摘　　要：本文采用416D饱和最优回归设计在砂壤质冲积土设置田间试验。回归分析和频率分析的结果表明,大青杨优质高产的综合施肥方案为N:16.46g/m^2,P_2O_5:3.24g/m^2,K_2O:17.0g/m^2,沸石:31.61g/m^2。The 416 D saturated optimum regressive design was adopted to evaluate the effect of mixing application of N, P, K and Si fertilizers on the dry matter and seedling quality of Cathay poplar on a sandy loam aluvium. The results of regressive and frequency analyses showed that the optimum fertilization pattern was N: 16. 64 g/m2, P2O5: 3. 24 g/m2, K2O:17. 0 g/m2, and zeolite: 31.61 g/m2.
