稀土元素在小麦体内分配行为的研究

The distributive behavior of rare earth elements in wheat

采用水培、土培试验及中子活化分析技术 ,在作物生长效应曲线研究的基础上 ,系统地研究了稀土元素在作物体内的含量、吸收、分布和转移等行为。所获结果表明 ,各稀土元素在作物体内的分配行为受生物的内外因素与稀土来源、自身特征和元素间关系的影响 ,是作物稀土元素分配行为已有研究成果的重要补充与深化 。

On the basis of plant growth curve study,which was conducted under soil and water culture,the distributive behavior,such as content,uptake,distribution,translocation of rare earth elements(REEs)in wheat plants was studied.REEs were determined by INAA.With the results gained,our previous knowledge about REEs distributive behavior is significantly replenished and intensified.
