Problems solved by technology

Due to the inconsistent particle size and shape (large-grained potash fertilizers are extruded into granules, and the particle size is non-spherical and flat), the particle size is inconsistent, and the specific gravity of each particle is greatly different, resulting in serious segregation of the blended fertilizer product. When farmers use it, the plants absorb nutrients unevenly, and in severe cases, it will cause fertilizer damage and reduce crop production.

Abstract

The invention discloses a bulk blended fertilizer, which is formed by mixing compound fertilizer granular materials and other granular materials according to a ratio, wherein all granular materials are spherical and uniform in grain size. Compared with the current bulk blended fertilizer, the bulk blended fertilizer has the advantages that: nitrogen, phosphorus and potassium nutrients are uniform; grain size is uniform and specific weights of grains are approximate; and the phenomenon that the segregation of the product influences the use is avoided.

Description

technical field [0001] The invention relates to an agricultural blended fertilizer, in particular to a novel blended fertilizer and a manufacturing method thereof. Background technique [0002] Various fertilizers are widely used in agricultural production, mainly elemental fertilizers such as urea, ammonium sulfate, potassium chloride, heavy calcium, etc., and multi-component compound fertilizers containing nitrogen, phosphorus, potassium and other nutrients. It is a granular fertilizer made through certain processes and equipment. They can provide various nutrients for plant growth. It has also contributed to the increase in production and income of farmers. [0003] The blended fertilizers currently used in agricultural production are mainly products made by blending large-grain urea, ammonium phosphate and large-grain potassium fertilizers. Due to the inconsistent particle size and shape (large-grain potassium fertilizer is extruded into granules, the particle size is...
