摘要：测定了5个乔灌木柳树无性系和6个杨树无性系夏季、冬季不同组分的干质量热值,研究了1年生杨、柳无性系皮部和干部在夏季和冬季的干质量热值的变化情况,以及随着平茬次数的增加1年生柳树无性系全株热值的变化规律。结果表明:杨、柳树无性系不同组分在不同季节干质量热值的变化不完全一样,但是在冬季皮部、干部和全株热值均比在夏季时高;5个柳树无性系不同季节年份的干质量热值变化规律基本一致,冬季热值为1年生根1年生干>2年生根1年生干>3年生根1年生干,柳树无性系间的1年生根1年生干冬季热值与2年生根1年生干冬季热值的差异极显著,与3年生根1年生干冬季热值的差异显著,灌木柳的热值比乔木柳的高;6个杨树无性系(1年生根1年生干)的冬季全株干质量热值>夏季全株干质量热值,但无性系间差异均不显著;1年生柳树全株冬季干质量热值普遍高于杨树。
The gross caloric value of five Salix and six Populus clones harvested in summer and winter were determined to explore the change of gross caloric value on one-year-old poplar and willow bark and trunk in the two seasons.And the gross caloric value change on the whole tree of one-year-old willow clones after several harvests were also discussed.The results show that the gross caloric value of different fractions of willow and poplar are not the same.However,the gross caloric values of the bark,trunk and the whole tree in winter were higher than those in summer;the variation of five willow clones were consistent with each other,the gross caloric value of one-year-old trunk with one-year-old root in winterthe gross caloric value of one-year-old trunk with two-year-old root in winterthe gross caloric value of one-year-old trunk with three-year-old root in winter,the gross caloric value of one-year-old trunk with one-year-old root in winter and that of one-year-old trunk with two-year-old root in winter among different willow clones reached significant level at P=0.01,the gross caloric value of one-year-old trunk with three-year-old root in winter among different willow clones reached significant level at P=0.05,the gross caloric value of shrub willow were higher than that of tree willow;Concerning six poplar clones,the gross caloric value of one-year-old trunk with one-year-old root in winter was bigger than that in summer,the gross caloric value among different of poplar clones did not reach significant level and was similar.The whole tree gross caloric value of one-year-old willow clones was higher than those of poplar clones.
