摘要

为探究土壤性质对茶叶品质的影响程度

采用通径分析法研究了贵州省主要名优绿茶产地土壤性质对茶叶中水浸出物、茶多酚、儿茶素、咖啡碱的直接和间接效应。研究结果表明

土壤性质与茶叶品质之间的相关性不明显

土壤对茶叶品质影响程度表现为:咖啡因>儿茶素>水浸出物>茶多酚

决定系数分别为:0.854

0.830

0.787和0.705

剩余项系数分别为:0.382

0.412

0.462和0.543

土壤性质能表达影响茶叶品质众多因素中50%以上的信息。

Abstract

In order to study the impacts of soil properties on the quality of tea

path analysis method was used to analyze the direct and indirect effects of soil properties on water extracts

polyphenols

catechins and caffeines of tea in the main region of famous green tea-producing area in Guizhou Province.The results showed that there was no significant correlation between the soil properties and quality of tea.The impact of soil on quality of tea was caffeines>catechins>water extracts>polyphenols

the determinative coefficients were 0.854

0.830

0.787and 0.705

respectively

and the residual coefficients were 0.382

0.412

0.462and 0.543

respectively.The results also showed that soil properties could express more than 50%factors that influence tea quality.
