Abstract

The invention discloses a manufacturing method of a micro-particle multiple seaweed fertilizer, relates to the field of fertilizer production. More particularly, the manufacturing method of the micro-particle multiple seaweed fertilizer comprises the following steps: adding nitrogen phosphorus and potassium, mineral fulvic potassium and trace elements to a seaweed extract, forming a liquid fertilizer having a solid content of 20-35%, and manufacturing the liquid fertilizer into the micro-particle multiple seaweed fertilizer by using a centrifugal spray-drying technique. The manufacturing method comprises the following steps in order: (1) the compounding of the seaweed extract and trace elements; (2) the compounding of the seaweed extract with mineral potassium fulvic acid; and (3) centrifugal spray drying of the compounded material to produce the micro-particle multiple seaweed fertilizer. According to the invention, the problems of insufficient total nutrients, easy fermentation and deterioration and short storage of natural seaweed extract in liquid state are solved, and the manufacturing method has the advantages of stable physical and chemical properties, sufficient nutrients,good application effect and convenience of application.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a liquid fertilizer with a solid content of 20-35% after the seaweed extract is added with nitrogen, phosphorus and potassium, ore-sourced potassium fulvic acid and trace elements, and is dried by centrifugal spray drying technology. , making the liquid fertilizer into micro-particle multi-component seaweed fertilizer. Background technique [0002] The seaweed extract is extremely rich and balanced in nutrition, contains many endogenous growth hormones that are incomparable to land plants, and has the advantages of improving crop resistance, improving the soil micro-ecological environment, and being naturally pollution-free, but the natural seaweed extract has insufficient total nutrients , the liquid state is easy to ferment and deteriorate, and it is not suitable for long-term storage; in view of the above shortcomings, the present invention proposes a method for manufactur...
