To explore the rational phosphorus levels of Ningxia Ural licorice under artificial cultivation condition，different phosphorus application rate on yield and economic impact in central drought areas of Ningxia Ural licorice were studied.The results showed that there was a significantly linear correlation between soil phosphorus content and licorice production，and with the increase of phosphate level，the production of licorice increasing significant.When P2O5 reached 155 kg/hm2，the production reached the highest 6 927.75 kg/hm2，the Phosphate levels continue to increase，the production of licorice increased was not significantly.The best economic benefits could be achieved when the P2O5 content was 75~150 kg/hm2 .
