摘要：用自然接种后套皿异温异湿培养法和人工接种毛竹材致霉菌混合液后同温异湿培养法,对4～5度的毛竹冬竹材和秋竹材进行霉变测定,结果表明:在温热条件下(26～32℃),毛竹材在饱和湿度时霉变最严重,霉变程度与湿度成正相关。用分月暴露后套皿保湿法对毛竹4度(8年生)冬竹材进行霉变测定,结果表明:全年12个月中,七月、二月和一月暴露的毛竹块材,霉变程度极显著地低于其他9个月份,分析系因该三月气温气湿不利于致霉菌在毛竹材上定殖繁育之故。提出两种用于竹材抗霉性快速测定及防霉处理效果评估的实验室方法和供目前生产上暂用的竹材霉变程度分级标准;并根据研究结果,提出了适于生产上采用的几点竹材防霉建议。
Small rectangular Mao bamboo pieces were incubated after natural inoculation and artificial inoculation separately under different temperatures and relative humidities (RH) to test the effects of main environmental factors on bamboo timber moulding. The results from the multiple contrasts of the tests showed that under temperatures of 26℃ to 32℃, most sorious moulding of Mao bamboo timber occurred at 100 % RH; the extent of moulding was positively correlated to RH; the moulding extent of Mao bamboo ripped timber exposed in July, February and January was significantly lower than that exposed in other months of the year.The two laboratory inoculation methods are recommended for the first time for rapid testing of the natural resistance of bamboo timber to moulds and evaluation of mould control treatments of bamboos. Also a primary standard for grading the extent of bamboo timber moulding was put forward for current use.Suggestions were made to store bamboo timber in a warehouse of special structure, with high base pillars under the floor and large windows; to put the bamboo timber and handcrafts in cross-ways in order to maximize air circulation and decrease the humidity at the surface of bamboo goods and choose suitable processing season to reduce mould damage.
