答：针对我国南方香蕉主产区多为降雨量大、养分淋失量严重等制约因素，为提高肥效，香蕉测土配方施肥要做到以下几点：
（1）勤施薄施重施相结合
在高温多湿季节，正是香蕉旺盛生长期与花芽分化期，此期需肥量大，但施于根部的肥料易流失和分解。因此，应根据香蕉周年生长的特点及多造蕉栽培要求，要勤施薄施，并结合重施，才能及时满足香蕉这两个重点营养期的需肥量，充分发挥肥效。因为营养生长期和花芽分化期是施肥的关键时期，勤施重施薄施相结合，是最佳的施肥方法。
（2）以有机肥为主，有机无机肥料混合施用
实践证明，有机肥可改良土壤结构，调节土壤水肥气热理化性状，有助于香蕉根系生长发育。化肥肥效迅速，但肥劲短而不稳，有机与化肥配合施用，可使蕉株健壮，抗性强，生长快，早结果，品质优。
（3）准确掌握施肥深度与位置
把握施肥深度与位置的原则：一是肥随芽走，即施在萌芽位置；二是经常轮换施肥位置，并施于吸收根群密集伸展与活动区。春秋季深开穴，夏季可浅开穴，肥多大穴肥少小穴，施后覆土踏实，防止流失。
一般情况下都是全元素复合肥比较好，
生长更好更快更旺，结果更多更大，
香蕉喜肥水，每次浇水时可以加点全元素复合肥
新种香蕉苗施用黑老虎复合微生物肥硫基6两，成年香蕉树施用1斤左右做基肥，香蕉明显根系发达、叶片肥厚、树型健壮、结果多，每棵都结了7--10把、25公斤以上，按每亩120棵计，亩产量预计超过30000斤。黑老虎复合微生物肥对酸性土壤有很好的改良和修复作用。而且用过黑老虎复合微生物肥后，香蕉品质有提高，1、2级果品占80％以上。”
