Problems solved by technology
The first method: manual mechanical method, directly kills insects, but the labor cost is high and the efficiency is low
The second method: applying chemical fertilizers, but with the extensive use of chemical fertilizers, the resistance of pests is becoming stronger and stronger, and the ecological environment has also been polluted to a certain extent
The third method: the introduction of biological natural enemies, although it can limit specific pests very well, but the effect of biological control is slow, unable to deal with emergencies, and only relying on biological control cannot achieve good results
However, there is no report using the present invention

Embodiment Construction
[0015] In order to describe in detail the technical content, achieved purpose and effect of the technical solution, it will be described in detail below in conjunction with specific embodiments.
[0016] In this embodiment, a pulse signal of 1-4 Kv Kv is generated by a high-voltage pulse generating system. Its circuit includes an IGBT single-tube switch circuit, a high-frequency oscillation circuit and a voltage doubler rectification circuit. Connect the DC power supply to the IGBT collector terminal. When the IGBT is turned on under the control of the square wave signal, the DC power is converted into AC power through the high-frequency oscillation circuit, and finally the high-voltage pulse with an amplitude of 1 to 4Kv Kv is output through voltage doubler rectification. Wherein, the conduction of the switch tube is realized by adjusting the PWM controller. process result:

The invention provides a slug moth killing method based on a pulsed electric field. The method achieves the killing effect on slug moth pests in the electric field through forming a high-voltage pulsed electric field with the pulse amplitude from 1 Kv to 4 Kv and adjusting the frequency of the electric field to be 50-70 Hz and the pulse electrifying time to be 20-60 seconds, and the arranged powergrid includes, but is not limited to, an above-ground grid. According to the method, pests can be killed in a short time, and the arranged power grid does not damage plants and is beneficial to the growth of the plants; and the method has the advantages of no biochemical pollution, good insecticidal effect, safety and reliability.
Description
technical field [0001] The invention relates to the field of orchard planting, in particular to a method for killing moths based on pulsed electric fields. Background technique [0002] In Fenghua District, Ningbo City, Zhejiang Province, honey peach is an important source of agricultural economy, and it is very important to ensure the quality of the fruit. As a common pest in the growth process of juicy peaches, moths have brought considerable losses to fruit farmers every year. In order to ensure maximum economic benefits, it is necessary to effectively kill them. [0003] There are three common methods of hunting. The first method: manual mechanical method, directly kills insects, but the labor cost is high and the efficiency is low. The second method: applying chemical fertilizers, but with the extensive use of chemical fertilizers, the resistance of pests is becoming stronger and stronger, and the ecological environment has also been polluted to a certain extent.
