摘　　要：本文利用数理统计方法分析降尘对棉花和玉米重金属含量的影响。结果表明:受降尘处理的棉花各器官铜素、铁素和锰素含量均大于不受降尘处理的各器官含量;受降尘处理的棉花叶片和根中的锌素含量均高于不受降尘处理的棉花。受降尘处理的玉米叶片铜素、铁素和锰素含量高于不受降尘处理的玉米叶片,而受降尘处理的玉米根系铜素和锰素含量低于不受降尘处理的玉米根系;各处理玉米各器官中的锌素含量存在差异,但是差异不显著。In this paper, the effects of falling dust on the heavy metal of cotton and maize by statistic method were studied. The result showed that the Cu, Fe and Mn content of surrender dust processing cotton organs were higher than that of no surrender; The zinc content in cotton leaves and roots of cotton with surrender dust were higher than that with no surrender dust. The Cu, Fe and Mn contents in maize leaf with surrender dust were higher than that of no surrender dust treatment; The Cu and Mn content in maize root with surrender dust treatment were lower than that of no surrender dust; The zinc contents in different organs of maize with different treatments had differences, but the differences were not significant.
