基于CiteSpace可视化分析有机肥料研究进展

从Wo S数据库核心合集中检索出1900—2019年相关文献4473篇,运用CiteSpace知识图谱分析工具,对合著国家、机构、作者、学科领域、关键词、文献共被引网络等进行可视化分析,对有机肥料的研究进展及演变趋势进行图谱解读与分析:①有机肥料对改善土壤理化性状、抑制土传病害、提高作物产量品质的作用及其机理依然是研究重点;②最新的基因测序等分子生物学技术在有机肥料研究中将得到更加广泛应用;③添加天然沸石、生物质炭等物质制造有机类肥料是未来有机肥料加工的重要方向;④有机肥料研究具有很强的学科交叉性,涉及农业、化学、环境生态学、环境科学、工程学等众多学科领域;⑤中国有机肥料研究发展迅速,国际上合作发表有机肥料学术论文数量前三的研究机构分别是中国科学院、南京农业大学、中国农科院,具有重要的学术影响力。

Visualization Analysis of Research Progress in Organic Fertilizer Study Based on CiteSpace

From the core collection of WoS database, 4 473 related papers published from 1900 to 2019 were retrieved, the co-cited countries, institutions, authors, discipline fields, keywords, literature cited networks, and the research progress and evolution trend of organic fertilizer study were visually analyzed based on the CiteSpace knowledge map analysis tool. The results showed that: 1) The effects of organic fertilizers on improving soil physical and chemical properties, inhibiting soil-borne diseases, improving crop yield and quality, and their mechanisms are still the focuses for research; 2) The latest molecular biology techniques such as gene sequencing will be used more widely in organic fertilizer research; 3) Adding natural zeolite, biochar and other substances to produce organic fertilizers is an important direction for organic fertilizer processing in the future; 4) Organic fertilizer research is an interdisciplinary, involving many fields such as agriculture, chemistry, environmental ecology, environmental science, and engineering; 5) The research on organic fertilizer in China is developing rapidly. The top three research institutions that jointly publishing academic papers on organic fertilizers in the world are Chinese Academy of Sciences, Nanjing Agricultural University, and Chinese Academy of Agricultural Sciences, and they have important academic influences.
