건묘육성(健苗育成)을 위(爲)하여 밀양(密陽)23호와 아끼바레 두 품종(品種)으로 묘대(苗垈)에서 용성인비(熔成燐肥)와 규산질(珪酸質) 비료시용(肥料施用)이 묘(苗)의 건물중(乾物重), 무기성분(無機成分), 함량(含量), 묘생육등(苗生育等)에 미치는 영향(影響)을 비교검토(比較檢討)한 결과(結果)는 다음과 같다. 1. 최대(最大) 건물중(乾物重)은 품종간(品種間) 비료반응(肥料反應)이 약간씩 달라 용성인비(熔成燐肥) 75~150kg/10a, 규산질비료(珪酸質肥料) 100~200kg/10a시용구(施用區)에서 얻었다. 2. 건묘(健苗)의 엽근비(葉根比)는 1이 적당하였으며 용성인비(熔成燐肥)에서는 75kg/10a, 규산질(珪酸質) 비료구(肥料區)에서는 200kg/10a수준(水準)이었다. 3. 용인(熔燐)75kg/10a수준(水準)의 식물분중 무기성분(無機成分)인 N
Fused phosphate and slag have used as a sources of phosphate and silicate fertilizers. In order to find out effects of these fertilizers on the growth of young rice plants in nursery, relationships between dry matter production and nutrient uptake at different fertilizer application rates were investigated for two rice varieties, Milyang 23 (a Indica-Japonica hybrid) and Akibare (a Japonica). The results were summarized as followers; 1. The maximum dry matter production was obtained at 75-150 kg/10a of fused phospate and 100-200 kg/10a of slag, respectively, however, a some variations between varieties were recognized. 2. The top/root ratio of varieties around 1.0 was proper for healty see dings and this ratio was reached at application of 75 kg/10a of fused phosphate and 200 kg/10a of slag. 3. The efficiency of applied silicate of rice seedlings was higher in fused phosphate than in slag. 4. The growth of seedling was severely retarded when soil pH was increased above 7 by the application of more than 225 kg/10a of fused phospahte and 400 kg/10a of slag.
