| 摘 要： | 采用东南景天单种、东南景天与香芋套种对污泥进行植物处理,将植物处理后的污泥作为肥料与上层土壤混合后种植玉米,并设不同的肥料处理来研究对玉米生长的影响。结果表明,利用植物处理后的污泥作为肥料种植玉米,玉米生长良好,且长势和产量明显优于对照和施用化肥的处理,其中单种东南景天处理后的污泥与土壤混合种植的玉米籽粒的产量最高,分别是对照和化肥处理的3.26和2.66倍;利用植物处理后的污泥作为肥料所生产的玉米籽粒中Zn、Cd、Cu、Pb的含量符合国家饲料卫生安全标准,作为饲料是安全的。

| Abstract: | Agricultural application of municipal sewage sludge（MSS）had been being one of the most promising ways to dispose of MSS all over the world.Fresh MSS were treated by phyto-treatment system,including mono-Sedum alfredii,co-planting Sedum alfredii and Alocasia marorrhiza,then the treated MSS as fertilizer were mixed with the upper soil and maize was planted.The results showed that the growth of maize with application of treated MSS were better than those treated with chemical fertilizer and the contro（lno fertilizer）.The yield of grain in the treatment of MSS treated by mono-Sedum alfredii was the highest,which was 3.26 and 2.66 times greater than that of the control and the chemical fertilizer treatment.The concentration of Cu,Zn,Pb,Cd in grain of maize treated with MSS were below the tolerance limit of heavy metals according to the Chinese standards of feeds. |
