[0002] Precision fertilization helps the growth of crops and the absorption of nutrients, increases the yield per mu of crops, improves the quality of crops, increases soil fertility and economic benefits. Therefore, scientific and effective fertilization is one of the important means to ensure food production and sustainable development. There are two current fertilization methods: manual and machine spreading. Traditional fertilization generally spreads granular fertilizers on the surface layer, which cannot quantitatively and accurately deliver fertilizers to the pits, and the fertilization effect is poor. It is easy for fertilizers to be stored on the surface, which affects the utilization rate of fertilizers and is not conducive to the growth of crop roots. In addition, the accumulation of fertilizers is easy to condense with soil blocks on the surface, causing soil damage. When applying fertilizers, the existing fertilization device relies on spreading and large-scale fertilization. Some fertilizers lose their function and cannot fully provide the required nutrients for crops. The utilization rate between fertilizers and crops is not high. At the same time, the existing fertilization device cannot adjust the dosage of different types of fertilizers at any time, resulting in the need for users to perform manual regulation, which wastes time and affects the fertilization process.
