Description

technical field

[0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a nitro compound fertilizer and a preparation method thereof. Background technique

[0002] Agricultural modernization puts forward higher requirements for chemical fertilizers. In recent years, the production of chemical fertilizers is becoming more and more efficient and compounded. Trace element fertilizers and pesticides are added to them to become multifunctional compound fertilizers. It is convenient to combine the pipeline transportation of fertilizers with irrigation (spray irrigation, drip irrigation), which has the advantages of saving labor and Advantages of improving fertilizer use efficiency.

[0003] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It is very important for ba...
