竹材非常容易受到霉菌的侵害，这是由于竹子中含有丰富的糖、淀粉和蛋白质。冷水、热水、苯/乙醇、乙醇/乙醚、1%NaOH、1%HCl等溶剂均能溶解竹材中的相应成分，有助于提高竹材对霉菌的抗性。为了研究竹材表面营养与霉变的关系，在实验室和田间对不同溶剂处理后的竹材进行了防霉性测定。结果表明，经冷水、热水、苯/乙醇或乙醇/乙醚处理的竹材，其对霉菌的抗性与对照基本相同，室内试验10 d内竹材表面就被菌丝覆盖，田间试验5周内竹材表面就被菌丝覆盖。1%NaOH和1%HCl处理对竹材的防霉性有一定的促进作用，其中1%HCl处理的防霉效果最好，尤其是在低温下防霉效果最好。
Bamboo timber is very vulnerable to mould fungi, a characteristic that is attributed to the rich sugar, starch, and protein present in bamboo. Solvents including cold water, hot water, benzene/ethanol, ethanol/ether, 1% NaOH, and 1% HCl can dissolve corresponding components from bamboo, which might be helpful to the resistance of bamboo against mould fungi. In order to study the relationship between surface nutrition and mildew of bamboo, mould resistances of bamboo blocks treated with different solvents were tested in the laboratory and field. Results showed that bamboo treated with cold water, hot water, benzene/ethanol or ethanol/ether had almost the same resistances with the controls against mould fungi, and the surfaces became covered with mycelium within 10 days in laboratory tests, and 5 weeks in field tests. 1% NaOH and 1% HCl were helpful to the mould resistance of bamboo, of which, 1% HCl treatments behaved the best, especially in the s.
