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.

The invention discloses a manufacturing method of a large-grain fertilizer composition with low cost. The manufacturing method comprises the following steps of A, material mixing, namely uniformly stirring ammonia water, a mixture prepared from biogas residues and river bottom silt according to the mass ratio of 5:1, calcium superphosphate, plant ash, potassium sulfate, animal oil and fat and seaweed meal, and then, adding the stirred mixture into a heating reaction kettle; B, heating and pressurizing, namely controlling the heating temperature of the reaction kettle at 200-300 DEG C, and meanwhile preserving heat and pressure for 15-20 minutes after increasing 1.6 pressures to obtain fused slurry for later use; C, preparation of the large-grain fertilizer composition with low cost, namely injecting the fused slurry into a mould, carrying out water cooling, and demoulding to from the large-grain fertilizer composition with low cost, wherein the diameter of the large-grain fertilizer composition with low cost is 5-8cm; and D, coating preparation, namely soaking the obtained large-grain fertilizer composition with low cost by using tung oil to form a film, and packaging. The manufacturing method disclosed by the invention is simple; and the prepared large-grain fertilizer composition with low cost is simple in proportioning, long in fertilizer effect as well as convenient and rapid in fertilizing.
Description
[0001] Technical field: [0002] The invention relates to the technical field of fertilizers, in particular to a method for manufacturing a low-cost large-grain fertilizer composition. [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, there is a need for a manufacturing method of a low-cost large-grain fertilizer compo...
