Embodiment 1

[0026] In this example, the raw materials for the preparation of organic matter all come from branches of urban maintenance in Binhai New Area, Tianjin.

[0027] In the present embodiment, the preparation method of organic matter is:

[0028] (1) crush urban fallen leaves into powder as the main ingredient, and spray water to make the powder moist;

[0029] (2) Add the following amount of bacterial agent 1 per 10,000 parts of dry leaf powder: 20-30 parts, 20-30 parts of soft rot fungi, 20-30 parts of brown rot fungi, 20-30 parts of white rot fungi, and 20 parts of lactic acid bacteria - 25 parts, stacked and fermented indoors for 5-9 days; heat the fermented product above 90 degrees Celsius for 30-60 minutes, or irradiate it under ultraviolet light for 1-3 hours;

[0030] (3) Add bacterial agents 2 per 10,000 parts of dry leaf powder at room temperature: 10-25 parts of heat-resistant bacillus group, 10-20 parts of lactic acid bacteria group, 8-15 parts of bifidobacteria group...

Embodiment 2

[0034] In this example, the fermented product obtained in Example 1 is dehydrated. First, the fermented product is absorbed by a water-absorbing agent, and then the absorbed water-absorbing agent and the fermented product are separated by a microfiltration membrane. It should be understood that the dehydration treatment is only to achieve the purpose of dehydrating the fermented product to obtain organic fertilizer, and the present invention is not limited to the dehydration method.

[0035] In the organic fertilizer provided by the invention, the organic matter comes from urban fallen leaves, and the organic matter accounts for 88.66%.

[0036] The following is an analysis of the composition of the organic fertilizer provided by the present invention. In this embodiment, the composition of the organic fertilizer obtained by the method for preparing the organic fertilizer of the present invention is analyzed through experimental testing. Specifically, the experimental detectio...

Embodiment 3

[0040] The organic fertilizer of the present invention of embodiment 1 is used for cultivating Pennisetum and Stipa grandis in Tianjin Binhai New Area. Tianjin Binhai New Area is located in the Bohai Bay, especially in Tanggu and Dagang, where the soil salinization is serious, with high salt content, lack of fertility and low organic matter content.

[0041] Pennisetum cultivation method, comprises the following steps:

[0042] 1) Cultivation site selection: choose urban broad-leaved forests in saline-alkali areas, with an altitude of 2-5 meters; choose Pennisetum seeds, with a germination rate greater than or equal to 85%; apply 300 kg / mu of landscaping organic fertilizer or urban deciduous fermentation before sowing Organic fertilizer 300 kg / mu, avoid trees and dig the soil 50cm deep, and then prepare the land to make the land ready for sowing;

[0043] 2) The sowing time of Pennisetum is in early spring and early March, and the site preparation should be fine. After sowing, ...

Abstract

The invention discloses a microbial inoculum composition for fermenting an urban fallen leaf and a fermentation process thereof. The microbial inoculum composition is prepared from microbial inocula 1: actinomycetes, soft-rot fungi, brown-rot fungi, white-rot fungi and growth inhibition lactobacilli for inhibiting butylic acid bacteria and putrefying bacteria; microbial inocula 2: a thermophilic bacillus group, a lactobacillus group, a bifidobacterium group, a photosynthetic bacterium group, a saccharomyces group and an actinomycetes group; microbial inocula 3: saccharomyces and photosynthetic bacteria. The fermentation process comprises the following steps of smashing the urban fallen leaf into powder, and spraying water to damp the powder; adding the microbial inocula 1, and carrying out heap fermentation for several days indoors; adding the microbial inocula 2, preventing aerobiotic humic acid bacteria and the butylic acid bacteria from growing, and continuously fermenting for several ten days; adding the microbial inocula 3 and fermenting for several days. By using the microbial inoculum composition and the fermentation process thereof which are provided by the invention, the treatment problem of the urban fallen leaf is solved; the pollution problem is solved; meanwhile, a waste thing is changed into a valuable thing; a fertilizer made by the method is high in nitrogen, phosphorus and potassium contents, and is excellent organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of biological fermentation engineering, in particular to a bacterial agent combination for urban fallen leaf fermentation and a fermentation process thereof. Background technique [0002] With the rapid development of urban greening, urban green spaces are rapidly expanding, and urban leaves are produced in large numbers, especially in autumn and winter in northern cities. The traditional concept often believes that the fallen leaves of trees affect health and landscape, so a lot of manpower and funds are spent every year to clean and burn them, which puts a lot of pressure on municipal management and causes great pollution to the environment. [0003] At present, there are mainly three methods for dealing with fallen leaves of trees in major landscaping areas: sanitary landfill, incineration and traditional method of composting, but these methods have certain limitations: 1. The landfill operation is simple...
