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 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 %. 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.

2 72 이채영 박재성 이희두 김은정 홍의연 홍성택 우선희 al., 1995), 특히하절기에는잡초의종류가많고, 바이오매스가높기때문에적기에제초를하지않으면작물생산량에막대한피해를준다. 특히과수원에서는수관하부에발생하는잡초를집중적으로방제하고있고, 고랑에발생하는것은초생재배, 제초제살포, 기계제초등으로주로관리한다. 우리나라에서잡초는총 433종으로분류하고있으며, 국화과, 화본과, 마디풀과, 사초과, 콩과에속하는잡초가 209 종으로전체잡초의 48.2% 를차지하고있고, 십자화과, 장미과, 꿀풀과, 현삼과, 메꽃과를포함한 10개과에속하는잡초를모두합하면 280종으로전체의 64.7% 를차지한다 (RDA, 2013). 사과와배등의과수원에서잡초방제방법에따른제초효과를비교한결과, 잡초를연간 3회방제할경우잡초방제율은부직포피복은 %, 초생재배는 %, 기계제초는 %, 제초제 (gluphosinate ammonium) 처리는 % 로같은잡초방제방법이더라도과원별방제율의차이가있었다 (Jang et al., 2013, 2015; Lee et al., 2013, 2015b). 동일한방법으로과실수량을비교한결과, 사과원의수체당수량은무방제 13.3 kg, 부직포피복 20.4 kg (53.4%), 초생재배 24.1 kg (81.2%), 기계제초 25.3 kg (90.2%), 제초제 (gluphosinate ammonium) 3회살포 27.2 kg (104.5%) 이었고, 포도원의수체당수량은무방제 7.03 kg, 부직포피복 kg (51.8%), 초생재배 9.26 kg (31.7%), 기계제초 9.53 kg (35.6%), 제초제 (gluphosinate ammonium) 3회살포 kg (78.8%) 으로각각증수되었다 (Lee et al., 2013; Jang et al., 2015). 우리나라농경지에서발생하는잡초의조사는 1971년부터시작하였으나주로논과밭에집중되었고, 일부과수원에서발생하는잡초의우점초종을조사한연구결과는있었지만전국적으로정밀하게조사를시작한것은 2003년부터이다. 우리나라과수원에서발생한잡초는전국적으로총 51과 322종이확인되었고, 충청지역에서는 161지점에서조사한결과 44과 229종이발생되었다. 경기 강원에서 41 과 209종, 전라도 21과 146종, 경상도 43과 184종으로지역별로발생초종과우점도가달랐다 (Park et al., 2005a, 2005b). 충남지역의배와복숭아과원에서발생한잡초는 5월에는쑥, 메꽃, 다닥냉이와망초, 6-8월에는바랭이가우점하였고, 6개광역시 도사과주산지과원에서잡초조사를한결과, 충북지역에서는총 35종이발생하여망초, 여뀌, 뚝새풀, 벼룩이자리와꽃마리순으로우점되었다 (Pyon and Lee, 1982; Jung et al., 1997). 한국방제학회에서보고한과거의충북지역은 년에비해 년에는연평균평균기온이 정도증가하였고, 연평균최고기온은 0.7 o C-1.0 o C 상승되어, 지난 40년동안연평균변화율은 0.37 o C/10년-0.22 o C/10년에달하였다고보고하였으며 (Kim et al., 2011), 우리나라에서기상관측을시작한 1912년부터 2010년까지평균기온이 1.8 o C 상승되었고, 온실가스가현재추세로배출될경우 (RCP 8.5), 21세기후반한반도평균기온은 4.6 o C, 강수는 0.5 mm day 1 증가될것으로전망된다 (Ahn et al., 2014). 따라서이러한기후변화로인하여잡초의생활환경이변하고있고, 외국과의잦은교역과왕래로아열대또는열대잡초등외래잡초의유입이확산되어국내에서월동이가능하게될경우토착화되어생태계를교란하고, 작물재배에영향을줄가능성이크다. 잡초의초종과생활상은지역과영농형태에따라다르기때문에각지역별로잡초의발생현황을파악하고, 잡초의효율적인관리를위해농경지에서발생하는잡초를주기적으로조사하여자료를제공하는것은중요한일이다. 이에충북지역과수원에서발생하는잡초분포현황을알아보기위하여 11개시 군을대상으로발생된잡초의분포양상을정밀하게조사하여효과적인잡초방제를위한기초자료를확보하기위하여본연구를수행하였다. 재료및방법 충북지역의과수원에서발생하는잡초를조사하기위하여 2015년도 5월부터 9월까지도내 11개시 군을대상으로과수별주산단지위주로주요 4개작목 ( 사과, 배, 복숭아, 포도 ) 과원에서수행하였다. 조사대상선정은각작목별주산지역위주로, 행정구역구분에따라각시 군의읍 면 동에서무방제또는방제가불량한재배포장을임의로선정하였다. 사과과원은충주시, 제천시, 괴산군등지역에서 124개지점, 배과원은청주시, 충주시, 음성군등 87개지점, 복숭아과원은충주시, 음성군, 영동군등 94개지점, 포도과원은영동군, 옥천군등 82개지점등총 387개지점에서발생잡초의초종, 빈도및분포를조사하였다. 조사지역의중복을방지하고정확성을기하기위하여 GPS기 (GPS850, ASCEN) 를이용하여위도와경도를기록하였다 (Fig. 1). 발생잡초의초종은포장전체의분포현황을달관조사하였고, Braun-Blanquet (1964) 에의한 7등급 (5, 4, 3, 2, 1, +, r) 을적용하였으며, 이때각등급별조사기준은 5: %; 4: 50-75%; 3: 25-50%; 2: 10-25%; 1: <10%; +: 극히낮은피도로약간의개체수출현 ; r: 극히드물게최소피도로출현의기준으로초종별피도를조사하였다. 잡초의우점순위를알아보기위하여조사결과를토대로중요치 (IV) 분석을실시하였다 (Curtis and McIntosh, 1950).

Ratio of occurred weeds in the orchard fields based on their families in Chungbuk province in 각일년생이 82종 40%, 월년생이 40종 21%, 다년생이 78 종 39% 로발생되었다 (Fig. 2). 전년도밭작물재배지에서발생한잡초는 42과 188종으로, 일년생이 96종 51%, 월년생이 40종 21%, 다년생이 52종 28% 로분포되었다 (Lee et al., 2015a). 본조사결과에서다년생잡초의발생이많았는데이는밭에서는매년경운을비롯한농경지정리등잡초제거노력을하였기때문인것으로판단되었다. 2003년도중부지역사과, 배, 복숭아, 포도과원의발생잡초를조사한결과 43과 242종이발생되었고, 일년생 111종, 월년생 54종, 다년생 77종을차지하였다. 전국적으로는일년생 154종, 월년생 83종, 다년생 85종이발생되었는데 (Park et al., 2005a), 본연구결과와비교하여잡초종의수와다년생잡초발생비율에서차이가있었다. 잡초의과별로는각각국화과가 41종 21%, 벼과 18종 9%, 콩과 12종 6%, 사초과 11종 6%, 십자화과 10종 5%, 현삼과 9종 5%, 석죽과 8종 4%, 마디풀과 8종 4% 로 9개분류군이전체의 60% 를차지하였다 (Fig. 3). 충북지역사과과원에서발생한잡초는바랭이 4.28%, 쇠별꽃 3.58%, 피 3.55%, 서양민들레 3.03%, 흰명아주 3.00%, 배과원에서는새포아풀 5.04%, 쑥 4.55%, 쇠별꽃 4.02%,

Kim et al. (1982) 은과수원에발생하는잡초중바랭이가가장우점하는잡초이며, 밭에서발생하는대부분의잡초가과수원에서도마찬가지로발생한다고하였고, 이런결과는 Woo and Pyon (1988) 과 Hwang et al. (2004) 의연구에서도같은경향이었다. 망초와개망초는복숭아와포도과원에서발생이많았고, 이두잡초는환경적응성이뛰어나점차발생이증가되고있고, 동일한제초제의반복사용은제초제저항성잡초를출현시키기때문에 (Pyon et al., 2001), 앞으로도지속적인관리가필요할것으로판단되었다. 2003년조사에서중부지방과원에서발생한잡초중마디풀과의개여뀌의중요도가 4.03% 로높았으나 (Park et al., 2005b) 본조사에서는 0.76% 로낮아차이가있었고, 봄여뀌가 2.48% 로높은수준이었다. 외래잡초는 17과 51종이발생되어 26% 를차지하였다. 이중국화과가 17종으로가장많이발생되었고, 벼과, 현삼과가각각 4종, 십자화과, 아욱과, 콩과, 명아주과가각각 3종의순으로발생되었다 (Table 1). 2001년국내발생외래잡초는총 37과 315종, 1980년이후들어온것이 135종으로전체의 43% 정도였다. 2003년에충청지역에서조사한외래잡초는총 16과 38종이었으며, 충북지역은전작지에서 13 과 26종, 과수원에서 9과 13종이발생되었다고보고하였다
