[0002] Fertilizer spreaders are an important type of agricultural machinery, mainly used to spread fertilizer evenly on farmland to improve fertilization efficiency, reduce labor intensity, and help improve soil structure. Fertilizer spreaders can be divided into many types according to their functions and structural characteristics. For example, there are fertilizer spreaders suitable for solid fertilizers, and there are also fertilizer spreaders specifically for liquid fertilizers. Some advanced fertilizer spreaders also have the function of adjusting the amount of fertilizer spread, the speed of fertilizer application, and the distribution range of fertilizer to meet the fertilization needs of different crops and soils.
