| 摘 要： | 通过田间试验研究了不同沼液灌溉量对土壤质量和生态安全的影响.结果表明在N、P、K养分相等条件下,完全沼液灌溉和与化肥配合施用均能改善土壤肥力,重金属等有害元素在国家土壤环境质量指标内,但沼液长期灌溉对土壤质量的影响还需进一步研究. |
| 关 键 词： | 沼液灌溉 土壤质量 |

| Abstract: | A 1-year field plot experiment was conducted to investigate the irrigation of sewage from marsh gas plant. The results showed that at the same dosages of N, P, K fertilizers both the treatment of sewage only and the treatment of sewage plus chemical fertilizers promoted soil fertility, and the concentrations of soil heavy metals were lower than the criteria of National Soil Quality Standards. However, the long-term effects of marsh gas sewage irrigation on soil quality should be concerned in the future. |
