摘　　要：采用硫磺菌菌株6600、杂色云芝菌株6923、松生拟层孔菌菌株W11、茯苓菌株6284和粗皮侧耳菌株6221接种处理松材线虫病病死树伐桩,研究5个菌株对伐桩的分解能力以及对伐桩内松材线虫的作用情况。结果表明:硫磺菌菌株6600对伐桩的分解能力以及对伐桩内松材线虫的抑杀作用都最强;对伐桩内松材线虫数量与伐桩样品质量的相关分析表明两者呈极显著的正相关。该研究为今后在实际生产中利用木腐菌处理伐桩奠定了重要的基础。The stumps of the dead wood caused by Bursaphelenchus xylophilus （PWN） were one of the most important infection source of pine wilt disease. Effective measure taken to treat stumps would be helpful to improve efficiency to control the disease. In this study, Laetiporus sulphureus strain 6600, Coriolus versicolor strain 6923, Fomitopsis pinicola strain W11, Poria cocos strain 6284 and Pleurotus ostreatus strain 6221 were chosen to treat stumps of the dead wood caused by PWN, the ability of decomposing stumps and the effects of PWN were studied in this paper. The results showed that the strain of 6600 had the highest ability to decompose stumps and certain nematicidal effects on PWN. The correlation analysis indicated that the num^r of PWN had significant and positive relation with the weight of stumps. The study sets important basis of using wood-rotting fungi for treating stumps of the dead wood in the future.
