为了解国光苹果河北优势产区怀涿盆地的土壤营养与环境质量情况，2015-2017年对该地区的9个规模性国光苹果园进行了不同土壤养分和重金属含量等指标的测定，采用土壤养分评价、单项与综合污染指数等方法，分析了苹果园土壤养分及土壤环境质量状况，最终进行分级和评价。结果表明，怀涿盆地国光苹果园土壤有机质含量总均值为37.25 g/kg，全氮、碱解氮、有效磷、速效钾含量总均值分别为1.62 g/kg、104.92 mg/kg、21.32 mg/kg和146.79 mg/kg，交换性钙、交换性镁、有效铁、有效锰、有效铜、有效锌、有效硼含量总均值为1 191.35、308.86、6.03、11.12、0.87、1.35、1.13 mg/kg，土壤养分含量评价为较高水平；同时，5种重金属均未超过国家重金属限量值，土壤环境质量综合评价为清洁等级。综上，怀涿盆地土壤质量水平完全符合发展优质国光苹果的要求。但也发现在个别监测点土壤中有效铁、铬和汞元素存在预警性风险，建议定期对土壤进行测定与评估，适时开展土壤修复工作。

In order to understand the soil nutrition and environmental quality of the advantageous Ralls apple production area of Huaizhuo basin,soil nutrition and heavy metal element content in 9 large-scale Ralls apple orchards of Huaizhuo basin were detected and analyzed,and the environmental quality of soil was evaluated by methods of soil nutrient evaluation,single pollution index and comprehensive pollution index in 2015—2017.Moreover,some classification and evaluation were given on the soil nutrient level and environmental quality status.The results showed that,the average of organic matter content in the apple orchard soils of Huaizhuo basin was 37.25 g/kg,the averages of total N,available N,available P,available K contents were 1.62 g/kg,104.92 mg/kg,21.32 mg/kg,146.79 mg/kg,respectively,and the averages of available Ca,available Mg,available Fe,available Mn,available Cu,available Zn,available B contents were 1 191.35,308.86,6.03,11.12,0.87,1.35,1.13 mg/kg,respectively,so the nutrient content was at higher level.At the meantime,the contents of heavy metals were lower than the limited requirements by the national standards, so the soil environment quality was evaluated to a level of cleanliness. In summary,the soil quality level in Huaizhuo basin was suitable for the development of high quality Ralls apple.However,the contents of Cr,Hg and available Fe in some monitoring points were approaching early warning risk.It is recommended to regularly determine the soil environmental quality and develop soil remediation measures.
