| Abstract: | In this paper,the effects of N,P and K interaction on licorice flavanone content were studied.A sandy soil in the Yanghuang newly-irrigated areas,Hongsibu,Ningxia Province was used.The result showed that the effect of N,P and K on Licorice flavanone content was P>N>K and the interaction factors were P×K>N×P>N×K.In the Yanghuang newly-irrigated areas,the content of total flavanone in cultivated Licorice could be increased by more than 5.0% if the amount of fertilizers were applied as follows: N 119.6-138.8 kg hm-2,P2O5 153.2-178.5 kg hm-2 and K2O 90.9-105.6 kg hm-2. |
