摘要 The quadratic regression orthogonal design with five factors was adopted to shoot-used Dendrocalamus latiflorus forest planted on hills in Nanjing stated-owned forest farm. Results showed that the regression equation between fertilizer of N, P, K, organic fertilizer and shoot yield fitted very well, and that of N, P and shoots number fitted well too. The best fertilizing project was that N, P（P2O5 ）, K and peanut cake to be applied at 0.219 5,0.825 8,0. 190 6,2.305 5 t· hm^-2 respectively. The fertilizing project for the highest yield was that N, P（ P2O5 ）, K and peanut cake applied respectively at 0.218 6, 0.826 2, 0.189 9, and 2.306 4 t·hm^-2 .
