摘　　要：研究了冷水、热水、苯+醇、苯+乙醚、10 g.kg-1盐酸(HCl)和10 g.kg-1氢氧化钠溶液(NaOH)浸提处理后毛竹Phyllostachys pubescens的霉变性能。结果表明:①经10 g.kg-1HCl浸提的竹片防木霉Trichoderma viride,橘青霉Penicillium citrinum和黑曲霉Aspergillus niger效果最佳,接种1个月后试样平均被害值均为0。②经10 g.kg-1NaOH浸提的竹片对木霉、橘青霉有较好的防霉效果。经10 g.kg-1NaOH浸提的竹片如不经过水洗,接种1个月后试样平均被害值均为0;而经过水洗后防霉效果有不同程度下降,对木霉和橘青霉而言,处理后试样平均被害值分别为1.58和0.35。经10 g.kg-1NaOH浸提的竹片对于黑曲霉的防治效果不佳,10 g.kg-1NaOH浸提后的竹片水洗前后对黑曲霉的试样平均被害值分别为1.82和2.79。③经冷水、热水、苯+醇、苯+乙醚浸提竹片的防霉效果均不佳,7 d以后试样平均被害值均已达到3.00以上,主要原因在于不同溶液浸提出的竹材内含物成分和数量不同。The anti-mold effects of PhyUostachys pubescens extracted with solutions such as cold water, hot water, benzene＋alcohol, benzene ＋ ether, 10 g·kg^-1 HCI and 10g·kg^-1 NaOH were studied. The results were as follows： （1） Bamboo specimens extracted with 10 g·kg^-1 HCI could successfully resist the testing molds including Trichoderma viride, PeniciUium citrinum and Aspergillus niger. The average infection values of the treated specimens after a month were all zero. （2） Bamboo specimens extracted with 10g·kg^-1 NaOH resisted Trichoderma viride and PeniciUium citrinum better than Aispergillus niger. When the specimens were extracted only with 10 g·kg^-1 NaOH, the infection values were all zero. But when they were extracted with 10 g·kg^-1 NaOH and washed with water, the resistances to Trichoderma viride and PeniciUium citrinum decreased dramatically, and the infection values being 1.58 and 0.35 respectively. Bamboo timbers treated with 10g·kg^-1 NaOH had poor resistance to AspergiUus niger, and the infection values of the treated specimens before and after being washed with water were 1.82 and 2.79 respectively. （3） Bamboo timbers extracted with cold water, hot water, benzene ＋ alcohol, benzene ＋ ether were hardly effective to the testing mold. The infection values of the treated specimens were all over 3.00. The different anti-mold effects were caused by different types and amounts of extractives. [Ch, 3 fig. 2 tab. 12 ref. ]
