摘要
采用真空法对湿加松(Pinus elliottii Х p.catibaea)木材进行防腐处理,研究不同防腐处理工艺防腐处理效果、树干不同离地高度木材和径向不同部位木材防腐可处理性的差异。结果表明防腐处理工艺、树干离地高度和径向不同部位均对湿加松木材我药量有显著影响(P〈0.01)。防腐处理工艺的处理时间、真空度是影响湿加松防腐可处理性的主要因素。湿加松径向内层载药量显著高于外层(P〈0.05);湿加松径向木材和枝下高部分(0~9.3m)轴向木材的载药量与木材气干密度呈负相关;树干离地高度为93~11.3m的湿加松木材载药量最小。
Preservative treatability of Pinus elliottiix P.earibaea wood was studied in this paper. Results showed that both treatment processes and wood position had great effect on P. elliottii Х P.earibaea wood preservation treatability. Vacuum degree and treatment time were the main factors of wood preservation treatability; the preservative retention of wood from inner annual layer is higher than that of wood from outer annual layer;and there was an evident negative correlation between wood density and the treatability of samples from different trunk position ( radial direction and wood at height under branch ) . Samples at 9.3-11.3 m above ground were more difficult to treat than other wood section.
