The Comparative Analysis of Biomass and Calorific Values among Four 5-Year-Old Locust Clones
摘要
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 3-1, 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 , 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' > 3-1 > 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 3-1, and the middle trunk would be the ideal part for energy, followed by branches.关键词
