Description

Technical Field

[0001] The invention relates to the field of forestry pest control, and in particular to an intelligent ecological pest control cover for controlling pine wood nematode disease. Background Art

[0002] Pine wood nematode ( Bursaphelenchus xylophilus ) is a common pine parasite. It spreads through the pine beetle ( Monochamus alternatus ) and other vector insects. The needles of infected pine trees turn yellow-brown or reddish-brown, and the whole tree dries up and dies, eventually rotting. This was introduced from the United States to Japan, and then from Japan to China and South Korea in the 1980s. China first discovered it in Nanjing Sun Yat-sen Mausoleum in 1982, and then it became a disaster in 14 provinces, autonomous regions and municipalities including Jiangsu and Anhui, killing more than 500 million pine trees and destroying more than 5 million mu of pine forest. It is one of the most harmful alien invasive species in China. According to a rough estimate by relevant national departments in 2019, the number of diseased and dead pine trees in China in 2019 alone could reach 5 billion.

[0003] Pine beetle is the main carrier of pine wood nematode, and reducing its insect population density is an important means of preventing and controlling pine wood nematode disease. In order to effectively curb the spread of the epidemic, blocking the adult pine beetle has become a top priority. The anti-escape cover of the present invention can not only prevent the adult pine beetle from spreading outside the infected wood or infected pile, but also can kill the longhorn beetle in a targeted manner, quickly destroy the environment where the longhorn beetle larvae live, and effectively restore the ecology. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an intelligent ecological epidemic prevention cover for preventing and controlling pine wood nematode disease.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is: an intelligent ecological epidemic prevention cover for preventing and controlling pine wood nematode disease, characterized in that: the topmost layer of the intelligent ecological epidemic prevention cover is a first PVC layer, a steel mesh is provided on the lower surface of the first PVC layer, a second PVC layer is provided under the steel mesh, the first PVC layer, the steel mesh and the second PVC layer are integrally formed by UV adhesive bonding and pressing, a film-forming agent layer for wrapping drugs is provided on the lower surface of the second PVC layer, a seed bag is provided under the film-forming agent layer, a satellite positioning chip, a solar panel and a QR code label are provided on the upper surface of the first PVC layer, the solar panel supplies power for the satellite positioning chip, and the QR code label contains management information of the ecological epidemic prevention cover, and the user can directly access the management information after scanning the QR code with a mobile phone.

[0006] Furthermore, the seed bag is a non-woven fabric layer that wraps the seeds.

[0007] Furthermore, the satellite positioning chip is a GPS positioning chip or a Beidou positioning chip.

[0008] Furthermore, the drug includes a highly efficient cyhalothrin microcapsule suspension, Bacillus thuringiensis and decomposing bacteria, and the Bacillus thuringiensis and decomposing bacteria are adsorbed on 60-mesh diatomaceous earth.

[0009] Furthermore, the mass ratio of the highly effective chlorfenapyr microcapsule suspension, Bacillus thuringiensis and decomposing bacteria is 8:1:1, and the decomposing bacteria includes the following components by weight percentage: 20% Bacillus subtilis, 25% Bacillus megaterium, 30% Trichoderma harzianum, and 25% Trichoderma viride.

[0010] Furthermore, the film-forming agent layer is obtained by mixing the film-forming agent and the drug, spraying the mixture evenly on the lower surface of the second PVC layer, and then heating and curing the mixture.

[0011] Another technical solution of the present invention is: a production process of an intelligent ecological quarantine cover for preventing and controlling pine wood nematode disease, characterized in that it comprises the following steps:

[0012] 1) Ultrasonic degreasing: Place the wire mesh in acetone for ultrasonic degreasing, and then rinse it with deionized water;

[0013] 2) Pickling: Place the wire mesh in a pickling tank, use nitric acid as the pickling liquid for pickling, and then rinse with deionized water;

[0014] 3) Phosphating: Place the pickled wire mesh in a phosphating tank, use phosphate for phosphating, and then rinse with deionized water;

[0015] 4) Drying: Dry the phosphated steel wire mesh;

[0016] 5) Glue spraying and laminating: spray UV glue on the upper and lower surfaces of the wire mesh, then stick the first PVC layer on the upper surface and the second PVC layer on the lower surface;

[0017] 6) Saturation pressure treatment: The first PVC layer, the steel wire mesh and the second PVC layer are subjected to saturation pressure treatment;

[0018] 7) Spraying film-forming agent: Mix the film-forming agent SY-202 for seed coating with the drug, so that the drug is completely wrapped by the film-forming agent, and then evenly spray the film-forming agent wrapped with the drug on the lower surface of the second PVC layer, and obtain the film-forming agent layer after heating and curing;

[0019] 8) Seed bag preparation: Wrap the seeds with non-woven fabric to make a seed bag, and then bond it under the film-forming agent layer with UV glue;

[0020] 9) The satellite positioning chip, solar panel and QR code label are bonded to the upper surface of the first PVC layer by UV glue to make a smart ecological epidemic prevention cover. The QR code label contains the management information of the ecological epidemic prevention cover, and the user can directly access the management information after scanning the QR code with a mobile phone.

[0021] Beneficial effects of the present invention:

[0022] The first PVC layer of the intelligent ecological epidemic prevention cover of the present invention covers the pine wood nematode diseased wood or felled pile outward, trapping the pine beetle inside. The first PVC layer and the second PVC layer can maintain the temperature of the diseased wood and the pile, extend the effective period of the drug in the film-forming agent layer, and maintain the activity of the mature bacteria; the wire mesh can prevent the pine beetle from biting the epidemic prevention cover and going out.

[0023] The film-forming agent layer is easily decomposed when it comes into contact with water, and can slowly release the drug into the infected trees and stumps, prolonging the insecticidal time of the drug and increasing the insecticidal rate. After the insecticidal treatment, the infected trees or stumps will decay faster under the action of the decomposing bacteria, and the grass seeds and spore powder of Matsutake mushroom in the seed bag will grow in situ, greening the environment.

[0024] The satellite positioning chip makes it easy to query the location of the ecological epidemic prevention cover. The QR code label contains the management information of the ecological epidemic prevention cover (for example: construction time of the construction unit, inspection time of the grassroots management department, inspection time of the superior management department, etc.). The user can directly access the management information after scanning the QR code with his mobile phone. BRIEF DESCRIPTION OF THE DRAWINGS
