Embodiment 1

[0033] Equipment used such as figure 1 As shown: there is a transformer B, the positive terminal of the secondary of the transformer B is connected to the electrode 1 through the diode D, and the negative terminal of the transformer B is connected to the electrode 2. The main function of the diode D is rectification, and other rectification circuits can be selected. Such as bridge rectifier circuit and so on. The method of use is also shown in the figure: bury the electrodes 1 and 2 with the electrode handle in the soil with a moisture content of 5-40%. If the moisture content is 28-34%, the electrolysis effect is the best, and the electrodes 1 and 2 are parallel. And corresponding setting, the embedment depth of the electrodes 1 and 2 and the distance between the two electrodes shall be subject to the electrolysis effect, and the soil shall be electrified and electrolyzed. In order to obtain the best electrolysis effect, the embedment depth of the electrodes 1 and 2 in the s...

Embodiment 2

[0035] Equipment used such as figure 2 As shown: there is a transformer B, the positive terminal of the secondary of the transformer B is connected to the electrode 1 through the diode D, the negative terminal of the transformer B is connected to the electrode 2, and the power polarity changeover switch K1 is connected to the electrode 1 and the electrode 2 , K2, switch K1, K2 can choose to manually toggle the switch, or use a cycle timer. After each electrolysis for 3 to 10 minutes, change the electrode polarity so that the soil can be electrolyzed at the positive and negative electrodes in rotation.

[0036] It is also possible to set a pulse modulation integrated block in the circuit to generate a DC pulse current.

Embodiment 3

[0038] Others can be with embodiment 1 or embodiment 2, only electrode 1 or electrode 2 are at least two in parallel, and the connection method is as follows image 3 As shown, the specific number can be determined according to the rated power of the entire device. If the voltage is less than 90V and the current is less than 40A, the number of electrodes can be set to 2 to 3, and the longest electrode connection between the electrodes and the power supply should not exceed 70m.

Abstract

An electric treating method for getting over the continuous cropping obstructions of soil, such as infectious diseases and pests, the harmful substances including organic acid and high pH value, features that two electrodes connected to the positive and negative ends of power supply respectively are parallelly and oppositely buried in the soil whose water content is 5-40% and a voltages is applied across them for electrolyzing the soil. Its apparatus features that the positive end of the second winding of a transformer is connected via diode to one electrode and its negative end is directly connected to another electrode.

Description

Technical field: [0001] The invention relates to a soil treatment method and equipment, in particular to an electrical treatment method and equipment capable of eliminating soil continuous cropping obstacles. Background technique: [0002] In the past ten years, due to the increasing perfection of greenhouses and their supporting equipment, greenhouse plant products have entered a stable production stage, and producers have continued to produce high-value products (greenhouse vegetables, flowers, economic trees) due to market needs and land constraints. production, resulting in continuous cropping obstacles in the soil, affecting the growth and development of plants and reducing product returns. Continuous cropping obstacles are specifically reflected in the following aspects: [0003] 1. Soil-borne diseases are rampant, such as cucumber and watermelon wilt, eggplant verticillium wilt, brown spot disease, cotton blight, tomato early blight, late blight, bacterial wilt, bact...
