| 摘 要： | 通过对城市污泥及其堆制的有机肥田间对比试验,探讨了城市污泥及其堆肥对土壤农业化学性质的作用时效与作用后效。结果表明,施用城市污泥及其堆制的有机堆肥导致土壤的水解酸下降,盐基饱和度增加。城市污泥及其堆肥处理相应提高了土壤速效磷的含量2.9～7.9倍和3.1～6.5倍。在作用后效方面,水解酸随着施入的有机肥剂量增加而降低。城市污泥及其堆肥在作用后效方面与上年相比,盐基饱和度相应降低了21%～33%和12%～13%,土壤中速效磷含量增加10%～26%,对于有机堆肥,土壤中速效磷含量降低了16%～32%。 |

| Abstract: | The application of municipal sewage sludge and its compost on soil caused the decreasing of hydrolyzing acid content and the increasing of base saturation degree in the soil. The contents of soil available phosphorus in the soil applied by sewage sludge and its compost were increased 2.9-7.9 times and 3.1-6.5 times,respectively. On aftereffects,hydrolyzing acid declined with the increasing of organic fertilizers. After the application of sewage sludge and its compost,the base saturation degree of soil decli... |
