摘　　要：本文利用太原市污泥和污泥堆肥分别作肥源进行了二年的盆栽试验和田间试验，结果表明：每公顷施污泥７５ｔ和污泥堆肥２４０ｔ时，土壤中的Ｃｕ、Ｐｂ，Ｃｄ、Ｎｉ等有害金属含量均未超过土壤的安全控制标准。随着污泥及污泥堆肥用量的增加，土壤中可供植物吸收的氮、磷、有机质等营养成分相应递增。污泥和污泥堆肥的施用不同程度的提高了土壤水分含量、田间持水量和阳离子代换量等，从而改善了土壤的物理性质。AbstractAfter two years pot experiment and field experiment with sewage sludge-and sludgee compost in Taiyuan as a manure resource, the soil sampleswere collected after the crops, being harvesed.The amount of the harmfulheavy metals the nutritional constituents and the physical propertie ofsoils( cation exchange capacity and porosity)were measured.After the soilswere manured at 75 t/ha sexyage sludge and 240 t/ia sludge compost,theamount of Pb,Cd Ni,Cr,etc. in soils did not exceed the safe controll-ing;stadards In addition,with the increase of manured sewage sludge andsludge compost, the amount of the nutritional constituent such as N,P,and organic matter increased correspondently,The water content, field moisture capacity and cation exchange capacity in soil alsoinereased. So the physical properties of soil can be improved
