[0002] In the process of agricultural planting, fertilization is an important means to promote the growth and development of crops and increase yields. However, if the fertility is excessive or insufficient, it will have an adverse effect on the growth and development of crops. Therefore, scientific fertilization is a necessary measure to improve the efficiency of agricultural production. There are many ways to fertilize, and fertilization can be carried out at different stages of agricultural planting.

[0003] However, most of the current fertilization devices use tools to bury fertilizers in the soil manually, which makes it difficult to control the amount of fertilizer filled in each time, easily leading to excessive or insufficient effort, and it is inconvenient to break up the lumps in the fertilizer, which will cause the lumps of fertilizer to dissolve poorly in the soil, thereby resulting in poor fertilization effect of the land.
