摘要
采用多因素正交和单因素随机区组对比试验方法，对蓝桉培育进行了为期五年的定位研究，成功研制出容器壮苗培育、定植季节、造林密度、施肥措施等关键技术。纸浆原料林定向培育应3月初播种培育容器壮苗，6月及时出圃定植，初植密度2500株／hm2，重施有机类底肥，次年2－4月混施N肥和P肥。试验林分表现出显著的早期速生性。
A set of 5-year trials was established according to talldom ororthogonal design to develop silvicultural regime specificly for short rotationpulpwood plantation of Eucalyptus globulus Labill. The results indieate thatcontainer seedling raising should start in early Marcl so that the best plantingseason can be guaranteed, initial density of 2500 P. /ha. resulted in bettergrowth and lighter competition, organic base fertilzer is essent ial and fastreleasing N and P fertilizers slould be applied mixedly in the fallowing Feb. toAyril.
