Abstract

Surveys of weed species in paddy fields were conducted in Korea to identify weed occurrence from June to September 2013. Total 3,434 sites of paddy fields in 155 City/Gun, eight Provinces were investigated. From the nation-wide survey, 90 weed species in 28 families were identified and classified to 52 annuals, 3 biennials and 35 perennials. Based on the occurrence ratio, the most weed species belonged to Poaceae (18 species). 17, 8 and 6 weed species belonged to Cyperaceae, Scrophulariaceae and Polygonaceae, respectively, and these 49 weed species in the most four families accounted for 54% of total weed occurrence. The most dominant weed species in Korean paddy fields were Echinochloa spp. (17.4%), followed by Monochoria vaginalis (12.4%), Eleocharis kuroguwai (7.8%), Bidens tripartite (9.27%), Scirpus juncoides (6.2%) and Sagittaria sagittifolia (6.1%). This information could be useful for estimation of future weed occurrence, weed population dynamics and establishment of weed control methods in paddy fields of Korea.

본 연구는 전국 논의 재배양식별 잡초 분포현황을 알아보기 위하여 2013년 6월부터 9월까지 도 농업기술원, 농업 대학 및 관련 연구소 등 11개 기관에서 전국 8도 155개 시 군의 3,434지점에서 잡초분포조사를 수행하였다. 조사결과 2013년 현재 우리나라 논에는 일년생잡초가 52종, 월년생잡초 3종, 다년생잡초 35종을 포함한 28과 90종의 잡초가 발생하는 것으로 확인되었다. 발생한 잡초의 과별구성을 보면 화본과 18종, 사초과 17종, 현삼과 8종 마디풀과 6종 순으로 상위 4개 과가 포함하는 49종이 전체의 54%를 차지하였다. 조사된 잡초는 피 17.4%, 물달개비 12.4%, 올방개 7.8%, 올챙이고랭이 6.2%, 벗풀 6.1% 순으로 우점하였다. 이번 연구결과를 이용하여 앞으로 전국 논잡초의 발생양상을 예측하며 잡초군락의 변화를 파악함으로써 체계적인 논잡초 관리방안을 마련할 수 있을 것으로 판단된다.
