【摘要】 采用原子吸收法测定了汉源县7个地点的金花梨果园土壤和果实中重金属元素Cu、Cd、Cr、Pb的含量。将测定结果与中华人民共和国农业行业标准中的相关标准值进行分析比较。结果表明:7个采样地点中土壤重金属元素Cu、Cd、Cr、Pb的含量均小于标准值,果实中只有2个地点的Cd元素含量略微高于国家标准值,分别为标准值上限的165.67%和160.33%。相关性分析则表明土壤和果实中重金属元素之间并没有太大的相关性。更多还原

【Abstract】 The content of heavy metals such as Cu,Cd,Cr,Pb in soil of seven orchards and in fruit of Jinhua pear in Hanyuan county were determined in this paper.The results showed that the content of Cu,Cd,Cr,Pb in orchard soil and fruit is lower compared to the agriculture industry standard of fresh pear and soil of P.R.C.The content of Cd in fruit of two sample locations was higher than the industry standard by 165.67% and 160.33%.The relativity of content of heavy metal in soil and fruit is not obvious.更多还原
