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。

Diseased stumps is cure difficulty of pine wood nematode disease, it is an environmental protection, control technology effectively that using wood rotting fungi treated pine wood nematode infected stumps. In th is study, the 13 kinds of wood-rotting fungi were chosen to evaluate the irrelation with Bursaphelenchus xylophilus ( PWN ) , the ability to decompose the wood specimens of Pinus massoniana and the stumps of dead pine trees caused by PWN, by screening and propagating good strains of the wood-rotting fungi, and using to field test, the results showed that all the wood-rotting fungi tested had certa in nematicidal effects on PWN except Schizophyllum commune and Coriolus versicolor, and 6 strains could completely inhibit the pine wood nematode, they are Tremellodon gelatinosum, Fomitopsis pinicola, Pleurotus ostreatus, Laetiporus sulphureus, Poria cocos, Ganoderma lucidum. The test results of decomposing pine wood and disease stumps showed that they had played some decomposition effect to the diseased stumps, after treating stumps inoculating above 6 strains for 70 d, especially, Laetiporus sulphureus showed higher ability to decomposing and colonising the stumps,and inhibiting and killing nematodes, it could be used to treat stumps of dead wood caused by PWN in the future.
