陕西汉阴茶园土壤硒含量及茶叶硒富集能力

研究了陕西省汉阴县茶园土壤硒含量及茶叶硒富集能力.分别采集了陕西省汉阴县典型茶园茶叶及对应土壤样品,并分别采集了茶树不同部位茶叶样品,氢化物原子荧光光谱法测定硒含量,研究茶叶硒富集能力及硒主要分布部位.结果表明,陕西省汉阴龙井长叶茶硒含量高于龙井43号茶,春茶略高于秋茶;茶叶硒富集能力强于其他农作物;硒含量在茶树的分布部位由高到低为毛尖、第一叶、老叶、第二叶、茎.

Soil Selenium Content and Capacity of Enrichment Selenium of Tea Leaves in Hanyin Tea Garden

Soil selenium content and capacity of enrichment selenium of tea leaves in Hanyin tea garden were studied. Tea leaves and corresponding soil samples were collected from the typical tea gardens in Hanyin. And the selenium content was detected using atomic fluorescence spectrometry to study the capacity of enrichment selenium of tea leaves. Different parts of the tea plant samples were also collected to study the ability of accumulating selenium. The results showed that the selenium content of spring tea was higher than autumn tea. And the Longjing long leaf tea was higher than Longjing 43 tea. The capacity of enrichment selenium of tea was higher than other crops. Different parts of the tea plant had different capacity of enrichment selenium the second leaves 〉 stems. Burr And the order was as follows： burr point 〉 the first leaves 〉 old leaves 〉 point with apical dominance had the highest selenium content.
