Abstract:

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(2O5),K and peanut cake to be applied at 0.219 5,0.825 8,0.190 6,2.305 5 t5hm-2 respectively. The fertilizing project for the highest yield was that N, P(2O5),K and peanut cake applied respectively at (0.218 6,) (0.826 2,)(0.189 9,) and (2.306 4) t5hm-2.

Key words: Dendrocalamus latiflorus, shoot used bamboo plantation, fertilizer in each prescription, yield, number of emerging shoots, effect
