Problems solved by technology

[0005] In addition, the low utilization rate of chemical fertilizers also has a great relationship with the composition of chemical fertilizers. The common fertilizers currently used have the following problems: 1. Since they are mainly nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers or three-element compound fertilizers, they cannot be fully absorbed by plants. It is easy to cause soil compaction; 2. The growth of crops, especially the growth of vegetables and fruits, urgently needs medium and trace elements, but it is difficult for ordinary fertilizers to supplement multiple trace elements at the same time (difficult to use evenly), and can only contain 2-3 kinds of trace elements Elements, even if the fertilizer contains a variety of trace elements, it is difficult for plants to absorb it in a balanced manner, and it may even have a bad effect (produce fertilizer damage)

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a highly concentrated polypeptide-ammonium polyphosphate trace element liquid chelated fertilizer and a preparation method thereof, belonging to the technical field of chemical fertilizers. Background technique [0002] Chemical fertilizers provide the nutrients needed for crop growth. The macronutrients nitrogen, phosphorus, and potassium in the soil usually cannot meet the needs of crop growth. It is necessary to use fertilizers containing nitrogen, phosphorus, and potassium to make up for it. At present, due to the application of traditional chemical fertilizers The sharp increase in the dosage has led to the increasingly serious lack of trace elements in the soil. The trace elements removed from the soil by crops should be returned to the soil as soon as possible to maintain the balance of various elements in the soil. In some high-yielding fields, due to the l...
