Abstract:

【Objective】Clarify the research hotspots and development trends in the field of saline soil improvement domestically and internationally since the 21st century,to provide references for in-depth research on saline soil improvement.【Methods】Using the core collection of Web of Science (WOS) and CNKI databases as search objects,Excel 2007 software for drawing and CiteSpace software for knowledge graph analysis,the relevant literature was quantitatively and visually analyzed from five perspectives:annual publication volume,authors,publication institutions,keywords time co-occurrence analysis,and burst words analysis.【Results】The trend of domestic and international literature publication volume were:from 2003 to 2009 in slow growth stage,from 2010 to 2016 in fluctuating (significant) growth stage,and in rapid growth stage from 2017 to 2023. The main authors were YANG Jinsong,ZHAO Lanpo,YAO Rongjiang,SUN Zhaojun,WANG Quanjiu,KANG Yaohu,WAN Shuqin,QADIR M,GHEYI H R,MURTAZA G,et al. The main research institutions were Chinese Academy of Sciences,Egyptian Knowledge Bank,Indian Council of Agricultural Research,Spanish National Research Council,and U. S. Department of Agriculture. In terms of keywords analysis,the research hotspots were water and salt transport and the regulation mechanism,research on plant salt tolerance,the application of chemical amendments,green reduction of saline-alkali obstruction,and the biological and microbial remediation of saline-alkali obstruction. The main burst words were biochar,wet front,microbial community,plant biostimulant(PBs),plant growth-promoting rhizobacteria(PGPR),and salt-tolerant soil bacteria.【Conclusion】Currently,domestic and international research on saline soil improvement has entered the stage of rapid development. China and the United States were the global leaders. India and Australia were gradually strengthening their research capabilities. Domestic and international research were mainly focused on soil carbon sequestration,biochar,microbial community,antioxidant enzymes,Phosphate utilization,salt-tolerant soil bacteria,etc.,as well as soil nutrient movement,salt obstruction reduction,chemical amendments,microbial remediation and so on. In the future,salinization driving mechanism,plant growth-promoting rhizobacteria,microbial remediation of saline obstruction,and collaborative monitoring and analysis of big data technology may become research hotspots.
