摘要

番荔枝果樹噴施萃取液肥試驗結果顯示，噴施稀釋200倍、400倍及800倍萃取液肥三處理之葉片氮含量顯著高於對照組，噴施稀釋200倍及400倍萃取液肥之兩處理之葉片磷、鉀、鈣及鎂含量與微量元素鐵、錳、銅及鋅含量均顯著高於對照組；噴施稀釋200倍萃取液肥處理之果實單粒重、可溶性固形物含量及單株果實產量分別為605.8克、22.9°Brix及19.1公斤均顯著高於對照組之果實單粒重、可溶性固形物含量及單株果實產量分別為587.2克、20.6°Brix及17.7公斤，噴施稀釋400及800倍萃取液肥兩處理之果實單粒重、可溶性固形物含量及單株果實產量也高於對照組，顯示施用萃取液肥可減少化學肥料用量及提升葉片營養元素含量，且對於果實品質亦有正面的效果。

The results analysis of sugar apple applied extraction liquid fertilizer experiment showed the leaf nitrogen concentration of 0.5%, 0.25% and 0.125% treatments were significantly higher than the control, the leaf phosphorus, potassium, calcium, and magnesium and iron, zinc, copper, manganese concentrations of 0.5% and 0.25% treatments were significantly higher than the control. The fruit weight, total soluble solid content and fruit yield per plant of the 0.5% extraction liquid fertilizer treated plot were 605.8 g, 22.9°Brix and 19.1 kg were significantly higher than the control (587.2 g, 20.6°Brix and 17.7 kg). The fruit weight, total soluble solid content and fruit yield per plant of 0.25% and 0.125% extraction liquid fertilizer treatments were higher than the control. According to the result of experiment, application of extraction liquid fertilizer reduced chemical fertilizer rate and increased the leaf nutrients concentration and had positive effects on the yield and quality of fruit.
