摘　　要：据对35/66杨的对比试验表明,在初始密度较高时,资源紧缺地区,为提高木材产出,可以适当提高造林密度,以缩短杨木生产周期,初始造林密度在1 000株/hm2左右,为培育大径杨木可采用间伐措施,间伐强度要适中,在第4年间伐50%,使保留密度在500株/hm2左右;以培育大径材为目标时,为能获得最大量的大径杨木,一般不宜采用密植后再间伐的经营措施。Comparison test on poplar 35/66 demonstrated that forestated density could increased to 1000/ha for shortening production circle. Intermediate cutting at the 4th was for cultivating large diameter trees. The density remained 50%. When target was for large diameter wood, intermediate cutting would not be used.
