摘要
为探究再生稻的研究现状、热点和未来发展趋势,以中国知网(China National Knowledge Infrastructure,CNKI)和科学引文索引(Web of Science,WoS)核心合集的文献资料为数据源,利用CiteSpace知识图谱分析工具,从年发文量、作者群体、发文机构、关键词聚类及突现等方面进行可视化分析。结果表明:近几年再生稻的相关研究正处于快速发展阶段,我国在该领域的研究具有重要的国际影响力,发文量位居第一,且以华中农业大学为首。国内期刊发文量最高的机构为湖南农业大学,但作者之间的合作不够紧密,呈独立的小分队。关键词聚类分析和突现词分析结果表明,再生稻产量一直是国内外学者研究的重点,以往主要以栽培方式、肥料施用为提高产量的手段。近年来,再生稻种植模式的温室气体排放、留茬高度、品质及遗传等成为关注的焦点,此方面研究可能会持续一段时间。
In order to explore the research status,hot spots and future development trends of ratoon rice,using the literature materials from the core collections of China National Knowledge Infrastructure(CNKI)and the Web of Science(WoS)as data sources,and using the CiteSpace knowledge map analysis tool,visual analysis was carried out in terms of annual publi-cation volume,author group,publication organization,keyword clustering and emergence.The results showed that research related to ratoon rice was in a stage of rapid development in recent years,and China’s research in this field has important international influence,ranking first in the number of papers published,led by Huazhong Agricultural University.The insti-tution with the highest volume of publications in China is Hunan Agricultural University,but the cooperation between the authors is not close enough and forms an independent team.The results of keyword cluster analysis and emergent word a-nalysis show that the yield of ratoon rice has always been the focus of research by scholars at home and abroad.In the past,cultivation methods and fertilizer application were mainly used as means to improve yield.In recent years,greenhouse gas emissions,stubble height,quality and inheritance of ratoon rice planting models have become the focus of attention,and re-search in this area may continue for some time.
