修剪清理健康树枯枝防治松材线虫病研究
|
摘要
松材线虫为国际头号检疫性病原,主要传播媒介为松墨天牛,扩散蔓延迅速,防治困难。在以清除枯死木为主的综合防治基础上,增加修剪清理健康树枯枝措施。结果表明,经过5年防治,试验区枯枝被蛀率下降到不足0.01%,松墨天牛携带松材线虫的比率下降到2.75%,病死枯木数量下降到个位数。综合防治措施成效显著,修剪清理枯枝措施增益作用明显。
Bursaphelenchus xylophilus is the most important quarantine pathogen in the world, the main media is Monochamus alternatus, it has spread rapidly and is difficult to prevent and control. On the basis of comprehensive control, pruning and clearing of dead wood was added. The results showed that, after 5 years of prevention and control, the decayed rate of dead branches in the test area decreased to less than 0.01%, the rate of Bursaphelenchus xylophilus carried by Monochamus alternatus decreased to 2.75%, and the number of dead wood decreased to single digits. Comprehensive control measures were effective, and pruning and clearing of dead branches had obvious effects.
