| 摘要：在海南热带地区，采用植株解析法对“巴西”蕉和“宝岛”蕉两个主栽香蕉品种各生育期不同器官的氮、磷、钾含量进行测定，分析香蕉生长发育过程中氮、磷、钾的积累和分配规律，为热带地区香蕉栽培施肥及营养管理提供理论参考。研究结果表明，两品种香蕉全生育期不同部位氮磷钾含量及累积量特征一致均为K>N>P。收获期，两品种香蕉叶中氮含量显著高于其他部位，果柄中的磷和钾含量显著高于其他部位。两品种相同部位氮磷钾含量及累积量不同，两品种的营养特征相同，对氮磷钾的分配规律基本一致。 |

| Abstract: In Hainan tropical regions, using the analytic method of “BaXi” and “BaoDao” two main banana plant varieties in each growth period of different organs of N, P and K concentrations were determined, This paper analyzes the accumulation and distribution of N, P and K in the growth and development of bananas, and provides theoretical reference for the banana cultivation and nutrition management in tropical regions. Research results show that, the content and accumulation of NPK in different parts of the two varieties of banana, All of them are K >, N > P. In the harvesting time , the nitrogen content of the two varieties of banana leaf was significantly higher than that of other parts, the content of phosphorus and potassium in the stalk was significantly higher than that of other parts. The content of NPK and the cumulative amount of nitrogen in the same part were different, the nutritional characteristics of the two varieties are the same, the distribution of NPK are basically consistent. |
