Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of agriculture and relates to an insecticidal device for rice planting management and a using method thereof. Background Art
[0002] Pest control is required at different stages of rice planting, mainly in biochemical ways. Physical pest control is less used because of its high cost (management cost and equipment cost), low safety, and unobvious effect. Of course, another important reason is that physical methods generally can only deal with pests after eclosion, while there are many types of rice pests and they also cause harm before eclosion.
[0003] The present solution provides a physical insecticidal method, which mainly deals with pests after eclosion, such as rice planthoppers and rice skipper butterflies. The existing insecticidal methods are generally light-induced electrocution type, and their defects are obvious, especially their practical value is small in the process of rice pest control. First, most periods of paddy fields are in wet and water environments, and the electrocution insecticidal method has potential safety hazards and risks of grounding failure, and both reliability and safety are not conducive to management. Second, the structure is complex and the cost is high. Third, most existing insecticidal devices are mesh structures, which require frequent cleaning of insect corpses, with high practical costs, and the insecticidal effect is significantly affected over time. Summary of the Invention
[0004] The first object of the present invention is to provide an insecticidal device for rice planting management in view of the above problems existing in the prior art. The technical problem to be solved by the present invention is to optimize the structure and eliminate the need for cleaning insect corpses.
[0005] The object of the present invention can be achieved by the following technical solutions: An insecticidal device for rice planting management, characterized in that it includes a box cylinder with an open bottom end, a battery installation box located inside the box cylinder, a light source located at the bottom of the battery installation box, and two insect attracting units symmetrically arranged on both sides of the light source. The insect attracting unit includes an insect attracting entrance, a first reflector, and a second reflector on the side wall of the upper part of the box cylinder. A light guiding channel connecting the insect attracting entrance and the lower opening of the box cylinder is formed between the side wall of the battery installation box and the side wall of the box cylinder. The first reflector is parallel to the second reflector, and the light emitted by the light source can be guided to the outside of the insect attracting entrance through the first reflector and the second reflector in sequence. A throat located below the light source is formed between the two first reflectors.
[0006] Furthermore, the lower part of the battery installation box is a wedge shape with the large end facing up, and a plurality of protection plates are suspended on the wedge-shaped surface of the battery installation box. The upper end of the protection plate is connected to the side wall surface of the battery installation box, and the lower end of the protection plate hangs freely.
[0007] Further, a hollowed-out part is provided on the side wall of the box cylinder below the first reflector, and the hollowed-out part is composed of several small holes formed on the side wall of the box cylinder to block the passage of pests.
[0008] Further, the mirror surface of the first reflector forms an inclination angle of 30 to 60° with the horizontal plane.
[0009] Further, a storage battery for supplying power to the light source is arranged in the battery installation box, and a photovoltaic panel capable of supplying power to the storage battery is provided on the top of the box cylinder.
[0010] Further, the first reflector is a detachable part.
[0011] Further, there is a gap between adjacent protection plates, and the protection plates are made of transparent plastic material.
[0012] Further, insertion piles capable of vertically fixing the box body in the soil are arranged at the bottom of the box cylinder.
[0013] This solution utilizes the "periscope" principle. The light source is arranged in the middle and lower part of the box cylinder, so that the emerging pests can be induced into the light guide channel. Under the phototaxis characteristic, most of the pests entering the light guide channel tend to contact the light source or continue to move downward to enter the area below the two first reflectors. The pests located below the two first reflectors are trapped because they are blocked from moving upward and the lower space is spacious. Due to frequent contact with water, mud, and mutual harm among high-density pests, the pests below the first reflector are collected in the paddy field at the lower part of the box cylinder, that is, the pest corpses do not need to be cleaned.
[0014] As a detailed explanation, in terms of insect trapping: after the pests enter through the insect trapping entrance, they trace back and enter the light guide channel. The suspended protection plates can negatively affect the pests from perching on the protection plates. After entering the area below the light source, the protection plates play a "return prevention" role, restricting the pests from moving upward to a certain extent. The shaking of the protection plates comes from the touch of the pests and the air flow entering the box cylinder from the insect trapping entrance. The shaking protection plates drive and interfere with the pests, causing some of them to fall near the throat and then enter the area below the first reflector and be trapped; the air flow enters from the insect trapping entrance and is discharged from the hollowed-out part at the bottom of the box cylinder, which can also increase the probability of the pests moving along the set path to a certain extent, and can also increase the shaking frequency of the protection plates, accelerating the downward movement of the pests and making the pests shorten their stay time in the light guide channel as much as possible; in terms of pest cleaning: since the pests are directly scattered in the paddy field after being trapped, there is no need to carry out cumbersome cleaning on them, and only the placement position needs to be changed regularly; in addition to dispersing the pests from perching, the protection plates can also protect the light source to a certain extent, preventing the pests from contacting the light source when moving downward and polluting the light source; when the first reflector is polluted, there is still some light that can be externally guided in the direction of the insect trapping entrance through the second reflector.
[0015] According to needs, this insecticidal device can be used when there is water in the field or when there is no water in the field. When used in the presence of water in the field, the insecticidal time after the pests are trapped is shorter, the probability of their return is smaller, the insecticidal effect is better, and the maintenance period is longer. Additionally, if it is a paddy field, the part below the throat will also form a reflection on the water surface due to light, increasing the probability of pests moving downward. It is equivalent to the inside of the box cylinder below the light source being relatively bright, and the phototactic activity of the pests below the first reflector is more frequent, enabling the pests to die from fatigue and mutual collision more quickly.
[0016] The second object of the present invention is to provide a method for using the above insecticidal device in rice planting management.
[0017] Insert the insertion pile at the bottom of the box cylinder into the soil of the paddy field or seedling field, ensuring that the bottom opening of the box cylinder is blocked by soil or water, and some small holes in the hollow part are above the soil or water surface. One of the insect attracting entrances should preferably face the wind direction; regularly change the placement position of the box cylinder in the field.
[0018] This method is the method for achieving the optimal effect of the insecticidal device. Even if this method is not followed, the insecticidal function can still be achieved. For example, if the insertion position of the box cylinder is deeper or shallower, there may be situations of insect attracting effect and partial escape of pests, but it does not affect the overall feasibility.

DETAILED DESCRIPTION OF THE INVENTION
[0023] The following are specific embodiments of the present invention in combination with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0024] As Figure 1 、 Figure 2 and Figure 3The insecticidal device shown includes a box barrel 1 with an open bottom end, a battery installation box 2 located inside the box barrel 1, a light source at the bottom of the battery installation box 2, and two insect attracting units symmetrically arranged on both sides of the light source. The insect attracting unit includes an insect attracting entrance 3, a first reflector 4, and a second reflector 5 on the side wall of the upper part of the box barrel 1. A light guiding channel 6 that connects the insect attracting entrance 3 and the lower opening of the box barrel 1 is formed between the side wall of the battery installation box 2 and the side wall of the box barrel 1. The first reflector 4 and the second reflector 5 are parallel, and the light emitted by the light source can be guided to the outside of the insect attracting entrance 3 through the first reflector 4 and the second reflector 5 in sequence. A throat 7 located below the light source is formed between the two first reflectors 4.
[0025] The lower part of the battery installation box 2 is a wedge shape with the large end facing up. A number of protection plates 8 are suspended on the wedge-shaped surface of the battery installation box 2. The upper end of the protection plate 8 is connected to the side wall surface of the battery installation box 2, and the lower end of the protection plate 8 hangs freely.
[0026] The side wall of the box barrel 1 has a hollowed-out part 9 located below the first reflector 4. The hollowed-out part 9 is composed of a number of small holes opened on the side wall of the box barrel 1 to prevent pests from passing through.
[0027] The mirror surface of the first reflector 4 forms an inclination angle of 30 to 60° with the horizontal plane.
[0028] A storage battery 10 for supplying power to the light source is arranged inside the battery installation box 2, and a photovoltaic panel 11 capable of supplying power to the storage battery 10 is provided at the top of the box barrel 1.
[0029] The first reflector 4 is a detachable part.
[0030] There is a gap between adjacent protection plates 8, and the protection plate 8 is made of transparent plastic material.
[0031] Insertion piles 12 capable of vertically fixing the box body in the soil are arranged at the bottom of the box barrel 1.
[0032] This solution uses the "periscope" principle. The light source is set in the middle and lower part of the box barrel 1, so that the emerging pests can be induced into the light guiding channel 6. Under the phototactic characteristic, most of the pests entering the light guiding channel 6 tend to contact the light source or continue to move downward to enter under the two first reflectors 4 from the throat 7. The pests located under the two first reflectors 4 are imprisoned because they are blocked from moving upward and the lower space is spacious. Due to frequent contact with water, mud, and mutual harm among high-density pests, the pests under the first reflector 4 are collected in the paddy field at the lower part of the box barrel 1, that is, the cleaning of pest corpses is avoided.
[0033] For a more detailed explanation, in terms of attracting insects: after pests enter through the insect attracting entrance 3, they trace back and enter the light guiding channel 6. The suspended protection plate 8 can negatively affect the pests' resting on the protection plate 8. After entering the area below the light source, the protection plate 8 plays a "preventing return" role, restricting the upward movement of pests to a certain extent. The shaking of the protection plate 8 comes from the pests' touching and also from the air flow entering the box barrel 1 through the insect attracting entrance 3. The shaking protection plate 8 drives and interferes with the pests, causing some of them to fall near the throat 7 and then enter the area below the first reflector 4 and be trapped; The air flow enters through the insect attracting entrance 3 and is discharged from the hollow part 9 at the bottom of the box barrel 1, which can also increase the probability of pests moving along the set path to a certain extent, and can also increase the shaking frequency of the protection plate 8, accelerating the downward movement of pests and minimizing the staying time of pests in the light guiding channel 6; In terms of pest cleaning: since the pests are directly scattered in the paddy field after being trapped, there is no need to conduct cumbersome cleaning on them, and only the placement position needs to be changed regularly; In addition to dispersing the pests' stay, the protection plate 8 can also protect the light source to a certain extent, preventing the pests from contacting the light source when moving downward and polluting the light source; When the first reflector 4 is contaminated, some light can still be guided outward towards the insect attracting entrance 3 through the second reflector 5.
[0034] As needed, this insecticidal device can be used when there is water in the field or when there is no water in the field. When there is water in the field, the time for killing pests is shorter, the probability of return is smaller, the insecticidal effect is better, and the maintenance period is longer; In addition, if there is a paddy field, the area below the throat 7 will also form a reflection on the water surface due to the light, increasing the probability of pests moving downward. It is equivalent to that the inside of the box barrel 1 below the light source is also relatively bright, and the phototactic activity of pests below the first reflector 4 is more frequent, and the pests can die from fatigue and collide with each other more quickly.
[0035] During use, insert the insertion pile 12 at the bottom of the box barrel 1 into the soil of the paddy field or seedling field, ensure that the bottom opening of the box barrel 1 is blocked by soil or water, and some small holes of the hollow part 9 are above the soil or water surface. One of the insect attracting entrances 3 should face the wind direction as much as possible; Regularly change the placement position of the box barrel 1 in the field.
[0036] This method is the optimal way to use the insecticidal device. Even if this method is not followed, the insecticidal function can still be achieved. For example, if the insertion position of the box barrel 1 is deeper or shallower, there may be situations of insect attracting effect and escape of some pests, but it does not affect the overall feasibility.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
