Problems solved by technology

[0002] The production of organic fertilizer needs to adjust the appropriate carbon-nitrogen ratio to ensure microbial decomposition. However, the composting process is a process that releases a large amount of carbon dioxide and other gases. The organic carbon content of the finished organic fertilizer will be greatly reduced compared with the initial material.

preparation example Construction

[0023] The preparation method of the stable carbon source organic fertilizer adopts the following process steps:

[0024] (1) Configuration of basic materials: select cow dung: mushroom dregs: seaweed dregs with a volume ratio of 2:1: (0-0.05), and mix them in stacks with forklifts in proportion. The cow dung mentioned is fresh cow dung or dry dung. Cow dung, mushroom dregs and seaweed dregs are naturally air-dried; said seaweed dregs can be selected from commercially available products.

[0025] The forklift piles up a long pile with a width of 3.5 meters, a height of 0.8 meters, and a length of 160 meters. It is broken and mixed with a self-propelled stacker. The first pass is faster, and the low gear is slow, and the speed is > 1000 rpm; base material.

[0026] (2) Blending and mixing: add decomposing bacteria agent to the basic material, the amount added is 0.05-0.2% of the total weight of the basic material, preferably 0.1% in spring and autumn, 0.05% in summer, and 0.2%...

Embodiment 1

[0033] Embodiment 1: The preparation method of this stable carbon source organic fertilizer adopts the following specific processes.

[0034] (1) The basic material is composed of cow dung: mushroom dregs = 2:1 volume ratio.

[0035] (2) Deployment and mixing: the season is summer, add decomposing bacteria agent to the basic material, the addition amount is 0.05% of the total weight of the basic material, add water to the water content of 55wt%.

[0036] (3) Fermentation: turn the pile when the temperature rises to 58°C, and keep the moisture content at 55wt%; when the temperature reaches 50-70°C again and every time the monitoring reaches 50-70°C, add 5% of the total mass of the basic material % biochar, while adding water to ensure that the water content is 45-55wt%; figure 1 , 2 , 3 shown. The fermentation time is about 18 days to obtain the stable carbon source organic fertilizer. The stable carbon source organic fertilizer has a water content of about 30%, an organic ...

Embodiment 2

[0037] Embodiment 2: The preparation method of this stable carbon source organic fertilizer adopts the following specific processes.

[0038] (1) The basic material is composed of cow dung: mushroom dregs: seaweed dregs = 2:1:0.03 volume ratio.

[0039] (2) Deployment and mixing: the season is autumn, add decomposing bacteria agent to the basic material, the amount added is 0.1% of the total weight of the basic material, and water is added until the water content is 50wt%.

[0040] (3) Fermentation: turn the pile when the temperature rises to 50°C, and keep the moisture content at 50wt%; when the temperature reaches 50-70°C again and every time the monitoring reaches 50-70°C, add 8% of the total mass of the basic material % lignite, while adding water still ensures that the water content is 45-55wt%. It takes about 22 days from the establishment of the heap to the completion of decomposing. The organic matter of the obtained stable carbon source organic fertilizer is about 25...

Abstract

The invention discloses a preparation method of a stable carbon source organic fertilizer. The stable carbon source organic fertilizer is prepared by utilizing charcoal and/or brown coal as a stable carbon source, and mixing the stable carbon source with the mixed composted material of cow dung and mushroom residue and seaweed residue, wherein the cow dung, the mushroom residue and the seaweed residue are fermented in a volume ratio of 2 to 1 to (0-0.05) to form a basic material, and the charcoal and/or the brown coal which are equal to 5%-10% of mass of the basic material are added. The preparation method comprises the following steps: (1) preparing the basic material: grinding the cow dung, the mushroom residue and the seaweed residue, and uniformly mixing, so as to obtain the basic material; (2) blending and uniformly mixing: adding a composting agent and water into the basic material, blending, and uniformly mixing to obtain a compound fermenting material; and (3) fermenting: stacking the fermenting material, carrying out high temperature composting, and adding the charcoal and/or the brown coal as the carbon source, so as to obtain the stable carbon source organic fertilizer after the fermentation. By virtue of the preparation method, the total content of organic carbon is increased; meanwhile, by adding the seaweed residue rich in soluble carbon, organic carbon can be easily absorbed by crops; and the stable carbon source organic fertilizer with strong practicability and high quality can be obtained.

Description

technical field [0001] The invention relates to a preparation method of an organic fertilizer, in particular to a preparation method of a stable carbon source organic fertilizer. Background technique [0002] The production of organic fertilizer needs to adjust the appropriate carbon-nitrogen ratio to ensure microbial decomposition. However, the composting process is a process that releases a large amount of carbon dioxide and other gases. The organic carbon content of the finished organic fertilizer will be greatly reduced compared with the initial material. [0003] As the first of the 17 essential nutrient elements, carbon ranks first in the composition percentage of plant elements, and far exceeds the sum of NPK. "Carbon fertilizer" has received more and more attention. Organic carbon nutrition also mainly refers to organic fertilizer carbon compounds with high water solubility and easy absorption. Commonly used are sugar, alcohol, acid and so on. Contents of the inven...
