为明确中国玉米优势产区生产格局变化和玉米施肥研究现状，以中国知网(CNKI)数据库、中国农村统计年鉴和2023年国家科学施肥指导意见为信息来源，对我国玉米生产与施肥研究的文献发表量、来源出版物、项目分布、研究机构、种植面积及肥料施用量进行整合分析。统计数据表明，2012-2022年，我国玉米种植面积整体呈上升趋势。2018-2021年东北平原地区玉米总产量最高，平均为11 560 kg/hm²。2012-2022年，全国玉米产量与施肥研究发表文献年均保持在700篇以上，2016年文献发表数量最多，为1 156篇。黄淮海区域累计发表相关文献最多，占全国发文量的16.7%，综合优势明显。

In order to clarify the change of production pattern in China's dominant maize producing areas and the current status of maize fertilization research, the China Knowledge Network(CNKI) database, China Rural Statistical Yearbook and the 2023 National Scientific Fertilization Guidelines as the information sources to integrate and analyze the amount of literature published, source publications, project distribution, research institutes, planting area, and fertilizer application in China's research on maize production and fertilization. Statistical data showed that the overall trend of maize planting area in China was upward from 2012 to 2022, the total maize yield in the Northeast Plain region was the highest in 2018-2021, with an average of 11 560 kg/ha. The published literature on maize production and fertilizer research in China remained above 700 articles per year from 2012 to 2022, with the highest number of literature publications was 1 156 in 2016. The Huang-Huai-Hai region had the most accumulated publications, accounting for 16.7% of the national publication volume, with obvious comprehensive advantages.
