Problems solved by technology

Usually, the measure to prevent and control the pathogen is to kill it with pesticides such as ketone, but the large-scale use of pesticides not only causes great harm to the environment and soil, but also poses a great threat to food safety.

Embodiment Construction

[0031] Ozone water preparation

[0032] Such as figure 1 , figure 2 As shown, for the ozone water preparation system provided by the present invention, the ozone coming out from the ozone generator 7 enters the lower part of the gas-liquid mixing tower 10, first passes through the support 9 provided with the mesh metal plate, and then is fixed on the support 9 through the same process. The titanium gold aerator 3 on the top of the gas-liquid mixing tower 10 is equipped with 4 titanium gold aerators 3, so that the ozone can be more uniformly dispersed in the gas-liquid mixing tower 10, and the fully dispersed ozone can flow from the gas-liquid mixing tower. 10 The lower part moves upwards.

[0033] Sterile water is pumped into the top of the gas-liquid mixing tower 10 by the pump 1, and an electronic control valve 2 is provided after the pump 1, and the control box 6 controls the opening or closing of the electronic control valve 2. The sterile water is firstly distribute...

Abstract

The invention provides a vegetable disease control method. The method puts ozone water on surfaces of vegetables to kill pathogenic bacteria on the surfaces of the vegetables or prevent the vegetables from diseases; the ozone water is prepared by an ozone generator, ozone gas is prepared firstly, and then the ozone gas and water is mixed in a gas-liquid mixing tower to obtain the ozone water. The method adopts the ozone water to control the pathogenic bacteria on the vegetables and is environment-friendly. Redundant ozone water rapidly decomposes into oxygen gas and will not cause secondary pollution to an environment or soil, and pesticide residue on the vegetables can be avoided; and in addition, microorganism bacteria can directly react with ozone dissolved in water and can indirectly react with hydroxyl radical generated by decomposition of the ozone, the hydroxyl radical is an oxidizing agent having high oxidizing ability, and then the ozone water can rapidly kill the pathogenic bacteria.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a method for preventing and treating vegetable diseases. Background technique [0002] Facility agriculture is relative to traditional agriculture. It uses artificially built facilities to make traditional agriculture gradually get rid of the shackles of nature and move towards modern factory agricultural production. It is an effective way to further meet the needs of diversified and multi-level consumption. [0003] Facility cultivation is 3.5 times the output of open-air cultivation. In 2012, the area of ​​facility agriculture in my country has accounted for more than 85% of the world's total area, and the per capita arable land area in my country is only 40% of the world's per capita area. One of the effective technical projects that restricts sustainable development issues. [0004] Covering cultivation with insect-proof nets is a practical and environmentally friendly agricultura...
