研究小麦与土壤中微量铜的相关性和生物吸收比特性，以南阳彩色小麦、周麦16、偃展4110为样品，用固定时间—浓度直读法进行快速测定。结果表明：各地区种植的小麦粉中铜含量为2．17～7．81μg／g，蓝麦铜含量较高，周麦16铜含量较低。巩义地区小麦铜含量在4．599～7．808μg／g，高于各品种小麦的本底；郑州地区小麦铜含量在2．17～4．52μg／g，均低于同一麦种的铜含量。小麦的生物吸收比与品种、土壤特性密切相关，周麦16生物吸收比较低，为13．06％～22．73％；蓝麦生物吸收比较大，为30．98％～39．81％。

The relativity and biological absorption ratio characteristic between wheat and its trace copper in the soil was studied ,taking Nanyang color wheat,Zhoumai 16 and Yanzhan 4110 as samples,rapidly determined by fixed -time and concentration direct -reading method.The result showed that the copper content was 2.17 ~7.81 μg/g in each sample of wheat flour,the highest total content of copper in blue wheat,the lowest total content of copper in Zhoumai 16.The copper content of wheat form Gongyi district was 4.599~7.808 μg/g,above other varieties of wheat background.The copper content was 2.17 ~4.52μg/g in wheat form Zhengzhou district,lower than that of the same wheat variety.The biological absorp-tion ratio of wheat was closely related to the varieties and the characteristics of the soil.The biological ab-sorption ratio of Zhoumai 16 was relatively low as 13.06% ~22.73%,while that of blue wheat was rela-tively high as 30.98% ~39.81%.
