摘要：

通过对海南省三亚市金煌芒果叶片中N、P、K、Ca、Mg、S、Fe、Mn、Cu、Zn、B十一种营养元素含量进行全年跟踪分析，结果表明：⑴金煌芒果叶片养分年平均含量大小为：N>Ca>K>Mg>P>S>Mn>Fe>B>Zn>Cu，其中N、Ca含量较高，P、Mg、S、Zn含量月变化不明显。⑵金煌芒果的生长周期可分为4个阶段:营养生长期(5～9月)、生殖生长期(9～11月)、果实膨大期(11～2月)和果实成熟期(2～4月)。各阶段叶片养分含量变化规律有所差异: 营养生长期，叶片中营养元素除K、Cu含量有所下降之外，其余营养元素均有不同程度的升高。生殖生长期，叶片中的营养元素N、B、Ca含量上升，其他元素含量有不同程度的下降。果实膨大期，叶片中的N、K、Fe、Zn、B含量下降，Ca、Cu、Mn含量上升。果实成熟期，叶片中N、Mn、Fe、B、Cu含量均有不同程度增加，K、Ca含量有所降低。

Abstract:

After monthly sample and analysis the eleven nutrient elements such as Nitrogen,Phosphor,Potassium,Calcium,Magnesium,Sulfur,Iron,Manganese,Cuprum,Zincand Boron contend in Jinhuang mango leaves in Sanya in Hainan for a whole year.The results shown as follows:⑴The annual average nutrition content in Jinhuang mango leaves are N>Ca>K>Mg>P>S>Mn>Fe>B>Zn>Cu,and the content of Nitrogen,Calcium in higher levels , the content of Phosphor,Magnesium,Sulfur and Zinc in leaves fluctuated slightly.⑵We can divided the whole growth cycle of Jinhuang mango to four phases:vegetative growth phase,which is from May to September;reproductive growth phase,which is form September to December;fruit enlargement phase,which is from December to February;fruit maturation phase,which is from February to April.The change rules are not the same in different phases:during the vegetative growth phase,the content of all nine nutrient elements in leaves increased but Potassium, Cuprum declined;during the reproductive growth phase,the content of Nitrogen,Boron,Calcium in leaves increased,and the other declined;during the fruit enlargement phase,the content of Nitrogen,Potassium,Iron,Zinc,Boron in leaves declined,the content of Calcium,Manganese,Cuprum in leaves increased;during the fruit maturation phase,the content of Nitrogen,Manganese,Iron,Boron,Cuprum in leaves increased in different degrees,the content of Potassium, Calcium in leaves declined.
