[0015] Base and topdressing fertilization refers to a fertilization technique that scientifically allocates the proportion of base fertilizer and topdressing in the total fertilizer application based on crop type, soil fertility, yield target, and climatic conditions. By rationally combining base fertilizer (applied before sowing or transplanting) and topdressing (applied in stages during the growth process), it achieves efficient nutrient supply and improves crop yield and quality. Distinguishing between base fertilizer and topdressing: Base fertilizer: Application time: Applied in conjunction with tillage before sowing or transplanting. Fertilizer type: Mainly organic fertilizers (such as manure, compost, and green manure), supplemented with appropriate chemical fertilizers (such as phosphate and potassium fertilizers). Function: Provides basic nutrients for the entire crop growth cycle, improves soil structure, and promotes root development. Proportion: Usually accounts for 50%-60% of the total fertilizer application, adjusted according to crop and soil conditions. Topdressing: Application time: Applied in stages during key crop growth periods (such as tillering, heading, and fruit enlargement). Fertilizer type: Mainly fast-acting chemical fertilizers (such as nitrogen and potassium fertilizers), supplemented with foliar fertilizers. Function: To supplement insufficient base fertilizer, meet the peak nutrient requirements of crops at different stages, and avoid nutrient waste. Proportion: Typically accounts for 40%-50% of total fertilizer application, with the specific proportion adjusted according to crop needs. Implementation Principles: Crop Demand Oriented: High-yield crops (e.g., wheat, rice): Base fertilizer proportion can be reduced to 60%-70%, while topdressing proportion can be increased to 30%-40% to meet the needs of rapid growth. Low-yield crops (e.g., legumes): Base fertilizer proportion can be increased to 70%-80%, reducing the number of topdressing applications. Soil Condition Adjustment: Fertile Soils: Reduce base fertilizer proportion, increase topdressing flexibility. Poor Soils: Increase base fertilizer proportion to ensure basic nutrient supply. Climatic Factors: Arid Regions: Appropriately increase base fertilizer proportion to reduce reliance on topdressing. Rainy Regions: Topdressing should be applied in multiple applications to avoid nutrient loss. Advantages: Improved Fertilizer Utilization: Reduces nutrient fixation and loss through phased application, promoting crop health: Meets the needs of each growth stage, avoiding excessive vegetative growth or premature aging. Environmental Benefits: Reduces soil and water pollution caused by excessive fertilization. Base fertilizer and topdressing ratio is one of the core technologies of scientific fertilization. By rationally allocating the ratio of base fertilizer to topdressing, precise nutrient supply is achieved, ensuring crop yield and quality while promoting sustainable agricultural development. Implementation requires flexible adjustments based on specific crop, soil, and climate conditions to achieve optimal results.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figures 1-4 As shown, this embodiment provides an adjustable base-topdressing ratio fertilization device, including a protective box 2, a fertilizer box 3 symmetrically installed inside the protective box 2, a fertilizer shovel 6 connected to the bottom of the fertilizer box 3, a fertilizer hole opened at the bottom of the fertilizer shovel 6, a central shaft 7 rotatably connected inside the fertilizer box 3, a movable plate 9 fixedly connected to the central shaft 7, one end of the movable plate 9 away from the central shaft 7 being slidably connected to the inner wall of the fertilizer box 3, a fixed plate 8 fixedly connected to the inner wall of the fertilizer box 3, the other end of the fixed plate 8 being slidably connected to the central shaft 7, an adjustment mechanism provided above the central shaft 7, and the adjustment mechanism being rotatably connected to the top of the fertilizer box 3.

[0019] In use, fertilizer is added to the fertilizer box 3 and then dropped into the soil using the fertilizer shovel 6. When the ratio needs to be changed, the adjusting mechanism drives the central shaft 7 to rotate, which in turn moves the movable plate 9. The movable plate 9 and the fixed plate 8 divide the fertilizer box 3 into two areas, corresponding to base fertilizer and topdressing respectively. Fertilizer is added to different areas at different stages, making operation simple and convenient. This utility model features an integrated design that reduces space occupation and adapts to farmland operating environments. The protective box 2 protects the internal mechanical structure from soil and impurities, extending the equipment's lifespan. The central shaft 7 drives the movable plate 9 and the fixed plate 8 to work together to dynamically adjust the cross-sectional area of ​​the fertilizer channel, achieving precise control of the base fertilizer and topdressing ratio.

[0020] Further refining the design, the adjustment mechanism includes a knob 4, which is mounted on the central shaft 7. The top of the knob 4 passes through the fertilizer box 3 and is rotatably connected to the top of the fertilizer box 3. An elastic component is installed inside the knob 4 to reset it after vertical movement. The knob 4 is directly connected to the central shaft 7, and its rotation drives the movable plate 9 to adjust the fertilizer base ratio, making operation simple and intuitive. The elastic component ensures that the knob 4 automatically resets after adjustment, maintaining the stability of the adjusted position and preventing ratio misalignment due to vibration or external force.

[0021] Further refining the design, the elastic component includes a spring 15 sleeved on the outside of the central shaft 7. A limiting rod 13 is fixedly connected to the top of the central shaft 7. A retaining ring 16 is fixedly connected to the inner wall of the knob 4, located on the outside of the central shaft 7. One end of the spring 15 is fixedly connected to the retaining ring 16, and the other end of the spring 15 is fixedly connected to the limiting rod 13. The spring 15, sleeved on the outside of the central shaft 7 and fixed to the limiting rod 13 by the retaining ring 16, prevents the spring 15 from twisting or deforming, ensuring uniform transmission of elastic force. Its fixed connection to the central shaft 7 restricts the axial displacement of the spring 15, ensuring the long-term reliability of the elastic component.

[0022] To further refine the design, symmetrical limit grooves 14 are formed on the inner wall of the knob 4, and both ends of the limit rod 13 extend into the limit grooves 14 and are slidably connected to them. When the knob 4 moves up and down, the limit rod 13 slides along the limit grooves 14 to ensure accurate movement trajectory and avoid deviation affecting adjustment accuracy.

[0023] Further refining the design, a first gear 11 is fixedly connected to the outer wall of knob 4. The first gear 11 meshes with a second gear 12. When the first gear 11 and the second gear 12 are engaged, knob 4 cannot rotate. Moving knob 4 upwards disengages the first gear 11 from the second gear 12, allowing adjustment by rotating knob 4. Engaging the first gear 11 with the second gear 12 locks knob 4, preventing accidental changes in the ratio. Moving knob 4 upwards disengages it, unlocking it for safe adjustment. This mechanical locking prevents ratio changes during operation, ensuring fertilization accuracy.

[0024] Further refining the design, a partition 10 is fixedly connected to the inner wall of the fertilizer bin 3, and the second gear 12 is fixedly connected to the top surface of the partition 10. The partition 10 provides a stable mounting surface for the second gear 12, while also separating the internal space of the fertilizer bin 3 to prevent fertilizer from entering the gear transmission area, thus avoiding jamming or wear. The partition 10 enhances the local strength of the top of the fertilizer bin 3, bearing the force exerted when the knob 4 is adjusted.

[0025] The design is further refined: a pointer 5 is fixedly connected to the top of knob 4, and a scale is marked on the top of fertilizer bin 3. The adjustment ratio is determined by pointing pointer 5 to the scale. The pointer 5, in conjunction with the scale, visually displays the current base fertilizer ratio, allowing users to accurately set parameters without prior experience. The scale markings quantify the adjustment steps, improving operational consistency among different users and adapting to the needs of large-scale agricultural production.

[0026] The design is further refined: a traction frame 1 is fixedly connected to the outside of the protective box 2, and the traction frame 1 is detachably connected to the external power unit. This detachable connection allows the traction frame 1 to be compatible with various agricultural machinery, expanding the equipment's applicability. Mechanized traction replaces manual pushing, increasing fertilization speed and coverage area while reducing labor intensity. The detachable design facilitates the replacement of the traction frame 1 or overall equipment maintenance, extending its service life.
