Abstract

Surveys of weed species in paddy fields were conducted to identify weed occurrence on July 2013. Total 237 sites of paddy fields in 9 City/Gun, Jeonnam Provinces in Korea were investigated. From the survey, 45 weed species in 18 families were identified and classified to 33 annuals and 15 perennials. Based on the occurrence ratio, the most weed species belonged to Poaceae (9 species) and 8 and 4 weed species belonged to Cyperaceae and Scrophulariaceae, respectively. These 21 weed species in the most four families accounted for 46% of total weed occurrence. The most dominant weed species in Korean paddy fields were Echinochloa spp. (18.5%), followed by Monochoria vaginalis (12.3%), Lemna perpusilla (8.2), Eleocharis kuroguwai (5.2%) and Scirpus juncoides (5.2%). The most dominant weed species in machine transplanting paddy fields were Echinochloa spp. (14%), followed by Monochoria vaginalis (12%) and in water seeded rice paddy fields were Echinochloa spp. (25%), followed by Monochoria vaginalis (11%). This information could be useful for estimation of future weed occurrence, weed population dynamics and establishment of weed control methods in paddy fields.

본 연구는 전남지역 논에서 벼 재배양식별 잡초 발생 현황을 파악하기 위하여 2013년 7월에 9개 시 군의 237지점에서 잡초분포조사를 수행하였다. 조사결과 전체 논에는 일년생잡초가 33종, 다년생잡초 15종을 포함한 18과 45종의 잡초가 발생하는 것으로 확인되었다. 발생한 잡초의 과별 구성을 보면 화본과 9종, 사초과 8종, 현삼과 4종 순으로 상위 3개 과가 포함하는 21종이 전체의 45.5%를 차지하였다. 조사된 잡초는 피 18.5%, 물달개비 12.3%, 개구리밥 8.2%, 올방개 5.2%, 올챙이고랭이 5.2% 순으로 우점하였다. 이번 연구결과를 이용하여 앞으로 논 잡초의 발생양상을 예측하며 잡초군락의 변화를 파악함으로써 효과적인 잡초 관리방안을 마련할 수 있을 것으로 판단된다.
