摘　　要：在天宝蕉产区的农业地质背景和天宝蕉品质分析的基础上,对二者的相互关系进行了研究,得出优质天宝蕉产区的主要农业地质特征是:(1)天宝香蕉的优质区主要分布在九龙江Ⅰ级阶地和红土台地上;(2)优质天宝蕉的成土母质为第四系全新统冲洪积层和第四系残坡积层;(3)优质天宝蕉种植区的土壤主要为灰泥田和赤砂土;(4)天宝蕉优质区成土母质富集元素最多,土壤全量中Na2O、MgO、CaO的含量较高,土壤有效态含量中Cu、Zn元素的含量较高;(5)天宝香蕉优质区的水位埋深较浅,土壤的持水透水能力适中。同时提出了对非优质香蕉的种植区补充土壤营养元素、改良土质和增加蕉园的灌溉等土壤改良建议。Based on the analysis of the agricultural geological conditions and quality of Tianbao banana, this paper discussed the retationship between them, then got the major characteristics of the agricultural geology of Tianbao banana with good quality. （1）Tianbao banana is located mainly at the first level terrace and red soil terrace. （2） The soilforming rocks of elite quality Tianbao banana are Q4 and Q^el. （3） The soils are mostly grey clayed paddy soil and red sandy soil. （4） The soil forming rocks of Tianbao Banana area are rich in nutritive elements, higher in the full contents of Na2O, MgO, CaO and effective contents of Cu, Zn from the view of geochemistry. （5） The conspicuous hydrogeological settings are shallow groundwater and moderate water permeability and water retention property.
