| 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. |
