摘要
目的:建立不同产地川芎药材品质与产地土壤因子的相关性,确定影响川芎药材质量的主要因素。方法:采用TFW-VII型土壤养分·水分综合测定仪测定土壤样品中有机质、速效磷、速效钾及硝态氮等土壤营养值,采用SPSS统计软件分析土壤营养值与川芎有效成分含量间的相关性。结果:相关性分析显示土壤速效钾与川芎有效成分相关性最大,速效钾与川芎总荧光物质、藁苯内酯均呈极显著负相关,而与洋川芎内酯呈极显著正相关。其次是有机质、土壤pH、速效磷,而硝态氮与所选有效成分均无显著相关性。结论:影响川芎有效成分的主要土壤因素是速效钾和有机质。同时通过分析还发现川芎有效成分之间、土壤营养值之间均存在一定的相关关系,由此说明土壤养分对于川芎药材品质的影响并非单因素作用,而是由协同作用来共同影响川芎药材品质。该结论可为川芎的合理栽培、管理提供理论依据。
Objective： To establish the correlation between the quality of Rhizoma Ligusticum Chuanxiong from different producing areas and soil factors, and find the main factors that influence the quality of Rhizoma Ligusticum chuanxiong. Method： TFW-VII soil nutrient and moisture tester was used to determine the content of organic matter, available P, available K and nitrate-nitrogen. SPSS statistical software was used to analyze the correlation between the soil nutrition values and the content of effective components in Rhizoma Ligusticum Chuanxiong. Result： The statistical results showed that the content of available K had obvious correlations with the content of effective components in Rhizoma Ligusticum Chuanxiong. The content of available K had a significant negative correlation with the content of total fluorescence materials and ligustilide, while it had a significant positive correlation with the content of senkyunolide. The second were organic matter, pH and available P, while the content of nitrate-nitrogen had no significant correlation with the effective components. Conclusion： The main soil factors to influence the content of effective components in Rhizoma Ligusticum Chuanxiong were available K and organic matter. The content of effective components had certain correlation with the soil nutrition values, that is to say the soil nutrient influenced on the quality of Rhizoma Ligusticum Chuanxiong is not single factor function, but synergistic effect. This conclusion can provide theory support for reasonable cultivation and maintenance of Rhizoma Ligusticum Chuanxiong.
