摘　　要：[目的]探索土壤中的中量和微量元素含量及其与咖啡豆杯测品质之间的相关性。[方法]通过对普洱市5个县(区)10个咖啡种植园土壤中的中量和微量元素有效含量进行检测分析。[结果]土壤pH为3.77~5.28,为酸性,土壤交换性钙、交换性镁、有效硼、有效钼含量为低水平,土壤有效锌、有效铜含量处于中水平,土壤有效铁、有效锰含量处于高水平;有效硫含量样点间差异较大,6个处于较低水平,4个含量较高;有效铜和有效锰之间相关性达到显著水平,交换性钙和交换性镁之间呈极显著相关;大部分杯测品质指标之间差异呈显著或极显著相关;土壤交换性钙、交换性镁、土壤有效硫、铁、锰、硼、硼、钼、铜与咖啡豆杯测品质的相关性均不显著。[Objective]To explore the correlation between the content of medium and trace elements in soil and the quality of coffee bean cup test.[Method]The effective content of trace and medium elements in the soil of 10 coffee plantations in 5 counties(districts)of Pu’er City was tested and analyzed.[Result]The soil pH was 3.77-5.28,which was acidic,the contents of exchangeable calcium,exchangeable magnesium,available boron and available molybdenum were low,the soil available zinc and available copper were at the medium level,soil available iron and available manganese were at high levels.There were significant differences among the available sulfur samples,with 6 at a low level and 4 at a high level.The correlation between available copper and available manganese reached significant level,the correlation between exchangeable calcium and exchangeable magnesium was extremely significant;there was significant or extremely significant correlation between most of the cup quality indexes;soil exchange calcium,exchange magnesium,soil effective sulfur,iron,manganese,boron,molybdenum and copper were not significantly correlated with coffee bean cup test quality.
