【摘要】 本文应用同位素示踪技术,研究了稀土元素¹⁴¹Ce在甜菜植株中的吸收、分布和积累。结果表明,甜菜对¹⁴¹Ce的吸收很迅速,在块根膨大期吸收更为强烈,吸收率可达39.45％。¹⁴¹Ce在植株各器官的分布与积累规律是叶>叶柄>根。更多还原

【Abstract】 This paper is concerned with absorption, distribution and accumulation of rare earth in sugarbeet by applying isotopic technique. The experimental results indicated that absorption of beet on rare earth 141Ce very fast. The uptake rare of 141Ce by sugarbeet plant is about 39.45%. Distribution and accumulation of rare earth 141Ce in the plant was as follow; Leaves>Leaf stalk>Root.更多还原
