| 摘 要： | 对福建省安溪县、华安县、永春县主要铁观音茶生产乡镇的茶园表层土壤和相应茶叶中的镍含量状况进行了调查.结果表明:茶园土壤全镍含量为4.08-123.44 mg.kg-1,平均值19.06 mg.kg-1,绝大部分土壤未受到明显的镍污染,土壤全镍含量与有机质和粘粒含量均呈极显著正相关;土壤有效镍含量为0.12-4.84 mg.kg-1,平均值0.74 mg.kg-1,与土壤阳离子交换量(CEC)和有机质含量呈显著正相关;茶叶镍含量为(3.70±1.52)mg.kg-1.茶叶对镍的吸收富集能力随着土壤镍含量的升高而降低.

| Abstract: | An investigation on the content and availability of nickel(Ni) in the surface soil and its concentration in the tea leaves of the Tieguanyin tea plantations in Anxi County,Yongchun County and Huaan County in Fujian Province was conducted.150 soil samples and the corresponding tea leaves were collected.Ni concentrations in soils and tea leaves,HCl-extractable Ni in the soils,the relationship between HCl-extractable Ni and soil properties,and the transfer characteristics of Ni from soils to tea leaves were st... |
