三种常用方法防治松干线虫的研究

在病虫害防治过程中切断传染路径是重要的传统防治方法。松干线虫的主要传染媒介是松墨天牛,伐除病死木、熏蒸方法处理残余伐根、诱捕器捕杀天牛成虫3种方法相结合,处理染病林分,并和没有进行处理的林分进行比较,试验表明,染病个体植株数明显下降,松墨天牛虫口密度大幅度降低。基于这样的思路,设计了试验方案,收集大量数据,并进行数据处理分析,得出结论,为松干线虫的防治提供理论依据。

Study on Three Common Methods to Control Pine Stem Nematode

cutting off the transmission route is an important traditional control method in the process of pest control. Pine stem nematode pine sawyer ink, is the main vectors of the cutting method in addition to the dead wood, fumigation processing residual root cutting, adult trap killing of longicorn combined three methods, hm 2ndling sick forest, forest and deal with and without comparison, the experiments show that the number of the infected individual plants declined obviously, pine sawyer ink densities slash, this experiment based on the idea, design the experiment scheme, a great deal of data collection, data processing and analysis, conclusion, provide theoretical basis for the prevention and control of the pine stem nematode.
