摘　　要：为明确大花序桉木材干燥特性随树龄变化的规律,并依此为木材加工利用提供依据和支持,利用百度试验法对29 a生和35 a生大花序桉的木材干燥特性进行了对比研究,结果表明:29 a生和35 a生大花序桉的初期开裂、内裂、截面变形、扭曲变形、干燥速度等级分别为2级、3级、3级、3级、4级和4级、4级、3级、4级、5级;35 a生大花序桉干燥速度更慢,初期开裂以及后期开裂和截面变形更严重;参照百度试验缺陷等级及干燥缺陷对应的干燥条件制定了29 a和35 a大花序桉木材干燥基准。The drying characteristics of 29a and 35a Eucalyptus cloeziana wood were determined by using a 100℃test method.The result showed that the grades of initial cracking,internal cracking,section deformation,twisting deformation,drying speed of 29 a and 35 a Eucalyptus cloeziana wood were 2,3,3,3,4 and 4,4,3,4,5 respectively.In comparison,the drying speed of the 35 a Eucalyptus cloeziana wood is slower,and its initial cracking,later cracking and section deformation are more serious.With reference to the 100℃test defect level and the drying conditions corresponding to the drying defects,the 29 a and 35 a Eucalyptus cloeziana wood drying schedule were established.
