氮磷化成肥料對水稻之效應試驗

Abstract

為明瞭使用氮磷化成肥料栽培水稱時之適當使用方法在民國46~48年間選擇臺北、桃園、埔心、員林等地舉辦田間試驗，每試驗地均同樣設置12處理4重覆隨機排列法之田間設計，由本次試驗結果顯示單使用氮磷化成肥料對于水稻生產效果較使用硫酸錏為差，若使用硫酸錏為基肥氣磷化成肥料當追肥使用時之水稻產量較高於全部使用氮磷化成肥料。各試驗處理區谷實收量指數總平均如下。 Field experiments were conducted in Taipei, Taoyeun, Pushin and Yenlin in order to find the most effective method of application for the nitrophosphate. The experimental design has 12 treatment with 4 replication arranged in randomized black. It was found in these experimental results that nitrophosphate alone gave yield less than that of ammonium sulphate. When ammonium sulphate was used as base manure and nitrophate as top-dressing, the crop yield was also higher than that of using nitrophosphate alone.
