摘  要:
地下水的硝态氮污染已广泛引起人们关注。农业生产中施用的氮肥随灌水或降水向下淋移是引起地下水中硝态氮含量增高的主要原因之一。从农业耕作措施、氮肥管理、水管理等田间管理措施对土壤硝态氮迁移的影响方面进行了综述,指出了研究中存在的问题与发展趋势。

摘  要:
Groundwater pollution by nitrate-nitrogen has caused extensive concern in worldwide. The downward transport of applied nitrogen-fertilizer in agricultural production through irrigation or rainfall is one of main reasons that NO3~--N was enriching in groundwater. The effects of management practices in farmland including tillage practices, nitrogen-fertilizer and water management on nitrate-nitrogen transport in soil were reviewed. The existing deficits and future trend on the research were indicated.
