| 中文摘要: |
| 通过连续和间歇一维垂直入渗试验，研究了波涌灌灌施尿素下铵态氮和硝态氮在土壤和地下水中的迁移转化特性，表明波涌灌间歇入渗较连续入渗有保肥和减小地下水污染等优点，可以有效缓解农业施肥带来的地下水环境污染。该研究成果为进一步研究波涌灌溉水氮运移特性和波涌灌溉对地下水环境的影响奠定基础。 |
| 英文摘要: |
| The transforming characteristics of NH4+ and NO3- in soil and groundwater were analyzed through continuous and intermittent one dimensional vertical infiltration test under surge fertigation with urea. The results showed that intermittent infiltration was superior to continuous infiltration in retaining fertilizer and it could relieve the pollution of groundwater caused by agricultural fertilization. The research results laid foundatio
n for further study of the transforming characteristics of water and urea and the environmental effects of groundwater under surge irrigation. |
