Description

A treatment method for root cutting piles after being damaged by the long forest bark beetle

technical field

The invention relates to the technical field of bark beetle infestation in Changlin, in particular to a method for treating roots and piles after the bark beetle infestation.

technical background

Changlin Beetle belongs to Coleoptera Weevilidae Beetle Subfamily Cuttip Beetle Tribe Forest Beetle. There are three known forest beetles in the world, and most of the host plants are Pinus. At present, the alien pest of the long forest bark beetle has invaded our country and colonized in Yantai, Weihai and Tai'an in Shandong, seriously endangering tree species. Research has found that the long forest bark beetle is extremely harmful. Adults can directly penetrate the soil and invade the roots of trees, which can attack sub-healthy trees in advance and cause death. The insect is highly concealed, and there are no special and easily identifiable hazard characteristics such as obvious insect droppings on the ground, so it is difficult to control. At present, the main problems in controlling the spread of pests are: it is urgent to deal with the damaged piles and roots to prevent the spread of pests, and the long forest beetle is a newly invaded forest pest, and there is still a lack of relevant treatments technology.

Contents of the invention

The purpose of the present invention is to provide a treatment method for cutting roots and piles after being damaged by the long forest bark beetle, which can effectively solve the problems in the background technology.

In order to achieve the above object, the technical scheme that the present invention takes is:

A method for processing root cutting piles after being harmed by the long forest bark beetle, comprising the following steps:

Step 1. Set up fumigation tents: Tents should be set up near the felling sites of logging piles, and the terrain should be open and flat, far away from residential areas.

Step 2, felling root stumps: Use a chainsaw to cut down the infected wood from the base of the trunk, and use a wheeled excavator to hook out the stump stumps.

Step 3. Treatment of root-cutting piles: cut the root-cutting piles into 0.7m-0.8m wood sections, and place the wood sections inside the airtight tent.

Step 4. Check the tent: Check the airtightness and firmness inside the entire tent.

Step 5. Wear a protective mask and set up warning signs: before dosing, wear corresponding gas masks and chemical-resistant gloves in accordance with the aluminum phosphide dosing operation specifications, and set up highly toxic warning signs around 30m away from the dosing site.

Step 6. Add fumigation agent: place a 50ml beaker inside the tent, cut a small opening with a knife in the tent, insert the dosing tube into the inside of the beaker through the small opening, then put the medicine into the beaker through the dosing tube, and quickly pull out the dosing tube after successful dosing. Seal the small opening with waterproof tape.

Step 7. Patrolling the cutting pile processing area: After the successful dosing, it is necessary to arrange special personnel to patrol the processing area to prevent people from entering the processing area by mistake.

Step 8. Ventilate and disperse the poison: 15 days after dosing, wear safety equipment and use a knife to cut the tent to disperse the poison, take out the aluminum phosphide and bury it deep on the spot.

Step 9. Check the fumigation effect: after at least 48 hours of open-air dispersal, take out the cutting piles in the tent to check the effect of killing the long forest bark beetle.

Preferably, extra-thick polypropylene PP color strip cloth is used for the tent cloth in the first step.

Preferably, the height of the felling stake in the step 2 is not less than 1.8m.

Preferably, the treatment method for the poor airtightness of the tent in step 4 is to use waterproof tape for sealing; the weak treatment method is to use sandbags to press the tent support, or fix one end of the steel cable on the tent support, and nail the other end to the tent support. in the soil.

Preferably, the dosage concentration in step six is determined according to the size of the stack according to 9-12g/ ^m3 .

Preferably, the weather conditions when adding aluminum phosphide in the step 6 should be windless or light wind, no rain.

Preferably, the medicament used in the step six is a 56% aluminum phosphide tablet with a specification of 3g per tablet.

The beneficial effects that the present invention has:

1. In the present invention, the root cutting piles can be treated on the spot in the forest, which is efficient and convenient, and can kill the long forest bark beetle in the root cutting piles. The fumigation agent used is economical and convenient, and has strong insecticidal effect. As a result, it solves the blank problem of cutting root cutting pile treatment technology after the damage of the long forest bark beetle.

2. In the present invention, fumigation by 56% aluminum phosphide can not only effectively kill the long forest bark beetle, but also can kill the long beetle beetle. For the trees that are commonly harmed by multiple pests, this method can be used to treat them together. It is worth promoting on a large scale.
