摘要
在黑龙江省丰林国家级自然保护区原始森林。汤原牙签厂贮木场等地对寄生在桦木上的主要腐朽菌进行了调查研究;在实验室中用土壤木块法测定了白桦、黑桦、枫桦边材对彩绒革盖菌(白腐菌)和桦剥孔菌(褐菌)的天然耐腐力;试验研究了BBF,CCB,CCA和CCF四种防腐剂的效果,并利用DU—7紫外分光光度仪探测BBF防腐剂的渗透。结果表明:以桦革褶菌、桦褶孔菌、彩绒革盖菌、木蹄菌等为代表的白腐菌是引起桦木腐朽的主要真菌;三种桦木均属不耐腐朽树种;其防腐效果,BBF最佳。其次是CCB。再次是CCA、CCF。
The decayed fungi was investigated in primary forest of Fenglin Natural Preserve, and log yard of Tangyuan; the decayed resistance of three kinds of birches sapwood to white fungi and brown fungi was studied in laboratory with four kinds of preservatives of BBF, CCB, CCA and CCF. The permeability of BBF was conducted with DU-7 ultra spectrometer. The results show that white fungi is the main fungi for birch decayed. three kinds of birch are all easy to be decayed,the effect of preservativc is in order of BBF,CCB, CCA, and CCF.
