摘要
对1a生杨树无性系能源林材性进行了比较分析。对4个无性系的生长量、生物量、木材基本密度、纤维素含量、C含量以及热值和灰分进行了测定。结果表明:杨树无性系的生长量年动态均符合“慢-快-慢”的S型生长规律。杨树无性系Y208的纤维素含量、C含量和热值较其他3个无性系高。
This article was an investigation of one year old Poplar clone. Y208, Y328, NL351, MA）young trees. The indexes of growth, biomass and the wood properties of timber basic density, cellulose content, C content, caloric values, and ash content were determined in 4 poplar plantations used as energy. The results showed that the S curves of ＂slow-fast-slow＂ for 4 clones were observed during one year growth period. The content of cellulose, carbon, and the caloric value of clone Y208 were higher than the other three clones （Y328, NL351 ,MA）.
