摘　　要：施肥对尾赤桉无性系DH201-2生长和材性影响的试验研究结果表明,施肥能明显提高林分生长量和纤维产量,但对DH201-2无性系木材的纤维长度、长宽比、基本密度以及纤维含量等影响较小,不同施肥处理的材性均符合木材制浆造纸工艺的要求。提出闽南山地DH201-2纤维材培育的合理施肥组合为N 150 kg.hm-2+P2O5150 kg.hm-2+K2O 100 kg.hm-2,该施肥组合不但可促进林分速生、丰产,而且可以达到优质。Examination of fertilization influencing growth and timber quality of Eucalyptus urophylla × E. camaldulensis clone DH201-2. The results showed that fertilization could obviously increase yield of stands and timber fiber, but less influence on the fiber length, the ratio of length to width, the basic density and the content of timber. The timber quality of different fertilization accorded with techniques of paper pulp production. The reasonable fertilization combination was N150kg·hm^-2＋P2O5 150kg·hm^-2＋K2O 100kg·hm^-2 on mountainous regions of southern Fujian, not only enhancing tree fast growth and high yield, but also achieving high quality.
