| Abstract: | Biomass and alimentary compositions of twigs and leaves of Robinia pseudoacacia L.were determined. Accumulating patterns of the alimentary substances, relationship between treeage and the alimentary content, and effect of different drying ways on the alimentary contentwere investigated. The biomass of a 1-year-old coppice was 7 184. 4kg/hm2, of which that ofleaves was 3 384. 8kg/hm2 and twigs 3 799. 6kg/hm2. In the foliage there were 17 kinds of animo acids whose content was as high as 13. 61% and increased with the tree age. The averagegross protein amount was 20. 18%. Higher alimentary content was found in the leaves than intwigs, but the gross protein content was contrary. Feasible drying ways of the foliage served asfodder were oven-drying and shade-drying. |
