Abstract:
The rhizosphere soil of forsythia and the different origin of forsythia were used as the materials，by using the method of the determination of the nitrogen，the flame photometry and the 2015 Edition Pharmacopoeia method，the correlation of pH in root soil，total nitrogen，available phosphorus，potassium content and medicinal active ingredient content was studied.The results showed that forsythoside A and soil factors of total nitrogen，available phosphorus，available potassium showed a significant correlation，correlation coefficients respectively were -0.303*,-0.300* and -0.299*.There was no significance among forsythin and total nitrogen，available phosphorus，available potassium.Forsythia alcohol soluble extraction and available phosphorus were statistically significant negation correlation，coefficients was -0.312*.By gray correlation degree analysis，it was found that the forsythia alcohol soluble extractive，forsythoside A，forsythin were correlated with pH and available potassium in the soil.The correlation coefficients between forsythoside A and available phosphorus，available potassium，total nitrogen and pH respectively were 0.852 7,0.851 6,0.844 6 and 0.844 4，the results suggested that the accumulation of forsythiaside A content and soil factors were closely related.The correlation coefficients between forsythin and pH，available potassium were 0.487 2 and 0.473 2 respectively；the correlation coefficients between alcohol soluble extraction and pH，available potassium were 0.721 8 and 0.514 5.From the above，it was found that the effective components of forsythia was the most closely related to the pH and total potassium of soil factors.From analysis，it was known that N，P，K content of rhizosphere soil had correlation with the accumulatin of effective components in forsythia，in the standardized cultivation of forsythia，N,P,K fertilizer ratio should be reasonably used.
