| 摘 要： | 通过盆栽试验,研究了2种改性剂(有机肥和无机功能材料)对重金属Cd、Pb和Cu污染土壤油菜生长及其吸收重金属的影响。结果表明,2种改性剂均可明显增加油菜产量,但对土壤的改良效果存在差别。有机肥对油菜茎叶吸收Pb具有较好的抑制作用,但却提高了土壤中有效态Cd、Cu含量,使油菜体内Cd、Cu含量增加;施加无机功能材料与有机肥相比,降低了油菜茎叶中Cd、Pb和Cu含量,对油菜吸收Cd、Pb和Cu均起到了较好的抑制作用。 |

| Abstract: | Pot experiments were conducted to study the effects of two modifiers(organic manure and functionalized monolayer material) on cole growth and its accumulation of heavy metals in soil polluted by Cd,Pb and Cu.The results showed that the two modifiers both increased the cole yield significantly,but there were differences in soil amelioration effects between them.Organic manure had better inhibition effects on absorption of Pb in the aboveground parts of cole plant,while it increased available contents of Cd and Cu in soil and made the contents of Cd and Cu in cole plant increase.Contrasted with organic manure,functionalized monolayer material decreased the contents of Cd,Pb and Cu in the aboveground parts of cole plant,and had better inhibition effects on absorption of Cd,Pb and Cu in cole. |
