Abstract本文分析比较了几种施肥制度下紫色土土体NO3--N,在降雨条件下土壤NO3--N含量累积和剖面分配特征,结果表明:夏玉米种植前后土体整个剖面中不施肥处理土壤NO3--累积量为-7.84 mg·kg_-1,呈亏损状态,其它三个处理累积量分别为:纯化肥52.67 mg·kg_-1、猪粪+化肥42.37 mg·kg-1、纯猪粪37.97mg·kg_-1;施肥改变了土体NO_3--N含量,增强了淋溶的可能性,其淋溶趋势为: 纯化肥>纯猪类> 猪类十化肥> 以区, 表明有机肥猪粪的合理施用对土体NO_3--N 渗漏淋失有一定固持作用。并指出纯化肥尿素处理下夏玉米季作物生长后期下层土体(30-80cm)其土壤NO_3--N 进一步向下迁移污染地下水的可能。
