Abstract: Objective: Study the fertilizer requirement characteristics of P. tenuifolia on nitrogen fertilizer、fertiphos and potash manure to improve cultural practices in producing region. Method: The experiment was determined by the orthogonal experiment design of three factors and three deals. Result: There is significance difference for the yield per mu in different amount of fertilizer applied. Conclusion: The proper fertilizer proportion of P. tenuifolia is N:P:K=1:1.04:1.34, and the amount of fertilizer applied is annually urea 26kg, concentrated superphosphate 27kg and potassium sulphate 32kg for per 667m2.
