Embodiment 1

[0018] A preparation process for slow-release agricultural fertilizer, its components include:

[0019] (1) Mix the active ingredients of the fertilizer with decomposed cow dung, plant ash, and general calcium as base fertilizer and compound fertilizer. The content of each component of the active ingredients is: 30% decomposed cow dung, 40% plant ash, and 10% general calcium. Base fertilizer and 20% compound fertilizer;

[0020] (2) Add the binder to water to make a mixed solution, the mixing ratio of binder and water is 1:9, the binder is biological binder, and then mix the solution with the active ingredients of agricultural fertilizer to make the fertilizer effective The ingredients are wet and thick, and they are granulated in a granulator to make the active ingredients of agricultural fertilizers into granules with a particle size of 0.5mm;

[0021] (3) In step (2), the agricultural fertilizer granules are dried in a dryer at a temperature of 50°C for 50 minutes;

Abstract

The invention discloses a preparation process of a slow release farming fertilizer. In step (1), the content of effective components is as follows: 30% of decomposed cow dung, 40% of plant ash, 10% of superphosphate base fertilizer and 20% of compound fertilizer, and with the components, nutriment for sufficient growth of seedlings can be provided; in step (2), the mixing proportion of an adhesive and water is 1:9, and in the proportion, effective components of the fertilizer can be bonded into clusters, without affecting release of the fertilizer in later period, the adhesive in step (2) is a biological adhesive, and the adhesive does not have toxic action on crops, and can effectively bond effective components of the fertilizer into clusters so as to be convenient for wrapping of macromolecule materials; and in step (6), the smearing method of surface grease is as follows: fertilizer particles are vibrated in a screening machine, and then grease is sprayed to the surface of fertilizer particles via a spraying device. The method can be used for quickly smearing grease on the surface of fertilizer particles.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a preparation process of slow-release agricultural fertilizer. Background technique [0002] my country is a big agricultural country, and agriculture is a pillar industry in our country. In order to increase the productivity of agriculture, agricultural personnel generally use more fertilizers to stabilize and increase production. This extensive fertilization method will cause a large amount of fertilizer loss while increasing production, which will reduce the utilization rate of fertilizers and increase agricultural costs. Contents of the invention [0003] A preparation process for slow-release agricultural fertilizer, its components include: [0004] (1) The active ingredients of agricultural fertilizers are mixed with decomposed cow dung, plant ash, and common calcium as base fertilizer and compound fertilizer; [0005] (2) Add the binder into water to make a mixed solution, ...
