Description

A protective film for preventing and controlling pests of diseased tree stumps

technical field

The utility model relates to the field of prevention and control of forest diseases and insect pests, in particular to a protective film for preventing and controlling diseases and insect pests of diseased tree felling piles.

Background technique

In recent years, harmful organisms such as pine wood nematode, longhorn beetle, and pine-necked elephant are the main pests that harm pine trees, especially pine wood nematode is a devastating pest to pine trees, and pine wood nematode disease of pine trees has a rapid onset and death rate. The spread spreads rapidly, and monitoring and control is difficult. Once a pine tree is infected, it can die within 40 days at the earliest. It is a very dangerous quarantine object. In recent years, the disease has spread rapidly in my country, and the danger has become increasingly serious, posing a very serious threat to forestry production and ecological construction. In order to ensure forestry safety, it is very important to do a good job in the prevention and control of pine wood nematode disease.

At present, pine wood nematode disease control in endemic areas is mainly done by felling and clearing diseased wood, and the leftover stumps are the most difficult entity to treat in the treatment of pine wood nematode disease. It is an important source of infection of pine wood nematodes. In the prior art, drugs are generally used to kill pine wood nematodes or long beetles and other pests. For example, 16% chrysophila, pyrethroid and other agents are mixed with water or other solvents in a certain proportion. The medicament formed; although the effective medicament can enter the surface of the pile body or the pile hole that has been driven, due to the volatility of the medicine, the drug effect of the medicine cannot be brought into play well.

In the medicine removal of diseased tree stumps, the existing technology generally adopts the operation in the national standard operation specification, and the stumps are sealed with a plastic film binding sealing method. Disadvantages such as tightness, air leakage and high labor costs are common, resulting in the medicine not being able to contact the beetle or pine wood nematode and other insects well, so that the killing is not complete, and because the hardness of the film is not enough, some residual pests often break the membrane and die. Hazards continue, resulting in poor pest removal effect of sick tree stumps. Therefore, the utility model provides a simple and effective protective film for diseased tree felling piles to improve the effect of diseased tree felling piles.

Utility model content

In order to solve the problem in the prior art that the pest removal effect of diseased tree felling piles is poor, the utility model provides a protective film for preventing and controlling diseases and insect pests of diseased tree felling piles.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A protective film for preventing and controlling diseases and insect pests of diseased tree stumps. The protective film includes a first layer of protective film covering the diseased tree stumps. The protective film is formed by brushing or spraying film-forming emulsion on the diseased tree stumps.

In order to solve the problem of poor insecticidal effect due to volatilization of medicines in the prior art by using plastic film binding and sealing method, the utility model provides a simple and effective protective film for preventing and controlling diseased tree felling piles, diseases and insect pests to improve the efficiency of diseased tree felling piles. The protective film has changed the conventional sealing method of plastic film binding. It is formed by applying or spraying the film-forming emulsion on the stump of the diseased tree. The first layer of protective film formed can seal the insecticide well. In the residual pile, the efficacy of insecticides can be fully exerted; the protective film is formed quickly and degraded after three years, without pollution, and the ecological environment is protected; it is easy to operate and saves labor costs.

Before the formation of the first layer of protective film, the diseased tree stumps can be perforated according to needs, and the insecticides can be sprayed on the treated stumps. The hole is covered, and the film-forming emulsion is smeared or sprayed on the diseased tree stump after the covering treatment, and the film-forming emulsion quickly forms the first layer of protective film described in the utility model.

Preferably, in order to increase the effect of the protective film, the protective film also includes a second protective film, the second protective film covers the surface of the first protective film, and the second protective film is protected by a film-forming emulsion on the first layer. It is made by brushing or spraying on the film.

Preferably, the protective film also includes a third protective film, the third protective film can be covered on the surface of the first protective film, or can be covered on the surface of the second protective film, the third protective film is made of mineral powder The particles are painted or sprayed on the first or second layer of protective film; the third layer of protective film can be sprayed with mineral powder on the first or second layer of protective film with a special sandblasting tool. The particles are evenly sprinkled and thrown to form a protective film with higher hardness; the mineral powder can choose 80-120 mesh quartz powder.

The utility model provides a protective film for preventing and controlling diseased tree cutting piles. The protective film includes a first layer of protective film covering the sick tree cutting piles. The first layer of protective film is coated on the diseased tree cutting piles by film-forming emulsion. Brushed or sprinkled. The protective film has good sealing performance, can effectively prevent the volatilization of killing drugs, and improves the effectiveness of drugs against insect pests such as longhorns or pine wood nematodes; the protective film has no pollution, protects the ecological environment, is easy to operate, and has high practicability. Forestry pest control has played a very good auxiliary role.

detailed description

The utility model aims to provide a protective film for preventing and controlling pests of diseased tree felling piles, so as to solve the problem of poor pest removal effect of diseased tree felling piles in the prior art.

In order to enable those skilled in the art to better understand the utility model, the utility model will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

A protective film for preventing and controlling diseased tree stump diseases and insect pests, the protective film includes a first layer of protective film 1 covered on the sick tree stump A, and the protective film is formed after the film-forming emulsion is painted or sprayed on the sick tree stump of.

Before the formation of the first layer of protective film, the diseased tree stumps can be perforated according to needs, and the insecticides can be sprayed on the treated stumps. The holes are covered, and the film-forming emulsion is smeared or sprayed on the diseased tree stump after the covering treatment, and the film-forming emulsion quickly forms the first layer of protective film 1 described in the utility model.
