| 摘 要： | 通过盆栽和大田试验，初步探讨了污泥复合肥种植小麦的肥效及其对小麦重金属吸收的影响。试验结果表明，污泥复合肥对小麦的增产效果和土壤的增肥效果明显优于化肥，等同于市售复合肥，它能促进植株生长发育，提高小麦产量，对土壤速效养分的积累有明显的促进作用；污泥复合肥处理的小麦籽粒中重金属Cu、Zn、Pb、Cd的含量均在国家食品卫生标准范围内。

| Abstract: | The amount of sewage sludge production is increasing with the raising of wastewater treatment in China,how to dispose it has been an urgent problem for government and wastewater treatment plants.Sewage sludge contains various kinds of pathogenic bacterium and heavy metals which may cause serious environmental pollution if without correctly disposed.However,sludge also contains various kinds of nutrients and organic matter,which are necessary for plant growth,and would be a resource if it were utilized for p... |
