| 摘 要： | 为使控释氮肥大面积推广应用,在黑龙江省黑土区对不同包膜材料的控释氮肥在玉米生产上的应用效果进行了研究。结果表明：各施用控释尿素处理,在株高、穗长、轴粗、百粒重和产量等指标上,均比施用普通尿素处理有不同程度增加,增产幅度为3.23%~8.33%。不同膜材料控释氮肥处理间产量差异不显著。

| Abstract: | In order to extend and apply controlled release urea,the effect of different coated materials controlled release urea on maize yield was conducted in black soil area in the middle of Heilongjiang province.The result showed that the controlled release urea reasonably could increase the maize yield apparently,and the range of increase was 3.23%～8.33%.The yield differences between different coated materials controlled release urea were not significant. |
