Abstract
Major cation uptake by the rice plant and its leachates in submerged condition were studied at 3 different levels of potassium and nitrogen application with three texture soils (Clay loam, Loam, Sandy loam) by pot experiment. The results are as follows. 1. Potassium uptake and grain yields of rice plant were increased and calcium and magnesium uptake of rice plant were decreased by application of potassium. 2. The potassium application caused to increase Ca, Mg, K and
토성(土性)이 상이(相異)한 3개토양(個土壤)에서 질소시용량(窒素施用量)을 달리하여 벼의 생육(生育)이 각각(各各) 다른 조건에서 가리시용(加里施用)이 주요(主要) 양(陽)이온의 흡수(吸收)와 용탈(溶脫)에 미치는 영향(影響)을 찾기 위한 pot시험(試驗)에서 다음과 같은 결과(結果)를 얻었다. 1. 가리시용(加里施用)으로 가리(加里)의 흡수(吸收)는 증가(增加)되고 석회(石灰)와 고토(苦土)의 흡수(吸收)는 감소(減少)되었으며 정조수량(正租收量)은 증가(增加)되었다. 2. 가리시용(加里施用)은
