主要作物施肥適量試驗 九、香蕉施肥適量試驗

Abstract

本試驗係於民國四十九年及五十年分別在水裡抗及林邊兩地舉行二年之試驗成績結果如下: (l）由於每次試驗結果均表示極顯著之F-值，吾人可知三要素對香蕉的肥效極為可靠。 (2）每次試驗均表示平行增加三要素量時，其肥效均比單獨增加某一種要素時為高。可知香蕉施肥必須考慮三要素之平衡。 (3) 就以單要素之肥效觀之，磷肥肥效聶低，氮、鉀之肥效較高，水裡坑氮肥肥效大於鉀肥，林邊則鉀肥大於氮肥。 1. N. P and K have significant effects on the crop yield of banana according to this experriment. 2. Increasing N. P and K id propartion gave more increament in crop yield than increasing single element alone. This fact implies balanced N. P and K are important in banana fertilization. 3. Phosphorus is the least effective of the three elements. N and K are very impor-tant. In Shwei-li-keng, N was more important than K. but in Lin-pen, K was more important than K.
