摘要
对陕南主要茶区进行了茶叶和茶园土壤的系统采样和分析,并对富硒茶的硒量作了初步探讨.建议用富硒茶作为低硒区人体硒的补充来源.讨论了富硒保健茶的含硒标准.提出了陕南富硒保健茶的分布范围和含硒水平.
The selenium contents of tea from southern Shanxi were investigated and the data collected indicated that the biasdistributed selenium contents of the coarse-made tea range from 14.29 to 1892.41 ppb with an average of 260.3 ppb, which is lower than that from other areas. The contents of water soluble Se in soil of the area are significantly correlated with those in tea. The relatively high Se contents in tea were found at some isolated spots where metamorphic rocks of the Paleozoic Era are distributed.
