초록

곰취밭에 발생하는 잡초발생 양상과 잡초로 인한 피해정도를 파악하여 곰취밭 잡초방제의 기초자료로 활용하기위하여 2013년 5월부터 10월까지 5회 조사하였다. 곰취밭에 발생하는 잡초는 37과 104종으로 일년생잡초가 55종,월년생잡초 25종 그리고 다년생잡초가 24종이었다. 이 중에서 외래잡초는 26종이 발생하였다. 우점도가 높은 잡초로는 명아주, 쇠별꽃, 돌피, 망초, 쑥 등이었으며, OrdinationPCA 분석한 결과, 고마리-미국가막사리 군락, 명아주 군락 그리고 냉이 군락으로 분석되었다. 잡초에 의한 곰취의 피해 정도를 곰취 뿌리 무게로 비교한 결과, 잡초관리구에 비교하여 잡초방임구가 56% 작아져서 이듬해 곰취생육에 영향을 줄 것으로 판단된다.

This study was conducted in order to utilize the basic data for weed control by surveying the occurrence of weedspecies and the degree of damages caused by those weeds occurred in cultivated Ligularia fischeri fields. Survey was carried outfive times, on May, June, July, August and October in 2013. The weed flora was composed of a total of 104 weeds, 37 families, ofwhich 55 species were annual, 25 species were biennial, and 24 were perennial plants. Twenty-six exotic species were included aswell. Dominance was the highest with Chenopodium album followed by Stellaria aquatica, Echiochloa crus-galli, Conyzacanadensis, and Artemisia princeps etc. in order. In the PCA plot analysis, weeds occurred in cultivated L. fischeri fields weredivided into three groups, Persicaria thunbergii-Bidens frondosa community, Chenopodium album community and Capsella bursapastoriscommunity. The degree of damages in cultivated L. fischeri fields was investigated by weighing roots of L. fischeri.
We found that 56% decreased root weight in no weeding plots comparing to that in weed management plots. We infer from thisresult that decreased roots will affect to the growing of L. fischeri in following year.
