| 摘 要： | 在渔塘坝０．０１ｋｍ＾２的微域内，玉米硒含量达到较高水平，其根，茎，叶，籽中的平均硒含量分别是４．３６±３．２７ｍｇ／ｋｇ，３．０８±２．２４ｍｇ／ｋｇ，９．７４±７．６２ｍｇ／ｋｇ和８．０７±５．０２ｍｇ／ｋｇ。渔塘坝中玉米硒分布类似土壤分布，也可分出相对低，中、高硒的分布区。

| Abstract: | Within the range of 001km2 minilandscape in Yutangba,Enshi,Hubei province,Se content in corn is very highThe average Se contents in root,stem,leaf,seed of corn are 436327mg/kg,308224mg/kg,974762mg/kg,807502mg/kg,respectivelyThe research results show that there is a significantly positive relationship between in selenium corn and soil,and the distribution of Se level in corn in Yutangba can be divided into three subregionsSe contents in soil almost control that in corn,and the tiny change of the former can lead to the considerable change of the latterAccording to it,these organs with relatively higher Se in plants may be used as a sensitive selenium indicator of Se levels in environment |
