摘  要：
研究了氮肥不同基追比和种类对玉米产量和氮肥利用率的影响。结果表明:33.3%普通尿素基施+33.3%大喇叭口期追施+33.3%抽雄期追施处理表现最佳,产量最高,达8 668kg/hm2。氮素用量减至80%的控释尿素基施处理和控释BB肥基施处理产量分别为8390kg/hm2和8 512kg/hm2,控释BB肥基施处理产量高于控释尿素基施处理,与33.3%普通尿素基施+33.3%大喇叭口期追施+33.3%抽雄期追施处理产量均没有达到1%极显著水平。在施用普通尿素的各个处理中,33.3%基施+33.3%大喇叭口期追施+33.3%抽雄期追施处理的氮肥利用率最高,为39.1%,可见适当的施肥方式能提高氮肥的利用率。控释尿素基施处理和控释BB肥基施处理的氮肥利用率分别为46.8%和49.5%,均高于施用普通尿素的各个处理,控释BB肥基施处理的氮肥利用率高于控释尿素基施处理。

摘  要：
The experiment of different ratio of base N to dressed N and type of nitrogen fertilizer on maize yield and nitrogen use efficiency was conducted.The results showed that the best treatment was N33.3%+N33.3%+N33.3%(N33.3% as basal and N33.3% top-dressed,and N33.3% green up-dressed)with the maize yield reached to 8668 kg/ha,the second maize yield was 8512 kg/ha with BB fertilizer,the third maize yield was 8390 kg/ha of controlled-release urea.There's no significant difference among the three treatments.Nitrogen use efficiency of BB fertilizer and controlled-release urea were better than N33.3%+ N33.3%+N33.3%.Nitrogen use efficiency of N33.3%+N33.3%+N33.3% was the highest among treatments of base to dressing ratio of nitrogen fertilizer.
