Study on Biomass Distribution of Betula luminiferaat Different Ages
摘要
Abstract
The biomass distribution of Betula luminifera was studied at different ages,the results showed that： the biomass of Betula luminifera was increased with age,single plant biomass at 4a is 238.0% compared to 3a＇,is 363.4% to 2a＇.The composition of single plant biomass was different at different ages,The trunk proportion increased with age,which increased from 45.8% at 2a to 56.4% at 3a and 58.2% at 4a,The proportion of branch and leaf decreased by ages,the proportion of branche was 26.7% at 2a decreasd 20.5% at 3a and 21.6% at 4a,the proportion of leaves decreased from 3.6%at 2a to 2.3%,2.2% at 3a,4a respectively.The biomass distribution of root was taproot root lateral fine roots at different ages.The ratio of root to shoot decreased from0.31 at 2a to 0.22 at 4a.关键词
