| 摘 要： | 在脱水污泥施用量为栽培基质的0,10%,20%,40%,60%,80%和100%时,对油菜生长情况的影响进行了研究,同时研究了污泥的施用和油菜的种植对土壤中重金属含量的影响。结果表明:当污泥的施用量为80%～100%时,油菜无法生长;当污泥的施用量在10%～40%时,油菜获得了良好的生长响应,污泥的施用使土壤中重金属含量增加,但当污泥施用量为20%以下时,油菜的重金属含量是安全的,说明合理施用污泥,不会造成油菜重金属的污染;污泥的施用还增加了土壤中营养物质的含量,能够改良贫瘠土壤。 |

| Abstract: | The effects of various dewatered sludge loadings(0%,10%,20%,40%,60%,80% and 100%) on growth of rape were studied.The effects of sludge applying and rape planting on heavy metal contents in the soil were also studied.The results showed that the rape could not survive with 80%~100% sludge loading;when the loading was between 10%~40%,the rape exhibited a pronounced positive growth response.The sludge application caused increase of heavy metal concentrations in the soil,but the load-ing was under 20%,content co... |
