[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. It is one of the material bases of agricultural production. Fertilizers mainly include ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, etc. Water-soluble fertilizers are a type of multi-component fertilizer that can be dissolved in water. They can dissolve quickly in water, are more easily absorbed by crops, and have quick effects. At the same time, they can be used in sprinkler irrigation facilities, which is conducive to the integration of water and fertilizer, and achieves the effect of saving water, fertilizer, and labor. In the past, people used inorganic fertilizers for a long time, which destroyed the acid-base balance of the soil. In some areas, soil compaction and salinization even occurred, greatly reducing soil fertility. Although organic fertilizers do not have the above problems, they have slow fertilizer effects, single nutrients, and no obvious increase in crop yields.
