간척지에서 수도 (水稻) 및 기타작물의 내염성에 (耐鹽性) 관한 연구 - 13. 간척지에서 수도의 (水稻) 무기양분 흡수와 쌀 성분에 관하여 = Study on the Salt Tolerance of Rice and Other Crops in Reclaimed Soil Areas - 13. On the Absorption of the Mineral Elements of Rice and the Components of Rice Grains in Reclaimed Saline Soils.

다국어 초록 (Multilingual Abstract)

In order to observe the absorption pattern of mineral elements and the nutritional components of brown rice grown in reclaimed saline areas in Korea, the four commercial varieties of rice were culturad at the average salt concentration of 6.05 mmhos/㎝, 25℃, (0.3%) in saline soils and non-saline silty loam soils. In the saline areas the absorption of Na and Si was relatively high while the absorption of P, K and Ca, was relatively low. N was absorbed actively before the emergence of the rice grains but showed relative decrease thereafter. There was no difference in Mg content. Though brown rice in the saline areas contained sugar abundantly with small contents of protein, fat and crude fiber. There was little difference in total carbollydrate and ash contents.
