摘要
对四川茶区黄壤中有机质与微量元素的相互关系研究表明,当有机质含量为0.97％至7.0％时,Al、Ca、Zn仝量随之增大,有机质含量为0.9％～15.9％时,土壤仝镁量与有机质呈极显著正相关,茶园土壤中腐殖质总量与Cu、Zn有效量呈极显著正相关。
An investigation of soil organic matter and trace elements in major tea-producing areas of Sichuan showed that total Al, Ca and Zn increased as the organic matter in the soil rose from 0.97% to 7% and that total Mg had a highly significant positive correlation with soft organic matter when the latter was in the range of 0.9%～15.9%. A significant positive correlation existed between the total amount of soil humus and the availablity of Cu and Zn.
