Abstract
探討蓮霧營養管理對品質改進效果研究從分析蓮霧園土壤、葉片、果實、果汁營養素結果，顯示施用三要素以外其他元素肥料多少可影響土壤及植株各部位中無機營養成分含量。從相關分析結果無機養分含量與果實糖度有極顯著正相關：在土壤中pH Ca, Mg, Mn, Na，在葉片中Mg, Mn, Na，在果汁中P,K, Mg, Na。由現地試驗結果以及搜集各地區高品質果園土壤及葉片營養素含量暫作蓮霧養分推薦之標準。氮1.26~1.50%，磷0.10~0.12%，鉀1.15~1.45%，鈣1.60~2.00%，鎂0.16~0.20%，錳70~120ppm，鐵100~150ppm，鈉80~250ppm，硼40~80ppm，鋅30~50ppm。以此標準在內埔等品質較差蓮霧果園，實證應用結果，尚屬可行，不但可節省部份肥料及肥料費用，果實發育徒長情形減少，果實品質提高，惟更確實適宜標準，尚需再進一步研究調整。 The objective of this study was to find out the effects of nutrient management on quality improvement in wax-apple. Applying various elements besides nitrogen, phosphorus and potasium to soils and plants affected inorganic nutrient concentration in soil and plant. There was a significantly positive correlation between nutrient concentration and sugar content of fruits. The tentative sufficiency ranges of nutrient elements for wax-apple are N:1.26~4.50%, P:0.10~0.12% , K:1.15~1.45 %, Ca:1.60~2.00%, Mg:0.16~0.20%, Mn:70~l20ppm, Fe:100~450ppm, Na: 180~250ppm, B:40~80ppm, and Zn:30~50ppm.
