| 摘 要： | 为筛选适合在中轻度镉污染土壤上有效降低芹菜吸收镉的改良剂,用模拟镉污染土壤进行盆栽试验,研究纳米羟基磷灰石(HA)、人造沸石(Z)、过磷酸钙(P)和石灰(L)的两两组合对芹菜生物量、镉吸收量、土壤pH值的影响.结果表明:与不施改良剂的污染对照相比,6种改良剂的配伍组合对芹菜生长均有显著的促进作用(P＜0.05)；在添加纳米羟基磷灰石(5 g/kg)+人造沸石(5 g/kg)和纳米羟基磷灰石(5 g/kg)+过磷酸钙(4 g/kg)后显著抑制芹菜对镉的吸收,芹菜可食部镉含量分别降低了57.43％和54.88％.综上,筛选出纳米羟基磷灰石(5 g/kg)+人造沸石(5 g/kg)和纳米羟基磷灰石(5 g/kg)+过磷酸钙(4 g/kg)的组合可以广泛应用在镉污染土壤的修复.

| Abstract: | In order to select the modifiers that can effectively reduce the absorption cadmium of celery on cadmium pollution soil,pot experiment was performed to study the effects of pairs of nano hydroxyapatite(HA),artificial zeolite(Z),superphosphate(P)and lime(L)on the celery biomass,cadmium uptake,soil pH value.The results showed that application of 6 kinds of modifiers combination could significantly improve the growth of celery,and the biomass of celery was significantly higher than that of the pollution contro... |
