摘要
为了研究造林初植密度对翅荚木木材热值等的影响,笔者采用造林初植密度试验与木材采样测试相结合的方法对幼龄翅荚木的生长量、生物量、热值等进行研究。结果表明：4年生翅荚木胸径、树高、生物量等生长量密度效应显著。木材热值密度效应不显著,当翅荚木造林初植密度为10001~40002株/hm2时,其单木热值约18200J/g;当初植密度为3334~6667株/hm2时,其单木热值约19000J/g。当翅荚木造林初植密度达40002株/hm2时,4年生翅荚木每hm2生物量达94.2t,生物总量相当于58.69t标煤。翅荚木是较好的纤维能源植物。
In order to study the effect of initial planting density on caloric value of Zenia insignis Chun, by both initial planting density test and sampling and testing of wood, the growth, biomass and caloric value of young Zenia insignis Chun were studied. The results suggested that the diameter at breast height, tree height and biomass of four-year old Zenia l＂nsignis Chun were significantly different. There was no significantly difference on caloric value of wood density effect. When the initial planting density was 10001-40002 plants per hm2, the caloric value of individual tree was 18200 J/g around. The initial planting density was 3334-6667 plants per hm2, the caloric value of individual tree was 19000 J/g around. When the initial planting density was 40002 plants per hm2, four-year old Zenia insignis Chun biomass reached 94.2 t per hm2, the total biomass were equated with 58.69 t standard coal. Zenia insignis Chun was a good fiber energy plants.
