长岛综合试验区松材线虫病发生及防治对策

Outbreak and Control of Pine Wood Nematode Disease in Yantai Changdao Comprehensive Test Area

为给长岛科学评估和防控松材线虫危害提供依据,本文概述了长岛从1990年松材线虫病被发现以来的发生历史,分析了松林树种单一、树龄老化严重、极端气候等因素对长岛松材线虫病影响,并导致该病害蔓延发展的趋势,提出了建设监测预警体系、完善检验检疫体系、化学防治、生物防治、物理防治、营林改造等防治对策,以期为同类型地区有效防控松材线虫病蔓延提供技术参考。

This paper summarized the occurrence history of pine wood nematode disease since the first discovery in Changdao in 1990. The factors causing the disease severity like mono-culture, aging of trees, extreme climate change was analyzed. Monitoring, early-warning system as well as quarantine measures and countermeasures including chemical, physical and biological ways were suggested.
