AbstractThe orthogonal test design of was adopted to explore the regulatory effect of nitrogen.phosphorus and potassium application onthesedlinggrowhofEpimedmpubescensfro90to8OaysoldToughvaanceanalysisandmultplecomparsos.tasfoudatu reahadaverysignificantimpacton5indicatorsincludingsedingheight，stemdiameter，leafnumber，rootnumber，rolength（ P<0.001. ） The treatment group with 40g/m2 increased the seedling height by 26.0% and the stem diameter by 53.8% compared with the control group. When the superphosphate was at the level of 40g/m2 .it reached a very significant level in improving the stem diameter （ P<0.001 ）.The potassium sulfate treatment of 20g/m2 had a synergistic effect with the potassium element in the matrix background （0.633g/kg ）.and themaximum root length reached 168mm The optimal combination of comprehensive indicators was IzIzIzIz （ urea 40g/m2+ superphosphate 40g/m2+ （20 potassium sulfate 20g/m2 ）.This research revealed the nitrogen sensitivity characteristics and the mechanism of phosphorus and potasium synergisticactioniEiedmdineprovsetcalsisfortadadddinliofEmeinot mountain area.
