摘　　要：以玉米杂交种郑单958为供试材料,采用裂区试验设计,以耕作方式为主区,氮素类型为副区,研究耕作方式与氮肥类型对夏玉米产量及氮素利用的影响。结果表明,深松与控释尿素结合可显著提高叶片含氮量和光合速率,以及花后夏玉米的氮素转运量和向籽粒的转运效率,为夏玉米高产奠定基础。Maize hybrid Zhengdan 958 was used as experimental material and split plot design was adopted with the farming method as the main area,the nitrogen type as the sub-area to study the effects of tillage methods and nitrogen fertilizer types on summer maize yield and nitrogen utilization.The results showed that the combination of subsoiling and controlled-release urea significantly increased leaf nitrogen content and photosynthetic rate,as well as nitrogen transport and transport efficiency to grain of summer maize after anthesis,laying a foundation for high yield of summer maize.
