본 연구는 경상남북도 총 5개 지역 친환경 및 관행 밭 농경지에서 발생하는 잡초의 분포현황을 조사하기 위하여 수행하였다. 작물은 고구마, 옥수수, 콩, 고추, 호박으로 각 작물별 친환경 및 관행농업 재배지 총 10개 지역을 선정하여 조사하였다. 조사지역에서 전체 출현한 식물종은 28과, 76속, 97종, 7변종으로 총 104 분류군으로 조사되었다. 친환경 밭에서는 26과, 56속,72종, 3아종, 2변종으로 총 77분류군, 관행 밭에서는 22과, 58속,65종, 2아종, 2변종, 69분류군으로 분석되었다. 잡초의 우점 순위는 친환경농업에서는 바랭이가 가장 우점하는 것으로 조사되었고, 강아지풀, 환삼덩굴, 쑥, 돌피순이며, 관행농업에서도 바랭이가 가장 우점하였고 흰명아주, 돌피, 쑥, 쇠비름 순이다. 외래잡초는 전체 15과, 35종이출현하였으며 친환경농업 25종, 관행농업 23종으로 조사되었다. 작물과 잡초의 발생과는 상관관계가 있으면 친환경과관행의 잡초발생 차이는 나타나지 않았다.
This study was conducted to investigate the distribution of weeds occurring in environment- friendly and conventional fields in five regions of Gyeongsang-do. The crops were sweet potato, corn, soybean, pepper, and pumpkin. A total of 10 sites were selected for each crop, including environment-friendly cultivation and conventional cultivation sites. The total number of plant species that appeared in the survey area was 28 families, 76 genera, 97 species, and 7 varieties, totaling 104 taxa. In environment-friendly fields, 26 families, 56 genera, 72 species, 3 subspecies, and 2 varieties were surveyed, totaling 77 taxa. In conventional fields, 22 families, 58 genera, 65 species, 2 subspecies, and 2 varieties were surveyed, totaling 69 taxa. The dominance rank of weeds was that Digitaria ciliaris was the most dominant in environment-friendly agriculture, followed by Setaria viridis, Humulus scandens, Artemisia indica and Echinochloa crus-galli . In conventional agriculture, Digitaria ciliaris was also the most dominant, followed by Chenopodium album, Echinochloa crus-galli, Artemisia indica and Portulaca oleracea . A total of 15 families and 35 species of exotic weeds appeared, with 25 species in environment-friendly agriculture and 23 species in conventional agriculture. There was a correlation between the occurrence of crops and weeds, but there was no difference in weed occurrence between environment-friendly and conventional agriculture.
