ABSTRACT
OBJECTIVE: To explore the relation between the quality of the Herb-Paris and their cultivation of soil nutritional status. METHODS: The soil nutrient status (0 - 30 cm) of Paris polyphylla var. yunnanensis, artificially cultivated areas were determined in 2009 and their rhizome qualities harvested in 2010 were evaluated respectively. Determination of 0 - 30cm depth soil ingredients status with soil conventional five nutritional analysis method of 29 artificial cultivation area, 9 Prefectures of Yunnan Province. RESULTS: Soil nutrient has effect on quality of Herb-Paris medicinal ingredients. CONCLUSION: The multiple linear stepwise regression analysis reveals that among a certain range, the steroidal saponin VII content is positively correlated with the content of soil organic matter and pH. Steroidal saponin H content is positively correlated with the content of soil organic matter, available P and pH. Steroidal saponin I is positively correlated with the content of available K, but negatively correlated with the content of available Herb-Paris, and steroidal saponin II is positively correlated with the content of soil organic matter and available K.
