[0028] As a further scheme of the present application, the inside of the microbial fertilizer storage box 4 is provided with a stirrer 14 and is fixed on the spreader frame 1, the upper side and the lower side of the outside of the microbial fertilizer storage box 4 are respectively provided with a medicine adding valve pipe 15 and a medicine discharging valve pipe 16, the top end of the medicine adding valve pipe 15 penetrates the spreader frame 1, the side of the spreader frame 1 away from the fixed frame 2 is fixed with a storage box 17, the four corners of the bottom of the spreader frame 1 are respectively provided with traveling wheels 18, and the top of the two sides of the spreader frame 1 is respectively fixed with a push handle 19. When working, the spreader frame 1 is pushed through the push handle 19, the spreader frame 1 drives the traveling wheels 18 at the bottom to roll, the spreading device is transferred to the fertilization area, the spreading device is moved away between the plants, the plants on the two sides of the device are spread, and the stirrer 14 is started to mix the liquid medicine in the microbial fertilizer storage box 4, so that the precipitation of the microbial fertilizer is prevented and the drug effect is affected.

[0029] The working principle of the present application is as follows: In the process of planting medicinal herbs under the Pinus massoniana forest, microbial fertilizer needs to be scattered after the medicinal herb plants are buried. The microbial fertilizer is added to the microbial fertilizer storage tank 4 through the dosing valve pipe 15 and is used after being mixed with water. The handle 19 is pushed to drive the spreading frame 1, which drives the bottom walking wheels 18 to roll, so that the spreading device is transferred to the fertilization area. Then the main valve 133 is opened, and the dosing pump 131 is controlled to work, so that the microbial fertilizer dosing pipe 132 extracts the liquid medicine in the microbial fertilizer storage tank 4. The liquid medicine enters the liquid guide pipe 135 through the connecting pipe 134, and the liquid guide pipe 135 guides the liquid medicine into the microbial fertilizer spray head 127 through the multiple branch pipes 1294 and the medicine guide flexible pipe 1293. The microbial fertilizer spray head 127 sends the liquid medicine into the nozzle 128 and sprays it out. At the same time, the handle 19 is pushed to move the spreading device between the plants, and the plants on both sides of the device are scattered. At the same time, the mixer 14 is started to mix the liquid medicine in the microbial fertilizer storage tank 4 to prevent the microbial fertilizer from precipitating and affecting the efficacy. During the spreading process, the second motor 101 is started, which drives the multiple worms 103 to rotate through the connecting shaft 102. The worms 103 drive the rotating shaft 122 to rotate through the worm gears 104. The bottom end of the rotating shaft 122 drives the deflection block 125 to rotate. Since the inclined surface at the bottom of the deflection block 125 is in parallel with the top of the microbial fertilizer spray head 127, the deflection block 125 drives the microbial fertilizer spray head 127 to deflect inside the deflection ring 129 through the pin shaft 126. In this process, the microbial fertilizer spray head 127 drives the two second rotating shaft rods 1292 to rotate inside the deflection ring 129, which serves to support and limit the microbial fertilizer spray head 127, preventing it from coming off the deflection ring 129 or being stuck and unable to rotate. As the microbial fertilizer spray head 127 continues to deflect, the deflection ring 129 drives the two first rotating shaft rods 1291 to rotate inside the two U-shaped frames 124. During this process, the pin shaft 126 at the top of the microbial fertilizer spray head 127 serves as the center of rotation, driving the microbial fertilizer spray head 127 and the nozzle 128 to make continuous rotation along a 360-degree circular trajectory. The deflection block 125 rotates one revolution, allowing the nozzle 128 to make 360-degree circular rotational motion. The nozzle 128 continuously sprays liquid medicine, making the spray evenly cover the full annular area centered on the connecting seat 121. This method takes into account all angles in front, back, left, and right without the need for manual adjustment. The residence time of the nozzle 128 in each direction is completely consistent. When the nozzle 128 makes circular rotational motion, the microbial fertilizer spray head 127 can drive the medicine guide flexible pipe 1293 to stretch or contract, making the connection between the microbial fertilizer spray head 127 and the branch pipe 1294 flexible. This does not affect the conductivity between the microbial fertilizer spray head 127 and the branch pipe 1294 during the movement of the nozzle 128. When the height of the two microbial fertilizer spreading assemblies 12 at the bottom of the spreading extension rods 11 is adjusted, the first motor 501 is controlled to work to drive the lead screw 502 to rotate. In the rotating process of the lead screw 502, the nut 503 drives the two connecting blocks 6 to move upwards through the fixing seat 504. The connecting blocks 6 drive the synchronous adjusting assembly 10 and the connecting seat 121 to move upwards through the spreading extension rods 11. The connecting seat 121 drives the deflector ring 129 to move upwards through the U-shaped frame 124 and the first rotating shaft rod 1291. The deflector ring 129 drives the microbial fertilizer nozzle 127 and the nozzle 128 to move upwards through the two second rotating shaft rods 1292. In the process, the fixing seat 504 drives the two sliding blocks 505 to slide in the two sliding grooves 8. The sliding grooves 8 limit the sliding blocks 505, improve the stability of the vertical movement of the microbial fertilizer spreading assembly 12 driven by the fixing seat 504 and the spreading extension rod 11, and can further adjust the height of the nozzle 128 in the microbial fertilizer spreading assembly 12, facilitate the spreading and fertilization of plants with different heights, and the connecting pipe 134 is designed to be flexible, which will not affect the conduction work between the connecting pipe 134 and the liquid guide pipe 135 in the up-down movement of the spreading extension rod 11.
