Description

Technical Field

[0001] The invention relates to the technical field of vegetable cultivation, and in particular to a method for preventing and controlling soil-borne diseases of tomatoes. Background Art

[0002] Vegetable cultivation covers all aspects related to vegetable planting and growth management. Soil-borne diseases refer to pathogens such as fungi, bacteria, nematodes and viruses that live in the soil with diseased remains and attack crops from the roots or stems when conditions are right. Prevention and control of soil-borne diseases of tomatoes is crucial for tomato cultivation. Once these diseases occur, they will cause poor growth, reduced yields or even death of tomato plants, causing huge economic losses to growers.

[0003] In the prior art, soil disinfection is usually used to prevent and control soil-borne diseases during tomato cultivation. That is, before planting tomatoes, soil treatment is performed using disinfectants to inhibit the growth and reproduction of pathogens, reduce the number of pathogens, and reduce the probability of disease occurrence. When using a backpack sprayer to spray disinfectants, workers need to hold a spray tube and spray the soil. The spray tube generally maintains a large distance from the soil. In windy weather, the sprayed agent particles are easily blown away by the wind, especially small particles, which can easily cause the agent to be blown out of the spraying area. In order to reduce the agent being blown away by the wind, the worker needs to bend down and lower the height of the arm, thereby reducing the distance between the spray tube and the soil and reducing the probability of the agent being blown away by the wind. This will increase the physical exertion of the workers. Working in such a posture for a long time can easily cause physical discomfort, and even cause damage to the waist and shoulders, which is not conducive to the health of the workers.

[0023] The working principle of this embodiment is as follows: when in use, the battery 104, the PLC controller 110, the liquid pump 202, the laser ranging sensor 209, the solenoid valve 211, the forward and reverse motor 216, the electric push rod 301 and the control console 105 are electrically connected, the battery 104 is used to power other devices, the control console 105 sends an operation instruction to the PLC controller 110, and the PLC controller 110 starts the corresponding device to turn on or off according to the received operation instruction. The bottom of the mobile vehicle 101 is provided with a universal wheel with a built-in brake to facilitate the movement of the mobile vehicle 101. The sealing cover 107 is unscrewed, and the prepared disinfectant is poured into the medicine box 102 through the liquid inlet pipe 106, and the mobile vehicle 101 is pushed to drive the adjustment component 2 and the windproof component 3 move together, through the moving component 1, it is convenient to push the medicine spraying equipment to move, and the staff does not need to carry the spraying equipment, which reduces the burden and pressure on the staff. The two solenoid valves 211 are in the open state, and the valve 109 is in the closed state. The liquid pump 202 is started, and the disinfectant in the medicine box 102 is pumped into the telescopic tube 204 and the fixed tube 206 through the liquid extraction pipe 214, and then enters the diversion pipe 210 for diversion, and then enters the two medicine pipes 212, and the disinfectant is sprayed into the soil below through the two spray heads 213 to treat the soil. When encountering windy weather, it is necessary to lower the height of the spray head 213 to reduce the distance between the spray head 213 and the soil, and the forward and reverse motors 216 are started. The rotation of the output end 216 drives the rotating shaft 217 and the gear 218 to rotate, and the gear 218 is meshed with the row of gear plates 207.

[0026] Embodiment 3: According to Figure 1-Figure 8 As shown, a method for preventing and controlling soil-borne diseases of tomatoes comprises the following steps: In the first step, a universal wheel with a built-in brake is provided at the bottom of the mobile vehicle 101, and the mobile component 1 is used to facilitate the movement of the medicine spraying equipment; The second step is to start the liquid pump 202, pump the disinfectant into the telescopic tube 204 and the fixed tube 206 through the liquid pumping tube 214, enter the two drug tubes 212 through the diverter tube 210, and spray the disinfectant into the soil below through the spray head 213; The third step is to start the forward and reverse motor 216, drive the rotating shaft 217 and the gear 218 to rotate, and drive the tooth plate 207 to move downward, so that the diverter pipe 210 and the fixed pipe 206 move downward, and drive the windproof component 3, the two medicine pipes 212 and the two spray heads 213 to move downward together, so as to lower the height of the spray heads 213; The fourth step is to start the electric push rod 301, pull the moving plate 302 and the reinforcing rod 303 downward, and drive the windproof sleeve 304 to move downward, so that most of the space between the spray head 213 and the soil is covered in the windproof sleeve 304, maintaining effective protection for the agent.

[0027] The working principle of this embodiment is as follows: when in use, the movement of the spraying equipment can be achieved through the mobile vehicle 101 in the mobile component 1, and the staff does not need to carry the spraying equipment. The battery 104 is used to power other equipment, and the control console 105 sends an operation instruction to the PLC controller 110. The PLC controller 110 starts the corresponding equipment to turn on or off according to the received operation instruction, starts the liquid pump 202, and transports the disinfectant through the liquid suction pipe 214, the infusion pipe 203, the telescopic pipe 204, the shunt pipe 210 and the agent pipe 212. Finally, the spray head 213 sprays the disinfectant onto the soil. After the application of the medicine, the soil is turned over to promote the full mixing of the medicine and the soil, enhance the disinfection effect, and spray the disinfectant so that the medicine directly acts on the pathogens in the soil, inhibits the growth and reproduction of the pathogens, reduces the number of pathogens, and thus reduces the probability of the disease, so that it cannot cause harm to the tomato plants.

[0028] The effect and working principle achieved by the entire mechanism are as follows: by moving the component 1, it is convenient to push the pesticide spraying equipment to move, and the staff does not need to carry the spraying equipment, which reduces the burden and pressure on the staff. The liquid pump 202 is started, and the disinfectant in the pesticide box 102 is pumped into the telescopic tube 204 and the fixed tube 206 through the liquid extraction pipe 214, and then enters the diversion pipe 210 for diversion, and then enters the two pesticide pipes 212, and the disinfectant is sprayed into the soil below through the two spray heads 213 to treat the soil. The agent directly acts on the pathogens in the soil, inhibits the growth and reproduction of the pathogens, reduces the number of pathogens, and thus reduces the probability of disease occurrence, so that it cannot cause harm to the tomato plants.When encountering windy weather, the forward and reverse motor 216 is started to drive the rotating shaft 217 and the gear 218 to rotate, and the gear 218 is meshed with the row of gear plates 207. The rotation of the gear 218 drives the row of gear plates 207 to move downward, and drives the reinforcing plate 208 to move downward on the outer surface of the limit rod 4, and at the same time drives the mounting block 220 and the two supporting blocks 221 to move downward together, and further drives the shunt pipe 210 and the fixed pipe 206 to move downward, so that the telescopic pipe 204 shrinks together, and drives the windproof component 3, the two medicine pipes 212 and the two spray heads 213 to move downward together. When the forward and reverse motor 216 is automatically turned off, the two spray heads 213 move to a position close to the moving The height of the spray head 213 is lowered by pushing the mobile vehicle 101. The staff can keep the spray head 213 at a relatively low height to spray the disinfectant on the soil, thereby achieving the effect of adjusting the height of the spray head 213. The staff does not need to bend over and hold the device to operate, which reduces physical exertion and the damage to the body caused by carrying heavy objects. It is more convenient. When processing soil areas at different heights, the laser ranging sensor 209 is started to detect the distance between the reinforcing plate 208 and the soil, and the detected distance data is transmitted to the PLC controller 110 for identification in the form of an electrical signal. Then the PLC controller 110 transmits the distance data to the controller The staff can check the distance according to the display on the control console 105. The staff can start the forward and reverse motor 216 according to actual needs and turn off the forward and reverse motor 216 immediately according to the moving position of the spray head 213, thereby adjusting the height of the spray head 213 so that the spray head 213 maintains a suitable distance from the soil, which is convenient for the disinfectant to be sprayed onto the soil better.
