Description

Technical Field

[0001] The invention belongs to the technical field of pest control, and specifically is a green pest control method for rice planting. Background Art

[0002] The rice water weevil is a destructive pest on rice and one of the major quarantine pests in my country. It is listed as one of the world's 100 most threatening invasive alien species. In my country, the insect has become the second largest pest of rice after the rice planthopper. At present, the prevention and control of rice water weevils is still mainly chemical control. Furadan granules have always been the main agent for the prevention and control of rice water weevils. However, after the drug was banned in 1995, fipronil, thiamethoxam, and chlorfenapyr became the main alternative agents for the prevention and control of rice water weevils. Although the widespread use of the above-mentioned agents has a good control effect on the occurrence and damage of the pest, it also has a certain toxic effect on non-target organisms, especially invertebrates, and the environmental pollution problems caused are becoming more and more prominent. In this context, actively carrying out the screening of low-toxic, low-residue, and pollution-free biological agents that meet green production standards has become the primary task facing the prevention and control of rice water weevils.

[0003] In the existing technology, green pest control is carried out through drugs, breeding and biological natural enemies, but pests and diseases can be transmitted to each other in the field. It is very likely that after pests are eliminated in the current area, the pests will spread back from other areas and occur again. Summary of the invention

[0004] In order to solve the above problems, the purpose of the present invention is to provide a green control method for rice planting diseases and insect pests, which can reduce the spread of pests in different areas.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows: a green control method for rice planting pests and diseases, comprising the following steps:

[0006] Step 1: Plant rice in different areas. Each area of ​​rice shares the same irrigation canal system. Each area of ​​rice is provided with a water outlet and a water inlet, and valves are provided at the water outlet and the water inlet.

[0007] Step 2: An insect trap is set at both the water outlet and the water inlet. The insect trap is located in the water. A blocking net is set on both sides of the insect trap. The insect trap is used to trap insects that enter the insect trap from the water.

[0008] Step 3, regularly using an ejector to treat the rice, the ejector is used to eject water in the rice single zone onto the rice plants, and the insects on the rice plants are impacted into the water, the water outlet is closed before ejection to raise the water level in the rice single zone, and the water outlet is opened after ejection to make the water in the rice single zone flow toward the outlet and carry the fallen or aquatic insects, and the insect trap collects the insects;

[0009] Step 4: Regularly remove the insects from the insect trap for cleaning.

[0010] The following beneficial effects are achieved by adopting the above scheme:

[0011] 1. Rice pests can spread through irrigation water, so insect traps are set at the outlet and inlet to reduce the probability of pests spreading through the irrigation water system. During the irrigation process, water flows to the outlet, so that insects spread by irrigation water will pass through the insect traps, which improves the efficiency of insect capture and reduces the probability of pests spreading between rice areas.

[0012] 2. The net will intercept the insects in the water and allow the water to flow through, so that the insects can only enter the insect trap with the water flow and have difficulty entering other rice areas.

[0013] 3. The ejector can spray water to knock down insects attached to rice. The ejector directly uses irrigation water in the rice area for spraying, using local materials. The ejector can mix pesticides for use, and spray pesticide solutions for pest prevention when repelling insects.

[0014] 4. Before spraying, close the water outlet to raise the water level in the rice area and store water in the rice area. After the sprayer treatment is completed, open the water outlet. At this time, the water level in the rice area is higher, which will cause the water to flow to the water outlet and capture the insects shot down in the water and some aquatic insects.

[0015] Compared with the existing technology, placing insect traps at the water outlet not only reduces the spread of pests between different areas, but also can kill insects through green and harmless means. The water flow will converge at the water outlet, so that the insects will gather at the interception net and the insect trap, improving the efficiency of insect capture. Using an ejector to treat rice can knock down insects, and cooperate with the water outlet and water inlet to control the water level in the rice single area, so that the knocked down insects enter the insect trap with the water flow.

[0016] Furthermore, the insect trap is powered by clean energy.

[0017] Beneficial effects: The insect trap is in the wild and can be driven by light energy, wind energy, water energy, etc., making its energy source cleaner and low-carbon.

[0018] Furthermore, the insect catcher includes a base plate, a rotating shaft is provided in the middle of the base plate, a plurality of fixed arc teeth are fixedly connected circumferentially on the base plate, a rotating arc tooth is fixedly connected to the rotating shaft, the fixed arc teeth and the rotating arc teeth are both composed of a plurality of fins, the fins of the fixed arc teeth and the rotating arc teeth are staggered, the rotating arc teeth are provided with a connecting rod, the fins of the rotating arc teeth are all fixedly connected to the connecting rod, one end of the connecting rod is fixedly connected to the rotating shaft, a capturing cavity is opened on the rotating shaft, and the capturing cavity is used to collect insects in the closed cavity after the fixed arc teeth and the rotating arc teeth cooperate.

[0019] Beneficial effect: The rotating shaft drives the rotating arc teeth to rotate, and the rotating arc teeth are stuck in the fixed arc teeth. As the rotating shaft rotates, the area enclosed by the rotating arc teeth and the fixed arc teeth becomes smaller and smaller, until the rotating arc teeth pass through the fixed arc teeth and match with the next fixed arc teeth. Insects will be trapped in the area enclosed by the rotating arc teeth and the fixed arc teeth. As the area becomes smaller and smaller, they will enter the capture chamber and be collected.

[0020] Furthermore, the rotating shaft extends to the outside of the bottom of the base plate and is coaxially fixedly connected with a hydraulic wheel.

[0021] Beneficial effect: The hydraulic wheel can convert the flow of water into the rotation of the rotating shaft, thereby driving the insect trap.

[0022] Furthermore, in step 2, the blocking net and the insect catcher form a trumpet-shaped gathering structure.

[0023] Beneficial effect: The trumpet-shaped gathering structure can guide the insects caught by the blocking net to the insect trap so that they can be caught.

[0024] Furthermore, the ejector comprises a casing, a power source is fixedly connected to the casing, and a first pump body is fixedly connected to the casing.

[0025] Beneficial effect: The first pump body can absorb water in a single rice area and form an impact water column to knock insects into the water.

[0026] Furthermore, a mixing box is fixedly connected to the casing, a pharmaceutical solution mixer is arranged in the mixing box, a second pump body is arranged in the mixing box, and the second pump body is connected to a nozzle.

[0027] Beneficial effects: The mixing box can be used for mixing the pesticide solution, so that the water column sprayed from the nozzle is mixed with the pesticide components, so that the pesticide can be used to prevent diseases and insect pests during the process of spraying pests.

[0028] Furthermore, a controller is provided in the casing, and a rice stem diameter measuring device is fixedly connected to the casing. The controller is used to control the spraying amount of the second pump body according to the diameter detected by the rice stem diameter measuring device.

[0029] Beneficial effects: The rice stem diameter measuring device can measure the diameter of the rice stem, thereby judging the current rice growth stage based on the diameter of the rice stem and controlling the impact force of the spray.

[0030] Further, the nozzle discharges water upward.

[0031] Beneficial effect: The upward water discharge from the nozzle can generate an impact force from bottom to top, thereby knocking down insects.

[0032] Furthermore, in step 4, when the insects in the insect trap are taken out, the number of captured insects is recorded, and based on the recorded number of insects, the frequency of treating rice with the sprayer in the corresponding rice zone is adjusted.

[0033] Beneficial effect: Recording the number of captured insects can reflect the intensity of pests in the current rice area, thereby adjusting the frequency of rice treatment according to the intensity of pests. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment 1

[0040] The embodiment is basically as shown in the attached Figure 1 To Attachment Figure 3 As shown:

[0041] A green rice planting pest control method comprises the following steps:

[0042] Step 1: Plant rice in different areas. Each rice area shares the same irrigation canal system. Each rice area is provided with a water outlet and a water inlet, and valves are provided at the water outlet and the water inlet.

[0043] Sharing the same irrigation canal system allows water to flow between rice areas, and the amount of water in a single rice area can be controlled through valves at the outlet and inlet, thereby controlling the water level.

[0044] Step 2, an insect trap is set at the water outlet and the water inlet, the insect trap is located in the water, the insect trap includes a base plate 1, a rotating shaft 4 is provided in the middle of the base plate 1, a plurality of fixed arc teeth 2 are distributed circumferentially on the base plate 1, the fixed arc teeth 2 are integrally formed with the base plate 1, and a rotating arc tooth 3 is integrally formed on the rotating shaft 4, the fixed arc teeth 2 and the rotating arc teeth 3 are both composed of a plurality of fins, the fins of the fixed arc teeth 2 and the rotating arc teeth 3 are staggered, the rotating arc teeth 3 are provided with a connecting rod, the fins of the rotating arc teeth 3 are fixedly connected to the connecting rod, one end of the connecting rod is fixedly connected to the rotating shaft 4, a capturing chamber 5 is opened on the rotating shaft 4, the capturing chamber 5 is used to collect insects in the closed chamber after the fixed arc teeth 2 and the rotating arc teeth 3 cooperate, the rotating shaft 4 extends to the outside of the bottom of the base plate 1 and is fixed with a hydraulic impeller 6 with coaxial bolts, and blocking nets 7 are pulled on both sides of the insect trap, the blocking net 7 and the insect trap form a trumpet-shaped retracting structure, and the insect trap is used to trap insects entering the insect trap in the water.

[0045] When the water flows, it drives the hydraulic wheel 6 to rotate, thereby driving the rotating shaft 4 to operate. The rotating shaft 4 drives the rotating arc teeth 3 to rotate, and the rotating arc teeth 3 are stuck in the fixed arc teeth 2. As the rotating shaft 4 rotates, the area enclosed by the rotating arc teeth 3 and the fixed arc teeth 2 will become smaller and smaller, until the rotating arc teeth 3 pass through the fixed arc teeth 2 and cooperate with the next fixed arc teeth 2. Insects will be trapped in the area enclosed by the rotating arc teeth 3 and the fixed arc teeth 2, and as the area becomes smaller and smaller, they will enter the capture chamber 5 and be collected.

[0046] For example, the rice water weevil is semi-aquatic and can spread through air and water flow. When the rice water weevil moves with the water flow, it will flow into the intercepting net 7 and the insect trap to form a trumpet-shaped gathering structure, and be guided into the insect trap, thereby being trapped and killed in the insect trap.

[0047] Step three, regularly using an ejector to treat the rice, the ejector is used to eject water in a single rice zone onto the rice plants, and impact insects on the rice plants into the water.

[0048] The sprayer can spray water to knock down insects attached to rice. The sprayer directly uses irrigation water in the rice area for spraying, using local materials. The sprayer can mix pesticides for use, and spray the pesticide solution to prevent pests and diseases when repelling insects.

[0049] The ejector includes a casing 8, a power source is bolted to the casing 8, a first pump body 9 is bolted to the casing 8, a mixing box 10 is bolted to the casing 8, the first pump body 9 is connected to the mixing box 10, a pharmaceutical solution mixer is arranged in the mixing box 10, the pharmaceutical solution mixer includes a syringe 11 and a stirring paddle 14, the syringe 11 is equipped with an electric push cylinder 12 for driving the discharge, the model of the electric push cylinder 12 is HB-DJ806, the syringe 11 is bolted to the side wall of the mixing box 10, and the stirring paddle 14 is equipped with a motor for driving the rotation thereof 13, a stirring paddle 14 is rotatably connected to the bottom wall of the mixing box 10, a second pump body 15 is bolted in the mixing box 10, the second pump body 15 is connected to a nozzle 16, the nozzle 16 discharges water upward, a controller 17 is screwed in the casing 8, a rice stem diameter measuring device 18 is bolted on the casing 8, the rice stem diameter measuring device 18 is an electronic vernier caliper, the model of the rice stem diameter measuring device 18 is DL91150, and the controller 17 is used to control the spraying amount of the second pump body 15 according to the diameter detected by the rice stem diameter measuring device 18.

[0050] When in use, the syringe 11 is filled with a drug, which can be a Beauveria bassiana preparation. The injector is immersed in water, and the first pump body 9 can pump water from a single rice zone into the mixing box 10. The syringe 11 injects the Beauveria bassiana preparation into the mixing box 10, and then mixes it through the stirring paddle 14. The rice stem diameter measuring device 18 is used to measure the diameter of the rice, and the controller 17 controls the spraying amount of the second pump body 15 based on the diameter of the rice, reducing the water flow that will crush the rice plants when they are too small.

[0051] Before spraying, the water outlet is closed to raise the water level in the rice single area. After spraying, the water outlet is opened to make the water in the rice single area flow toward the water outlet and carry the fallen or aquatic insects, and the insect trap collects the insects.

[0052] Close the water outlet before spraying to increase the amount of water in the rice area. After the user flushes the insects, the insects will fall into the water body. Open the water outlet, and the water in the rice area will flow out to the outlet. The insect trap will capture the insects that fall into the water and some aquatic insects.

[0053] Step 4: Regularly take out the insects in the insect trap for cleaning. When the insects in the insect trap are taken out, record the number of captured insects. Based on the recorded number of insects, adjust the frequency of treating rice with the sprayer in the corresponding rice zone.

[0054] Recording the number of captured insects can reflect the intensity of insect pests in the current rice area, thereby adjusting the frequency of rice treatment according to the intensity of the pests.
