| 摘 要： | 目的:研究土壤养分与云南黄连产量及有效成分含量之间的相关性.方法:测定了13个土壤化学性质指标,以及云南黄连根茎生物量和根茎中小檗碱、药根碱、巴马汀的含量,对所测得的指标进行了因子分析和相关分析.结果:从土壤化学性质指标中提取了3个因子(总方差贡献率86.9％),其中钙(Ca)、镁(Mg)、铁(Fe)、锰(Mn)、锌(Zn)与第1因子有较强的相关性,有机质、氮(N)、有效N、有效磷(P)、有效钾(K)与第2因子有较强的相关性.云南黄连产量与土壤中有效P含量呈极显著正相关(P＜0.01),相关系数达到0.931,与土壤有效N含量呈显著正相关(P＜0.05),相关系数为0.703；云南黄连根茎小檗碱含量与土壤有效P含量呈显著正相关(P＜0.05),相关系数为0.680.结论:在有效N和有效P含量高的土壤中,云南黄连产量和小檗碱含量较高.

| Abstract: | The correlations between soil nutrition and yield as well as active compound contents of Coptis teeta were analyzed. The contents of 13 soil factors, rhizome biomass and the content of berberine, jatrorrhizine, and palmatine in rhizome of C. teeta were determined, and analyzed by factor analysis (FA) and correlation analysis (CA). FA showed that the first three factors accounted for 86.9% of the total variance. The contents of Ca, Mg, Fe, Mn, and Zn correlated with the first factor. The content of organic matter, N, available N, available P, and available K correlated with the second factor. CA showed that yield of C. teeta had a significant positive correlation with available P (r=0.931) at 0.01 level, and available N (r=0.703) at 0.05 level. The content of berberine of C. teeta had a significant positive correlation with available P (r=0.680) at 0.05 level. The yield and berberine content of C. teeta were high in the soil with high contents of available N and available P. |
