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.
