Background
Pine nematodes enter the xylem through the nutrient-supplemented wounds of monochamus alternatus and parasitize in the resin tract. Move while propagating in large quantities, gradually spread throughout the whole plant, and cause damage and death of parenchyma cells and epithelial cells of a resin tract, so that the plant loses water, and finally the whole plant withers. Pine trees infested with pine nematodes are the subjects of monochamus alternatus hopes for egg laying. In the next year, the monochamus alternatus hopes can carry a large amount of nematodes when emerging, and are inoculated on a healthy tree, and the cycle is repeated, so that the pine nematodes are spread.
The method is a reliable countermeasure for preventing the disease trees from spreading along the way in the carrying process, so as to cut off the spreading way of pine nematodes and achieve the purpose of preventing and treating the pine nematodes.
The diseased trees need to be cut down firstly, then cut into small sections on the spot, and finally ground on the spot to kill adult pine nematode, worm eggs, monochamus alternatus and worm eggs, so that special equipment for cutting down, cutting into sections and grinding diseased trees in wild complex areas is needed.
At present, large-scale machinery is available abroad for crushing diseased trees and stumps, such as a crusher manufactured by Germany, and a driver drives the crusher to roll and cut the diseased trees and the stumps back and forth by a front-mounted large-scale roller cutter, so that the aim of preventing and controlling pine nematodes is fulfilled.
