松材线虫是松树的毁灭性病害,松树占我国森林资源的1/4,松林的存亡直接关乎林业的兴衰。本研究以松材线虫入侵林地内的土壤因子为主要研究对象,意图通过对得到的土壤样品理化性质的分析,探究受到该病害入侵的不同生态系统中土壤因子的差异性。结果表明,在研究受松材线虫病入侵的生态系统的土壤因子时,P含量、全N量和有机质含量这三个指标是非常重要的。

Pine wood nematode is a devastating disease of pine, pine accounts for 1/4 of our forest resources, the survival of pine forest directly related to the rise and fall of forestry. In this study, the soil factors in pine wood nematode intruded into the forest were the main research objects. The purpose of this study is to analyze the physical and chemical properties of the obtained soil samples to explore the differences of soil factors in different ecosystems affected by this disease. The results showed that in the study of soil factors affected by pine wood nematode invasion, three indexes of P content, total N content and organic matter content were very important.
