| 中文摘要: |
| 以玉米品种郑单538 为研究对象，通过田间试验，对陕西杨凌塿土地区经不同形态氮肥处理后玉米产
量、土壤全氮、土壤可溶性有机碳含量的变化情况进行研究，以阐明不同形态氮肥处理对玉米产量以及土壤质量的
影响，为关中平原玉米种植的合理施肥提供全面的理论依据。结果表明院施氮处理可以显著增加玉米产量。玉米生育
期内施氮处理的土壤中全氮、碱解氮含量显著高于不施氮处理。玉米生育期内不同形态氮肥处理的土壤可溶性有机
碳与不施氮的对照处理相比，无显著差异。施氮处理对于土壤微生物含量的影响不大。 |
| 英文摘要: |
| Taking Zhengdan 37 maize varieties as the research object, effects of different forms of nitrogen fertilizer on
maize yield, soil total nitrogen, and soil dissolved organic carbon content changes in Yangling, Shaanxi were studied
through field experiment, to provide comprehensive theoretical basis for the reasonable fertilization application for maize in
Guanzhong Plain. The results showed that the nitrogen treatments could significantly increase maize yield, increase the total
nitrogen and the nitrogen content in the soil, while had no significant effect on soil dissolved organic carbon, and had little
effect on soil microbial content. |
