| 摘 要： | 通过采样调查，分析比较了江苏省海安县长期施用畜禽粪便稻田和施化肥稻田土壤氮素养分的剖面分布特征。结果表明：与邻近施化肥的稻田相比．长期施用畜禽粪便能显著提高土壤的全氮、碱解氮、硝态氮等苯分含量，土壤剖面中的氮素分布呈上高下低的分布特征，耕层养分富集现象较为严重。长期大量施用畜禽粪便在提高稻田土壤氮素水平的同时，累积在土壤剖面中的硝态氮呈明显向下淋失的趋势. |

| Abstract: | The profile distribution characteristics of the nitrogen in paddy soils were quantified by samples investigation after poultry manure long-time applied in Hai'an county,Jiangsu Province.The results showed that compared with chemical fertilized soil,there were significant increases of capacities of soil capacities of soil total nitrogen,hydrolysis-N and Nitrate-N by long-term poultry manure application.The level of nitrogen increased across the soil profile from the surface soil downwards after long-term pou... |
