Keywords: | 土壤;天然;矽酸;施肥 | Issue Date: | Jun-1983 | Publisher: | 中華農學會 | Journal Issue: | 新122 | Start page/Pages: | 46-63 | Source: | 中華農學會報 | Abstract: | 利用稻田長期矽酸爐渣效果試驗10處各三種爐渣處理區(不施區,六作累計施用 9t/ha 後停施三作區及六作累計施用 18t/ha 後停施三作區)的土壤計30種,作為材料,採用Neubauer 稻苗消耗吸收法,探查土壤化學分析所得「有效態矽酸」單位含量的真正有效程度,在連年施用矽酸爐渣而殘積矽酸後的土壤及在祇含天矽酸的土壤,究竟有無不同,以及土壤中其它肥力因子的影響如何,以供修改矽酸施肥需要性診斷標準的參考。 An experiment was conducted to clarify (1) whether the actual availability to rice per unit of the chemically tested "available" silica differs between the soils which have accumulated silica from the previous application of siliceous slag and those soils that contain the native soil silica only, and (2) whether soil factors other than the "available" silica have an influence on its actual availability, with a view to improving the diagnostic criteria for predicting the needs for silica fertilization. |
