Abstract:

The integration of water and fertilizer has been developed rapidly in the field of agricultural fertilization in recent years, which is an important way to improve crop fertilizer efficiency. Bibliometrics method was used to analyze the literature related to the integration of water and fertilizer. Based on the China National Knowledge Infrastructur (CNKI) database, literature related to integration of water and fertilizer from 2010 to 2023 was collected as the research object, while the number of literature, age distribution, journal distribution, publication institution distribution, author information, research content and hot topics in the core database of CNKI were objectively and systematically analyzed. The results showed that from 2010 to 2023, a total of 216 articles related to the integration of water and fertilizer were published in China. The earliest literature on the integration of water and fertilizer was published in 2010, and the number of published articles fluctuated with the increase of years. In terms of published papers, authors, publishing institutions, etc., papers on integration of water and fertilizer were mainly published in agriculture and forestry and other related professional journals. The publishing institution was focused on institutions of higher learning and research institutes in Beijing, Shandong and Ningxia, which had strong water and fertilizer research strength and academic background. At present, the core authors in the field of integrated water and fertilizer had not formed a stable group and the number of personnel was relatively small. According to the research content, water and fertilizer integration technology focused on the output, internet of things, control system and drip irrigation. The results objectively reflected the domestic research trends of integration of water and fertilizer from 2010 to 2023, which provided supporting data for researchers in this field.

Key words: integrated water and fertilizer, bibliometrics, CNKI, publication trend, research hotspots
