针对水稻氮肥过量施用和移栽密度过低的问题，研究减氮增密对水稻产量与氮素利用效率的影响，以期为东北寒区水稻生产提供科学依据。于2019—2020年在吉林省前郭县红光农场进行田间试验，共设4个处理，分别为不施氮肥+移栽密度1.80×105穴·hm-2(N0）、传统施氮（氮肥用量235 kg·hm-2）+移栽密度1.80×105穴·hm-2(FP）、较传统施氮减量20%（氮肥用量188 kg·hm-2）+移栽密度2.40×105穴·hm-2（SNHD1）、较传统施氮减量20%（氮肥用量188 kg·hm-2）+移栽密度3.00×105穴·hm-2(SNHD2）。对水稻产量、地上部干物质积累与分配、氮素积累与分配以及氮素利用效率进行测定分析。结果表明：SNHD1和SNHD2处理相较于FP处理显著增加...
