| 摘 要： | 采用温室盆栽试验,研究了在黑曲霉(30582)作用下油菜对潮褐土Cd、Zn复合污染胁迫的耐性及富集特征。结果表明:接入黑曲霉菌液对油菜地上部干重总体上无明显影响,且降低了油菜对土壤Cd、Zn的吸收量。加入黑曲霉菌液后,油菜地上部和地下部Cd含量较对照最高分别降低了31.60%,37.82%;地上部和地下部Zn含量较对照处理最高分别降低了35.12%,35.74%;土壤有效态Cd、Zn含量显著减少,较对照最高分别降低了30.51%,39.64%。综上,黑曲霉有效地降低了污染土壤中Cd、Zn的生物有效性,对土壤中低浓度重金属污染的原位固定表现出较佳的效果,具备应用于修复Cd、Zn污染土壤的潜力。

| Abstract: | A pot experiment was carried out investigate the effects of Aspergillus niger(30582) on the endurance and characteristics of Cd,Zn in soil when oilseed rape growing.The results showed that Aspergillus niger not only had no significant effect on the aboveground biomass,but also decreased the concentrations of Cd,Zn in oilseed rape.The concentrations of Cd in shoot and root of oilseed rape decreased by 31.60%,37.82% and Zn concentration in the shoot and root of plant were decreased by 35.12%,35.74% compared w... |
