摘　　要：采用微波技术对松材线虫病疫木板材进行除害处理并获得成功。通过对相关技术指标的测试,计算出松材线虫(Bursaphelenchus xylophilus(Steiner&Buhrer)Nickle)和松褐天牛(Monochamus altermatusHope)致死临界温度及不同厚度、湿度板材的有效处理时间。该项处理技术能够100%杀死松材线虫病疫木板材内松褐天牛和松材线虫,符合国家对松材线虫病疫木安全利用的要求。经安全性和稳定性测试,微波泄漏量低于国家标准,微波输出功率稳定,输送系统运转正常。该项处理技术高效快捷、安全可靠,对环境友好、先进适用,可用于一定厚度板材的检疫除害处理。Microwave technique was successfully applied to kill pine wood nematode in timber for the first time in China. By means of testing the corresponding＇technical indices, both the critical temperatures of death of pine wood nematode and rusty pine longicorn beetle and the effective processing time of pine wood with different thickness and humidity are figured out. After being processed, rusty pine longicorn beetle and pine wood nematode in infected wood could be killed 100%, which meets the corresponding requirements of the national standard. The results of safety and stability measurement indicate that the leak of microwave is lower than that of the national standard, while output power of microwave is stable, and the conveying system runs normally. The processing technique, which is efficient, environmentfriendly, safe and reliable, advanced and applicable, provides a new method for processing pine wood infected with nematode and could be applied to kill pests in sheets within a certain thickness. It is safe to say that the technique will play an important role in elimination of pests for infected pine wood.
