| 摘 要： | 建立富硒土壤地方标准对促进富硒产业发展具有积极意义。笔者分析了西北各省富硒土壤标准制定现状,基于在甘肃全省范围内协同采集的304件土壤及小麦籽实样品分析数据,通过富硒小麦的下限值及籽实与根系土中Se的线性相关模型,推导出0.28×10^-6作为甘肃省富Se土壤标准下限,对甘肃省富Se土壤地方标准的建立及富Se土壤资源的科学利用具有指导意义。

| Abstract: | The establishment of local standard of selenium-rich soil is of significance to the development of selenium-rich industry.This paper analyzes the present situation of the establishment in the northwestern provinces.304 samples of soil and wheat seed collected from Gansu province were studied by means of the lower limit and Se linear models of seed and soil,deducing 0.28×10^-6 as the lower limit standard for selenium-rich soil.The study Lays a foundation for the e stablishment of the local standard and the scientific utilization of the selenium-rich soil in Gansu province. |
