Correlation analysis between soil factors with biomass and medicinal components of Paris polyphylla var. chinensis

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.
