Electrical treatment method and appts for soil continuous prodn obstacle

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...

AI Technical Summary

Problems solved by technology

[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, bacterial wilt, viral diseases, pepper anthracnose, blight, Bean rust, downy mildew of spinach and onion, etc., can also cause rampant nematode diseases;

[0004] 2. The organic acids and harmful substances secreted by the root system are not easy to remove, resulting in poor root growth, such as more organic acids left by the rhizobia of legumes and vegetables;

[0007] Due to the pollution problem caused by the application of pesticides, for the above-mentioned continuous cropping obstacles, except that the lack of nutrient elements in the plow layer can be solved by fertilization, other obstacles have not yet had a good physical solution so far
