Abstract

This study was investigated in order to occurrence of weed flora in orchard (apple, grape, peach, pear etc.) fields and to the establishment of weed control basic data in these weeds. And this study was survey on 2015. As a result of the study on orchard weeds, there were total of 492 weeds including 63 families. Among all the weeds, 159 species were annual, 97 species were winter annual and 236 were perennial. Each fruit tree patterns of occurrence weeds, 306 species 50 families in apple orchard, 304 species 50 families in pear orchard, 286 species 50 families in grape orchard, and 288 species 48 families in peach orchard. Dominance was the highest with Digitaria ciliaris followed by Artemisia princeps, Stellaria aquatica, Commelina communis, Acalypha australis etc. in order. And exotics weeds occurred 127 species. Trifolium repens was the highest in importance analysis and the followings were in order of Conyza canadensis, Chenopodium album, Taraxacum offcinale, Rumex crispus etc. Changes in weed vegetation in orchard during 30 years, did not very many changed. In 1990, D. ciliaris, Persicaria hydropiper, Portulaca loeracea were dominant. In 2003, D. ciliaris was the most abundant species, followed by A. australis, A. princeps species. And in 2015, also D. ciliaris was the most dominant, followed by A. princeps, S. aquatica.

사과, 배, 복숭아, 포도 등을 재배하는 과수원에 발생하는 잡초를 조사하여 과수원 문제잡초의 현황을 파악하고 잡초방제의 기초자료로 활용하기 위하여 2015년에 전국을 11개 권역으로 나누어 실시하였다. 과수원에 발생하는 잡초는 63과 492종으로 국화과 86종, 화본과 63종, 두과 29종, 사초과 23종, 마디풀과 22종 등의 순이었다. 이들 잡초를 생활형으로 구분하면, 일년생 159종, 동계 일년생 97종, 다년생 236종이었다. 과수원별 발생잡초를 보면, 사과밭에는 50과 306종, 배밭에는 50과 304종, 포도밭에는 50과 286종, 복숭아밭에는 48과 288종이 발생되었다. 우점잡초로는 바랭이, 쑥, 쇠별꽃, 닭의장풀, 깨풀 등이었다. 외래잡초는 127종으로 전체의 25.8%이었고, 토끼풀, 망초, 흰명아주, 서양민들레, 소리쟁이 순으로 발생이 많았다. 30년간의 잡초군락 변화를 보면, 1990년에는 바랭이, 여뀌, 쇠비름 등이 우점하였으나, 2003년에는 바랭이, 깨풀, 쑥 등으로 변하였다. 2015년에는 바랭이, 쑥, 쇠별꽃 등으로 크게 변하지는 않았다.
