摘　　要：在食品安全领域,重金属污染已经对人类的健康造成了严重的威胁。以小白菜和薄层黑土为研究对象,通过盆栽试验,分别模拟被镉和铅污染的土壤,通过施入不同类型的化肥,研究被镉、铅污染的薄层黑土中,化肥对镉、铅活性及日常生活中食用的小白菜生长的影响。结果表明:在镉、铅污染的土壤中,不同施肥处理对土壤中镉、铅存在形态所占比例的影响不同;不同施肥处理对小白菜地上部鲜重、干重及叶长的影响不同,其中硝酸钙、骨粉和硝酸钾处理的小白菜上述3项指标值相对较高,而在氯化铵、普钙和氯化钾处理中,上述3项指标值则相对较低;不同施肥处理对小白菜对镉、铅的吸收量影响不同。In the area of food security, heavy metal pollution has posed a severe threat of people＇s health. The test simulated the soil which contaminated by cadmium and lead through pot experiment to investigated the effects of different kinds of fertilizers on the activity of cadmium, lead and pakchoi growth in the black thin-layer soil. The results showed that：different treatments of fertilizers had different impact on the proportion of form of cadmium and lead in soil; Different treatments of fertilizers had different effect on the shoot fresh weight, dry weight and leaf length of pakchoi. The three indexes above showed a relatively high values when pakchoi was treated with calcium nitrate,potassium nitrate and bone meal. But when pakchoi treated with ammonium chloride, superphosphate and potassium chloride, the values of three indexes were relatively low; the absorption amounts of pakchoi to cadmium and lead were various by different treatments of fertilizers.
