specific Embodiment approach 1

[0012] Specific implementation mode one: (see figure 1 ) The present embodiment comprises the ozone generator 1, the first pipeline 3, the gas-liquid mixing device 4, the water inlet pipe joint 6, the second pipeline 10 and the irrigation device 11, and one end of the first pipeline 3 communicates with the outlet of the ozone generator 1 , the other end of the first pipeline 3 communicates with the input end of the gas-liquid mixing device 4, the gas-liquid mixing device 4 is fixedly connected with a water inlet pipe joint 6, and one end of the second pipeline 10 is connected with the output end of the gas-liquid mixing device 4 The other end of the second pipeline 10 communicates with the irrigation device 11.

specific Embodiment approach 2

[0013] Specific implementation mode two: (see figure 1 ) In this embodiment, the third pipeline 2, the first valve 5, the second valve 7, the third valve 8 and the fourth pipeline 9 are added, and the third valve 8 is connected in series between the gas-liquid mixing device 4 and the irrigation device 11 On the second pipeline 10, one end of the first valve 5 communicates with the water inlet pipe joint 6, the other end of the first valve 5 communicates with the side wall of the third pipeline 2, and one end of the second valve 7 communicates with the third pipeline 2 The other end of the second valve 7 communicates with one end of the fourth pipeline 9 , and the other end of the fourth pipeline 9 communicates with the second pipeline 10 . This embodiment is used for disinfection of soil, and can also be used for irrigation of orchards, trees and fields. When being used for the disinfection of soil, the first valve 5 and the third valve 8 are opened, and the second valve 7 is...

specific Embodiment approach 3

[0014] Specific implementation mode three: (see figure 2 ) This embodiment is used for the disinfection of soil in plastic greenhouses or greenhouses. Irrigation device 11 is arranged in plastic greenhouses or greenhouses 12. Ultraviolet lamps 13 and ozone concentration sensors 14 are also provided in plastic greenhouses or greenhouses 12. The bottom of 12 is also provided with the exhaust ventilation fan 15 that communicates with plastic greenhouse or greenhouse 12 inside and outside. When the ozone concentration sensor 14 of this embodiment detects that the ozone concentration exceeds the standard, the automatic control system reminds people not to enter the greenhouse. If you want to enter the greenhouse, you need to automatically or manually turn on the ultraviolet light 13 to decompose the ozone gas, and you can also turn on the exhaust fan 15 to reduce the ozone concentration. People can enter the greenhouse when the ozone concentration is reduced below the warning line...

Abstract

The invention provides to a device for disinfecting the soil through ozone and a method thereof. The invention relates to a device for preventing soil-borne diseases and plant diseases and insect pests and a method for disinfecting the soil. The invention aims to solve the problems that the prior method for disinfecting the soil through chemical reagents such as bromethane pollutes the environment and jeopardizes the human health; and the prior physical disinfection method has low efficiency or high cost. The invention provides the ozone soil disinfection device with greenness, environmental protection, no pollution and residue, and low cost, and the soil disinfection method. One end of a first pipe is communicated with an ozone generating device; and the other end of the first pipe is communicated with the input end of a gas-liquid mixing device. A water inlet pipe connector is arranged on the gas-liquid mixing device. One end of a second pipe is communicated with the output end of the gas-liquid mixing device; and the other end of the second pipe is communicated with an irrigation rig. The application method is that: the soil disinfection is carried out before crop planting; the ozone concentration in the ozone water is 1 to 10mg / L; and the amount of the ozone water for flooding irrigation is 45 to 55 tons / mu.

Description

technical field [0001] The invention relates to a device for disinfecting soil with ozone and a method for disinfecting soil. Background technique [0002] Crop diseases and insect pests are one of the main natural disasters faced by human beings. It has the characteristics of various types, great impact and frequent outbreaks. The loss of fruit trees and vegetables due to pests and diseases is about 15-20% in the world every year. Since the 1950s in my country, the occurrence area of ​​major crop diseases and insect pests has been increasing, especially since the early 1970s, the occurrence area and frequency of diseases and insect pests have increased year by year, which has become the main restrictive factor for the development of high-yield, high-quality, and efficient agriculture in my country. [0003] At present, chemical pesticides are mainly used to control pest disasters. Due to the long-term and large-scale use of pesticides, the air, water, soil and food are po...
