Abstract

本研究綜合檢討9處矽酸爐渣連用試驗經歷4½年(9作水稻)及1處矽酸爐渣、稻藁連用試驗經歷6年(12作水稻)之收量結果，並分析矽酸爐渣之連用對土壤化學性質之影響。試驗地點分布西部各縣、土壤均屬酸性。9處矽酸爐渣連用試驗之處理為(1)對照區(不失矽酸爐渣)，(2)矽酸爐渣每期作每公頃1.5公頃，(3)矽酸爐渣每期作每公頃3公噸，但自第7作(69年第2期作)起將(2)及(3)處理各分為二半，一半繼續施用矽酸爐渣(照原量)，另一半則停施以觀矽酸爐渣之殘效及續施效果。 Field experiments have been carried out island-wide at 9 paddy locations on acid soils for 4½ years (9 crops) using 3 treatments: (1)check, no siliceous slag applied, (2) siliceous slag applied at the rate of 1.5 t/ha/crop, and (3) siliceous slag applied at the rate of 3 t/ha/crop. Nitrogen, phosphate and potash were amply applied to all of the test plots following the stantard recommended method. A randomized block design with two replications was adopted as the experimental procedure.
