为研究国内间作种植氮素利用的发展态势和热点，利用文献计量学方法和CiteSpace软件，以Web of Science(WoS)核心数据库以及中国知网(CNKI)的间作种植氮素利用研究相关文献为研究对象，对间作模式氮素利用领域2000-2022年的中文和英文文献的发文特点进行分析。从发文量看，文献整体呈逐年增加趋势，间作模式氮素研究的中文和英文发文差异较大，前10年以中文发文为主，近年来英文发文量已远超中文发文量，从来源期刊看，中文发文量最多的期刊以《植物营养与肥料学报》、《应用生态学报》、《中国生态农业学报》、《作物学报》、《中国农业科学》等国内知名期刊为主，英文发文最多的期刊以《Plant and Soil》、《Field Crops Research》等国外主流1区期刊为主，影响因子均在3。5分以上。从研究机构看，中文发文最多的机构为云南农业大学和四川农业大学，英文发文量主要贡献机构是中国农业大学和中国科学院。从研究侧重点和研究热点看，主要围绕产量、玉米、小麦、土壤、氮素及其利用效率开展，近年来研究热点出现一定的差异，英文论文注重土壤微生物以及氮与磷等养分相互作用等最前沿研究，中文论文研究热点仍是增产增效，侧重经济效益同时兼顾环境效益，在理论研究基础上更注重技术的落地应用。研究发现，中国虽然在该研究领域发文量和研究水平迅速提高，但中文发文相对减少，国内也缺少有影响力的英文主流期刊;研究机构与农户等从业人员的沟通交流机制存在问题，需要注重学术成果的转化应用。提出今后间作种植研究方向，开展多元化间作种植及其微生物和基因研究，推动配套农机设备的研发与应用，促进农田生物多样性、生态效应和农业可持续发展潜力。
Analysis of Characteristics of Research Papers on Nitrogen Utilization in Crop Intercropping Cultivation in China from 2000 to 2022
Clarifying the differences in the characteristics of Chinese and English articles on farmland intercropping can better provide theoretical support and reference for carrying out researches in the field,condensing results and publishing high-level articles under the new situation.In this study,CiteSpace software was used to conduct a bibliometric analysis of keyword co-occurrence and keyword burst to analyze the characteristics of Chinese and English literatures in the field of nitrogen utilization in intercropping system in 2000-2022,using the literatures related to nitrogen utilization in intercropping system in Web of Science(WOS)core database and China National Knowledge Infrastructure(CNKI)as the research objects.It was found that the Chinese and English publications of nitrogen research in intercropping system have been quite different.In the first decade,Chinese publications were mainly focused on the economic and environmental benefits of nitrogen regulation in intercropping system under different external conditions.However,in recent years,the number of English publications has far exceeded the number of Chinese publications,and many highly cited articles have been published in journals with great international influence.The journals with the largest number of articles in Chinese were mainly domestic well-known journals such as Journal of Plant Nutrition and Fertilizer,Chinese Journal of Applied Ecology,Chinese Journal of Eco-Agriculture,Acta Agronomica Sinica and Scientia Agricultura Sinica.The journals with the largest number of articles in English were mainly foreign mainstream journals such as Plant and Soil and Field Crops Research,and the impact factors were all above 3.5 points.The institutions with the most Chinese publications were mainly Yunnan Agricultural University and Sichuan Agricultural University.From the perspective of the number of English publications,China Agricultural University and the Chinese Academy of Sciences were the main contributors.Compared with the keywords published in Chinese and English journals,the research content has certain similarities,mainly focusing on yield,maize,wheat,soil,nitrogen and nitrogen utilization efficiency.However,in recent years,there have been some differences in research hotspots.The published English articles focused on microorganisms and nitrogen research at a large scale,while the published Chinese articles still focused on increasing production and efficiency,focusing on economic benefits while taking into account environmental benefits.On the basis of theoretical research,they paid more attention to the application of technology,which can be replicated and more operable.Although the number of articles published and the level of research in this field have increased rapidly in China,the number of Chinese articles has been relatively reduced,and there is a lack of influential English mainstream journals in China.In the future,we should pay more attention to the combination of theory and practice,establish professional Chinese journals or set up special sections,open up the boundary between Chinese and English articles,and serve the production practice.At the same time,diversified intercropping planting and its microbial and genetic research should be carried out,and the research and development and application of supporting agricultural machinery and equipment should be promoted to promote farmland biodiversity,ecological effects and agricultural sustainable development potential.
