Description

Recycling Method of Wood Damaged with Pine Nematode

The present invention relates to a method for recycling pine worm nematode victims and suspicions, and to recycle the pine worms and suspicions affected by re-nematotic diseases by heat treatment and extinction of re-nematodes parasitic on pine worms and suspicions. The present invention relates to a method for recycling pine tree nematode disease victims and suspect trees using heat treatment.

In general, pine re-nematode disease is a parasitic in the body of the sea salt sky cow, and when the adult insect of the sea salt sky eats the leaves of the pine tree, the pine tree is dried up by the re-nematode, which is invaded by the tree. It is called 'pine aids'. A pine nematode is a nematode that is around 1mm in size. It is a pest that blocks water and nutrients in the tree tissues and kills the tree. The species of the species is infected with pine, red pine, pine, etc. % Test. Symptoms of infection include browning of leaves and sagging down in the shape of an umbrella. After 6 days of infestation, the leaves sag, and on the 20th, the leaves begin to wither, and after 30 days the leaves rapidly turn red and die.

The damage process of the pine tree by the nematode and the mediator, the sea salt sky cow, is as follows.

In May-July, when the adult larvae eat the healthy pine shoots, the worms mediated by the worms invade into the pine tree through the wound, and in June-August, 200,000 larvae are paired after 20 days. The conifers begin to rot by spreading throughout the tree and destroying the tissues, and the larvae scattered in the bark of the dead or dead trees that hatched rosin secretion incubate in June to October, adding to the subbark layer. To grow. At this time, the dead larva and re-nematode are distributed together in the dead tree. And after the larvae of the 11th to the following year, the larvae make pupas in the wood, and then they become pupas. In this case, worms scattered in the damaged or dead wood tissues gather around the pupa, and then invade into the body of allegory. Re-nematode retention of mediators averages 70%.

In order to remove them, the conventional method of controlling pine nematode disease and the use of the damage tree are the fumigation method of killing the nematode by injecting drugs, which is cut down the trees killed by pine nematode disease and stacked in 1 ~ 2㎥ size and It is a method of fumigation after cover and killing the larvae of larvae in the wood before escaping to adulthood. Sprinkle 1 liter per 1㎥ of the neck of the killer (methamphodium) on the stacked wood and seal it with vinyl immediately after chemical injection. If more than 7 days after the drug treatment, there is an excellent control effect of 100% mortality killing the inside of the wood, and do not need to move the infection tree is the most used control method. However, the fumigant used in this way can be harmful to humans and livestock, so be careful when using it, especially avoiding contact with eyes, nose, mouth and skin, so it is very cumbersome to use. It is spreading to the situation that does not have a great effect.

In addition, as a method of controlling pine worm nematode disease and utilizing the damage tree, a method of killing the larvae of larvae in the wood part by cutting down dead trees infected with pine worms and crushing them to a size of less than 1.5 cm using a sawdust or chip making machine have. This method is low in forest fires because there is no environmental pollution and no dead trees are accumulated in the forest. However, there is a problem that it is easy to drop the tree containing the worms during transportation to crush the infected tree, and the labor and control costs are high.

In order to solve the problems of the prior art as described above, an object of the present invention is to harvest the pine trees and suspicions suspected to be damaged by the nematode disease to extinguish the nematodes in a relatively short time to recycle the nematode diseases and suspicions To provide a way to do this.

It is also an object of the present invention to provide a method capable of minimizing the equipment and manpower required to recycle pine damage and suspicious trees infected with re-nematode disease.

In addition, it is an object of the present invention to improve the method of using wood by reducing the time and cost of wood processing and production of the product, and to improve the ecological environment for the land collecting and fumigation tree, and to facilitate the post-management.

In order to achieve the above object, the present invention provides a method for recycling damage and suspicion caused by a pine re-nematode disease, the method comprising the steps of: (a) harvesting the damage and suspicion suffered by a re-nematode disease; (b) cutting the damage and suspicion into a predetermined size and then inserting it into the heat treatment chamber; And (c) operating the heat treatment chamber to heat the damage wood and the wood at a temperature of 56.5 ° C. or more for 30 minutes or more. It is configured to include, by the heat treatment as described above pine re-nematode provides a recycling method of pine re-nematode disease victims and suspicion, characterized in that pine damage and suspicion can be recycled.

In the present invention, in the step (b), the heat treatment chamber may be configured as a mobile heat treatment chamber so that the heat treatment chamber may be installed in the rear of the vehicle.

In the heat treatment chamber of the present invention, it is preferable that the inside of the heat treatment chamber is maintained at a high temperature by an electric or gas heater.

In addition, the heat treatment chamber of the present invention is preferably provided with a temperature sensor.

In addition, in the present invention, the damage and suspicion introduced into the heat treatment chamber is preferably introduced in the form of a plate.

As described above, the pine re-nematotic disease victims and suspicion recycling method according to the present invention by injecting the pine-damaged trees and suspicious trees affected by re-nematotic diseases in the heat treatment chamber, heat treatment above a certain temperature, a relatively short time and a small cost By extinguishing the nematode, it is effective to recycle pine damage and suspicion caused by the nematode disease.

In addition, as a method of recycling pine worm nematode damage and suspicion according to the present invention, the pine worms and suspicion suffered from re-nematode disease are controlled by a mobile heat treatment chamber, thereby reducing the time, cost, manpower There is an effect that can be minimized.

Hereinafter, with reference to the accompanying drawings will be described in more detail the recycling method of pine nematode disease victims and suspicion according to a preferred embodiment of the present invention.

1 is a block diagram of a method for recycling pine re-nematode disease victims and suspect trees according to the present invention.

Referring to Figure 1, pine tree nematode disease recycling method according to a preferred embodiment of the present invention,

First, logging the damage and suspicion caused by the nematode disease (S10);

Secondly, cutting the damage and suspicion into a predetermined size and then inserting it into the heat treatment chamber (S20); And

Third, operating the heat treatment chamber to heat the wood at a temperature of 56.5 ° C. or more for about 30 minutes or more (S30); It is configured to include.

The heat treatment process for extinguishing the pine re- nematode is made in a heat treatment chamber that can be heated and maintained at a constant temperature, the shape of the heat treatment chamber can be any conventional method capable of maintaining a constant heating and temperature. For example, the bottom portion can be heated like a boiler, it is also possible to directly heat the air inside the heat treatment chamber in the form of a heater, and both electric and gas heating devices are possible. An operation panel for manually or automatically driving the heating device may be installed outside to operate the operation panel to operate the heat treatment chamber.

In addition, a heat detector may be installed in the heat treatment chamber to maintain a uniform temperature (56.5 ° C.). Here, the heat detector is a product capable of sensing a temperature, and sets a predetermined time (about 30 minutes) to automatically shut off the power when the time elapses.

At this time, the reference temperature of 56.5 ° C. and time 30 minutes of the heat treatment are data obtained by repeatedly performing the disappearance of the nematode, and if the temperature and time are kept constant, the temperature increases to 56.5 ° C. or more to the center of the wood and re-nematodes to the pine tree. Can be destroyed.

Therefore, the present invention is characterized in that by the heat treatment as described above is re-neutral parasitic on the pine tree can be recycled to the wood affected by the nematode disease.

Subsequently, the pine re-nematode disease victim and suspicion recycling method of the present invention will be described in more detail as follows.

Firstly, the fallen pine damage and suspicion can be used as it is, or it can be heat treated in the form of a thin plate. In other words, before the heat treatment process it is possible to produce a pine tree in the desired shape, and then heat treatment.

In general, the thickness of the pine board is produced within 15mm, but in some cases even thicker. Pine wood or pine wood in the form of first processed plate is put into the heat treatment chamber to operate the heat treatment chamber to maintain a constant temperature of 56.5 ° C. or higher, and then heat-treat for 30 minutes or more. In some cases, the thicker the wood or plate, the longer the heat treatment time.

As described above, the present invention eliminates all of the pine re-nematodes within a short time by heat treatment, and thus it is not necessary to mobilize huge budget and manpower for chemical treatment or crushing work as in the prior art, thereby reducing the cost of the control work. It can be effective.
