Problems solved by technology
Traditional fertilizers are all in the form of fine particles, usually spherical particles with a size of 3-5mm. However, traditional fertilizer particles are too small, especially when fertilizing by hand, it is difficult to control the amount, so fertilization is time-consuming and laborious.
The fertilizer with too small particles has a small degree of slow release and short fertilizer effect time.

Abstract
The invention discloses a manufacturing method of bulky compound fertilizer. The method includes the following steps of A, mixing materials, wherein ammonium sulfate, ammonium bicarbonate, powdered rock phosphate, seaweed meal, monopotassium phosphate, animal fat and ammonium molybdate are evenly stirred and added into a heating reaction still; B, conducting heating and pressurizing, wherein the heating temperature of the reaction still is controlled to be 200-300 DEG C, meanwhile pressurizing is conducted by 1.6 atmospheric pressure, temperature and pressure are kept for 15-20 min, and then magma is obtained for use; C, preparing the bulky compound fertilizer, wherein a mold is used, the magma is poured into the mold, water cooling and demolding are conducted to form the bulky compound fertilizer, the diameter of the bulky compound fertilizer is 3-5 cm, the mold is formed by integrally connecting a plurality of spherical structures, and a cooling water curtain flows through the outer surface of the mold; D, preparing wrappers, wherein the outer surfaces of the spherical particles obtained in the step C are coated with melted sulfur to form sulfur film with thickness of 2-3 mm; E, conducting packaging, wherein the bulky compound fertilizer obtained in the step D is soaked in heavy oil to form film, and packaging is conducted. The manufacturing method is simple, the manufactured product is simple in ratio, and the fertilizer is long in efficiency time and convenient and rapid to apply.
Description
[0001] Technical field: [0002] The invention relates to the technical field of fertilizers, in particular to a method for manufacturing bulk compound fertilizers. [0003] Background technique: [0004] In today's agricultural production, it is usually necessary to use fertilizers to increase agricultural production. During the fertilization process, it is necessary to use a spreader or fertilization equipment to spread the fertilizer after furrowing. Traditional fertilizers are all in the shape of fine particles, usually spherical particles with a size of 3-5mm. However, the traditional fertilizer particles are too small, especially when fertilizing by hand, it is difficult to control the amount, so fertilization is time-consuming and laborious. The fertilizer with too small particles has a small slow release degree and short fertilizer effect time. For this reason, need to occur a kind of manufacture method simple, the product proportioning of making is simple, and ferti...
