摘　　要：为探求土壤Pb污染和潍县萝卜污染的相关性,为无公害潍县萝卜生产提供理论依据,以潍县萝卜为试验材料,采用温室盆栽土培的方法研究了土壤Pb浓度与潍县萝卜Pb污染的相关性,并对潍县萝卜生产要求的土壤Pb污染阈限值进行了预测。研究结果表明:低浓度Pb污染的土壤对潍县萝卜生长、产量无明显影响;随着施Pb浓度的增加,潍县萝卜中的Pb含量呈增加趋势,且与土壤中的Pb含量相关性显著;模拟得出的潍县萝卜Pb污染阈限值为(188.39±10.36)mg/kg。In order to determine the impact of soil Pb pollution on Weixian radish （Raphanus sativus L. ） and to provide the new theoretical basis for green vegetable production, the relationship between soil Pb content and Pb pollution of Weixian radish was studied under greenhouse conditions using Weixian radish in Weifang, Shandong Province. Soil Pb pollution threshold for the production of greenvegetable was analyzed as well. The results showed that low Pb polluted soils have insignificant effect on Weixian radish growth, and Pb content in Weixian radish increases with increasing density of soil Pb, and significant correlation exists between Pb content in the soil and Weixian radish. Simulated Weixian radish Pb pollution threshold is 188.39 ± 10.36 mg/kg.
