| 摘 要： | 为了玉米增产促进农民增收，更加科学合理地施用氮肥减少对环境污染的危害，通过田间随机区组试验，研究了复混肥、缓释肥和复合肥3种氮肥对夏玉米产量及穗部性状的影响。结果表明，3种氮肥都能使夏玉米的产量、有效穗数和穗粒数显著提高；从纯收入和施肥效益水平上看，施用复合肥>复混肥>缓释肥，以施用复合肥效果最佳。 |

Effects on Yield and Ear Characteristics of Summer Maize in Different Nitrogen Fertilizers |
|
| Abstract: | In order to increase maize yield stimulative farmer is added close, more scientific and rational application of nitrogen to reduce the pollution to environment, through field randomized block experiment, studied the compound fertilizer, slow-release fertilizer and compound fertilizer of 3 kinds of nitrogen fertilizer on summer corn yield and panicle traits influence. The results showed that,3 kinds of nitrogen fertilizer can make the summer maize yield, effective panicle number, grain number per spike and significantly improve; from the net income and the efficiency of fertilization level, applying fertilizer, compound fertilizer, slow-release fertilizer, From the output and economic benefits compared to the best effect, application of compound fertilizers. |
| Keywords: | Summer Maize Nitrogen Fertilizer Yield Ear Characteristics |
