서 론 경북지역은 전국 과수 생산량의 60% 이상을 차지하고 있고 과수 종류도 다양하게 재배되고 있어 과원에 발생하 는 잡초 조사는 향후 고품질 과수 생산과 친환경 재배를 위한 기초 연구가 필요하다. 잡초 조사는 특정한 지역, 연 차별 일정한 조사시기로 실시되어야 잡초 종의 종수, 우점 도, 발생 양상 등의 변화를 파악하여 잡초 방제를 위한 기 초 자료로 활용이 가능하다(Kim et al., 2012). 잡초방제법 중 제초제 사용의 변화는 농업생태계 내 잡초종의 다양성, 발생량 및 우점 잡초종 변화의 주된 원인이며(Kim and Shin, 2007), 제초제 사용 중에서도 동일 제초제의 연용처 리가 농경지 발생잡초 군락 변화에 가장 직접적인 영향을 미친다(Kim et al., 2012). 최근에는 이상기온으로 인해 제 초제 사용과 더불어 외국으로부터 조사료 수입으로 인한 외래 잡초 유입 및 기후변화가 과원 발생 잡초 종의 변화 ABSTRACT.

The weeds classified by family and life cycle occurred in the five orchards were summarized as 36 family and 105 species in apple orchard, 34 family and 126 species in grape orchard, 34 family 126 species in peach orchard, 33 family 98 species in pear orchards, and 36 family 111 species in plum orchard. In addition to life cycle of weeds, most orchards except for pear orchard were dominant to biennial weeds. The most dominant importance value was observed in pear orchards as 6.57%. In winter's season, the weeds were summarized as 31 family and 89 species in apple orchard, 28 family and 71 species in grape orchard, 32 family 111 species in peach orchard, 27 family 68 species in pear orchards, and 33 family 83 species in plum orchard. In summer's season, the weeds were distributed as 31 family and 101 species in apple orchard, 27 family and 69 species in grape orchard, 29 family 91 species in peach orchard, 31 family 94 species in pear orchard, and 31 family 97 species in plum orchard. In winter season, the most dominant weeds in apple, grape, peach, pear, and plum orchard were Capsella bursa-pastoris, Laria media, Capsella bursa-pastoris, Capsella bursa-pastoris, and Erigeron canadensis, in turn. In summer season, the most dominant weeds in apple, grape, peach, pear, and plum orchard were Acalypha australis, Acalypha australis, Setaria viridis, Setaria viridis, and Setaria viridis, respectively.
