Abstract
為了提高苦土石灰改良強酸性土壤缺鎂的效果，本試驗乃利用立體施肥機深施苦土石灰，期使深層土壤與苦土石灰充分混合。試驗地點在花蓮縣瑞穗鄉。試驗土壤為強酸性壤土。民國八十年在文旦果實採收後，進行六種試驗處理。六種試驗處理為(1).不施苦土石灰，(2).撒施苦土石灰，(3).溝施苦土石灰，(4).深施苦土石灰，(5).溝施苦土石灰並添加樹皮堆肥，以及(6).深施苦土石灰並添加樹皮堆肥。民國八十一年與八十二年，在八、九月間，分析土壤性質、葉片鎂含量以及文旦果實品質，並調查文旦果實產量。由分析調查結果得知，以立體施肥機深施苦土石灰，不論是否添加樹皮堆肥，皆可有效的提高土壤0~60cm深的鈣、鎂含量以及pH值，且深層施用苦土石灰之處理，其文旦果實產量最高，但各處理間文旦葉片鎂含量及文旦果實品質無明顯差異。
The main purpose of this experiment is to enhance the efficiency of Magnesium containing lime and the availability of Magnesium application in cooperating with a riller designed for deep fertilization. The experiment was conducted at Jui-sui, Hualine. The soil studied is strong acid loam. In 1991, after the harvest, six teratments, i.e. (1) control, (2)laying lime on the ground, (3) lime applied in the furrows, (4) deep fertilizer application by a driller, (5) furrow liming and amended with the bark compost, (6) deep fertilizer application with the bark compost.
