摘要

采用不同方式将（８９）Ｓｒ引入茶树－土壤系统．结果表明，由茶树地上部引入的（８９）Ｓｒ在茶树叶中的浓度比由土壤引入的高得多；在同一引入处理中，老叶中的（８９）Ｓｒ浓度要比嫩梢高．（８９）Ｓｒ在不同方法引入处理的茶树叶中的消长规律不同：由地上部引入（８９）Ｓｒ的，其在老叶、嫩梢中的浓度随时间延长而减少；由土壤引入的，嫩梢中的（８９）Ｓｒ浓度起初随时间延长而增高，在达到某一值后便缓慢降低，而老叶中的（８９）Ｓｒ浓度起初增加较快，一定时间后便逐渐趋缓并达一饱和值。还确定了嫩梢、老叶对（８９）Ｓｒ的ＣＦ（浓集系数）值．

Abstract

The 89Sr was added to the teatree-soil system by different ways. The 89Sr in to the system through the over-ground part of teatree

was much more than that through soil. The 89Sr concentration in older leaves was higher than in shoot for a definite treatment. The accumulation elimination law of 89Sr in leaves varied with the treatments. For the treatment througn the over-ground part

the 89Sr concentration in older leaves and shoot was monotonously decreased with time increasing. But for the treatment through soil the 89Sr concentration in shoot was increased to reach a peak value

and then decreased slowly; while the 89Sr concentration in older leaves increased quickly in a period

then increased slowly to attain a saturated value.In addition

the concentration factor of 89Sr in older leaves and shoot were determined.
