Abstract
1.氰氮化鈣施用量對上瓖分量比率小時，雖在四月間（溫度爲20℃~25℃）初期之分鮮仍甚迅速。
2.在盆栽試驗中，氰氮化鈣與純粹結晶之Cyanamide對水稻之毒害完全相同，而缺乏粘土之砂耕區受害更烈，因在此情形下，Cyanamide之分解困難也。
3.在臺北氣候環境下，若水田土型與本所相類似，施用氰氮化鈣以在插秧前六日爲適宜。

From the first report we Knew that the main poison effect on the application of calciam cyanamide in paddy soil was due to the decomposifion of cyanamide. The results of this report might be outlined as follows:
