摘　　要：桉树人工林木材是一种典型难干材,做好桉木干燥,有利于桉木加工利用,提高桉木利用率。实验以巨尾桉小径木材为材料,用百度试验法编制了干燥基准,并对扇形锯材的干燥做了初步的研究。低温低湿的干燥基准保证了巨尾桉板材的干燥质量,却使干燥周期大幅度延长。试验发现,扇形锯材能有效地避免横弯缺陷,在同样保证干燥质量的情况下,比板材干燥周期缩短约1/3,干燥质量较好,无可见缺陷,终含水率达到一定标准,具有较好发展前景。Eucalyptus grandis×E.urophylla was one kind of typical difficult seasoned wood. Drying is the key of lumber use. The test take the small diameter logs of Eucalyptus grandis×E.urophylla Plantation which were collected from Heyuan Guangdong Province as materials, make the drying schedule with 100℃ test method, and do the preliminary study on Drying Technology of Fan-shaped Saw Timber of Eucalyptus grandis× E.urophylla. The drying quality is good while the drying period is long in the low temperature drying experiment Discovered in the fan-shaped saw timber drying test that the fan-shaped saw timber can avoid the horizontal curved distortion. In the similar guarantee dry quality＇s situation, it reduces nearly 1/3 drying period compared to the plate. The dry quality is good. It does not have obviously drying defects. The moisture content finally achieves certain standard. It has the good prospects for development.
