[0057] The fertilization method of the landscaping fertilization equipment of the present invention includes the following specific steps: S1: Equipment Positioning and Preparation The equipment is transported to the landscaping work area. The main switch is turned on, and the solar panel 702 begins absorbing solar energy and converting it into electrical energy, which is stored in the energy storage battery to power each unit of the equipment. Based on the plant distribution in the landscaping area, operational parameters, including fertilization location, fertilization depth, fertilization amount, and soil conditioner dosage, are input via a remote control terminal, or a preset operating program is invoked.

[0058] The drive wheel assembly 704 on the walking frame 703 is rotated to move the equipment to the target fertilization location. The level adjustment mechanism is activated, and the level sensor detects the level status of the adjustment platform 205. If the adjustment platform 205 is tilted, the fine-tuning cylinder is activated to adjust the adjustment platform 205 to a level state, ensuring accurate subsequent operations and completing the equipment positioning and preparation work.

[0059] S2: Soil Pretreatment The high-speed motor 502 of the soil pretreatment unit is started via a remote control terminal. The high-speed motor 502 drives the soil-breaking blade 503 to rotate at a high speed of 2500 rpm. The telescopic hydraulic rod 302 is extended at a speed of 5 mm / s, which drives the pre-fixed arc plate 401 to contact the soil around the plant roots, pre-fixing and limiting the pretreatment area. The elastic limiting block 402 presses the soil surface under the elastic force of the return spring 403 to prevent soil displacement during operation.

[0060] Next, the telescopic hydraulic rod 302 continues to extend, and the arc-shaped clamping plate 303 further clamps and positions the soil, ensuring the breaking area is firmly fixed. Simultaneously, the positioning arc strip 601 rotates to fit the soil surface under the resistance of the soil, precisely delineating the breaking area. Protected by the protective shell 501, the breaking blade 503 loosens the soil, breaking up the compacted soil layer. The breaking depth is adjusted according to the distribution of plant roots, generally 10-20cm, creating favorable conditions for fertilizer penetration. After the breaking operation is completed, the high-speed motor 502 is stopped rotating.

[0061] S3: Precision Fertilization Operation The drive motor 202 of the lifting and adjusting unit is started by the remote control terminal. The drive motor 202 drives the transmission pulley 203 to rotate, and the transmission pulley 203 drives the transmission belt 204 to move, thereby adjusting the height of the adjusting platform 205 so that the precision fertilization unit reaches the pre-set fertilization height. The fertilization height is adjusted according to the plant type. The fertilization height for trees is 5-10cm above the ground, and the fertilization height for shrubs is 3-5cm above the ground.

[0062] The push cylinder 101 extends and retracts at a speed of 8 mm / s, driving the transmission rack 102 to move linearly. The transmission rack 102 drives the meshing transmission gear 105 to rotate, which in turn drives the folding connecting rod 106 to unfold, allowing the annular fertilizer applicator 107 to fit against the soil surface around the plant roots. Fertilizer solution is injected through the infusion port on the annular fertilizer applicator 107. The fertilizer solution flows through the infusion chamber inside the annular fertilizer applicator 107 into the drainage channel of the permeation sponge pad 108. After the permeation sponge pad 108 contacts the soil, it evenly permeates the soil surface. The flow rate of surface fertilization is adjusted by the flow regulating valve on the annular fertilizer applicator 107, with a range of 10-50 mL / min, set according to the plant's nutrient requirements.

[0063] Simultaneously, the transmission rack 102 drives the linkage block 103 to move synchronously. The linkage block 103 pushes the push rod of the fertilizer injector 104, causing the needle of the fertilizer injector 104 to insert into the deep soil layer to a depth of 20-30 cm, precisely injecting the fertilizer solution. This achieves a dual fertilization mode combining surface penetration fertilization and deep injection fertilization, meeting the absorption needs of roots at different depths. A pressure sensor at the needle of the fertilizer injector 104 monitors the injection pressure in real time. When the pressure exceeds a preset threshold, it feeds back to the control system, reducing the thrust of the push cylinder 101 to prevent needle damage; when the pressure is below the preset threshold, it increases the thrust of the push cylinder 101 to ensure effective injection of the fertilizer solution into the deep soil layer.

[0064] S4: Soil Improvement Treatment After precision fertilization is completed, the dual-shaft drive motor 804 of the soil improvement unit is activated via a remote control terminal. The dual-shaft drive motor 804 drives the rotating shaft 803 to rotate at 800 rpm, which in turn drives the soil loosening and mixing blade 807 to rotate, mixing the fertilized soil for 3-5 minutes to ensure uniform mixing of fertilizer and soil and improve fertilizer absorption efficiency. During the rotation of the soil loosening and mixing blade 807, the scraper blade 806 on the cleaning ring 805 adheres to the surface of the soil loosening and mixing blade 807 under centrifugal force, scraping away and cleaning the soil adhering to the surface of the blade in real time, ensuring effective soil loosening and mixing.

[0065] Soil conditioner (such as organic fertilizer, microbial inoculant, etc.) is added through the feed inlet 902 of the raw material storage tank 901. The amount of soil conditioner added is set according to the soil conditions and plant needs, generally 50-100g per square meter. The reduction drive motor 905 is started, which drives the spiral stirring rod 904 to rotate. Multiple spiral stirring rods 904 work together to evenly mix the soil conditioner for 2-3 minutes. The mixed conditioner is then conveyed through the conveying pipe 906 to the diversion plate 907. After being diverted by the diversion plate 907, it enters the arc-shaped spraying plate 908, and is then evenly sprayed onto the mixed soil through the spraying holes 909 on the arc-shaped spraying plate 908, thereby improving the physical and chemical properties of the soil and promoting plant root growth.

[0066] S5: Work completed and equipment reset After fertilization and soil improvement operations are completed, the power mechanisms, including the high-speed motor 502, drive motor 202, push cylinder 101, dual-shaft drive motor 804, and reduction drive motor 905, are sequentially shut down via a remote control terminal. The push cylinder 101 is then retracted, causing the transmission rack 102, transmission gear 105, and folding connecting rod 106 to reset, and the annular fertilizer applicator 107 and fertilizer injector 104 to return to their initial positions.

[0067] The telescopic hydraulic rod 302 is retracted, causing the pre-fixed arc plate 401, arc-shaped clamp 303, and elastic limit block 402 to reset. The positioning arc strip 601 returns to its initial position under its own elasticity. The drive wheel set 704 is rotated to move the equipment to the next fertilization position, and the above steps are repeated for continuous operation. Once all fertilization operations are completed, the equipment is moved to the designated storage area, the main switch is turned off, and the current fertilization cycle is completed.
