用等离子体发射光谱仪分析测定了４９个水稻品种（其中有４５个黑稻品系、４个白米品种）的糙米和１２个水稻品种的精米中铁（Ｆｅ）、锌（Ｚｎ）、钙（Ｃａ）、硒（Ｓｅ）四种矿质原素的含量。给果表明：４５个黑稻品系的Ｆｅ、Ｚｎ、Ｃａ、Ｓｅ四种矿质元素的含量变幅分别为３．６～７５．７１、１５．２４～９５．２７、８３．３７～４０７．０８、０．０１８７～０．０８５１（μｇ／ｇ），品系间四种元素的含量差异很大；除Ｓｅ的含量白米显著高于黑米外，Ｆｅ、Ｚｎ、Ｃａ的平均含量白米和黑米间无显著差异；糙米中四种矿质元素的含量高于相应的精米；稻米中Ｚｎ和Ｃａ的含量有极显著的正相关关系。
The contents of iron (Fe), zinc (Zn) and calcium (Ca) in polished rice of 49 rice varieties (including 45 black rice lines and 4 white rice varieties) and 12 rice varieties were determined by using plasma emission spectrometer. Selenium (Se) four mineral elements content. The results showed that the content of four mineral elements of Fe, Zn, Ca and Se in 45 black rice lines ranged from 3.6 to 75.71, from 15.24 to 95.27, from 83.37 to 407.08 , 0.0187 ~ 0.0851 (μg / g). The content of four elements in the two strains varied greatly. The average content of Fe, Zn and Ca except white rice was significantly higher than that of black rice There was no significant difference between them. The contents of four mineral elements in brown rice were higher than those in polished rice. There was a significant positive correlation between Zn and Ca in rice.
