    Correlation Analysis of Cadmium Content in Six Crops and the Soil Cadmium Content in a County of Fujian Province

    • 摘要: 通过对福建某县常见6种作物镉含量和土壤镉含量的检测,分析不同作物镉含量与土壤镉含量的相关性。结果表明:6种作物对镉的富集能力差异较大,不同作物对土壤镉富集能力大小为芋头>水稻>茶叶>金桔>蜜柚>脐橙。6种作物与土壤镉相关性分析结果表明,芋头、茶叶、水稻镉含量与土壤镉含量呈显著正相关,金桔镉含量与土壤镉含量呈显著负相关,蜜柚、脐橙镉含量与土壤镉含量相关性不显著。因此,土壤镉污染区或处于镉污染临界值的耕地应避免种植芋头、茶叶、水稻这类与土壤镉相关性强的作物,可种植脐橙、蜜柚、金桔类的作物,从而减少农作物体内镉的富集,实现耕地的安全利用,确保农产品的安全。

       

      Abstract: Through the detection of cadmium content in 6 common crops and the soil cadmium content in a county of Fujian province, the correlation between the cadmium content in different crops and the cadmium content in soil was analyzed. The results showed that the enrichment capacity of six crops to cadmium was different. The enrichment capacity of different crops to soil cadmium was taro>rice>tea>kumquat>honey pomelo>navel orange. The results of the correlation analysis between six crops and soil cadmium showed that the cadmium content of taro, tea and rice was significantly positively correlated with the soil cadmium content, and the cadmium content of kumquat was significantly negatively correlated with the soil cadmium content, while the cadmium content of honey pomelo and navel orange was not significantly correlated with the soil cadmium content. Therefore, the crops with strong correlation with soil cadmium such as taro, tea and rice should be avoided being planted in the soil cadmium polluted area or the cultivated land at the critical value of cadmium pollution, while the navel orange, honey pomelo and kumquat could be planted, so as to reduce the accumulation of cadmium in crops, realize the safe utilization of cultivated land, and ensure the safety of agricultural products.
