基于知识图谱分析国内柿子研究进展与展望

Knowledge Mapping Analysis of the Research Progress of the Persimmon Industry in China

柿树是我国特色的经济栽培果树。为深入了解国内柿子研究方向及热点,梳理柿子研究历史进程和未来柿子领域发展前景,以2003—2022年中国知网数据库(CNKI)中文社会科学引文索引(Chinese Social Sciences Citation Index,CSSCI)和北大中文核心期刊论文作为研究对象,借助CiteSpace软件,对国内柿子相关研究文献的发文量、作者、发文机构、高频关键词等信息进行知识图谱的可视化分析。2003—2022年关于柿子的研究发文量年均42篇,呈现先增长后减少的趋势,发文数量虽有减少,但论文成果质量更高、更有影响力;西北农林科技大学、华中农业大学和中国林业科学院跻身发文量机构排名前三,并且形成一批稳健的研究队伍,为国内柿子领域研究做出巨大贡献。2003—2007年研究者对柿子的研究主要涉及柿树种植栽培、病虫防治、遗传育种等内容;2007—2011年,柿品种优化、采后处理运输、贮藏加工等研究内容居多;2012年至今,研究主要集中在柿子保鲜贮藏技术、品质提升、产品深加工等。利用知识图谱挖掘出柿子领域研究的最新现状和进展,为柿子课题研究提供参考和借鉴。

Persimmon is a characteristic economically cultivated fruit tree in China.To gain an in-depth understanding of domestic persimmon research directions and hotspots and to determine the historical progress of persimmon research and prospects for persimmon field development.In this study,we selected the Chinese Social Sciences Citation Index(CSSCI)and Peking University core journal papers from 2003-2022 in the Chinese National Knowledge Infrastructure(CNKI)as the research objects and visualized and analyzed the knowledge graph of domestic persimmon-related research literature in terms of publication volume,authors,publication institutions,and high-frequency keywords with the help of CiteSpace software.The average number of articles published on persimmon from 2003 to 2022 was 42 per year,with a trend of increasing at first and then decreasing.Although the number of articles decreased,the quality of the papers was higher and more influential.Northwest A&F University,Huazhong Agricultural University,and the Chinese Academy of Forestry rank among the top three in terms of volume of publications and have formed a stable team of researchers,making great contributions to the domestic persimmon research;in the last two decades,comprehensive and in-depth Chinese persimmon research has been conducted.In 2003-2007,research on persimmon was mainly related to cultivation,pest control,genetic breeding,etc.From 2007 to 2011,research on persimmon variety optimization,postharvest handling,transportation,storage,and processing was the most popular.From 2012 to the present,more research has been conducted on persimmon preservation and storage,quality improvement,and deep processing.The latest status and progress of research in the field of persimmon were mined using a knowledge graph to provide a reference and reference for persimmon subject research.
