摘要/Abstract

摘要： 控制农业非点源对水体的污染是实现区域水质管理的必要组成部分。为此,设计了一系列水田、旱地田间试验和室内模拟实验。试验结果表明,渗漏水硝态氮污染与氮肥施用量呈正相关,同时通过统计处理获得农业非点源氮素污染负荷量,并提出了农业非点源氮素污染的几种有效的控制对策。

关键词: 农业非点源污染, 氮素比负荷量, 节水灌溉, ¹⁵N示踪法

Abstract: Field experiments and simulation tests show that the nitrate content in percolating water is positively correlated with the application rate of nitrogenous fertiIizers. The nitrogen specific load of agricultural non-point sources is obtained by statisticaltreatment, and the effective countermeasures for nitrogen pollution control from these sources are put forward.

Key words: Agricultural non-point sources pollution(ANPSP), Nitrogen specific loads(NSL), Saving-water irrigation, ¹⁵N-tracing technique
