中文摘要 | 本試驗擬由楊桃施肥量與不同採樣時期、部位之葉片養分含量及其產量、糖度之三者相關性,探討其葉片養分含量之適宜標準範圍,並訂定營養診斷時葉片之採樣時期與部位及其適宜肥料施用量,以提供營養診斷之施肥推薦及農民施肥之參考。試驗結果顯示楊桃葉片養分含量受結果與否之影響極大,另葉齡影響葉片養分含量之程度較樹齡為大,經由不同部位葉片養分含量周年變化之情形觀之,楊桃葉片之採樣方法可暫定為7-8月間採取未結果枝條頂端算起第5葉,且其適宜範圍暫定為N: 18-24 g/kg,P: 1.0-1.4 g/kg,K: 14-20 g/kg,Ca: 10-16 g/kg,Mg: 5.0-7.0 g/kg,Fe: 60-180 mg/kg,Zn: 70-150 m g/kg,Cu: 5-15 mg/kg,B: 50-90 mg/kg,而施肥量N-P2O5-K2O=400-300-600g/株/年處理之楊桃糖度9.2°Brix及產量131 kg/株為最佳,可供農民施肥之參考。 |
英文摘要 | The experiment was conducted to find out the proper sampling method in carambola and optimum ranges of inorganic nutrient of leaves as standard to recommend the application of fertilizer rates. The results were showed: The leaf nutrients of carambola were influenced by fruiting. The leaf age influenced the leaf nutrient contents more than the tree age. The fifth leaves of non-fruiting branch were sampling during July to August were suitable to diagnosis the leaf nutrition status of carambola. The optimum ranges of leaf nutrition in carambola were tentatively fixed at N: 18-24 g/kg, P: 1.0-1.4 g/kg, K: 14-20 g/kg, Ca: 10-16 g/kg, Mg: 5.0-7.0 g/kg, Fe: 60- 180 mg/kg, Zn: 70-150 mg/kg, Cu: 5-15 mg/kg, B: 50-90 mg/kg. The sweet degree and yield of carambola with application the N-P2O5-K2O = 400-300-600 g/plant/year were 9.2°Brix and 131 kg/plant respectively, and was the best among the treatments. |
