摘要: 本省北、中部部分枇杷園土壤酸性強,土壤內交換性鈣及交換性鎂較低。在幼果期葉片氮量高時,葉內磷、鎂及碳水化合物含量低。果形大時,果汁內可溶性固形物量及果酸量有較低趨勢。枇杷葉片適宜養分濃度:N:2.00,P:0.13,K:2.26,Ca:1.90,Mg:0.38。
Soil pH and exchangeable calcium and magnesium were lower in some of the northern and central loquat orchards. The higher the nitrogen applied the lower the concentration of phosphorus, magnesium and soluble carbohydrate in leaves. The concentration of total soluble solids and acids in juice generally decreased as fruit size increased. Yhe optimum nutrient concentrations of mature loquat leaves were N:2.00%, P:0.13%, K:2.26%, Ca:1.90% and Mg:0.38%.
