用原子吸收光度法对多年套种在同一高硒田块上的３种作物硒含量及其形态进行了比较研究。结果表明：作物集累的硒８０％以上是以有机结合形态存在的；作物集累硒的总量和硒在各种结合形态中的分布与作物种类有关。
The selenium content and its morphology of three kinds of crops interplanted in the same high selenium field for many years were compared by atomic absorption spectrophotometry. The results showed that more than 80% of selenium accumulated in crops existed in the form of organic combination. The total amount of selenium accumulated in crops and the distribution of selenium in various combinations were related to crop types.
