摘要

由中部地區葡萄肥料試驗、適作地區調查及葡萄需肥診斷研究顯示，葡萄園土壤以中質地之坋質壤土較佳。葡萄園土壤肥力測定值適宜範圍，分別以酸鹼度pH 6.6~7.5，有機質含量2~3%，有效磷含量200~400公斤／公頃，交換性鉀200~400公斤／公頃，交換性鈣8,000~16,000公斤／公頃，交換性鎂高於1600公斤／公頃者葡萄質量均佳。三要素施用量對葡萄品種及質量均互有關係，施高量時產量較高，但糖度偏低，酸度提高。氮素用量範圍50~100公斤，磷酐及氧化鉀各為100~200公斤／公頃。

Following the studies of the vineyard fertilizer field test and the fertilizer requitement diagnosis in central Taiwan, it showed that the silt loam was the best vineyard soil. The proper soil fertility ranges of the vineyard that produce good grape are as follows: pH, 6.6-7.5; organic material content, 2.3%; avaiable P content, 200-400 kg/ha; exchangeable K, 200-400 kg/ha; exchangeable Ca, 8000-16000 kg/ha; and exchangeable Mg, over 16000 kg/ha. The dosage of N, P, K fertilizers is related to the varieties and the quality and yield of grapes, a higher yield is harvested when the fertilizer used is higher, but the sugar content tends to decrease and the acidity increase. The categories of dosages are 50-100 kg/ha of N, and 100-200 kg/ha of P and k, respectively.
