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6．4～8．5kg／m^3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6．0～6．8kg／m^3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10kg／m^3时，ACQ-B、CC、CCA处理的试材埋地6年后，防腐、防白蚁效果较好。
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.
