The fertilizer has high utilization rate and the yield of crops is increased.

Description

technical field

[0001] The invention relates to the technical field of blended fertilizers. Background technique

[0002] The blended fertilizers currently on the market are mostly ordinary types, which are made of large-grain urea, granular phosphate fertilizer, and granular potassium fertilizer in a certain proportion. In the process of processing, some trace elements will not be added, and its effect is only ordinary. Type, basically non-functional. If trace elements are added, they are basically extruded particles of trace elements, which have certain functionality, but the use effect is not high, and the waste is serious.

[0003] Functional fertilizers, also known as multifunctional fertilizers, are one of the important research and development directions of new fertilizers in the 21st century. They are fertilizers that combine crop nutrition with other factors that limit crop yields. increase production efficiency. The research and production of multifunctional fer...
