摘 要:为探索新型尿素对小麦产量和氮肥利用率的影响,在石家庄市藁城区马庄村试验站进行了大田试验,以不施氮肥以及施用普通尿素、普通尿素+硫酸锌、普通尿素+硫酸锰为对照,研究了施用控失尿素、含锌尿素和含锰尿素对小麦产量及氮肥利用率的影响。结果表明:施用新型尿素可不同程度地增加小麦产量,除含锰尿素处理的产量显著高于普通尿素处理外,其他新型尿素处理的产量与各施氮对照相比差异均不显著。控失尿素处理较普通尿素处理能显著提高小麦氮肥利用率,指标增幅达20.2%;其他新型尿素的氮肥利用率与各施氮对照相比差异均不显著。3种新型尿素处理的小麦单位面积穗数、穗粒数、千粒重和氮素吸收量与各施氮对照相比差异均不显著。综合分析认为,施用含锰尿素对提高小麦产量效果最好,施用控失尿素对提高小麦氮肥利用率效果最好。In order to study the effects of new types of urea on the yield and nitrogen use efficiency of wheat,the field experiment was carried out at experiment station in Mazhuang Village,Gaocheng District of Shijiazhuang,the effects of slowly release urea,zinc urea and manganese urea on the yield and nitrogen use efficiency of wheat were studied,using no nitrogen,normal urea,normal urea with zinc sulfate,and normal urea with manganese sulfate as controls.The results showed that the application of new types of urea increased wheat yield in varying degrees.Except for the yield of manganese urea was significantly different from normal urea check,other new types urea were not significantly difference from all nitrogen checks.Compared with normal urea treatment,the slowly release urea treatment significantly increased the nitrogen use efficiency of wheat,and the index increased by 20.2%.The nitrogen use efficiency of other new types ureas were not significantly different from the all nitrogen checks.The ear number per unit area,grain number,grain weight and nitrogen absorption of above three new type ureas were not significantly different from the nitrogen checks.The comprehensive analysis showed that the application of manganese urea was the most helpful to improve the wheat yield,the application of slowly release urea was the most helpful to nitrogen use effeiciency of wheat.
关 键 词:控失尿素 含锰尿素 含锌尿素 小麦 产量 氮肥利用率
