摘　　要：萌条是超短轮伐期生物质能源林生物量的主要组成部分。通过对杨柳不同树(品)种、不同采伐年限及不同密度设置的能源林生物量与萌条各性状的相关性进行的试验研究,结果表明:能源林树(品)种的生长特性能显著影响萌条数与生物量的相关性,密度、轮伐期对其相关性也有明显影响。杨、柳大型乔木树种营造的能源林中,较短的采伐模式下萌条平均高生长量以及主干萌条高生长量能够做为生物量的重要决定因素;轮伐期较长的采伐模式,只有侧芽不易萌发的品种生物量能以主干萌条高生长量做参考依据;在包括萌条数量在内的5个性状指标中,主干萌条地径生长量与生物量正相关关系最为密切。Sprout is the main source of biomass for energy forest which has a very short rotation.The experiments of the correlation coefficient between the biomass of energy forest and the traits of sprout with different tree species,different cutting years and densities were conducted,result shows that the growth characteristics of energy forest species,densities and rotation period can significantly affect the correlation between sprout number and biomass.In the energy forest created with large arbor species such as poplar and willow,the mean height growth of sprout and height growth of sprout for trunk can be used as important determinants of biomass in shorter cutting mode.However,only the biomass of the varieties with less germination of lateral bud could be determined by the increments of height growth of sprout for trunk in the cutting pattern of longer rotation.Among the five traits including sprout quantity,the growth height of ground diameter of sprout for trunk is most correlated with biomass.
