| 摘 要： | 目的]研究不同施肥措施对休宁土壤Cd形态的影响与蔬菜富集特性。方法]通过盆栽试验，研究了鸡粪、改良剂和外源Cd对体宁菜园土中重金属Cd形态的影响与蔬菜富集特性。结果]结果表明，施入鸡粪可降低土壤中可交换态Cd和铁锰氧化态Cd的含量，增加了土壤中的碳酸盐态Cd和有机物结合态Cd含量。改良剂可提高土壤中可交换态Cd和碳酸盐态Cd的含量。外源Cd进入到土壤中主要以可交换态、碳酸盐态和铁锰氧化物结合态存在。萝卜、白菜和辣椒的可食用部分对土壤Cd的富集能力为：白菜〉萝卜≈辣椒，转移系数为白菜〉萝卜〉辣椒。结论]在农业生产上，可在土壤中添加有机肥和无机改良剂减少蔬菜时重金属Cd的吸收积累。在重金属Cd含量高的土壤中应避免种植富集能力极强的蔬菜品种。 |
