Abstract
本試驗之主要結果茲摘錄如下：
(1)單獨施用微量元素對幼苗插秧前後生育及穀實收量均有顯著優良效果，其適量範圍爲：Mn 20~50p. p. m. Cu 10-15p. p. m., B1 p. p. m., Zn1-5p. P. m.。
(2)穀實收量之效果，茲以百分率比較共結果，按標準爲100時，Mn 20P. P. m.施用區爲105, 50p. p. m.區爲101, Cu 10 p. p. m.區爲112, 15 p. p. m.區爲121， B1 P. P. m.區爲147, Zn 1p. p. m.區爲101, 5p. p. m.區爲107。
(3)苗床土壤反應就上述施用量範圍內，影響極小。
This paper is intended to acertain the effectibility of some minor elements which were separately applied in the soil on the growth of young rice seedlings. There are to sections of this experiment being concerned: (1) the effectibility on the young seedlings after application of the minor elements; (2) the effectibility on the paddy Lice after transplantation from the nursery.
