[0002] Soybeans require sufficient nitrogen, phosphorus, potassium and other nutrient elements, as well as medium and trace elements such as copper, molybdenum, boron, zinc, and iron during the entire growth period to ensure normal growth. Although soybeans have the function of nitrogen fixation and can utilize nitrogen in the air, the nitrogen fixation amount of rhizobia is limited and cannot meet all the growth needs of soybeans. Especially during the flowering and pod-setting period, the demand for nutrients by soybeans reaches a peak. At this time, if the nutrients in the soil are insufficient, it will lead to incomplete filling of soybean grains, thus reducing the yield. Therefore, it is very necessary to supplement the nutrients required for soybean growth by topdressing and spraying foliar fertilizers;

[0003] When topdressing soybeans, generally, the soil around the soybean plants is dug open manually, and then fertilization is carried out. After the fertilization is completed, the soil is covered, and the topdressing is completed. However, this topdressing method is only applicable to small-area planting, consuming a large amount of manpower and being time-consuming and laborious; there is also a device for large-area topdressing that can broadcast fertilizers beside soybean plants, but it does not have the ability to dig and cover soil, and can only sprinkle fertilizers on the soil surface, resulting in poor fertilizer absorption effect.
