摘要：目的 揭示我国枸杞育种、种植、采收、加工、储存5个领域的研究现状及热点。方法 计算机检索中国知识资源总库（CNKI）2004年1月—2013年12月枸杞育种、种植、采收、加工、储存等领域相关文献，采用可视化统计软件CiteSpaceⅡ进行关键词分析，获取高频关键词、高频关键词共现网络和高频词聚类图。结果 共纳入文献759篇。枸杞育种方面高频关键词有“遗传多样性”“雄性不育”“its序列”“愈伤组织”“花药培养”等，种植方面高频关键词有“产量”“品质”“硬枝扦插”“灌水量”等，采收和加工方面高频关键词有“枸杞采摘机”“枸杞烘干窑”“热风干燥”“组合干燥”等，储存方面高频关键词有“农药残留”“重金属”“残留量”“有机磷农药”等。枸杞储存高频关键词共现网络表明研究热点为农药残留、重金属的检测以及鲜果的储存方面，而枸杞储存高频词共现聚类图则提示聚类规模依次为“包装”“保鲜”“枸杞多糖”等。结论 枸杞种植的研究热点主要侧重于影响枸杞产量和品质的栽种技术；在采收和加工领域，代替传统手工采摘的采摘机设计、研发已成为关注热点，现代热风干燥已基本取代传统的晒干或烘干手段；在储存方面，有关保鲜技术的研究已引起关注。

Abstract： Objective To discuss the research status and hotspots related to breeding， planting， harvest， processing and storage of Lycium L. in China. Methods Relevant literature about breeding， planting， harvest， processing and storage of Lycium L. in CNKI from January 2004 to December 2013 was retrieved by computers. CiteSpaceⅡ was introduced to carry out key word analysis， high-frequency key word obtaining， co-occurrence network of high-frequency key words， and dendrogram of high-frequency words. Results Totally 759 articles were included. Key words about breeding were “genetic diversity”， “male sterile”， “its sequence”， “callus issue”， and “anther culture”. Key words about planting were “output”， “quality”， “hard twig cuttage”， “irrigation amount”. Key words about harvesting and processing were “picking machine of Lycium L.”， “drying kiln of Lycium L.”， “hot air drying”， and “combined drying”. Key words about storage were “pesticide residue”， “heavy metal”， and “organophosphorus pesticide”. Co-occurrence network of high-frequency key words showed that the research hotspots were pesticide residue， test of heavy metal and the storage of fresh fruits. Dendrogram of high-frequency key words showed that the high-frequency key words were “package”， “refreshment”， and “lycium barbarum polysaccharide”. Conclusion The research hotspots of planting of Lycium L. are planting skills effecting the output and quality of Lycium L.； In the field of harvesting and processing of Lycium L.， design and research of picking machine has replaced traditional manual picking. Modern hot air drying has already replaced traditional drying in the sun or drying skills； In the aspect of storage of Lycium L.， the study on the refreshment of Lycium L. has attached attention.
