摘要
本文研究了贵州茶园土壤中氟、铝的形态组成及分布特征,探讨了彼此间的相关性。研究结果表明:水溶态氟、交换态氟、交换态铝和有机结合态铝是茶树吸收氟和铝的主要物质供应源,彼此间有很好的相关性,且受土壤pH值的影响较大,在茶树的生物富集作用下,茶园土壤中氟和铝均表现出有从土壤深层向表层迁移富集的趋势。
In this paper,species and their distribution characteristics and relationshipsof fluorine and aluminum in the soil from tea farm in Guizhou Province,China were studied.Results show that diffluent and ion state fluorine as well as ion state and organic combination state aluminum,with good relation with each other and being affected seriously by soil pH,are main sources for tea tree from soils.Due to biologic enrichment of tea tree,all of above species of F and Al have the immigration trend fromdeep layer to the surface of the soil.
