Description

Technical Field

[0001] This utility model relates to the field of insect control equipment technology, specifically to an insect control device for rice seedlings. Background Technology

[0002] The rice seedling stage is a crucial early stage of rice growth, lasting approximately 25-30 days from seed germination to transplanting. Early pest and disease control during this stage is vital for ensuring seedling quality and subsequent yield. During this period, rice is susceptible to pests such as rice planthoppers, rice leaf rollers, and rice stem borers. Traditional control methods primarily rely on chemical pesticides. While these methods can effectively control pests in the short term, long-term, excessive use leads to pesticide resistance in pests, environmental pollution, and excessive pesticide residues, seriously threatening ecosystem security and agricultural product quality.

[0003] To reduce the use of chemical pesticides, physical pest control techniques have been widely adopted. These techniques include the use of insect-proof nets, frequency-vibrating light traps, and sticky traps. These methods not only reduce reliance on chemical pesticides to some extent but are also relatively environmentally friendly. However, existing control methods, such as traditional ozone pest control equipment, suffer from low ozone utilization rates, easily damaging seedlings and causing leaf browning. Furthermore, single insect-proof nets used in the market only achieve a 60%-70% interception rate against rice planthoppers, and their effectiveness only reaches slightly over 85% when combined with frequency-vibrating light traps. Although these technologies can effectively control certain types of pests, they are still insufficient and have certain limitations when addressing the complex and ever-changing pest control needs of rice paddies.

[0004] Therefore, it is particularly urgent to develop a rice seedling pest control device that can comprehensively consider the needs of multiple types of pest control while not causing environmental pollution. Utility Model Content

[0005] The purpose of this invention is to overcome the aforementioned technical difficulties. This invention provides a rice seedling pest control device that can comprehensively consider the needs of multiple types of pest control while not causing environmental pollution.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rice seedling insect control device, comprising a protective frame, the surface of which is covered with an insect-proof net, a solar-powered frequency vibration lamp installed on the top of the protective frame, a yellow sticky insect board and an ozone insect-killing component inside the protective frame, the ozone insect-killing component comprising an ozone generator, an air supply pipe connected to the ozone generator and a porous partition plate; the porous partition plate divides the internal part of the protective frame into an upper cavity and a lower cavity, the upper cavity being a seedling cultivation cavity and the lower cavity being an ozone diffusion cavity, the end of which extends into the ozone diffusion cavity.

[0007] Furthermore, the ozone generator has an ozone output concentration of 0.01-0.1ppm and is equipped with a timed start-stop module, running 1-2 times a day, each time for 10-20 minutes.

[0008] Furthermore, the porous partition plate has multiple pores evenly distributed to diffuse ozone from the ozone diffusion chamber to the soil around the roots of the seedlings.

[0009] Furthermore, the insect-proof netting is coated with a plant-derived repellent layer, which is an extract of azadirachtin or matrine.

[0010] Furthermore, the solar-powered frequency-vibration lamp emits ultraviolet light at a wavelength of 365-400nm.

[0011] Furthermore, the protective frame is also provided with a natural enemy release chamber on its side wall, and the natural enemy release chamber stores Trichogramma egg cards or ladybug adults.

[0012] Furthermore, the protective frame is also equipped with a control terminal, which is connected to the user terminal via a wireless communication module.

[0013] The present invention provides a rice seedling pest control device, which has the following beneficial effects:

[0014] This invention utilizes the synergistic effect of an insect-proof net and a solar-powered frequency-vibration lamp, combined with an ozone insect-killing component to deliver ozone to the roots through controlled-release ozone layering in the rhizosphere. This effectively covers all dimensions of above-ground pest control while killing underground pests without causing browning of seedling leaves, thus increasing the insect-proof coverage rate and improving the seedling survival rate. This invention effectively solves the problem that existing methods of pest control during the rice seedling stage are limited to specific pests and cannot effectively kill underground pests.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. The described embodiments are merely some, not all, of these embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] Example 1

[0020] like Figure 1-2 The present invention provides a rice seedling pest control device, comprising a protective frame 1, which is made of lightweight aluminum alloy frame or high-strength PVC pipe. The surface of the protective frame 1 is covered with a 40-60 mesh insect-proof net 2 with an aperture of 0.25-0.42mm, which can block small pests such as rice planthoppers and rice anchovies. The edges of the net are fixed to the frame by Velcro or magnetic sealing strips to prevent pests from entering through gaps. A solar-powered frequency vibration lamp 3 is installed on the top of the protective frame 1. This application's solar-powered frequency vibration lamp 3 is powered by a 20W solar panel paired with a 12V / 10Ah lithium battery, allowing it to operate continuously for 3-5 days on cloudy or rainy days. It is automatically turned on and off via a light-controlled switch. The solar-powered frequency vibration lamp 3 emits ultraviolet light at a wavelength of 365-400nm, within the ultraviolet-violet band, resulting in a 30-50% higher attraction rate for rice stem borers and rice leaf rollers compared to ordinary white light lamps. The lamp 3 is installed at a 30° angle to expand its illumination range. This application also includes a control terminal on the protective frame 1, which connects to a user terminal via a wireless communication module. The control terminal comprises a main control chip, an integrated temperature and humidity sensor, an insect monitoring camera, and a 4G module. Users can view insect data in real time and remotely adjust ozone concentration and the operating parameters of the solar-powered frequency vibration lamp 3 via an app.

[0021] The protective frame 1 is equipped with a yellow sticky insect board 4 and an ozone insect-killing component. According to the test, the yellow sticky insect board 4 described in this application is 20*30cm in size. When it is hung 10-15cm above the seedlings and spaced 2-3m apart, the trapping efficiency of rice planthoppers and aphids is 70-80%. The porous partition plate 7 has multiple air holes evenly distributed on it, which are used to diffuse the ozone in the ozone diffusion chamber to the soil around the roots of the seedlings. The ozone pest control component includes an ozone generator 5, an air supply pipe 6 connected to the ozone generator 5, and a porous partition plate 7. The porous partition plate 7 is made of PP material with a thickness of 3-5mm and evenly distributed pores with a diameter of 2-3mm, and a pore density of 20-30 pores / ㎡. The porous partition plate 7 divides the interior of the protective frame 1 into an upper cavity 8 and a lower cavity 9. The upper cavity 8 is a seedling cultivation cavity, and the lower cavity 9 is an ozone diffusion cavity. The end of the air supply pipe 6 extends to the ozone diffusion cavity. The porous partition plate 7 is installed 5-8cm away from the seedling roots, so that the ozone can be preferentially diffused into the rhizosphere soil to kill underground pests such as mole crickets and root maggots. This application uses a low-voltage electrolytic ozone generator 5, which is adapted to solar power supply. Its output concentration is precisely controlled to 0.01-0.1ppm and is equipped with a timed start-stop module. It runs 1-2 times a day, each time for 10-20 minutes. The control terminal of this application dynamically adjusts the ozone concentration through a PID algorithm. When the sensor detects a concentration >0.15ppm, it automatically stops. Experimental data shows that the leaf browning rate of traditional ozone spraying is 18-22%. The ozone insecticidal treatment of this application from 3:00 to 5:00 am can kill 85-90% of root maggots, and the root growth of seedlings is increased by 12-15% compared with traditional ozone spraying.

[0022] The applicant conducted a pest control experiment on rice seedlings using the insect control device designed in this application and a traditional insect control device. The traditional insect control device was designed according to CN217722485U. The test results are as follows: the traditional insect control device achieved an insect control coverage rate of 50-60%, a pesticide reduction of 30-40%, and a seedling survival rate of 70-75%; the insect control device designed in this application achieved an insect control coverage rate of 85-90%, a pesticide reduction of 80-90%, and a seedling survival rate of 88-92%. It can be seen that the insect control device designed in this application has achieved significant progress in pest control effect on rice seedlings compared with the traditional insect control device.

[0023] Example 2

[0024] Based on the above embodiments, this embodiment aims to further improve the insect-proofing effect of the insect-proof net 2. The applicant applies a plant-derived repellent layer to the surface of the insect-proof net 2 using electrostatic spraying. The plant-derived repellent layer is azadirachtin or matrine extract. This application sprays a 0.3-0.5% azadirachtin or a 1-2% matrine solution onto the surface of the insect-proof net 2 to form a long-lasting repellent layer. The plant-derived repellent layer of this application can also repel migratory pests that escape from the insect-proof net 2, forming a double interception. Experiments show that compared with the insect-proof net 2 without a coating, the plant-derived repellent layer applied to the surface of the insect-proof net 2 can increase the repellency rate of rice planthoppers by 40-60%, and the effective period can reach 15-20 days. By combining the plant-derived repellent layer with the insect-proof net, this application can effectively compensate for the escape loopholes of migratory pests caused by physical barriers.

[0025] Example 3

[0026] Based on the above embodiments, in order to further improve the protection against rice seedling pests, this application also provides a natural enemy release chamber 10 on the side wall of the protective frame 1, and a controllable sliding door is opened on the side wall of the natural enemy release chamber 10, with an opening degree adjustable from 0-10mm. It contains slow-release Trichogramma wasp egg cards (each card contains 2000-3000 eggs) or ladybug adults (20-30 per chamber). The natural enemy release chamber 10 is activated 2 hours after the ozone pest control ends. The egg mass of rice leaf roller is identified by the insect camera. Based on the egg mass detection accuracy of the image equipment ≥90%, the opening degree of the sliding door is automatically adjusted to 5mm, and Trichogramma wasps are released in 3 batches with an interval of 72±2 hours between each batch to avoid ozone residue affecting the activity of the natural enemy. The parasitism rate can reach 60-75% after a 7-day survey after the completion of the three batches of release.

[0027] Therefore, it can be seen that the insect-proof net and solar frequency vibration lamp iron tube of this application cover pests at different activity levels. Combined with the ozone insect-killing component, ozone is delivered to the roots through layered controlled release of ozone in the rhizosphere. This can effectively cover all dimensions of pest control on the ground while killing underground pests without causing browning of seedling leaves. In addition, the release sequence of natural enemies set in this application complements the layered controlled release of ozone in the rhizosphere, improving the pest control coverage rate and further improving the seedling survival rate of rice. This effectively solves the problem that the existing pest control methods for rice seedlings are singular, only targeting specific pests and unable to effectively kill underground pests.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
