Problems solved by technology

The above treatment has problems such as incomplete killing, high cost, complicated treatment process, and reuse of treated infected wood.
[0005] In the prior art, there are the following problems in the summary of the treatment methods of infected wood: the crushing method is difficult to kill completely; the steel wire mesh method has high treatment costs, and the treatment cost per plant is as high as 500-600 yuan per bead, which is difficult to promote and use on a large scale Bagging fumigation, fiber heat treatment and log disinfecting treatment, on the one hand, the branches and leaves are more difficult to deal with, on the other hand, how to use the diseased wood after treatment is the key. Supply, through the establishment of traditional wood utilization methods such as solid wood processing plants, fiberboard factories, and particleboard factories, it is not feasible

Abstract

The invention discloses a preparation method of a pine wood nematode infected wood landscape flooring material, and belongs to the technical field of wood processing. The preparation method comprises the steps of cutting down infected wood, slicing the infected wood, sorting wood chips, sterilizing the wood chips, coloring the wood chips and drying the wood chips, the pine wood nematode infected wood is processed into a garden landscape flooring material, propagation of pine wood nematodes can be effectively avoided, a safe and reliable new green material is provided for landscape greening, and a systematic solution is provided for treatment and utilization of the pine wood nematode infected wood.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a preparation method of a pine wood nematode infested wood landscape paving material. Background technique [0002] Pine wilt, also known as pine blight, is a devastating pest. It is spread in pine trees through vector insects such as monochamus monochamus, thereby causing pine tree diseases. After being infected by pine wood nematode, the needle leaves are yellowish brown or reddish brown, wilting and drooping, the resin secretion stops, and the long beetle intrusion holes or traces of spawning can be observed in the trunk, and the whole plant of the diseased tree dries up and dies, and finally rots. Pine wood nematode disease has occurred in the United States, Canada, Mexico, Japan, Korea and other countries. The total area of ​​pine forests in my country is about 900 million mu, and the prevention of pine wood nematode has become a difficult problem for the developme...
