Pine wood nematode control method

Abstract

The invention relates to a pine wood nematode control method. The method comprises the steps that in the site where the pine wood nematode epidemic situation is found, diseased trees and tree roots are smashed, insecticides are added, and the smashed diseased trees and the tree roots are buried, so that the pine wood nematode epidemic situation is timely and effectively controlled. According to the method, the diseased trees are cut down by using a chain saw, and branches are sawed off; then trunks and the branches are sawed into tree sections by using a multi-blade rotary-cutting sawing machine; then the tree sections are put into a tree section crusher to be crushed into sawdust; stumps exposed on the ground are crushed by a stump crusher; the tree roots in the soil are crushed by usinga portable rotary drilling machine; pits for burying the sawdust are dug in the working site, plastic films are laid in the pits, then the sawdust is shoveled into the pits, the insecticides are addedinto the sawdust, the sawdust is covered with plastic films, and finally the sawdust is covered with soil and buried.

Description

technical field [0001] The invention belongs to the field of forestry machinery, and in particular relates to a method for preventing and controlling pine nematodes. Background technique [0002] The pine xylophilus enters the xylem through the nutrient-supplemented wound of the pine woody beetle, and parasitizes in the resin canal. It moves while proliferating in large numbers, and gradually spreads throughout the whole plant, and causes the destruction and death of resin duct parenchyma cells and epithelial cells, causing the plant to lose water, and finally the whole plant dies. Pine trees infested with pine wood nematodes are the targets of pine beetles for laying eggs. The following year, when the monochamus alternatus emerges, it will carry a large number of nematodes and inoculate them on "healthy trees". This cycle will lead to the spread of pine wood nematodes. [0003] Forest land clearing, cutting and burning of diseased and dying trees, and removal of diseased ...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved in the present invention is to provide a method for the prevention and control of pine wood nematodes in the prior art that transports diseased plants and stumps to a centralized location for treatment: low efficiency, poor effect and transmission along the road. Pine nematode control method: at the scene where the pine nematode epidemic is found, the diseased trees and shrubs are crushed on the spot, and the sawdust is added to the burial, so as to control the pine nematode epidemic in a timely and effective manner
