Protecting net and method for diseased tree infected with nematodes

Abstract

The invention discloses a protecting net and method for a diseased tree infected with nematodes. The protecting net comprises a mesh bag with an opening and a mesh cover, wherein the mesh cover is arranged at the opening of the mesh bag and connected with the mesh bag through a zipper in an openable manner. When the protecting net is used to treat the diseased tree, the diseased tree infected withthe pine wood nematodes is sealed in the mesh bag, the mesh cover is used to close the mesh bag by zipping the zipper to form a sealed protecting net structure, long-horned beetles in the diseased tree is sealed in the protecting net and starved to death, the spreading of the pine wood nematodes is cut off, and destructive disaster caused by the spreading to a pine forest is avoided; the pure natural treatment manner is used, the treatment of the diseased tree is simple and convenient and high in safety, nematode spreading is controlled after the long-horned beetles are starved to death, threat to pine trees which are not infected with the nematodes is reduced and alleviated, and greater contribution is made for the creation of a green ecological environment.

Description

technical field [0001] The invention relates to the technical field of treatment of infested wood, in particular to a protection net and a protection method for nematode infested wood. Background technique [0002] Pine wood nematode is a devastating disease of Pinus species, which is mainly transmitted by vector insects such as monochamus. Therefore, it is one of the main means to control pine wood nematode disease to kill the pine wood nematode that is infested with the disease. At present, the treatment of pine wood nematode infested wood mainly includes heat treatment, drug fumigation treatment and in situ incineration treatment. Heat treatment is to put the diseased wood in a hot air drying kiln, or a special hot air (steam) drying box for wood. When it is heated, it needs special heat treatment equipment and continuous heating treatment. The treatment process is complicated and the cost is high. . Drug fumigation treatment uses drugs such as methyl bromide, sulfuryl...

AI Technical Summary

Problems solved by technology

Heat treatment is to put the diseased wood in a hot air drying kiln, or a special hot air (steam) drying box for wood. When it is heated, it needs special heat treatment equipment and continuous heating treatment. The treatment process is complicated and the cost is high.

Drug fumigation treatment uses drugs such as methyl bromide or sulfuryl fluoride or aluminum phosphide to fumigate the diseased wood. Drug fumigation has certain toxicity, especially aluminum phosphide, which is highly toxic and has low safety.

Although incineration on the spot is easy to deal with, the infected wood after burning has no economic value, and it is easy to cause the loss of infected wood.
