Abstract

In this study, we surveyed the distribution pattern and dominance of weeds occurred in four summer crop fields, hot pepper, soybean, maize, and Chinese cabbage in Gyeongbuk province. The weeds were summarized as 32 family and 132 species in hot pepper field, 31 family and 116 species in soybean field, 37 family 134 species in maize field, finally 35 family and 170 species in Chinese cabbage field. Among these weeds occurred in the four summer crop fields, the compositae was commonly dominant family, it occupied 17.4% in hot pepper field, 18.1% in soybean field, 11.9% in maize field, and 16.5% in Chinese cabbage field. The major five families including compositatae, graminae, polygonaceae, convolvulaceae and cruciferae were occupied 43.2% in hot pepper field, 47.4% in soybean field, 42.5% in maize field, and 43.5% in Chinese cabbage field, respectively. Furthermore, the most dominant weed in the hot pepper, soybean, maize, and Chinese cabbage fields was Portulaca oleracea, Digitaria ciliaris, and Rorippa palustris, respectively. This information could be useful for estimation of future weed occurrence, weed population dynamics and establishment of weed control methods in food crop fields of Gyeongbuk province.

본 연구는 2014년 4월부터 9월까지 경북지역 17개 시 군의 고추, 콩, 옥수수 및 배추 재배포장에 발생되는 잡초의 분포와 우점도를 알아보기 위하여 수행되었다. 조사결과, 고추밭 32과(family) 132종(국화과 23종, 벼과 10종, 메꽃과 8종), 콩밭 31과 116종(국화과 21종, 벼과 10종, 메꽃과 9종), 옥수수밭 37과 134종(국화과 16종, 벼과 12종, 메꽃과 11종), 배추밭 35과 170종(국화과 28종, 메꽃과 14종, 벼과 13종)이 출현하였다. 작물별 우점도는 고추밭 쇠비름 10.07, 콩밭 바랭이 9.63, 옥수수밭 바랭이 8.28, 배추밭 속 속이풀 8.35로 나타났다. PCA-covariance 분석을 통한 주요 잡초군락은 냉이로 대표되는 배추밭과 돌피로 대표되는 옥수수밭 그리고 공통적으로 왕바랭이, 쇠비름 및 깨풀로 대표되는 고추밭과 콩밭으로 구별되었다.
