Problems solved by technology

Among them, in the patent report on making fertilizers, there are still the following problems to be further explored: (1) Adding chemical decomposing agents, although to a certain extent alleviated the problem that garden plant wastes are difficult to degrade, but the decomposing time is still long ( 24-34 days), and the decomposing effect of woody plants with a high degree of lignification is not ideal; (2) The fermentation temperature i...

Embodiment approach 1

[0029] Embodiment one: the method of utilizing garden plant waste to prepare organic fertilizer in this embodiment is:

[0030] (1) Coarsely crush woody plant wastes to 3-4 cm, and herbaceous plant wastes to 0.1-1 cm; woody plant wastes are tree and shrub residues, and herbaceous wastes are leaves or herbaceous plant residues.

[0031] (2) Dry the crushed woody plant waste naturally for 15 days, carbonize, and crush to 100-150 meshes to obtain block carbonized materials; the heating rate of the carbonization process is 5°C / min, and the carbonization temperature is 500°C. From the beginning of heating to the end time is 1 hour;

[0032] (3) Mix the crushed herbaceous plant waste with high-temperature microbial strains, then add clear water to keep its water content at 55%, and add 2% of its mass urea, stir and mix well, and make a pile. The size is 1.5m in width and 1.5m in height, and the temperature of the pile is maintained at 60°C. Poke a small hole with a diameter of 2cm ...

Embodiment approach 2

[0034]Embodiment two: the method of utilizing garden plant waste to prepare organic fertilizer in this embodiment is:

[0035] (1) Coarsely crush woody plant wastes to 5 cm, and herbaceous plant wastes to 0.1 cm; woody plant wastes are tree and shrub residual branches, and herbaceous plant wastes are leaves or herbaceous plant residues.

[0036] (2) Dry the crushed woody plant waste naturally for 20 days, carbonize, and crush to 100-200 meshes to obtain block carbonized materials; the heating rate of the carbonization process is 10°C / min, and the carbonization temperature is 3000°C. From the beginning of heating to the end of the time is 3 hours;

[0037] (3) Mix the crushed herbaceous plant waste with high-temperature microbial strains, then add water to keep its water content at 65%, and add 1% of its mass urea, stir and mix well, and make a pile. The size is 2m in width and 1-1.5m in height, and the temperature of the pile is maintained at 70°C. Poke a small hole with a di...

Embodiment approach 3

[0039] Embodiment three: the method of utilizing garden plant waste to prepare organic fertilizer in this embodiment is:

[0040] (1) Coarsely crush woody plant wastes to 4 cm, and herbaceous plant wastes to 0.9 cm; woody plant wastes are tree and shrub residues, and herbaceous wastes are leaves or herbaceous plant residues.

[0041] (2) Dry the pulverized woody plant waste naturally for 16 days, carbonize, and pulverize to 120 meshes to obtain block carbonized materials; the heating rate of the carbonization process is 8°C / min, and the carbonization temperature is 400°C. Warming up to end time is 2 hours;

[0042] (3) Mix the crushed herbaceous plant waste with high-temperature microbial strains, then add clear water to keep its water content at 60%, and add urea with a mass of 1.6%, stir and mix well, and make a pile. The size is 1.8m wide and 1.3m high, and the temperature of the pile is maintained at 65°C. Poke a small hole with a diameter of 1.6cm and a depth of 1.6cm on...

Abstract

The invention relates to a method for preparing a biological organic fertilizer by utilizing garden plant waste, and belongs to the field of forestry biological environment. With the garden plant waste as main raw material, wood waste having higher lignification degree is carbonized, and a powdery carbonized material is obtained; grass waste having lower lignification degree is subjected to high-temperature microbial fermentation decomposition, and a decomposed material is obtained; and then the powdery carbonized material and the decomposed material are mixed in proper proportion, the novel biological organic fertilizer enriched with biochar is prepared, and a new way is provided for resource utilization of the garden plant waste.

Description

technical field [0001] The patent of the invention relates to a method for preparing bio-organic fertilizer by utilizing garden plant waste, which belongs to the field of forestry bio-environment. Background technique [0002] Garden plant waste mainly refers to the plant residues produced by the natural fall of garden plants or artificial pruning, mainly including leaves, grass clippings, tree and shrub pruning, etc., and its main component is wood fiber. With the continuous increase of urban green coverage, the amount of garden plant waste is increasing. If landfill, incineration or arbitrary disposal is used, it will not only affect the appearance of the city, but also may cause environmental pollution. [0003] At present, the United States, Australia and other countries have accumulated a lot in the collection and utilization of garden plant waste. Urban greening has gone out of the traditional era of using natural soil, and replaced it with the use of urban and rural w...
