玉米种植密度与产量研究现状与趋势
Research Status and Trend of Maize Planting Density and Yield
摘要
Abstract
To have a comprehensive and in-depth understanding of the current situation and development trend of researches on maize planting density and yield at home and abroad,5150 pieces of literature on maize planting density and yield collected from the CNKI database and Web of Science Core Collection database from 2000 to 2022 were taken as samples for visual analysis based on CiteSpace software.The results showed that the United States ranked first in the total research volume in this field,followed by China,far beyond other countries.In recent years,China had overtaken the United States in the number of research papers in this field,and kept more than 100 articles published every year.Agronomy Journal had the largest number of publications,with a total of 230 papers,and had the largest influence in academic circles.Chinese scholar Liu Peng published the most papers,made the greatest contribution to the research progress in this field,and cooperated closely with other authors.The research institutions were mainly universities,mostly in northern China,and the cooperation among regional institutions needed to be strengthened.In this field,special corn such as fresh food and silage corn,water and nitrogen utilization efficiency,sustainable agriculture,mechanized management,soil properties,yield loss,mathematical model,straw utilization,and so on are the hot research issues in recent years.关键词
