| 为研究土壤因子对华重楼生长和药效成分积累的影响,该研究利用高效液相色谱技术(HPLC)以及相关性和多元线性回归分析方法,测定了华重楼不同产地土壤成分、样品的生物量和重楼皂苷的含量,分析了土壤因子与华重楼生物量和药效成分的相关性。结果表明:(1)不同产地土壤成分和华重楼产量及其重楼皂苷含量均有差异。(2)相关性分析显示,干重与有机质、全氮、碱解氮显著正相关,重楼皂苷Ⅰ与有机质和速效磷显著正相关,重楼皂苷Ⅱ与速效磷和速效钾显著正相关,而重楼皂苷Ⅶ与土壤各因子的相关性不显著。(3)多元线性回归分析显示,影响干重的主导因子为碱解氮,影响重楼皂苷Ⅰ的主导因子为有机质,影响重楼皂苷Ⅱ的主导因子为速效磷,而重楼皂苷Ⅱ与碱解氮呈线性负相关。综合分析认为,影响华重楼干重的土壤因子主要是碱解氮,而影响华重楼皂苷含量的土壤因子主要为有机质和速效磷,该研究结果为华重楼的人工栽培提供了理论依据。 |

| Abstract: |
| Inorder to study the effect of soil factors on the growth and medicinal component of Paris polyphylla var. chinensis, the biomass and the polyphyllin contents of different samples from different origins were determined, soil composition was measured, and the correlations between soil factors biomass and medicinal components were analyzed. The results were as follows:(1)There were differences in soil composition in different place, while the yield and polyphyllin content in samples in different places were quite different.(2)Correlation analysis showed that the dry weight was significantly positively correlated with organic matter, total nitrogen, and alkaline nitrogen, the polyphyllin I content was significantly positively related with organic matter and available phosphorus, the polyphyllin Ⅱ content was significantly positively correlated with available phosphorus and available potassium.(3)Multiple linear regression analysis showed that the dry weight was dominantly affected by alkaline nitrogen, the polyphyllin I was dominantly affected by organic matter, the polyphyllin Ⅱ was dominantly affected by available phosphorus, and was linear negatively correlated with alkaline nitrogen. In summary, the main soil factors affecting dry weight was alkaline nitrogen, the main soil factors affecting the polyphyllin total content was organic matter and available phosphorus. The results provide a support for the artificial cultivation. |
