摘　　要：[目的]分析黄河三角洲地区典型农田小麦NPK肥料的利用率。[方法]以冬小麦为研究对象,设置了5个处理:NPK、NP、PK、NK和缓释肥料,比较NPK平衡施肥和施用缓释肥2种施肥方式的差异。[结果]土壤中残存速效养分、小麦产量及生物产量存在显著差异(P<0.05)。NPK平衡施用有助于小麦增产,较NP、PK、NK处理分别提高了9.6%、11.3%、33.8%。同时NPK处理中N、P、K肥料利用率较缓释肥处理均有所增加。[结论]选择适宜的施肥模式是该地区提高肥料利用率的关键环节。[Objective]To analyze the utilization rates of NPK fertilizers in the wheat farmland of the Yellow River Delta.[Method]Five treatments were arranged in this study,i.e.,NPK,NP,PK,NK,and slow-released fertilizer.The differences in NPK utilization between balanced NPK fertilization and slow-released fertilizer fertilization were determined.[Result]The significant differences were observed in soil available nutrients contents,wheat biomass production and grain yield.Higher wheat grain yield were in the balanced NPK fertilization treatment,and the utilization rates of NPK fertilizers were greater than that in the slow-released fertilizer treatment.[Conclusion]Selecting the suitable fertilization mode could be the key step to increase the fertilizer utilization rate in the study area.
