1、应用木腐菌处理松材线虫病疫木伐桩的研究【摘要】疫木伐桩是松材线虫病除治中的难点,利用木腐菌处理松材线虫病疫木伐桩是一项环保、有效的伐桩处理技术。本试验研究了13种木腐菌对松材线虫的抑制作用以及对马尾松木块和松材线虫病疫木伐桩的分解能力,通过对木腐菌的筛选、优良菌株的扩繁,将优良木腐菌应用于松材线虫病疫木伐桩野外试验,结果表明,供试菌株除裂褶菌和杂色云芝外,其他菌都能抑制松材线虫的生长与繁殖,其中虎掌菌、松生拟层孔菌、粗皮侧耳、硫磺菌、茯苓和灵芝等6个菌能完全抑制松材线虫的数量。对马尾松木块及疫木伐桩的分解试验结果表明,接菌处理70d后,虎掌菌、松生
2、拟层孔菌、粗皮侧耳、硫磺菌和茯苓5个木腐菌都分别对疫木伐桩起到了一定的分解作用,特别是硫磺菌对疫木伐桩具有较强的分解力和定殖力以及对线虫的抑杀作用,可作为今后利用木腐菌处理松材线虫病病死树伐桩的潜力菌。【关键词】松褐天牛;松材线虫;木腐菌;疫木;伐桩;分解StudyonUsingWood-rottingFungitoTreatStumpsofDeadWoodCausedbyPWN(Bursaphelenchusxylophilus)12DENGXi-kin1LIUHui2LUO-Huiwin4HUANGYan-hong4(3.GanzhouFore
