对山东主要产茶区的土壤与茶(Camellia sinensis L.)叶中大量元素和微量元素含量进行了比较分析和线性相关分析。结果表明,山东主要茶区茶树对主要元素的吸收量依次为N>K>P;各茶区土壤中Mn和Zn含量极度缺乏;部分茶园土壤Ca和Mg含量比例失调。建议在加强N肥使用量的同时,加大微量元素肥料用量。鲁中山区茶区应减少K肥的使用量;鲁南山区应增加P和K肥的使用量。

The contents of macroelement and microelement in soil and tea ( Camellia sinensis L. ) leaves of main tea regions in Shandong Province were determined and analysed. The results indicated that the absorption ratio of tea tree to main elements was in the order of N >K >P. The soil lacked microelements in all tea regions, especially Mn and Zn. The proportation of Ca and Mg was misadjustment. So it was suggested that supply of microelement should be increased while keeping the higher use of N fertilizer, and reduce to use K fertilizer in the tea region of the middle of Shandong, and increase to use P and K fertilizers in the south of Shandong.
