studies on the pathogenicity of 10 years old black pine inoculated with aseptic pine wood nematode 无菌松材线虫对10年生黑松致病性的研究
studies on influence of poplar canker and pine wood nematode on the electrical indexes of tree stem 杨树溃疡病及松材线虫病对树体干部电指标的影响
the related research papers, in which the studies on proportion, status and trend of pine wood nematode were reported in recent years, were reviewed and analyzed 目前松材线虫病的研究仍是日本国森林病虫害的主要研究课题。
namely, if the red symptom of pine wood nematode disease on pines appear, we'll accurately locate the position of the trees and supervise the epidemic situation of the disease in time by remote sensing monitoring 利用该方法能够对有松材线虫病症状的松林准确、快速定位,从而起到及时监测疫情的作用。
