Embodiment 1

[0021] Embodiment 1: a kind of fermenting method of semi-decomposed material, specifically comprises steps:

[0022] (1) Crush the frozen branches of Ficus xiaoye into small sections with a length of 3 cm and a thickness of 1 cm;

[0023] (2) Evenly mix crushed materials with microbial strains, carry out aerobic fermentation for 15 days, and obtain semi-decomposed materials.

[0024] Specifically, in step (1), the pulverization operation is mainly completed by a pulverizer.

[0025] Further, in step (2), add clear water to make the water content of the pulverized material 55%, then add microbial strains and stir evenly. The room temperature of the stirring operation is 16°C to ensure that the added microbial strains can play their role. active.

[0026] Specifically, in step (2), the pulverized material is also mixed with urea, so that the amount of urea added is 0.1% of the mass of the pulverized material, so as to speed up the fermentation process and increase the nitrogen...

Embodiment 2

[0034] Embodiment 2: a kind of fermenting method of semi-decomposed material, specifically comprises steps:

[0035] (1) Crush the frozen branches of Tianzhugui into small pieces with a length of 6cm and a thickness of 2cm;

[0036] (2) Mix the pulverized material with microbial strains and carry out aerobic fermentation for 20 days to obtain semi-decomposed materials.

[0037] Specifically, in step (1), the pulverization operation is mainly completed by a pulverizer.

[0038] Further, in step (2), add clear water to make the water content of the pulverized material 60%, then add microbial strains and stir evenly. The room temperature of the stirring operation is 26°C to ensure that the added microbial strains can play their role. active.

[0039] Specifically, in step (2), the pulverized material is also mixed with urea, so that the amount of urea added is 0.5% of the mass of the pulverized material, thereby speeding up the fermentation process and increasing the nitrogen c...

Embodiment 3

[0047] Embodiment 3: a kind of fermentation method of semi-decomposed material, specifically comprises steps:

[0048] (1) Crush the frozen jacaranda branches into small pieces with a length of 10 cm and a thickness of 3 cm;

[0049] (2) Mix the pulverized material with microbial strains and carry out aerobic fermentation for 30 days to obtain semi-decomposed materials.

[0050] Specifically, in step (1), the pulverization operation is mainly completed by a pulverizer.

[0051] Further, in step (2), add clear water to make the water content of the pulverized material 65%, then add microbial strains and stir evenly. The room temperature of the stirring operation is 30°C to ensure that the added microbial strains can exert their active.

[0052] Specifically, in step (2), the pulverized material is also mixed with urea, so that the amount of urea added is 1% of the mass of the pulverized material, thereby speeding up the fermentation process and increasing the nitrogen content...

Abstract

The invention relates to a fermentation method and an application of a semi-composted material and belongs to the field of human settlement environment, urban forestry and the like. The method specifically comprises the steps as follows: S1, residual branches obtained during tree trimming are crushed into sections which are 3-10 cm long and 1-3 cm thick; S2, the crushed material obtained in S1 isuniformly mixed with microbial strains, the mixture is subjected to aerobic fermentation for 15-30 d, and the semi-composted material is obtained. The semi-composted material covers the surface of immature soil under trees, the condition that dust on the surface of immature soil under trees is blown into the air by wind to become a carrier of sulfur dioxide and other pollutants can be effectivelyprevented, PM2.5, PM10 and other particulates in the air can be effectively adsorbed, particulate matter can be washed out and penetrates through the ground after raining and cannot be blown into theair by wind again, and the better anti-haze effect is realized.

Description

technical field [0001] The invention relates to a fermentation method and application of semi-decomposed materials, belonging to the fields of human settlements, urban forestry and the like. Background technique [0002] Smog is a general expression of the excessive content of various suspended particles in the atmosphere. It is specifically manifested as an aerosol system composed of dust, sulfuric acid, nitric acid, organic hydrocarbons and other particles in the air causing visual impairment. Among them, sulfur dioxide, nitrogen oxides, and inhalable particulate matter in the air are the main components of smog. The former two are gaseous pollutants, and particulate matter is the culprit that aggravates the pollution of haze weather. They combine with fog to make the sky instantly gray, forming smog to pollute the atmosphere. The English abbreviation of particulate matter is PM, especially PM2.5 (particulate matter with an aerodynamic equivalent diameter less than or equ...
