초록
낙동강(洛東江) 하류수계(下流水系)의 관개수질(灌漑水質)이 벼 생육(生育)에 미치는 영향(影響)을 알기 위하여 경남지방(慶南地方)의 주요(主要) 관개수원(灌漑水源)인 6개 양수장(揚水場)을 대상(對象)으로 각(各) 지점별 수질(水質), 토양(土壤) 및 벼의 근활력(根活力)을 조사(調査)한 결과(結果)를 요약(要約)하면 다음과 같다. (1) COD는 지류(支流)<본류(本流)<하류(下流)의 순(順)으로 낙동강(洛東江) 하류(下流)인 김해(金海)에서 오염도(汚染度)가 가장 높았다. (2) 수질(水質)의 화학성분(化學成分) 중(中) electric conductivity, SAR, Cl,
This study was performed to obtain some basic informations about the effects of irrigation water on the growth of rice plant. The water quality was surveyed at six pumping stations from the Nam river tributary to the downstream of Nakdong river, and sampling sites of soil and plant were five paddy fields near-by each station during rice growing periods in 1983. 1. Average value of COD was 5.1-7.1 ppm at 2 sites of the Nam river tributary, 11.4 ppm at 1 site of the midstream and 9.1-13.4 ppm at 3 sites of the downstream of Nakdong river. 2. The relationships between irrigation water and soil were
