摘要
以云南玉溪5个高产冰糖橙果园、5个中低产果园、5个幼龄果园的果实为试材,测定了果实的矿质营养元素含量及果实品质。结果表明:云南不同产量冰糖橙果园果实N、K、Ca、Mg、Zn元素含量差异较大,高产果园果实Ca、Mg、Zn元素含量较高,与中低产果园、幼龄果园存在显著性差异;幼龄果园N、K含量较高,与高产、中低产果园存在显著性差异;高产果园果实大小适中、内部品质最佳。冰糖橙果实N、P、K含量与可溶性固形物、固酸比含量呈极显著或显著负相关,与可滴定酸含量呈显著或极显著正相关;果实中Ca和Zn含量均与可溶性固形物、固酸比呈显著或极显著正相关,与可滴定酸含量呈显著或极显著负相关;N含量与单果重、纵横径呈显著正相关;果实可食率与Mg含量呈显著正相关,与P和Cu含量呈显著负相关,生产上需要重视补充Ca、Mg、Zn肥,控制N、P、K肥的施用量。
To explore the correlation between fruit mineral element contents and fruit quality of bingtang sweet orange in Yunnan province of china. Nine nutrient elements in fruit and the quality of bingtang sweet orange were investigated in 15 different orchards in Yunnan province. The results showed that the fruit N, K, Ca, Mg and Zn levels differed sharply from different orchards. The fruit Ca, Mg and Zn levels of high yield orchard were maximum and they had significant difference between middle–low yield orchard and young orchard. The fruit N and K levels of young orchard were maximum and they had significant difference between high yield orchard and middle–low yield orchard. The correlation coefficient between the fruit mineral element contents and fruit quality showed that the fruit N element content had a significantly positive correlation with the fruit weight, longitudinal diameter, transverse diameter and titratable acid（TA）. And it had a significantly negative correlation with edible rate, fruit total soluble solid（TSS） content and TSS/TA ratio. The fruit P element content had a significantly positive correlation with titratable acid（TA）. And it had a significantly negative correlation with the fruit edible rate, total soluble solid（TSS） content and TSS/TA ratio. The fruit K element content had a significantly positive correlation with the fruit titratable acid（TA）. And it had a significantly negative correlation with the fruit total soluble solid（TSS） content and TSS/TA ratio. The fruit Ca element content had a significantly positive correlation with the fruit total soluble solid（TSS） content and TSS/TA ratio. And it had a significantly negative correlation with the fruit titratable acid（TA）. The fruit Mg element content had a significantly positive correlation with the fruit TSS/TA ratio and it had a significantly negative correlation with the fruit titratable acid（TA）. The fruit Zn element content had a significantly positive correlation with the fruit edible rate, fruit total soluble solid（TSS） content and TSS/TA ratio. And it had a significantly negative correlation with the fruit titratable acid（TA）. The fruit Cu element content had a significantly negative correlation with edible rate. Furthermore, the fruit quality and yield of bingtang sweet orange were regulated by the synergistic effects of various mineral elements. For the fertilizer practices of bingtang sweet orange in Yunnan province, it should be focused on supplementing Ca, Mg and Zn,decreasing in N, P and K applications.
