摘 要:松枯死木的及时、有效除害处理,对防治松材线虫病具有重要意义。为探讨生产上环保、安全、经济适用的松枯死木处理方法,2015~2016年在福建省南安罗山国有林场采用了覆土法、覆草覆土法、覆草法、网罩法4种无害化方法除害处理松枯死木,结果表明:覆土法、覆草覆土法、网罩法3种无害化方法松墨天牛杀灭率可达100%,还能克服传统的就地熏蒸和烧毁等措施可能造成的环境污染、森林火灾等问题,是可推广的除害方式。但覆草覆土法相比覆土法和网罩法成本略高。生产上倡导就地除害松病、枯死木,以避免松病、枯死木运输至异地实施安全利用时导致疫病扩散。在土层较厚、易于挖穴操作的地方,推荐使用覆草覆土法;路途较偏远,山高路陡,行人较少的地方,推荐网罩法。Timely and effective pest control of pine dead wood is of great significance for the control of pine wood nematode.In order to explore environmentally friendly,safe and economically applicable treatment methods for dead pine trees in production,four harmless methods including soil covering method,straw and soil covering method,straw covering method and net covering method were used to treat dead pine trees in State-Owned Forestry Farm of Luoshan in Nan’an,Fujian Province from 2015 to 2016.The results showed that the killing rate of the three harmless methods of soil covering method,straw and soil covering method and net covering method could reach 100%,and it could also overcome the environmental pollution and forest fire caused by traditional fumigation and burning,which could be popularized.In production,it is recommended to kill pine disease and dead wood on the spot.In the place with thick soil layer and easy to dig holes,it is recommended to use straw and soil covering method;in the place with remote road,steep mountain road and fewer pedestrians,it is recommended to use net covering method,which can avoid the spread of disease caused by the implementation safe use of dead wood after transport to another place.
