摘　　要：对河南省陕县5年生的3-I、豫刺槐1号、匈牙利四倍体、一般刺槐(CK)4个刺槐无性系的生物量、灰分含量、干质量热值和去灰分热值进行分析。结果表明:无性系间单位干质量热值和去灰分热值差异显著,分别在3750～3950kcal·kg-1与3800～4000kcal·kg-1之间,高低排序均为3-I>CK>豫刺槐1号>匈牙利四倍体;部位间单位干质量热值和去灰分热值差异显著,分别在3800～3960kcal·kg-1与3840～4000kcal·kg-1之间,高低排序均为树干中部>树枝>树干上部>树干下部;无性系间单株枝干干质量热值和去灰分热值差异显著,分别在10900～35000kcal与11000～35500kcal之间,无性系间单株枝干热值排序与枝干总生物量排序一致,均为豫刺槐1号>3-I>CK>匈牙利四倍体。综合热值、灰分含量和生物量分析,对刺槐进行能源林经营的品种选择是有效的,无性系豫刺槐1号选做能源刺槐树种栽培最为理想,3-I次之;树干中部为理想能量部位,树枝次之。This article analyzed the biomass, ash contents, calorific values of dry weight and the deashing dry weight of four 5-year-old locust clones, such as 3-I, Robinia pseudoacacia, ＇ Yuciyihao＇ , Hungary tetraploie and common locust （CK） in Shan county, Henan Province. The results showed that the calorific values per dry mass and the deashing dry mass of clones were between 3 750 - 3 950 and 3 800 - 4 000 kcal-kg-1 , respectively （the order was： 3-I 〉 CK 〉 R. pseudoaeaeia ＇ Yuciyihao＇ 〉 Hungary tetraploie）. The calorific values of the different parts were between 3 800 -3 960 and 3 840 -4 000 kcal＇kg-I , respectively （the order was. middle portion of stem 〉 branches 〉 upper portion of stem 〉 lower portion of stem）. The calorific value of the dry mass and the deashing per the individual plant＇s branch or trunk were between 10 900- 35 000 and 11 000 -35 500 kcal.tree-1 respectively, with the same order as the branch-trunk total biomass, that is, （ Robinia pseudoacacia ＇ Yuciyihao＇ 〉 3-I 〉 CK 〉 Hungary tetraploie ）. In comprehensive analysis of the caloric value, ash contents and biomass, R. pseudoacacia ＇ Yuciyihao＇ would be the ideal clone which can be selected for energy cultivation, followed by 3-I, and the middle trunk would be the ideal part for energy, followed by branches.
