[0033] Referring to Figures 1 to 3, an agricultural drone equipped with a blue-red LED plant germicidal lamp according to an embodiment of the present invention includes: a drone body, a camera 200, and a plant germicidal lamp 300.

[0034] Referring to Figures 1, 2, and 3, the unmanned aerial vehicle (UAV) includes a body 110, landing gear 120, and arms 130. Two landing gear 120s are arranged laterally, with their upper ends connected to the body 110. The two landing gear 120s are symmetrically arranged about the central axis of the body 110. Multiple arms 130 are arranged around the body 110. One end of each arm 130 is connected to the body 110, and the other end is connected to a rotary actuator and a propeller 140. The rotary actuator can be a motor, which is connected to the propeller 140 to drive its rotation. The rotation of the propeller 140, driven by the rotary actuator, propels the body 110 into flight.

[0035] Referring to Figures 1, 2, and 3, the camera 200 is connected to the drone to acquire image data of the surrounding environment. This allows the user to capture images or videos of the surrounding environment, thereby identifying the type of crops and adjusting the operating mode of the plant germicidal lamp 300, such as adjusting its intensity or light distribution. The user can plan the drone's flight path based on the surrounding environment and crop distribution to ensure both flight safety and efficient crop sterilization.

[0036] Referring to Figures 1, 2, and 3, specifically, the plant germicidal lamp 300 is connected to the drone body and is used to irradiate the plants below the drone body's flight path. When the drone body flies along the preset flight path, the plant germicidal lamp 300 operates, directly shining light onto the surface of the plants below the drone body to achieve the function of preventing and controlling pests and diseases.

[0037] Referring to Figures 1, 2, and 3, compared to traditional agricultural equipment that controls pests and diseases by spraying pesticides, the agricultural drone equipped with blue and red LED plant germicidal lamps provided in this embodiment of the invention regulates plant growth and development through light and modulates the plant's immune regulation process, which has a significant inhibitory effect on pathogens that can cause plant diseases, thereby reducing or even eliminating the use of pesticides. While achieving pest and disease control, it leaves no environmental pollution residue and is safer and more reliable.

[0038] Understandably, the study "The Effects of Light on the Biological Characteristics and Enzyme Activities of Two Ginseng Pathogens" (DOI: 10.27163 / d.cnki.gjlnu.2021.000730) showed that light quality can regulate the activity of antioxidant enzymes in ginseng leaves. The antioxidant enzyme activities under blue and red light treatments were higher than those in the control group and the yellow light group before infection. After pathogen infection, the leaf lesions under blue and red light were smaller and the disease severity was milder. This proves that blue and red light can better regulate the ginseng leaf defense system, improve ginseng disease resistance, and reduce the occurrence of diseases.

[0039] The study "Effects of Different Light Qualities on Extracellular Degrading Enzyme Activity and Disease Occurrence of Ginseng Black Spot Fungus" (DOI: 10.13327 / j.jjlau.2021.1514) showed that red light treatment had a significant inhibitory effect on the occurrence of ginseng black spot disease, followed by blue light; under white light treatment, the disease was the most severe.

[0040] The study, titled "The Effects of LED Light Quality on the Occurrence of White Rust and Related Enzyme Activities in Water Spinach" (Liu Yanan, Lin Biying, Shen Baoying, et al. Subtropical Agricultural Research, 2019, 15(3):189-193), showed that blue light can significantly increase the activity of PAL (Phenylalanine Ammonia Lyase) in the leaves of water spinach and the activity of SOD (Superoxide Dismutase) in various parts of the stem, and significantly reduce the incidence of white rust in water spinach, thus delaying the deterioration of the disease.

[0041] The study, titled "The Effects of Different LED Red and Blue Light Combinations on the Defense Mechanism of Tomato Gray Mold" (Chen Yanqi, Zhang Tao, Liu Yongpeng, Ren Zijun, Yan Yingjie. China Vegetables and Melons, 2023, Vol. 36, No. 4, pp. 89-95, 1673-2871), showed that different ratios of red and blue light components had a certain inhibitory effect on the infection of tomato gray mold, with the highest inhibition rate of lesions observed under the (red:blue 5:1) treatment.

[0042] The study "Effects of Blue / Red Light and Its Receptors on Resistance to Late Blight in Tobacco Benzoin / Potato" (DOI: 10.27158 / d.cnki.ghznu.2023.001926) showed that late blight pathogens cultured in white light supplemented with blue light (WBL, 122.603 μmol / m² / s) and white light supplemented with red light (WRL, 63.626 μmol / m² / s) exhibited significantly reduced mycelial growth, sporulation, and pathogenicity compared to the control group under normal white light (NWL, 79.292 μmol / m² / s). This indicates that blue and red light have an inhibitory effect on the growth and pathogenicity of late blight pathogens.

[0043] Referring to Figures 1, 2, and 3, it is evident that red and blue light inhibit the growth of various common plant pathogens. Controlling the light intensity at an appropriate level can significantly suppress pathogen growth. Therefore, this plant germicidal lamp 300 includes a blue light lamp and a red light lamp. The blue light lamp produces blue light and projects it onto the plant surface, while the red light lamp produces red light and projects it onto the plant surface. Specifically, the blue and red light lamps can be LED lights.

[0044] Referring to Figures 1, 2, and 3, blue and red light are the most important light sources for plant photosynthesis. Enhancing the irradiation of blue and red light promotes plant growth and inhibits the occurrence of pests and diseases. The plant germicidal lamp 300 of the agricultural drone equipped with blue and red LED plant germicidal lamps provided in this embodiment of the invention can effectively regulate plant growth and development and modulate the plant's immune regulation process by irradiating red and blue light. It has a significant inhibitory effect on pathogens that can cause plant diseases, leaves no pollution residue in the environment, and is more safe and reliable.

[0045] Referring to Figures 1, 2, and 3, it can be understood that multiple blue and red lights are provided. This agricultural drone equipped with blue and red LED plant germicidal lamps can change the ratio of red and blue light according to the type of plant and the types of pests and diseases that are susceptible to it, thereby improving the targeting of different plants and types of pests and diseases, so as to improve the inhibitory effect on the pathogens of specific plant diseases, that is, to improve the sterilization effect.

[0046] Referring to Figures 1, 2, and 3, it can be understood that the wavelength of the blue light emitted by the blue light lamp is 430-460nm. The 430-460nm blue light achieves green control by targeting and inhibiting the metabolism of pathogens, interfering with the behavior of pests, and activating plant immunity. It has the advantages of no chemical residue and strong environmental compatibility.

[0047] Referring to Figures 1, 2, and 3, specifically, the wavelength of the red light emitted by the red lamp is 640-660nm. The 640-660nm red light achieves green control by directly inhibiting pathogen development, interfering with pest behavior, and activating plant immunity. It has the advantages of no chemical residue and strong environmental compatibility.

[0048] Referring to Figures 1, 2, and 3, the agricultural drone equipped with blue and red LED plant germicidal lamps can further inhibit pathogen development and interfere with pest behavior by combining specific wavelengths of red and blue light, thereby achieving a better effect in preventing and controlling pests and diseases.

[0049] Referring to Figures 1, 2, and 3, it can be understood that the plant germicidal lamp 300 includes a lamp panel, the upper end of which is connected to the lower end of the body 110. Multiple blue lamps and multiple red lamps are connected to the lower end of the lamp panel. The light emission direction of the blue lamps and red lamps is set downwards, so that the blue light and red light are directly shone on the plant surface from top to bottom for sterilization.

[0050] Referring to Figures 1, 2, and 3, this agricultural drone equipped with blue and red LED plant germicidal lamps can change the ratio of red to blue light by controlling the number of red and blue lights that are turned on and off, depending on the type of plant being targeted and the types of pests and diseases that are susceptible to them. This allows for targeted pest and disease control and improves the control effect.

[0051] Referring to Figures 1, 2, and 3, it can be understood that the lamp panel is detachably connected to the body 110. Depending on the type of plant and the types of pests and diseases that are susceptible to infection, the user can change the ratio of red light to blue light by replacing the lamp panel. This can achieve targeted inhibition of pathogen metabolism, interference with pest behavior, and activation of plant immunity, thereby achieving green pest control and improving the applicability of the agricultural drone equipped with blue and red LED plant germicidal lamps to different plant species.

[0052] Referring to Figures 1, 2, and 3, it can be understood that the agricultural drone equipped with blue and red LED plant germicidal lamps also includes a illuminance meter 420 for measuring the light intensity of the surrounding environment. The blue light is configured to adjust its operating state according to the detection value of the illuminance meter 420, and the red light is configured to adjust its operating state according to the detection value of the illuminance meter 420.

[0053] Referring to Figures 1, 2, and 3, considering that the light intensity of the surrounding environment has a significant impact on the irradiation effect of the red and blue light of the plant germicidal lamp 300, the agricultural drone equipped with the blue and red LED plant germicidal lamp is equipped with a illuminance meter 420. When the illuminance of the surrounding environment detected by the illuminance meter 420 exceeds a first set value, the agricultural drone equipped with the blue and red LED plant germicidal lamp can reduce the power of the red or blue light lamp, thereby reducing the intensity of the red or blue light and avoiding the problem of light saturation or light damage caused by superposition with high ambient light.

[0054] Referring to Figures 1, 2, and 3, when the ambient light level detected by the illuminance meter 420 is lower than the second set value, the agricultural drone equipped with blue and red LED plant germicidal lamps can increase the power of the red or blue light lamps to increase the intensity of the red or blue light, and then supplement the red or blue light to prevent and control diseases at night or during low light periods.

[0055] Referring to Figures 1, 2, and 3, the agricultural drone equipped with blue and red LED plant germicidal lamps can control the working state of the red or blue lamps based on the detection value of the illuminance meter 420, which helps to save energy and improve the drone's endurance.

[0056] Referring to Figures 1, 2, and 3, it can be understood that the agricultural drone equipped with blue and red LED plant sterilization lamps also includes a crossbeam 410 and two tripods 120, which are spaced apart from each other. The two ends of the crossbeam 410 are connected to the two tripods 120 respectively. A light meter 420 is connected to the crossbeam 410, which enables the light meter 420 to obtain the light intensity of the surrounding environment, so as to ensure the accuracy of red and blue light regulation and improve the control effect of plant diseases and pests.

[0057] Referring to Figures 1, 2, and 3, it can be understood that the agricultural drone equipped with blue-red LED plant germicidal lamps also includes a battery and a photovoltaic panel 500 connected to the upper part of the body 110. The photovoltaic panel 500 can convert light energy into electrical energy and power the plant germicidal lamp 300 and the rotary driver. Through the combined power supply of the battery and the photovoltaic panel 500, the power supply of the plant germicidal lamp 300 and the rotary driver of the agricultural drone equipped with blue-red LED plant germicidal lamps can be more stable and reliable, thereby improving the endurance and thus improving the sterilization efficiency of plants.

[0058] Referring to Figures 1, 2, and 3, the agricultural drone equipped with a blue-red LED plant germicidal lamp can use a lightweight, high-efficiency, new type of thin solar panel as the photovoltaic panel 500, which can solve the power consumption problem of the blue-red LED plant germicidal lamp 300 and improve the endurance of the agricultural drone equipped with the blue-red LED plant germicidal lamp.

[0059] Referring to Figures 1, 2, and 3, it can be understood that the agricultural drone equipped with blue and red LED plant germicidal lamps also includes a barometric altimeter connected to the drone body. The barometric altimeter is used to measure the flight altitude of the drone body. Based on the detected flight altitude, the agricultural drone equipped with blue and red LED plant germicidal lamps can control the irradiation range of the plant germicidal lamps 300, thereby improving the effect of controlling plant diseases and pests.

[0060] Referring to Figures 1, 2, and 3, the agricultural drone equipped with a blue and red LED plant germicidal lamp also includes a GPS module connected to the drone body. The GPS module is used to calibrate the real-time position of the drone body and can determine the flight speed of the drone body. By controlling the flight speed, in conjunction with the operation of the plant germicidal lamp 300, the illumination time of the plant by the plant germicidal lamp 300 can be controlled, thereby improving the effect of plant pest and disease control.

[0061] Referring to Figures 1, 2, and 3, the agricultural drone equipped with blue and red LED plant germicidal lamps also includes an inertial measurement module.
