  • 摘要: 研究了安徽宣城、六安和合肥茶区不同茶园土壤氟含量及在茶树体内的富集与转运特征,探讨了茶树根际和非根际土壤氟的有效性特征及其在茶树体内的累积规律.结果表明,安徽省典型茶园表层土壤全氟含量为:六安黄棕壤(319.7 mg·kg-1)>宣城黄红壤(316.6 mg·kg-1)>合肥黄褐土(311.3 mg·kg-1),均低于我国土壤总氟背景值(478 mg·kg-1),并呈现一定的表层富集现象.表层土壤的水溶性氟含量则为:合肥黄褐土(5.32 mg·kg-1)>宣城黄红壤(3.32 mg·kg-1)>六安黄棕壤(2.65 mg·kg-1),根际土壤中水溶性氟含量也高于非根际土壤.不同茶园茶树体内氟含量有较大差异,但均呈现成叶>落叶>嫩叶>根、茎的规律.茶树嫩叶氟含量在108.2-184.3 mg·kg-1之间,低于农业部茶叶氟含量安全限量标准(≤200 mg·kg-1);而成叶中氟含量较高(531.0-1155.2 mg·kg-1).茶树对土壤氟具有较强的富集和运输能力,茶园表层土壤全氟和水溶性氟在茶树成熟叶片的富集系数分别在1.71-3.65和99.8-348之间,氟由根部向叶片的转移系数在9.7-25.5之间.研究结果可为土壤氟在茶树体内的富集及其对茶叶质量安全的影响评价提供依据.
    Abstract: Bioaccumulation and translocation of fluoride from soils to different parts of tea plants from several tea plantations of Xuancheng, Liu'an and Hefei in Anhui Province were investigated by sampling tea garden soils and tea plants. Results revealed that the total fluoride concentrations in surface soil (0-20 cm) in tea plantations from Liu'an (319.7 mg·kg-1) were higher than those in Xuancheng (316.6 mg·kg-1) and Hefei (311.3 mg·kg-1), respectively. these fluoride contents were lower than the national fluoride background level (478 mg·kg-1). The fluoride concentrations in surface soil were higher than those in the subsoil profile (20-40 cm and 40-60 cm), indicating that a large amount of fluorides were enriched in the surface soil. The soluble fluoride in rhizosphere soil was higher than that in the non-rhizosphere soil from different tea planting areas. The fluoride contents in the different parts of tea plants were in the order of: mature leaf>fallen leaf>young leaf>root, stem. In young leaves, the fluoride contents (108.2-184.3 mg·kg-1) were below the national fluoride limit in tea (≤200 mg·kg-1), while in mature leaves, the fluoride contents (531.0-1155.2 mg·kg-1) were above the limit, which pose potential risks to tea quality. The bioaccumulation factors (BF) of total and soluble fluorides from surface soil to tea plant ranged from 1.71 to 3.65, and from 99.8 to 348, respectively. The translocation factors (TF) of fluorides from roots to mature leaves ranged from 9.7 to 25.5, indicating that the ability of fluoride translocation from roots to leaves were higher in tea plants.
