Abstract
A pot experiment of paddy rice was carried out primarily to find out the effect of potash in relation to the application of wollastonite on paddy rice. The result which showed increased paddy rice yield has been evaluated from the factors of yield, yield components, soil and plant analysis data at different stages of plant growth and the summary of review is described as follows : 1. Effect of potash is likely to be greater in the presence of wollastonite and a larger quantity of wollastonite application would require correspondingly larger quantities of potash. 2. Application of potash and wollastonite resulted increased paddy rice yield may be largely due to increased contents of potassium, calcium and silica in the soil and increased concentration of
수도(水稻)에 있어서 가리(加里)의 시용(施用)이 규회석(珪灰石)의 효과에 미치는 영향(影響)을 밝히기 위(爲)하여 Pot시험(試驗)을 실시(實施)하고 정조수량(精租收量)을 증가(增加)시킨 원인(原因)을 수량(收量) 및 수량구성요소(收量構成要素)와 수도(水稻)의 생육시기별(生育時期別) 토양(土壤) 및 식물체분석성적면(植物體分析成績面)에서 검토(檢討)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 가리(加里)의 효과는 규회석(珪灰石)이 시용(施用)되었을 때에 더 커지며 규회석(珪灰石)의 시용량(施用量)이 많을수록 가리(加里)의 요구량(要求量)도 많아진다. 2. 가리(加里)와 규회석(珪灰石)의 시용(施用)은 토양(土壤) 및 고중(藁中)의 가리(加里), 석회(石灰) 및 규산(珪酸)의 농도(濃度)를 증가(增加)시키며
