Embodiment 1

[0033] The process steps of mixing mineral humic acid and livestock manure to produce humic acid organic fertilizer are as follows:

[0034] 1. Pretreatment

[0035] Including the following steps:

[0036] Step 1. Evenly sprinkle the fermented microorganism strains on the fresh livestock and poultry manure. Fresh livestock and poultry manure refers to the livestock and poultry manure in the cesspool of the farm. During the sprinkling process, when the water content of the fresh livestock and poultry manure is greater than 70%, , during the sprinkling process, the mass ratio of fresh livestock and poultry manure to fermented microbial strains is controlled to be 1000:1, and the sprinkling frequency is once every 2 days;

[0037] Step 2. Record the first splashing fermentation microbial strain as the first day, and the fermentation time is 1 to 7 days. After the fermentation is over, use a dry-wet separator to dehydrate or add auxiliary materials to check the water content of l...

Embodiment 2

[0047] The process steps of mixing mineral humic acid and livestock manure to produce humic acid organic fertilizer are as follows:

[0048] 1. Pretreatment

[0049] Including the following steps:

[0050]Step 1. Sprinkle fermented microorganism strains evenly on fresh livestock and poultry manure. Fresh livestock and poultry manure refers to the livestock and poultry manure in the cesspool of the farm. During the sprinkling process, when the water content of fresh livestock and poultry manure is 50%~ 70%, during the sprinkling process, control the mass ratio of fresh livestock and poultry manure to fermented microbial strains to be 1000:2, and the sprinkling frequency is once every 3 to 4 days;

[0051] Step 2. Record the first splashing fermentation microbial strain as the first day, and the fermentation time is 1 to 7 days. After the fermentation is over, use a dry-wet separator to dehydrate or add auxiliary materials to check the water content of livestock and poultry man...

Embodiment 3

[0061] The process steps of producing humic acid organic fertilizer by mixing mineral source humic acid and livestock and poultry manure are as follows: 1. Pretreatment

[0062] Including the following steps:

[0063] Step 1. Sprinkle fermented microorganism strains evenly on the fresh livestock and poultry manure. Fresh livestock and poultry manure refers to the livestock and poultry manure in the cesspool of the farm. During the sprinkling process, when the water content of the fresh livestock and poultry manure is less than 50%. , during the sprinkling process, the mass ratio of fresh livestock and poultry manure to fermented microbial strains is controlled to be 1000:3, and the sprinkling frequency is once every 5 to 6 days;

[0064] Step 2. Record the first splashing fermentation microbial strain as the first day, and the fermentation time is 1 to 7 days. After the fermentation is over, use a dry-wet separator to dehydrate or add auxiliary materials to check the water con...

Abstract

The invention discloses a process method for producing a humic acid organic fertilizer by mixing mineral source humic acid and livestock and poultry manure, which comprises pretreatment and high-temperature activation. The pretreatment comprises the following steps that: step 1, s fermentation microbial strain is evenly scattered on fresh livestock and poultry manure, and in the scattering process, the mass ratio of the fresh livestock and poultry manure to the fermentation microbial strain is 1000: (1-3), and the scattering frequency is one time every 2-6 days; and step 2, the day when the fermentation microbial strain is sprayed for the first time is recorded as a first day, fermentationlasts for 1-7 days, the water content of the livestock and poultry manure is adjusted to 40%-60% after the fermentation is finished, and pretreated livestock and poultry manure is obtained after pretreatment. The content of organic matters in the organic fertilizer produced by the method is high and reaches 50% or above, the content of active humic acid is high and reaches 5% or above, the contents of nitrogen, phosphorus and potassium are high and reach 5% or above, the water content of the organic fertilizer is lower than 25%, and the organic fertilizer meets the national standard.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, and more specifically relates to a process for producing humic acid organic fertilizers by mixing mineral source humic acid and livestock manure. Background technique [0002] Livestock and poultry manure mainly refers to a type of rural solid waste produced in the livestock and poultry breeding industry, including pig manure, cow manure, sheep manure, chicken manure, duck manure, etc. In the livestock and poultry breeding industry, a large amount of livestock and poultry manure will be produced. The direct discharge of livestock and poultry manure will pollute the environment, and livestock and poultry manure contains a variety of effective resources. Usually, livestock and poultry manure is used to produce organic fertilizers. In the process of mixing mineral humic acid with livestock and poultry manure to produce organic fertilizers, fresh manure is mixed first. Mineral humic acid ...
