摘　　要：以尼泊尔虎克龙竹Dendrocalamus hookeri,尼泊尔马甲竹Bambusa teres和埃塞俄比亚高地竹Yushania alpina竹材制成的竹帘层积材为研究对象,选用不同质量分数的有机碘化物、商用防霉剂、桐油和硝化纤维清漆处理板材,参照国家标准GB/T 18261-2000《防霉剂防治木材霉菌及蓝变菌的试验方法》进行处理材防霉试验,分析不同竹种、不同处理方式对竹帘层积材防霉性能的影响。结果表明:3种竹帘层积材素材均不能防霉、防蓝变(P<0.05);不同竹种对防霉效果影响不明显,不同处理方式对防蓝变、防霉效率影响极显著(P<0.01),尼泊尔马甲竹制成的层积材防蓝变能力优于另外2种竹材(P<0.05);选用质量分数为3%有机碘化物与硝化纤维清漆联合涂刷处理基本达到防治霉菌要求;选用质量分数为5%有机碘化物与硝化纤维清漆联合涂刷处理的霉菌、蓝变防治效力达到100%。Laminated bamboo curtain lumber（LBCL） was manufactured from Dendrocalamus hookeri, Bambusa teres, and Yushania alpina all from Nepal or Ethiopia, and was coated with commercial mold inhibitors, 3-iodo-2-propynyl butyl carbamate（IPBC）, Tung oil, or nitro-cellulose lacquer to improve anti-mildew capabilities. In the laboratory, resistance of both coated and uncoated LBCL to blue-stain and mold fungi was evaluated using China National Standard GB/T 18261-2000. Results showed that the uncoated LBCL had no anti-mildew capabilities according to areas of mold infection. Bamboo species had little influence on mold resistance with LBCL（P0.05）; whereas, treatment methods had a strong effect on the mold resistance（P0.01）. LBCL made of B.teres had slightly better resistance to Botryodiplodia theobromae than the other two bamboo species（P0.05）,but LBCL coated with 3% IPBC and lacquer was basically resistant to B. theobromae and Trichoderma lignorum. The most effective treatment method that was an LBCL with 5% IPBC and lacquer coating provided 100%resistance to B. theobromae and T. lignorum was the most effective.
