摘　　要：研究聚脲甲醛缓释肥不同施用量对华北潮土小麦关键生理指标和氮肥利用率的影响。结果表明:相比单施尿素处理,单施聚脲甲醛处理的小麦产值、肥料总收益和肥料产投比各项指标均相对较低,但聚脲甲醛配施适量尿素(尤其50%聚脲甲醛氮+50%尿素),其小麦产值和肥料总收益指标明显提升,即聚脲甲醛配施适量尿素不仅可以维持作物的产量,而且可以显著提升作物的氮肥利用率和农学效率。The effects of different application rates of polyurea formaldehyde slow-release fertilizer on the key physiological indicators and nitrogen utilization efficiency of the fluvo-aquic soil wheat in North China are discussed.The results show that:Compared with single application of urea,the indicators(output value of wheat,total fertilizer income and fertilizer input ratio)of polyurea formaldehyde treatment are relatively lower,but the wheat output value and total fertilizer yield indicators have been improved with the treatment applying polyurea formaldehyde combined with appropriate amount of urea(50%polyurea formaldehyde nitrogen+50%urea nitrogen).Polyurea formaldehyde combined with appropriate amounts of urea can not only maintain crop yields,but also significantly increase crop yields,nitrogen utilization efficiency and agronomic efficiency.
