通过检测丽水市名茶及普通茶相应茶园土壤养分指标、茶叶品质指标，并运用dps3．0软件，进行多元线性逐步回归分析。结果表明：影响秋茶品质最关键的土壤养分指标是速效氮含量，它与5个茶叶品质指标存在相关性；其次是土壤有机质含量，它与茶叶中的氨基酸、咖啡碱含量和酚氨比呈线性相关。春茶品质主要受速效氮和速效钾含量的影响。丽水市土壤速效氮和有机质含量较高，这是该地区茶叶具有较高品质的主要原因。应保持有机肥、氮肥适量施用，配施钾磷肥，促进茶叶产量及品质的稳步提高。

The soil fertility indexes and tea quality indexes for the ten famous Lishui teas, flower tea and Biluochun tea were analyzed using. The dps3.0 software. The results show that it was the content of the available nitrogen that affected the autumn tea quality most and the linear correlation between available N and five tea quality indexes was significant. The content of organic matter in soil was linearly eorreled to the content of Amino acid. Spring tea quality was mainly affected by the contents of the available nitrogen and the available potassium. Lishui tea soil was rich in available nitrogen and organic matter. To promote the quality and production of tea, we should apply organic manure and nitrogen fertilizer in appropriate amount, together with phosphorus and potash fertilizer.
