本文选用大兴安岭林区的主要树种——落叶松(Larix gmelini (Rupr.)Litvin)、樟子松(Pinus Sylvesstris. Var mongolica Litven)的火烧木为试材,以林区普遍泛滥的松针层孔菌(Phellinus. Pini)、硫磺(火旬)孔菌(Laetiporus. Sulphureu)和壳囊孢(cytospoya.sp)为试验菌种,试验研究了CCA,ACC和CS三种防腐剂的效果及影响因素,并利用ESCA,原子吸收光谱仪探测防腐剂的渗透,利用SEM观察菌丝在试材中的生长状况。结果表明:CCA的效果最好,其次是ACC,再次是CS。在三个菌种中,腐朽力最强的是硫磺(火旬)孔菌,其次是松针层孔菌,再次为壳囊孢。
In this paper, firewood from Larix gmelini (Rupr.) Litvin and Pinus Sylvesstris var. Mongolica Litven was selected as the test materials in the forest of Daxing’anling, Phellinus Pini, Laetiporus Sulphureu and Cytospoya sp. Were used as test strains to study the effects and influencing factors of CCA, ACC and CS preservatives. ESCA was used to detect the penetration of preservatives by atomic absorption spectroscopy. SEM was used to observe the growth of mycelium in the test material. The results showed that CCA was the best, followed by ACC and CS again. Among the three strains, the decaying force is the strongest sulfur (fire Xun) bacteria, followed by pine needle-hole bacteria, again as Cystospora.
