Abstract

With sewage irrigation development,effects of sewage irrigation in soil and groundwater are attentively.The experiment discusses effect of sewage irrigation on NO-3—N and NH+4—N of soil and groundwater in different groundwater depth,the experimental results indicate eluviation depth of NO-3—N is obviously correlation with groundwater level and irrigation water.The same level of irrigation,the concentration of NO-3—N of groundwater increase 33.99%,15.49%,7.50% in 2,3,4 m of groundwater level.
