Abstract
A pot experiment was conducted to investigate the dry matter weight of soybean plant, fertilization efficiency, and the changes of p uptake with different p application levels in cultivated and uncultivated soils controlling the soil moisture content to 2 levels. 1. The effect of irrigation was higher in cultivated soil than in uncultivated soil, and was higher in larger amount of p application than in small amount of p. 2. Efficiency of phosphate fertilization for soybean growth was higher in cultivated soil compared with uncultivated soil, and increased by irrigation to optimum soil moisture content for crop growth. 3. Adjustment of soil moisture content to optimum level for soybean growth increased the concentration of phosphate in plant and decreased the content of phosphate in soil. Therefore, it was obvious that soybean plant absorbed the high amount of p in the optimum soil moisture level and in large amount of p application.
밭 토양(土壤)의 수분함량(水分含量)을 다르게 조절(調節)하면서 대두(大豆)에 대한 인산(燐酸)의 시비반응(施肥反應), 시비효율(施肥效率) 및 시용인산(施用燐酸)의 흡수량(吸收量) 변화(變化)를 조사(調査)하기 위하여 숙전(熟田)과 개간전토양(開墾田土壤)을 공시(供試)한 pot시험결과(試驗結果)는 다음과 같다. 1. 관수(灌水)의 효과(效果)는 개간전토양(開墾田土壤)보다 숙전토양(熟田土壤)에서 높았으며 인산(燐酸)의 시용량(施用量)이 증가(增加)함에 따라 증대(增大)되었다. 2. 인산(燐酸)의 시용효율(施肥效率)은 개간전토양(開墾田土壤)에 비(比)하여 숙전토양(熟田土壤)에서, 토양(土壤)의 수분조건(水分條件)이 양호(良好)하도록 관수(灌水)된 조건(條件)에서 높았다. 3. 토양(土壤)의 수분조건(水分條件)이 양호(良好)하도록 관수(灌水)된 조건(條件)(
