摘要

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. The experimental results were briefly stated a follows:
(1) It is obviously significant that after a separately single application of different minor elements the young seedlings have grown much better than the check area either in the nursery bed or in the paddy field. Moreover, better yields could also be obtained rather than that of the untreated area. The avilable amounts of the minor elements applied in this experiment were Mn 20-50 p.p.m., Cu 10-50 p.p.m., B 1 p.p.m. Zn 1-5 p.p.m. respectively.
(2) Among the different treatments the results as compared with the untreated area (assume the index in the untreated area being 100%) were: 105% and 191% yields in the Mn of 20 p.p.m. and 50 p.p.m. respectively. At the same time, 112% and 121% of Cu with 10 p.p.m. and 15 p.p.m.; 147% of B with 1 p.p.m.; 101% and 107% of Zn with 1 p.p.m. and 5 p.p.m being obtained.
(3) The minor elements which have been app1ied as above amounts, were studied of very little reaction on the soil of the nursery bed. (From the Laboratory of Sails and Fertilizers, Taiwan University)
