摘要

本田間試驗於2008年至2009年在新北市八里區及新竹縣寶山鄉進行，探討文旦果樹氮肥及鉀肥施用量對果實產量及品質之影響。另，每月定期採取文旦葉片分析其養分含量，以訂定文旦葉片最佳採樣時期、部位及各要素適宜濃度範圍，供葉片營養診斷及施肥推薦用。試驗結果顯示，文旦以施用氮1,000 g plant^(-1)及氧化鉀1,000 g plant^(-1)對果實品質及產量為最佳。葉片採樣最佳時期為5－6月間，採樣部位則為春梢非結果枝第三片葉，各要素適宜濃度範圍值為氮2.4-2.6％，磷0.13-0.15％，鉀1.70-2.05％，鈣1.72-2.94％和鎂0.21-0.34％。

The field trials were conducted to study the effect of application rates of nitrogen and potassium on the fruit yield and quality of Wentan pomelo, to determine the sampling time of leaves for diagnotic of nutrient status and to establish the diagnosis standard of nutrient levels of leaves at Bali and Baoshan countries in 2008-2009. The results showed that 1,000 g/plant of nitrogen and potassium oxide used were the highest yield and quality of Wentan pomelo. The adequate time was in May and June. The leaf for diagnosis was the third leaf of non-bearing branches growing in the spring. The optimum range of nutrient concentration were 2.4-2.6% for nitrogen, 0.13-0.15% for phosphorus, 1.70-2.05% for potassium, 1.72-2.94% for calcium, and 0.21-0.34% for magnesium.
