Abstract

本研究係於溫室進行，將多量磷肥(500 ppm P)分四次同時施入本省十二種不同土壤中，每次施入後，及經浸水、風乾處里約一個月，以模擬田間情況。四次共歷時五個月。處理過的土壤(每土壤包括一不施磷之對照)再進行Neubauer法磷效應試驗，種植作物為小麥。目的為探討及比較原土壤中磷素與施肥磷素之聚積型態；化學測定法有效磷質與真正有效磷質間之關係，及施肥聚積磷素之回收率。 Phosphorus was incorporated into 12 different soils in 4 successive applications at 30 days interval in the greenhouse. After each addition, the soils were submerged for 10 days, than left until dry to simulate field conditions. A total of 500 ppm P was applied while a check treatment (no P was added) was included for each soil.
