Description

Technical Field

[0001] This invention relates to a pesticide-free management method and system for aphids on the surface of corn leaves by low-pressure stimulation induction and high-pressure extermination, belonging to the field of field pest and disease management. Background Technology

[0002] There are three main methods for managing pests and diseases in the field: biological control, chemical control, and physical control. Biological control controls pest populations by introducing or protecting natural enemies and pathogenic microorganisms. However, it is slow to take effect, and its effectiveness is easily limited by environmental conditions. Introducing natural enemies and pathogenic microorganisms may disrupt the ecological balance, hindering its widespread adoption. Chemical control relies on the toxicity of chemical agents to control pests and diseases. This method is overly dependent on chemical agents, and long-term use can lead to pesticide resistance in pests, pollute the environment, and disrupt the ecological balance, also hindering its widespread adoption. Physical control directly blocks pests and diseases by altering environmental conditions or using mechanical means. It has advantages such as low cost and environmental friendliness. Currently, physical control mainly uses insecticidal lamps and color-block traps. Both are installed in fixed locations and only have a certain killing effect on localized pests and diseases, failing to achieve comprehensive field pest and disease management. Summary of the Invention

[0003] This invention relates to a pesticide-free management method and system for aphids on corn leaf surfaces using low-pressure stimulation induction and high-pressure extermination. The aim is to address the problems of traditional biological control methods, which are slow to take effect and whose control efficacy is easily limited by environmental conditions; chemical control methods, which easily lead to pesticide resistance in pests, pollute the environment, and disrupt the ecological balance; and physical control methods, such as insecticidal lamps and color-block traps, which are installed in fixed locations and only have a certain killing effect on local pests and diseases, failing to achieve overall field pest and disease management and hindering large-scale promotion and application.

[0004] This invention relates to a pesticide-free management method and system for aphids on corn leaf surfaces using low-pressure stimulation induction and high-pressure eradication. Its structure mainly consists of a low-pressure stimulation induction section, an airflow guidance section, and a high-pressure eradication section. The low-pressure stimulation induction section uses a pulse generator to generate an electric field that stimulates aphids, causing them to perceive a potential difference across their cell membranes, leading to sensory system disorder and prompting them to actively stop feeding and leave the corn leaf surface, thus preparing conditions for aphid migration. The airflow guidance section uses an air pump to generate air force to guide the aphids that have actively left the corn leaf surface to the eradication net, preparing for high-pressure eradication. The system is equipped with the following components: a high-voltage killing section uses a high-voltage electrostatic generator to produce high voltage to kill aphids, achieving pesticide-free control; a low-voltage stimulation induction section reduces energy consumption in the airflow guidance process, preventing damage to corn plant leaves; the low-voltage stimulation induction section and the airflow guidance section are located in the airflow guidance chamber, while the high-voltage killing section is located in the killing chamber, with the killing net arranged inside the killing chamber and connected to the high-voltage electrostatic generator; a shielding net is installed between the airflow guidance chamber and the killing chamber to prevent the high voltage in the killing chamber from forming an electric field that enters the airflow guidance chamber and affects the later growth and development of the corn plants.

[0005] Compared with existing technologies, this invention utilizes a low-pressure stimulation induction section to generate an electric field that induces aphids to actively stop feeding and leave the surface of corn leaves. The airflow guidance section generates pneumatic force to guide the aphids to the killing net. The high-voltage killing section generates high voltage to kill the aphids, achieving the purpose of pesticide-free killing. It has the characteristics of being fast-acting, green and pollution-free, and can be widely promoted. Moreover, the low-pressure stimulation induction section can reduce the energy consumption of the airflow guidance link and avoid damage to corn leaves. Attached Figure Description

Detailed Implementation

[0009] The following is in conjunction with the appendix Figure 1-2 The structural principles and implementation schemes of the present invention will be described in detail.

[0010] This invention relates to a drug-free management method and system for aphids on the surface of corn leaves by low-pressure stimulation induction and high-pressure killing, the structure of which mainly consists of low-pressure stimulation induction, airflow guidance and high-pressure killing parts.

[0011] The working process of this invention is as follows: During operation, the 2-pulse generator is turned on, and the 2-pulse generator generates an electric field to stimulate and induce the aphids to sense the potential difference between the inside and outside of their cell membranes, causing their sensory system to become disordered. This causes them to actively stop feeding and leave the surface of the corn leaf, preparing conditions for aphid migration. The airflow guidance section, using the 5-air pump to generate 3-air force, guides the aphids that have actively left the corn leaf surface to the 7-killing net, preparing conditions for high-voltage killing. The high-voltage killing section, using the 12-high-voltage electrostatic generator to generate high voltage, kills the aphids, achieving pesticide-free eradication. Purpose of the killing: The low-pressure stimulation induction part can reduce the energy consumption of the airflow guidance link and avoid damage to the leaves of the 6-corn plants; the low-pressure stimulation induction part and the airflow guidance part are in the 9-airflow guidance chamber, the high-pressure killing part is in the 10-killing chamber, the 7-killing net is arranged in the 10-killing chamber, and the 7-killing net is connected to the 12-high-voltage electrostatic generator; an 8-shielding net is installed between the 9-airflow guidance chamber and the 10-killing chamber to prevent the high voltage in the 10-killing chamber from forming an electric field that enters the 9-airflow guidance chamber and affects the later growth and development of the 6-corn plants.
