摘　　要：为探究尿素中添加不同量的腐殖酸对农作物产量和氮素利用率的影响,以冬小麦为试验对象,以施用普通尿素和不施氮肥处理为对照,与施含腐殖酸尿素的处理进行比对,开展了田间小区试验。结果表明:施氮肥处理的冬小麦增产效果较好,与不施氮肥处理的相比差异达极显著水平,但各施氮肥处理间无显著性差异;与施用普通尿素处理相比,施用含腐殖酸尿素的处理均降低了土壤中硝态氮的含量,且硝态氮含量变化趋势基本一致;与施用普通尿素处理相比,施用含腐殖酸尿素的处理对冬小麦的增产效果并不明显,可能是因为腐殖酸添加量过少、施用时间较短。To investigate the effects of adding different amounts of humic acid to urea on crop yield and nitrogen use efficiency, a field plot trial is conducted with winter wheat as the test object, using the treatments with regular urea and no nitrogen fertilizer as controls, and comparing with the treatments with urea containing humic acid. The results show that the winter wheat yield is increased by the nitrogen fertilizer treatment, and the difference is highly significant compared with that without nitrogen fertilizer treatment, but there is no significant difference among the nitrogen fertilizer treatments. The nitrate nitrogen content in the soil is reduced in the treatment with urea containing humic acid compared with that with regular urea treatment, and the trend of nitrate nitrogen content is basically the same. The yield increase of winter wheat in the treatment with urea containing humic acid is not significant compared with that in the treatment with regular urea, probably because the amount of humic acid added is too small and the application time is short.
