[0035] The soil mixing tank 1 includes a container body 11 and a power source 12 for driving the container body to rotate axially. The container body 11 has a second inlet 14 and a second outlet 15 controlled by a second solenoid valve 13. The container body 11 rotates and tumbles along the axial direction to mix the soil. The soil mixing tank 1 is further externally connected to a cold air blower 16, which is controlled to deliver cold air into the soil mixing tank 1.
[0036] The fallow tank 4 includes a vertically placed tank body 41. The upper part of the tank body 41 is provided with a first inlet 42, and the lower part of the tank body 41 is funnel-shaped 44. A first outlet 43 is provided at the confluence of the funnel-shaped 44. The inner cavity of the tank body 41 is provided with at least one humidity sensor 45, at least one humidifying nozzle 46, and an air supply device 40 for aeration of the soil loaded into the inner cavity of the tank body 41 and preventing compaction. The air supply device 40 includes several air nozzles 403, which are located at the lower part of the tank body 41. The outside of the tank body 41 is provided with a humidifier 47, a first solenoid valve 48, and a first pipeline 49. The first solenoid valve 48 serves as the air passage control valve for the first pipeline 49. The humidifier 47 delivers the generated moisture to the humidifying nozzles 46 through the first pipeline 49. The tank body 41 also includes a control device 6 for controlling the start / stop of the air supply device 40, the humidifier 47, and the first solenoid valve 48. In this embodiment, each cross-section of the tank 41 is circular, and the number of humidity sensors 45 is greater than or equal to 2, which are respectively arranged in the middle and bottom of the tank 41.
[0037] The air replenishment device 40 includes an air compressor unit 401 and an air explosion machine 402 outside the tank 41, a second pipeline 404, and a number of air nozzles 403 placed inside the tank 41.

The start / stop of the air compressor unit 401 is controlled by the control device 6.
[0038] In the existing field of plant and crop cultivation, planting boxes 5 are generally used to achieve industrialized and standardized planting. After one or two batches of planting are completed, the soil in the planting boxes 5 needs to be remediated. The following rapid soil remediation method can be adopted, which includes two steps: soil disinfection and nutrient addition, as follows:
[0039] Soil disinfection: After harvesting vegetables from planting box 5, the soil is poured into soil counting machine 7 for collection. The collected soil requiring remediation is fed into soil mixing tank 1 via first feeder 18. Simultaneously, fertilizer from fertilizer storage tank 2 is fed into soil mixing tank 1 via second feeder 21 according to a certain ratio, mixing the soil and fertilizer in proportion. Steam generator 17 generates steam and delivers it to the inner chamber of soil mixing tank 1 through external pipeline to disinfect the soil in soil mixing tank 1 at high temperature. The high temperature kills insect eggs, soil-borne viruses, and harmful microorganisms in the soil. In this embodiment, a cool air blower 16 then cools the soil in soil mixing tank 1. Cold air is delivered to achieve rapid cooling after the soil has been disinfected at high temperatures. The steam generator 17 delivers steam to the soil mixing tank 1 to ensure that the temperature inside is not lower than 65 degrees Celsius. Due to the large number of beneficial bacteria in the soil and the complete nutrient fertilizer formula, the beneficial bacteria have a high temperature tolerance of more than 80 degrees Celsius, and can survive at the extreme temperature of 87 degrees Celsius. However, the temperature tolerance of common viruses, harmful microorganisms, insect eggs and other harmful substances that seriously affect planting does not exceed 80 degrees Celsius. Generally, 65-75 degrees Celsius for 20 minutes is sufficient to kill them. This disinfection scheme is based on this characteristic and its effectiveness can exceed 90%.
[0040] Nutrient addition: The sterilized soil is fed into the tank 41 of the fallow tank 4 via the third feeder 31. Earthworms and earthworm feeder 3 are added to the sterilized soil in a controlled manner via the third feeder 31, and both enter the tank 41 of the fallow tank 4. The ambient humidity inside the tank 41 is detected by a preset humidity sensor 45. When the ambient humidity is lower than the preset condition, the humidifier 47 is controlled to generate moisture and spray it into the soil inside the tank 41 through the first pipe 49 and the humidification nozzle 46. The air supply device 40 is controlled to spray air into the soil inside the tank 41 through the air nozzle 403 to achieve soil aeration inside the tank 41 and to prevent soil compaction through vibration.
[0041] In this embodiment, a discharge machine 431 is further provided outside the first discharge port 43 at the bottom of the fallow tank 4 to discharge material according to a preset quantitative amount, such as... Figure 2 As shown, a seedling harvesting production line is a mobile production line. In this embodiment, the planting boxes that need soil repair are placed on the production line at the front. The soil is poured out by a soil dumping counter and fed to the soil mixing tank 1 by a first feeding machine. After completing all repair steps through the above repair process, the soil is discharged from the first outlet 43 of the fallow tank 4 and returned to the seedling harvesting production line via the discharge machine 431. Figure 2 As shown, the soil is added sequentially to the empty planting boxes via a soil metering machine to achieve quantitative feeding. Subsequent processes such as sowing and seedling cultivation can be completed on this production line, which will not be elaborated on again.
