮은 것으로 조사되었다. 충남지역 사과원에서 선호하는 제초제는 glufosinate-ammonium으로 연간 2-3회 사용하는 것으로 조사되었다.
