Problems solved by technology

[0002] For a long time, the prevention and control of soil-borne diseases of crops in open fields, such as fusarium wilt, verticillium wilt, and blight of various crops, have mostly used medicaments mixed with fine soil to sprinkle or use thicker liquids to irrigate the soil, and the control effect is poor. , the cost is high, the duration is short, and many diseases cannot be controlled, and the more the disease is prevented, the more serious it is, causing farmers to strengthen the excessive use of pesticides to form a vicious circle, which not only pollutes the soil, but also increases the cost of prevention and control
Methyl bromide fumigation soil disinfection technology has been completely restricted due to its damage to the atmospheric environment
Using lime and straw to treat soil at high temperature in the sun or purely using solar energy for harmless disinfection, the effect is ideal, but both need to last for a long time, and the film used after high temperature treatment is easy to age, resulting in increased control costs

Abstract

A method for killing the harmful living things in soil by use of ozone includes such steps as deep ploughing for breaking off the soil while spraying water until the content of water in soil is 55-75%, making ridges, covering a plastic film on the ridges, sealing the edges of said plastic film, filling ozone into the space under plastic film at the speed of 10g / hr for 90-150 hr, and removing the plastic film.

Description

technical field [0001] The invention relates to a method for killing various germs, pests and other harmful organisms in open farmland soil. Background technique [0002] For a long time, the prevention and control of soil-borne diseases of crops in open fields, such as fusarium wilt, verticillium wilt, and blight of various crops, have mostly used medicaments mixed with fine soil to sprinkle or use thicker liquids to irrigate the soil, and the control effect is poor. , the cost is high, the duration is short, and many diseases cannot be controlled. The more the disease is prevented, the more serious the disease is, causing farmers to intensify the excessive use of pesticides to form a vicious circle, which not only pollutes the soil, but also increases the cost of prevention and control. The use of methyl bromide fumigation soil disinfection technology has been completely restricted due to its damage to the atmospheric environment. Using lime and straw to treat the soil at...
