摘要

利用仪器中子活化分析测定玉米不同生长期不同部位的单一稀土含量。结果表明：稀土元素在玉米植株体内主要是向结实及生命活动旺盛部位运转。玉米植株在生长各阶段对元素La，Ce，Nd的吸收最为敏感。这3种元素可能是作物体内活性物质的主要激活剂。

Abstract

The content of single rare--earth element at different stages and positions in corn were measured by INAA.The results show that rare--earth element absorbed by corn is mainly transported to the ripening and high living positions

corn absorbs La

Nd sensitively in each growing stage.The three elements are probably main active material in crops.
