摘要
[目的]探究五味子果实有效成分含量与土壤因子的相关性,为五味子栽培过程中合理施肥提供理论依据。[方法]采用HPLC法对五味子果实中5种木脂素类成分进行含量测定,利用酶活检测试剂盒对土壤样品进行检测,通过Spearman相关性分析,主成分分析、聚类分析和灰色关联分析等分析方法探究五味子产地气候因子特征及5种木脂素类成分与土壤因子之间的相关性。[结果]土壤中有效钾、有机质、蔗糖酶及脲酶的活性增高对促进五味子有效成分的形成和积累有积极作用,但速效磷的含量增高对五味子有效成分的形成有消极作用。[结论]土壤中有效钾、有机质的含量能够在一定程度上促进五味子果实中木脂素类成分的积累,在合理范围内施用钾肥和有机肥,能够在一定程度上高五味子品质。
[Objective]The aim was to explore the correlation between the content of active ingredients and soil factors,so as to provide theoretical basis for rational fertilization in the process of Schisandra chinensis cultivation.[Method]Five lignans in S.chinensis fruit were determined by HPLC.Soil samples were detected by soil fertilizer rapid tester and enzyme activity detection kit.Spearman correlation analysis,principal component analysis Cluster analysis and grey correlation analysis were used to explore the characteristics of climate factors and the correlation between five lignans and soil factors.[Result]The increased activities of available potassium,organic matter,sucrase and urease in soil played a positive role in promoting the formation and accumulation of active ingredients of S.chinensis,but the increased content of available phosphorus had a negative effect on the formation ofactive ingredients of S.chinensis.[Conclusion]The content of available potassium and organic matter in soil can promote the accumulation of lignans in S.chinensis fruit to a certain extent.The application of potassium fertilizer and organic fertilizer within a reasonable range can improve the quality of S.chinensis to a certain extent,which requires subsequent confirmatory tests.
