摘要：

研究板蓝根质量与土壤因子的相关性，筛选影响其质量的主导因子。HPLC法测定甘肃不同产地板蓝根核苷类、告依春有效成分的含量，理化分析法进行土壤因子（有机质，PH，全氮，铵态氮，硝态氮，全磷，速效磷，全钾，速效钾）的测定，应用相关分析及灰色关联度分析进行综合分析。结果表明尿苷与速效钾的相关系数为-0.828*；腺苷与全钾的相关系数为-0.863**；告依春与全氮的相关系数为-0.800*，告依春与铵态氮的相关系数为-0.772*。鸟苷和告依春中铵态N的关联系数最大，分别为0.9444和0.9559；尿苷中，pH值的关联系数最大，为0.9505；腺苷中全氮的关联系数最大，为0.8609；上述所有成分中，全P、全K的关联系数均次之。无论选择土壤，还是生产中施肥，应重视和合理使用N、P和K条件对板蓝根质量的影响。

Abstract:

The correlation between soil factors and the quality of radix was studied, of which the leading affecting factor was also screened out. HPLC method was applied to determine the content of active ingredients from different origins in Gansu, including nucleosides, epigoitrin. Physico-chemical analysis used to detect soil factor, including organic matter, pH, total nitrogen, ammonium nitrogen, nitrate nitrogen, total phosphorus, available phosphorus, total potassium and available potassium. The application of correlation analysis and gray correlation analysis were made to complicate a comprehensive analysis. The results showed that correlation coefficient of uridine and available potassium was -0.828*; adenosine and total potassium was 0.863**; epigoitrin and total nitrogen was -0.800*, epigoitrin and ammonium nitrogen was -0.772*; the maximum correlation coefficient was ammonium nitrogen in vernine and epigoitrin that were 0.9444 and 0.9559, respectively; pH in uridine was 0.9505; total nitrogen in adenosine reached 0.8609; of all the compositions, the correlation coefficients of total P, total K followed. Therefore, special attentions should be paid to the effects of N, P and K conditions on the quality of radix in the choice of soil and fertilizer.
