Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fertilization, in particular to a corn planting and fertilizing device. BACKGROUND

[0002] Among the many growth management links of corn, scientific fertilization is the core factor affecting its yield and quality. Modern agronomic studies have shown that different types of fertilizers have their own optimal fertilization depth due to the differences in nutrient release characteristics and crop root distribution. For example, shallow fertilization is beneficial for seedling absorption, while deep fertilization can promote root penetration, improve fertilizer utilization rate and crop stress resistance. However, the traditional fertilization operation mode, including manual scattering and early mechanical fertilization, generally has the problems of single fertilization depth and uneven fertilizer distribution, which cannot meet the demand of precise layered fertilization, resulting in large waste of fertilizer, low utilization rate, and even causing soil compaction and environmental non-point source pollution.

[0003] At present, the mechanical fertilization devices commonly seen in the market have exposed many defects in actual application. First, there are serious deficiencies in the precision and adaptability of fertilization. Most of the devices use fertilization furrowers with fixed depth, which is difficult to adjust flexibly during operation once the depth is set. This makes the same device unable to adapt to different fertilizer varieties and different agronomic requirements at different growth stages, resulting in rigid fertilization strategy. If farmers want to achieve layered fertilization, they often need to operate multiple times or purchase different equipment, which not only greatly increases the labor intensity and production cost, but also reduces the operation efficiency, and cannot meet the demand of modern agriculture for precision and individualized fertilization.

[0004] Secondly, the fertilization mode of the existing device is extensive, and the mixing effect of fertilizer and soil is poor. Many devices only achieve the "delivery" of fertilizer to the soil, but not the "fusion". The fertilizer is often concentrated in the form of strips or dots in the soil, and cannot be fully and uniformly mixed with soil particles. This concentrated fertilizer environment can easily cause "root burning" and "seedling burning". At the same time, due to the small contact area with the soil surface, the release and diffusion efficiency of nutrients is low, and the root absorption is uneven, which seriously restricts the play of fertilizer efficiency. Although some devices try to add stirring function, their structure is complex, and they mostly rely on external power, which increases the manufacturing cost and failure rate, and the uniformity and synchronicity of stirring still need to be improved.

[0005] Finally, the existing fertilization device has weak control ability of soil breaking and depth stability. The design of the furrower is sensitive to soil conditions. When encountering hard, compacted or root-winding soil, it is easy to cause soil accumulation, blockage or unstable depth, resulting in uneven fertilization depth. This instability directly destroys the uniformity of fertilization operation, making the growth of corn plants uneven, affecting the yield of the group, and in addition, the large breaking resistance also leads to high traction load and increased energy consumption.

[0006] The present application aims to solve the technical problems in the prior art, and provides a corn planting and fertilizing device. SUMMARY
