摘  要：
采用四因素五水平二次通用旋转组合设计方法,建立了密度、氮、磷、钾施肥与巨桉纸浆原料林单位面积材积生长量之间的效应模型,经检验,二次回归模型拟合较好。通过对模型的主效应分析,明确了密度、氮、磷、钾肥4个因素中对巨桉纸浆原料林单位面积材积生长量作用大小依次为:密度>磷肥>钾肥>氮肥。对两因素交互效应的分析得出:氮肥与钾肥之间交互效应不显著。氮肥与磷肥之间存在一定的互补性,磷肥与钾肥之间具有协同性。经微机模拟寻优,氮、磷、钾三因素取95%的置信区间的高产栽培措施组合为:氮肥71～79g/株,磷肥96～100g/株,钾肥32～67g/株。

摘  要：
By using the design of quadratic common rotation including four factors, five levels, the basic models of efficiency were established between density, N, P, K and per area growth volume of 35 year Eucalyptus grandis pulpwood timber, and the quadratic regression models were simulated closely with reality by testing. The results of principalefficiency analysis and mutualefficiency analysis are as follows: Impacting per stand growth volume of Eucalyptus grandis pulpwood timber, the four factors are as follows from the high to the low: density>P>N>K. An obvious interaction does not appear between nitrogenous fertilizer and potash fertilizer. Nitrogenous fertilizer and phosphate fertilizer can exchange for each other to a certain extent and it is mutually beneficial relation between phosphate fertilizer and potash fertilizer. The combination high yield cultivated pattern is the following: N is 71～79?g/N, P is 96～100?g/N, K is 32～67?g/N. When the three factors of N, P, K are in the confidence limit of 95%.
