摘　　要：对撑绿竹纸浆林施肥采用"3414"三因素四水平的二次回归试验设计,建立了N、P、K施肥与撑绿竹新竹产量间的回归模型。结果表明,施用N肥是影响撑绿竹新竹产量的主导因子,N、K2O间存在一定程度的正交互作用。在设定的N、P、K肥0-3水平内符合肥料效应函数法原理的前提下,通过频率分析可得推荐施肥用量:纯N为177.744-261.096kg·hm-2,平均219.420kg·hm-2;P2O5为29.700-45.900kg·hm-2,平均37.800kg·hm-2;K2O为100.800-152.910kg·hm-2,平均126.855kg·hm-2。施肥比例:N∶P2O5∶K2O=1∶0.172∶0.578。Through the application of fertilizer to Bambusa pervariabilis×Dendrocalamopsis daii pulpwood timber with ＂3414＂ three-factor quadratic regression orthogonal design optimization, analysis of the N, P, K fertilization and production of Bambusa pervariabilis×Dendrocalamopsis daii between the regression model, statistical analysis indicates that： Nitrogen is the dominant factor affecting Bambusa pervariabilis×Dendrocalamopsis daii production,and there is a positive interaction between N and K2O to certain extent. The set of N, P, K fertilizer levels of 0-3, the range of fertilizer effect function under the premise of law principle, the fertilizing amount can be obtained by frequency analysis： N 177.744-261.096 kg·hm^-2, with an average 219.420 kg·hm^-2; P2O5 29.700-45.900 kg·hm^-2, with an average 37.800 kg·hm^-2; K2O 100.800-152.910 kg·hm^-2, with an average 126.855 kg·hm^-2. The fertilizer ratio： N∶P2O5∶K2O=1∶0.172∶0.578.
