摘　　要：为研究新型控失尿素和施用方法对小麦产量等影响，在安徽省皖北3个县开展了此项试验。小麦田采用一次性基施和基追结合的方式施用控失尿素和普通尿素，通过比较小麦最终产量，分析新型尿素对小麦产量、产量构成和氮肥利用率的影响。结果表明，不施肥处理小麦最终产量341．6kg／667m^2，施用化肥后增加产量37．9％．46．0％。控失尿素全部基施较普通尿素相比增产5．90％，氮肥农学利用率提高21．3％；控失尿素基追结合较普通尿素相比增产1．01％，氮肥农学利用率提高3，9％。试验证明，施用新型控失尿素能有效提高小麦产量，提高氮肥农学利用率．尤其是作为基肥一次性施用．效果更为明显．Experiments was conducted on three counties in north of the Anhui province to study of the impact of a new loss-control urea and application method on wheat yield. Loss-Control Urea and normal urea were base applied and base/topdressing applied on wheat. The impact on wheat yield, yield component and nitrogen utilization efficiency was analyzed by comparing final yield of wheat. The results indicated that wheat yield with no fertilizer treated was 341.6kg/667m2 and fertilizer application could promote it by 37.9%-46.0%. Yield and nitrogen agronomy efficiency of loss-control urea base applied wheat increased 5.90% and 21.3%, respectively, when comparing with normal urea treated wheat. Yield and nitrogen agronomy efficiency of loss-control urea base/topdressing applied wheat increased 1.01% and 3.9%, respectively, when comparing with normal urea treated wheat. It illustrated that the application of new loss-control urea could increase wheat yield and nitrogen agronomy efficiency. These advantages were promoted when new loss-control urea was base applied.
