摘　　要：通过项目区３７个小流域的土壤调查及４２个土壤剖面观测和样品测试的结果，文章重点讨论分析项目区内花岗岩类、火山岩类、沉积岩类、变质岩类及第四纪红土等５种风化壳及其发育的土壤中，Ｃｕ、Ｚｎ、Ｆｅ、Ｍｎ、Ｂ、Ｃａ、Ｍｇ等７种微量营养元素的有效态含量、分布特征及其农业效应。并阐明在水稻生产与果、茶园开发利用中，应重视这些微量营养要素的农业调节措施。This paper dealt with the relationship between the geological characteristics and the micronutrient requirement of the weathering crusts developed from granite, volcanic rocks, sedimentary rocks, metamorphic rocks, and Quaternary deposits in the project areas The available contents, the distribution characteristics and the agricultural effect of the micronutrients, and the agricultural measurements for adjusting the micronutrient status in tea plantations, orchards and rice fields were also discussed

关 键 词：微量营养元素 地质特点 农业效应
