In this study,the wood-rotting fungi were chosen to evaluate their relation with Bursaphelenchus xylophilus(PWN),the ability to decompose the wood specimens of Pinus massoniana and the stumps of dead pine trees caused by PWN.
测试了木腐菌对松材线虫繁殖的影响以及对马尾松木块和松材线虫病病死树伐桩的分解能力,结果表明,供试菌株除裂褶菌菌株外,其他菌株都能抑制松材线虫的繁殖,其中松材线虫在松生拟层孔菌菌株W10、W11,硫磺菌菌株5452、6600,粗皮侧耳菌株6221,虎掌菌菌株6320,茯苓菌株6284,灵芝菌株6501菌落上完全不能存活。
The stumps of the dead wood caused by Bursaphelenchus xylophilus(PWN) is one of the important infection source of pine wilt disease.
松材线虫病病死树伐桩是松材线虫病重要侵染源之一,采取有效措施处理伐桩将有利于提高该病的防治效果。
The law of stump sprouting of broad-leaved tree species was studied in eastern forest area in Northeast China by the investigation of fixed sampling.
对固定样地调查,采用伐桩的径、高度、萌芽的数量、萌芽的生长情况等指标,分析东北东部林区主要阔叶树种的伐桩萌芽更新规律。
The number of sprout spot was related with biological features but not related with height and diameter of stumps as it changed with randomicity.
萌芽点数按伐桩高度和伐桩直径分布均呈随机性,表明萌芽点数与伐桩高度和伐桩直径无关,仅与其生物学特性有关。
