5个刺槐品种枝干生物量和热值测定对比分析

Comparison Analysis of Biomass and Calorific Values of Five Robinia pseudoacacia L. Varieties

对山东省费县大青山林场8年生刺槐新品种多彩青山、紫艳青山、壮美青山、绿满青山和鲁刺10(CK)的生物量和单株枝干含热量进行测定和试验分析,选择高生物量、高热值的刺槐新品种进行能源林栽培经营。研究结果表明:5个刺槐品种枝干干质量在58.40～132.89 kg,从大到小排序为壮美青山、多彩青山、绿满青山、紫艳青山、CK; 5个刺槐品种单株枝干含热量在1 066.71～2 481.86 MJ; 5个刺槐品种各器官干质量热值中,树叶的单位干质量热值最高,树干次之,树皮的最低。综合生物量和热值分析,对刺槐进行能源林经营的品种选择是有效的,壮美青山和多彩青山选做能源林刺槐品种栽培最为理想。

The biomass and individual branch-trunk dry mass caloric value of 8-year Robinia pseudoacacia L.new varieties R.pseudoacacia‘Duocai Qingshan’,R.pseudoacacia‘Ziyan Qingshan’,R.pseudoacacia‘Zhuangmei Qingshan’,R.pseudoacacia‘Lvman Qingshan’and R.pseudoacacia‘Luci 10’(CK)were measured and tested in Mount Daqing Forest Farm of Feixian County,Shandong Province,and the high biomass high calorific value of the R.pseudoacacia L.new species was selected to carry on the energy forest cultivation and management.The branch and trunk dry mass of 5 varieties was between 58.40 and 132.89 kg,indescending order of R.pseudoacacia‘Zhuangmei Qingshan’,R.pseudoacacia‘Duocai Qingshan’,R.pseudoacacia‘Lvman Qingshan’,R.pseudoacacia‘Ziyan Qingshan’,and CK.The branch and trunk dry mass calorific value of each branch of 5 varieties of Locust was between 1 066.71 and 2 481.86 MJ.In the dry mass caloric value of different organs,the highest is the unit dry heat value of leaves,trunk if second,and the bark has the lowest unit dry mass value.According to comprehensive caloric value and biomass analysis,it is effective to choose R.pseudoacacia L.for management of energy forest,R.pseudoacacia‘Zhuangmei Qingshan’and R.pseudoacacia‘Duocai Qingshan’are the best choice for R.pseudoacacia L.cultivation.
