The fertilizer has the advantages of simple components, high nutrient content, quick fertilizer effect, strong fertilizer effect, acid-base reaction of certain fertilizers, no organic matter and no soil improvement and fertilization effects. Statistically, the effect of fertilizers accounts for about 30% of various agricultural production-increasing measures. China can cultivate and live 22% of people in 7% of cultivated land in the world, and the fertilizer plays a role in lifting. The low fertilizer utilization rate is always a problem in agricultural fertilization in China. The cost expenditure in terms of fertilizer purchase per hectare per year is 1005 yuan per year on average, calculated as the area of the cultivated land. In the process of applying the fertilizer, the fertilizer is applied by roots, the fertilizer is applied by a bottom fertilizer, the fertilizer is sprayed by leaves and the fertilizer is applied by flushing, wherein the efficiency of flushing the fertilizer is highest and the labor is saved the most. However, many existing fertilizers have poor solubility, and known fertilizer particles are easy to sink to the water bottom in the flushing application process, so that the flushing application effect is influenced, so that a plurality of places are caused, the fertilization is not uniform, if the fertilizer particles are applied along with water, the fertilizer deposition at a water inlet is easy to cause more fertilizer deposition, and the fertilizer particles are excessively applied to soil and crops, so that the soil is over-fertilized, the pH value is far away from neutral, and the soil pollution or the crops are burned. Therefore, how to design and produce a fertilizer suitable for water flush application and reduce the manpower input in the fertilization process becomes a technical problem to be solved urgently. Therefore, by utilizing the principle that oil content is rapidly diffused on the water surface, different fertilizers are layered to form granules with a multilayer structure containing soybean oil, the soybean oil in the fertilizer powder can be rapidly diffused in the dissolving process of the fertilizer powder, the soybean oil is adhered and fixed with the fertilizer powder particles, and the fertilizer powder particles can be rapidly brought into the field by water and an oil film due to the extremely easy diffusion of the oil content during irrigation, so that the aims of uniformly applying various fertilizers and reducing the manual input of the fertilizer application are fulfilled.
