| 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。

| Abstract: | 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. pseudoacacia ‘Yuciyihao’>Hungary tetraploie). The calorific values of the different parts were between 3 800-3 960 and 3 840-4 000 kcal·kg-1, 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 plants 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. |
