| 摘 要： | 通过盆栽试验研究了不同用量污泥对石灰性生土和熟土有机质和全氮、全磷、全钾含量的影响。结果表明：施用1．25％、2．5％、3．75％、5％的污泥，两种石灰性土壤有机质和全N、全P含量都显著高于对照，且随着用量的增大，增加幅度增大；而全K含量增加不显著。因此，合理利用污泥能提高土壤肥力。

| Abstract: | A pot experiment was conducted to study the effects of different application dosage of sewage sludge on the contents of organic matter, total N, total P, and total K in calcareous immature soil and Calcareous mellowsoil.The results indicated that application 1.25%, 2.5%, 3.75%, and 5% of sewage sludge all significantly increased the contents of organic matter, total N and total P in the two soils, and the increases of soil organic matter, total N and total P became bigger as the application dosage of sewage... |
