摘要
通过不同的微波温度处理松材线虫病死木原木,观察了微波对松材线虫疫木中松墨天牛幼虫及松材线虫存活的影响,同时初步研究了微波处理后原木在材性上的变化情况。结果表明,当微波处理温度达到50℃时,保持5 min,可完全杀灭病木中的松墨天牛幼虫;当微波处理温度达到55℃时,保持5 min,松材线虫完全死亡;温度在60℃左右时,对木材的开裂、抗弯弹性、抗弯强度等材性影响不显著,经微波处理的疫木可正常利用。因此5,5℃的微波处理可作为松材线虫疫木除害的有效方法。
Through the different temperatures of microwave treatment on the infected wood of Bursaphelenchus xylophilus,the survival of Monochamus alternatus larvae and the pine wood nematode as well as the wood properties（elastic modulus and static bending strength） were studied.The results showed that when the temperature of microwave treatment was reached to 50℃ for 5 minutes,the larvae of M.alternatus were completely killed in the diseased wood.The temperature of the microwave treatment was reached to 55℃ for 5 minutes,the pine wood nematode was all dead.The temperature of microwave treatment was around 60℃,the crack,elastic modulus and static bending strength the diseased wood were not significantly different from the control and could be used normally.Comprehensively,the microwave treatment of 55℃ was an effective way to treat the woods infected with B.xylophilus.
