在实验室条件下分别对5个不同香蕉品种幼苗进行常规施肥管理，并对其长势和倒2叶的N、 P、 K、 S含量进行观测和测定。结果表明：5个参试品种的假茎粗和假茎高增大趋势无显著差异，巴西蕉和贡蕉绿叶数有所减少。5个参试品种中，幼苗叶片N含量大小顺序为：巴西蕉＞广粉1号＞贡蕉＞粉杂1号＞热科1号； P含量大小顺序为：贡蕉＞巴西蕉＞广粉1号＞热科1号＞粉杂1号；贡蕉和热科1号幼苗叶片K的含量较大，粉杂1号最小；而含S量大小顺序为：广粉1号＞粉杂1号＞贡蕉＞热科1号＞巴西蕉。5个参试品种叶片的N、 P、 K、 S含量的大小顺序一致，均为为： N＞K＞P＞S。%To discuss different varieties of banana seedlings growth and nutrient contents characteristics, the growth of five different banana varieties and the contents of N, P, K and S were studied under the condition of laboratory. The results showed: there're no significant difference of the changeable trend based on the thickness and height of the 5 kinds of banana pseudo-stems, but the leaves of BaxiJiao (Musa AAA Cavendish) and Gongjiao (Musa AA Sucrier) decreased. Among the five varieties of banana samples, the content of N was found to follow the order: Baxi Jiao (Musa AAA Cavendish) > Guangfen No.1 >Gongjiao (Musa AA Sucrier) > Fenza No.1 > Reke No.1; the content of P was found to follow the order:Gongjiao>Baxi Jiao>Guangfen No.1>Reke No.1>Fenza No.1;Gongjiao and Reke No.1 were higher than other there varieties in the content of K, while Fenza No.1 was the lowest. At the same time, the content of S was found to follow the order: Guangfen No.1 > Fenza No.1 > Gongjiao > Reke No.1 >Baxi Jiao. The performance of the five varieties leaves' samples was found to be consistent on the content of N, P, K, S, which was N>K>P>S.
