N, P, K formulas for fertilization with young Phoebe bournei plantations in Fujian Province

Abstract: In order to improve the fertilization effectiveness of young Phoebe bournei plantations. A field experiment was conducted in Mingxi County of Fujian Province based on a D-saturated optimal design with three factors: N, P, and K. The growth effects for young P. bournei plantations were then examined with a frequency analysis and RCB. Results showed that N, P, and K fertilizer efficiency was positive for growth of tree height and crown width (with N>P>K) and for increasing diameter at ground-level (with P>N>K). The frequency analysis showed that compared to ck, the expected tree height was 120%, the expected diameter at ground-level was 120% and the expected crown width was 110%. In these experimental plots, optimum fertilization rates (in gtree-1) for young P. bournei plantations were 16.81-21.61 for N, 5.76-9.64 for P2O5, and 3.31-6.44 for K2O with a 95% confidence interval with a frequency analysis method; the best ratio of m(N):m(P2O5):m(K2O) was 3.94:1.57:1.00. Then providing the basis for scientific fertilization of P. bournei plantations.[Ch, 3 tab. 15 ref.]
