Abstract

We surveyed the distribution pattern of weeds in onion, garlic, potato, and barley fields including 304 sites of Gyeongsangbuk-do. The weeds were summarized as 30 family and 125 species in onion crop field, 29 family and 101 species in garlic field, 30 family 88 species in potato field, finally 27 family and 108 species. Compositae was dominant family (26.4%, 33 species), followed by Polygonaceae (8.8%, 11 species), Cruciferae (8.8%, 11 species) in onion field. Compositae was also dominant family (24.8%, 25 species) in garlic field, it was 22.7% (20 species) in potato field, and it was also 24.1% (26 species) in barley field, respectively. Among these winter crops, major five families were occupied 61.1, 58.4, 58.0 and 57.5% in turn at barley, onion, potato and garlic fields. The PCA-covariance plot analysis for investigation of occurrence pattern of weeds by four winter crop fields revealed that the occurrence pattern of weed species in barley field was distinguished by Alopecurus aequalis var. amurensis, Stellaria alsine var. undulate and Stellaria aquatica.

본 연구는 2014년 4월부터 9월까지 경북지역 13개 시 군의 식량작물(양파, 보리, 마늘, 감자) 재배포장에 발생되는 잡초의 분포와 우점도를 알아보기 위하여 수행되었다. 양파밭은 30과 125종, 마늘밭은 29과 101종, 감자밭은 30과 88종, 보리밭은 27과 108종으로 조사되었다. 잡초종 수에 따른 주요 과(family)는 Table 2와 같다. 양파밭에서는 국화과(Compositae) 33종으로 전체 잡초종에서 26.4%, 마디풀과(Polygonaceae)와 십자화과(Cruciferae) 11종으로 8.8%를 차지하였다. 동계작물 재배지의 주요 5개 과에 대한 초종수와 점유율은 양파밭 73종 58.4%, 마늘밭 58종 57.5%, 감자밭 51종 58.0% 및 보리밭 66종 61.1%로 양파밭, 보리밭, 마늘밭, 감자밭 순으로 초종이 많았고 초종별 점유율은 보리밭에서 61.1%로 가장 높았다. PCA (Principal Community Analysis) 분석에서 보리밭의 벼룩나물, 뚝새풀 및 쇠별꽃은 마늘, 양파 및 감자밭에서 발생되는 초종과 뚜렷한 구별성을 보였다.
