This invention discloses a method for establishing a spectral characteristic database of trees affected by wood nematode, involving the interdisciplinary fields of forestry disease monitoring, spectral analysis, and database technology. By capturing subtle spectral changes in pine needles in the red and near-infrared bands, this invention can identify signs of infection before obvious symptoms appear on the tree's surface. Through a multi-step, multi-index comprehensive analysis method, it effectively eliminates interference from other ground features such as forest land and bare soil. The established dedicated spectral model and indices are highly targeted, achieving higher classification and identification accuracy than using a single general index, significantly reducing the false positive rate.

The present application also provides a method for cutting the surface of a pine tree to collect resin, an auxiliary device for cutting the surface of a pine tree and a method for using the device. The method for cutting the surface of a pine tree to collect resin ensures normal growth of the pine tree by retaining a bark section between two cuts to form a nutrient zone with a width of 0.5-1 cm, which ensures normal upward transport of nutrients.
