摘要

在广东亚热带气候条件下,不同剂型的季铵铜（ACQ）、柠檬酸铜（CC）、百菌清（CTL）及铜铬砷（CCA）处理马尾松、湿地松、毛白杨后的野外埋地耐久性能的结果表明:毛白杨防腐处理后不宜在与地接触的条件使用,可以用于快速初步评价防腐剂的野外耐久性能;吸药量6.4,8,.5 kg/m3时,CTL处理后的木材不宜在与地接触的条件下使用;湿地松的ACQ-B及CC防腐、防白蚁效果相当;对于马尾松、湿地松,吸药量6.0,6,.8 kg/m3时,ACQ-B、CC处理的试材埋地6年后,防腐效果较好,防白蚁的效果尚可;对于马尾松、湿地松,吸药量约10 kg/m3时,ACQ-B、CC、CCA处理的试材埋地6年后,防腐、防白蚁效果较好。

Abstract

The durability of ACQ,copper citrate（CC）,Chlorothalonil and CCA treated Masson Pine,Slash Pine and Poplar were tested at a typical sub-tropical area in Guangdong province in Southern China.The results showed that not all preservative-treated Poplar could be used in ground contact circumstances,and neither could Chlorothalonil be used for ground contact conditions at a retention of 6.4～8.5 kg/m,3,.ACQ-B and CC treated Slash Pine,under the same retention level,had almost equivalent effect for preventing decay and termite infestation.The stakes of Masson Pine and Slash Pine,treated by ACQ-B and CC at a retention of 6.0～6.8 kg/m,3, in a 6-year-test,exhibited good resistance for decay and fare resistance for termites;while that treated by ACQ-B,CC and CCA,around a retention of 10 kg/m,3,have extremely fine resistance for decay and termites after the 6-year test.
