Multidimensional Analysis of NHCMT Based on VOSviewer——From the Perspective of Evolution,Application,and Emerging Challenges
Non-hazardous Cultivation Management Technology(NHCMT)is an agricultural method that enhances crop safety,quality,and yield.It does so by scientifically managing the use and residue of toxic substances.As technology advances,NHCMT's applications have diversified.Macroscopic multidimensional analysis with VOS-viewer is now key in NHCMT research.This paper examines NHCMT's current research scope,focusing on its in-novative aspects and diversity.The CNKI database is used to retrieve relevant literature.A visual analysis tool as-sessed 237 papers,publication frequency,authorship,research hotspots,and emerging trends.The results show that:① the analysis shows a rising trend in NHCMT publications,particularly in crop cultivation,peaking in 2019 and 2020.② After retrieval and correction,a total of 190 pieces of metadata were used from 30 journals.③ The terms extracted from the above literature were further screened to exclude terms with general meaning.Of the 81 keywords,29 reached the threshold.These keywords are grouped into 7 different clusters,with the crop cultivation field showing great interest in the technology.Crop cultivation notably focuses on NHCMT.In response to societal demands,NHCMT has become a mainstream approach in China's crop cultivation.It has driven agricultural pro-gress,enhanced crop yield and quality,and reduced environmental impact.The paper delves into the concept of non-hazardous crops,challenges in NHCMT,and its practical application.Combining literature review,case analy-sis,and logical reasoning,and integrating both domestic and international findings,NHCMT's principles,features,benefits,limitations,and growth trends are comprehensively discussed.NHCMT's current usage and management in crop cultivation are also analyzed,which provides practical recommendations.
