| Abstract: | The biomass of spruce (Picea koraiensis) plantation in the Suiling district of Heilongjiang Province was systematicly studied. Net productivities and their distribution biomass of the stem, bark, branch, leaf and root on the arborous layer of spruce plantation from 6 to 31 a were investigated and stem analyses using mean sample method. The regression equations for estimating the biomass of different organs of individual trees were set up.The result showed that the biomass of stand was 151 t/hm-2 and net productivity was 11 ~14 t/(hm2.a). |
