土壤改良剂不给作物提供养分,但可以改善土壤性质,促进作物吸收养分.收集2000-2023年发表在Web of Science数据库核心合集的9 360篇文献,采用CiteSpace软件作为分析工具,简述全球土壤改良剂发文情况,开展关键词聚类分析,展望全球重点研究方向.结果表明,我国在土壤改良剂方面有着强大的科研能力和影响力,发文量远超其他国家.全球土壤改良剂研究的发文量增长迅速,研究范畴越来越广泛.未来,要充分利用工农业废弃物,研发新型土壤改良剂,混合施用多种改良剂,从而有效改善土壤性质,促进农业生产.
Research Progress on Global Soil Amendments Based on CiteSpace Software
Soil amendments do not provide nutrients to crops,but can improve soil properties and promote crop nutrient absorption.The 9 360 articles published in the core collection of Web of Science database from 2000 to 2023 are collected,the CiteSpace software is used as the analysis tool,the global publication status of soil amendments is briefly described,the keyword clustering analysis is conducted,and the global key research directions are looked forward.The results indicate that China has strong scientific research capabilities and influence in the field of soil amendments,with a much higher number of publications than other countries.The publication volume of global soil amendment research is growing rapidly,and the research scope is becoming increasingly broad.In the future,it is necessary to fully utilize industrial and agricultural waste,develop new soil amendments,and mix multiple amendments for application,thus effectively improving soil properties and promoting agricultural production.
