| 中文摘要: |
| 研究再生水灌溉条件下氮素在土壤中的转移规律，对于最大限度地利用再生水、减少水体污染具有重
要意义。研究表明，土壤中氮素的含量随再生水中氮素含量和灌溉量的增加而升高，在再生水灌溉条件下，土壤中铵
态氮浓度随着深度的增加而出现减小的趋势，而硝态氮和总氮随着深度的增加则出现了先增加后减小的趋势，并且
在70 cm 处出现了最大值。 |
| 英文摘要: |
| It is important to study the regeneration of nitrogen in the soil irrigated by reclaimed water, which can
maximize the use of recycled water and reduce water pollution. In this paper, through literature survey and test, we find
that the nitrogen content in the soil increases with the regeneration of the nitrogen content in water and irrigation amount in
reclaimed water increasing, the concentration of ammonium nitrogen in the soil decreases as the depth increasing, while
nitrate and total nitrogen increase and then decreasing, and reach the maximum at 70 cm layer. |
