| 中文摘要: |
| 在广东郁南无核黄皮果实膨大期，对不同形态叶片和果实中矿质营养含量进行测定。结果表明，成熟叶片中氮（28.76g/kg）、钾（19.81 g/kg）、锰（275.28mg/kg）、铁（162.17 mg/kg）丰富或者极丰富，磷（1.14g/kg）、铜（6.65mg/kg）、钼（0.24 mg/kg）、锌（40.84 mg/kg）为正常范围，而钙（20.96 g/kg）、镁（2.07 g/kg）、硼（9.35mg/kg）含量处于缺乏状态；幼叶、成熟叶和老叶中氮、钙、镁、硼、锰含量显著高于果皮和果肉，磷、铜、铁、钼含量与果皮、果肉均无显著差异；果皮中硼含量和叶片中磷、钼含量极显著正相关，果皮中镁含量则与这两种元素负相关。建议施肥时应控制大量元素和锰元素，增加钙、镁、硼等中微量元素肥料，可于无核黄皮生长早期进叶面喷施，并可以在果实膨大期直接向果实喷施。 |

| In this experiment, the variations of the contents of the mineral elements in leaf and pericarp at enlargement fruit stage of Yunan Seedless Wampee had been studied. The results were shown as follows: N（28.76g/kg）, K（19.81 g/kg）, Mn（275.28mg/kg）,Fe（162.17 mg/kg） elements were abundant in adult leaves, and P（1.14g/kg）, Cu（6.65mg/kg）, Mo（0.24 mg/kg）, Zn （40.84 mg/kg）elements in normal range, while Ca（20.96 g/kg）, Mg（2.07 g/kg）, B（9.35mg/kg） elements in lack. The contents of N, Ca, Mg and Mn elements in leaves was larger than fruit. There were no significant differences in P, Cu, Fe , Mo content in pericarp and pulp, and P and Mo elements significantly positive correlation B, but negative correlation Mg. The experiment data showed that fertilization should control a large number of elements and increased Mg, Ca, B elements. The foliar application timing of fertilizations can be in growth early, and spraying to the fruit directly in the stage of fruit enlargement. |
