| 中文摘要: |
| 通过对广西田东地区“桂热芒82”号叶片中N、P、K、Ca、Mg、S6种营养元素含量进行全年跟踪分析，结果表明：“桂热芒82号”生长周期分为4个阶段：营养生长期(8—12月)、生殖生长期(12—2月)、果实膨大期(2-5月)、果实成熟期(5-7月)。叶片养分年平均含量大小为：第一蓬Ca＞N＞K＞Mg＞S＞P、第二蓬Ca＞N＞K＞S＞Mg＞P。各阶段叶片养分含量变化规律有所差异，第一、二蓬叶片变化基本规律一致。第一、二蓬叶片Ca、N、K、Mg、S、P含量（g/kg）为：19.84、15.36、8.34、1.90、1.58、1.32和23.45、14.46、7.22、1.56、1.77、1.18，该品种对钙肥的需求量较大。 |
| 英文摘要: |
| Analyzing six nutrient elements such as Nitrogen, Phosphor, Potassium, Calcium, Magnesium, Sulfur contending in\" Gui re No. 82\" mango leaves in Guangxi Tiandong for a whole year, the results of the experiment are breeding. The results shown as follows: We can divide the whole growth cycle of Gui re \"No. 82\" mango into four phases: vegetative growth phase, which is from August to December; reproductive growth phase, which is form December to February; fruit enlargement phase, which is from February to May; fruit maturation phase, which is from May to July. The annual average nutrition contents in leaves are: first blade: Ca＞N＞K＞Mg＞S＞P, second blade: Ca＞N＞K＞S＞Mg＞P. The change rules are not stay the same in different phases but are consistent between the first and the second blade. The first and second blade Ca, N, K, Mg, S, P content (g/kg)was: 19.84、15.36、 8.34、1.90、1.58、1.32 and 23.45、14.46、7.22、1.56、1.77、1.18. On the application of fertilizer , the amount of calcium fertilizer shoud be increased. |
