Abstract: In order to objectively analyze the research status of peanut (Arachis hypogaea L.) heavy metals at home and abroad, summarize the key points and weaknesses of research at this stage, and provide data reference for peanut heavy metals researchers and decision makers, so as to promote the development of peanut high-quality and safe production. Based on Bibliometrics and CiteSpace V analysis, this paper makes an in-depth quantitative comparison and analysis of the number, age distribution, country, author information, publications, research contents and hot spots of peanut heavy metals by searching peanut heavy metals in English Web of Science database and Chinese CNKI database. The results showed that the earliest literatures on peanut heavy metals were published in 1978, and the research papers on peanut heavy metals showed a significant upward trend in the 40 years from 1987 to 2018, especially after 2006, which was the rapid development stage of peanut heavy metals research. Based on Bibliometric analysis, peanut shells, adsorption, removal and metallothioglobulin are the key words in the field of heavy metals research in peanut. From 2013 to now, stabilization, biochar, phytoremediation and other emerging hot spots have emerged. The research on heavy metals in peanut mainly focuses on two aspects: one is the effect of heavy metals on peanut physiology and growth; the other is the study on raw materials of heavy metal adsorbents from peanut hulls. China has a significant advantage in the research of peanut heavy metals, but the frequency of citation needs to be improved. Agricultural and forestry universities and scientific research institutions account for half of the publishing institutions, mainly concentrated in large provinces with strong agricultural and academic strength in China, such as Shandong Province and Guangdong Province. After years of development, the author group of peanut heavy metals research has taken shape, but the aggregation of high-yielding and active author group is not enough, the number of core authors and the quality of papers need to be improved, and international cooperation is an effective way to improve the output level of scientific research results.
