栗山天牛在辽宁省发生危害的规律及防治对策
|
摘要
栗山天牛是柞树林的毁灭性蛀干害虫,其危害不仅影响林木生长,破坏森林资源,而且还严重影响了森林生态效益的发挥。但由于近年来栗山天牛在防治上被忽视,加之气候干旱和立地条件瘠薄的林分抗虫能力低下的因素,使得栗山天牛呈现逐年加重趋势,局部地区已经成灾。栗山天牛的持续危害已成为制约辽宁省生态林业建设的重要因素。针对栗山天牛在辽宁省的危害规律和危害原因进行了分析,从营林措施、生物防治、化学防治及检疫控制等方面阐述了栗山天牛的防治对策。通过对策在实践中的实施,有效的控制了栗山天牛的危害,对保护柞树资源,促进林业发展发挥了巨大作用。
Lishan beetle is a destructive trunk borer in oak forest, the damage of which not only affects forest growth and destroy forest resources, but also severely affects the ecological benefits of forest. However, since the control of Lishan beetle has been neglected in recent years along with the factors of the drought climate and the low resistance of the barren stand in the site, the damage by Lishan beetle has appeared to be aggravated year by year with disasters disturbing partial areas. The sustainable damage of Lishan beetle has become an important factor restricting the ecological forestry construction in Liaoning Province. This paper analyzes the damage regularities and causes of Lishan beetle in Liaoning province and puts forward the countermeasures from the perspectives of forest management, biological control, chemical control and quarantine. Through the implementation of the countermeasures in practice, the damage of Lishan beetle has been effectively controlled, which plays a significant role in protecting oak resources and promoting the development of forestry.
