| 摘 要： | 在海南的岛东林场、乐东阳光、陵水福田、陵水六合、乐东千家基地5个具有代表性的芒果种植区,选择长势正常的果树随机进行样品采集,分析第一、二蓬叶中N、P、K、Ca、Mg、S 6种矿质养分含量,对‘红金龙’芒果叶片进行矿质养分的变化规律分析,确定进行叶片养分诊断的适宜采样时间和适宜采样指标,为确定‘红金龙’芒果营养诊断指标提供参考依据。研究红金龙第一、二蓬叶片的N、P、K、Ca、Mg、S 6种矿质营养元素在不同月份的变异系数和平均值。结果表明：12月份第二蓬叶N、P、K、Ca、Mg、S 6种矿质元素变异系数小,且叶片矿质元素含量稳定能代表全年树体营养状况。故‘红金龙’叶片营养诊断在12月采集第二蓬叶作为测定N、P、K、Ca、Mg、S 6种矿质养分较为适宜,营养诊断指标值：氮14.74~18.28 g/kg,磷0.99~1.33 g/kg,钾8.98~12.1 g/kg,钙21.91~30.03 g/kg,镁1.77~1.89 g/kg,硫1.25~1.51 g/kg。

| Abstract: | The leaves of normal mango fruit trees in the representative mango planting areas of East Forest Farm Base, Ledong Sunshine, Lingshui Futian, Lingshui Liuhe, and Ledong Qianjia Base in Hainan were randomly collected to analyze the first and second tents. The contents of N, P, K, Ca, Mg and S in the leaves were analyzed to determine the nutrient diagnosis of the leaves and appropriate sampling time and indicators. The variation coefficients of N, P, K, Ca, Mg and S of the second blade leaves in December were small, which could represent the nutrient status of the whole year. Therefore, it is suitable to analyze the content of the six minerals of the second blade leaves of Hongjinlong in December to evaluate the mineral nutrition. The nutritional diagnostic indicator are nitrogen 14.74-18.28 g/kg, phosphorus 0.99-1.33 g/kg, potassium 8.98-12.1 g/kg, calcium 21.91-30.03 g/kg, magnesium 1.77-1.89 g/kg, sulfur 1.25-1.51 g/kg. |
