| 摘 要： | 以云南河口县蕉园巴西香蕉为试验材料,分析了不同生长期(营养生长期、花芽分化期、现蕾开花期、果实生长期)不同器官(根、茎、叶)氮、磷含量及其变化规律.结果表明:香蕉植株根、茎、叶在整个生长期氮(N)含量分别在0.496％～0.675％、0.864％～0.923％和1.096％～1.457％之间.磷含量(P2O5)分别在0.088％～0.224％、0.123％～0.394％和0.157％～0.351％之间.从不同器官看,在整个生育期中,含氮量总体表现为叶＞茎＞根.含磷量在花芽分化期与现蕾开花期:叶与茎＞根；营养生长期:茎＞叶＞根；果实生长期:叶＞茎＞根.

| Abstract: | The Brazil banana was chosen as test material,analysed of the different growth stages(vegetative growth stage,flower bud differentiation stage,squaring stage,fruit growth stage)in different organs(roots,stems,leaves)of nitrogen and phosphorus content and its variation law.The results showed that nitrogen contents of roots,stems and leaves were 0.496%~0.675%,0.864%~0.923% and 1.096%~1.457%.Phosphorus contents of roots,stems and leaves were 0.088%~0.224%,0.123%~0.394% and 0.157%~0.351%.View from the different organs,in the whole growth period,between different organs of the general result,nitrogen contents of leaves were significantly higher than stems,stems were significantly higher than root;phosphorus contents in the flower bud differentiation stage and squaring stage,leaves and stems were significantly higher than root;In the vegetative growth stage,stems were significantly higher than leaves,leaves were significantly higher than roots;In the fruit growth stage,leaves were significantly higher than stems,stems were significantly higher than the roots. |
