Effects of Ecological Factors on Quality Difference Between Forestland Ginseng and Farmland Ginseng
The ecological environment is an important influencing factor that leads to differences in the quality of forestland ginseng and farmland ginseng.The content of ginsenosides in forestland ginseng and farmland ginseng was used as an indicator to analyze their quality differences,determined the physicochemical properties of rhizosphere soil,and conducted correlation,multiple stepwise regression,coefficient of variation,partial least squares discriminant analysis,and analytic hierarchy process comprehensive evaluation analysis on the measurement results.The results showed that there were significant differences in ginsenoside content and soil physicochemical properties between forestland ginseng and farmland ginseng.Analysis of coefficient of variation showed that the coefficient of variation of most ecological factor indicators in farmland ginseng was greater than that in forestland ginseng.The results of correlation,multiple stepwise regression,and partial least squares discriminant analysis showed a significant correlation between soil factors such as the highest temperature,the lowest temperature,pH,alkaline nitrogen,and available phosphorus with ginsenosides.The results of the analytic hierarchy process showed significant differences in soil quality among different cultivation modes.Multiple statistical results showed that the highest temperature,the lowest temperature,and pH were the main factors affecting the content of ginsenosides,while alkaline nitrogen,available phosphorus,and soil moisture were secondary factors.Above results indicated that the highest temperature,the lowest temperature,pH,alkaline nitrogen,available phosphorus,and soil moisture were important factors affecting the quality differences between forestland ginseng and farmland ginseng.The results provided a theoretical basis for analyzing the formation of ginseng quality and planting production.
