[0002] In the process of agricultural modernization, precision fertilization technology as a key means to improve crop yield and quality, is attracting more and more attention. With the development of science and technology, the automation and intelligentization of fertilization devices in agricultural production are constantly improved. Water-soluble fertilizer is widely used in modern agriculture because of its fast dissolution and high absorption efficiency. The deep fertilization device matched with it has become a research hotspot in the field of agricultural machinery.

Most of the devices use traditional scattering or superficial fertilization methods. In the fertilization process, the amount of fertilizer cannot be accurately controlled according to the motion state of the device, which easily leads to uneven fertilization. Moreover, the effect of soil breaking and mixing of fertilizer and soil of these devices is not ideal, which affects the absorption efficiency of water-soluble fertilizer.

[0004] The fertilization steps of the prior art are usually as follows: first, the water-soluble fertilizer is loaded into the storage box, and then the device is moved in the field by manual or mechanical driving device. During the movement, the fertilizer flows from the storage box to the fertilization area through the transfer box.

[0005] In the fertilization process of the prior art, due to the lack of effective sensing device to judge whether the device is in motion state, the amount of fertilizer cannot be accurately controlled according to the motion state of the device, which easily leads to the problem of over-spraying of fertilizer when the device stays at one place, resulting in uneven spraying. In addition, the soil breaking and loosening function of the existing device is not perfect, which cannot deeply break and fully loosen the soil, so that the water-soluble fertilizer cannot be well mixed with the soil, affecting the absorption effect of the fertilizer and reducing the agricultural production efficiency.
