土壤因子与华重楼生物量和药效成分含量相关性分析

Analysis on correlation between soil factor and the growth and medicinal component of Paris polyphylla var

摘要:为了研究土壤因子对华重楼生长和药效成分积累的影响,为人工栽培种植提供理论 依据,该文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。

英文摘要:Inorder to study the effect of soil factors on the the growth and medicinal component of Paris polyphylla var. chinensis, and to provide a support for the artificial cultivation, the biomass and the polyphyllins content of different samples from different origins were determined, and soil composition was measured. Then the correlation between soil factors and the growth , and medicinal component were analyzed. The results were as follows: (1)There were differences in soil composition in different place, while the yield and polyphyllins content in samples in different place 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 polyphyllins 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.
