Problems solved by technology

[0005] The above reports and patents show that urban litter can be converted into organic fertilizers under the action of microorganisms, but some auxiliary materials such as table garbage, feces, sludge, peat and so on are added in the process of decomposing and fermenting, which is not convenient for large-scale production. Collection and transportation; some auxiliary materials are added more, which makes the product cost higher; some fermentation strains are natural, or two kinds of bacteria agents, resulting in a longer fermentation cycle

Embodiment 1

[0036] A kind of method utilizing urban litter waste to produce organic fertilizer, its steps are as follows:

[0037] 1. The concentrated 1000 kilograms of camphor tree litter and leaves and other greening wastes are processed by a branch cutter and a pulverizer into a particle size of 3-5 cm, and the moisture content is determined to be 20%;

[0038] 2. 0.8 kilograms of composite microbial bacterial agents mixed in a ratio of 2:1:1:2 (w / w) by Aspergillus niger, Saccharomyces cerevisiae, Bacillus subtilis and Trichoderma reesei are compounded with 8 kilograms of bran, well mixed.

[0039] Add 4.0 kg of urea and 4.8 kg of potassium dihydrogen phosphate to 1000 kg of materials to adjust the C / N ratio to 20:1, and the C / P ratio to 75:1 to mix with the compound microbial agent.

[0040] 3. Adjust the moisture content of the litter material to 60%.

[0041] 4. Building piles of materials. After mixing well, build a heap with a height of 1.5 meters and a conical shape.

[0042]...

Embodiment 2

[0046] A method for producing organic fertilizer by utilizing urban litter waste is applied in the preparation of organic fertilizer, and the process is as follows:

[0047] Utilize the fermented and decomposed organic fertilizer of embodiment 1 to be used for the plantation of greening lawn

[0048] 0.5 tons of the above-mentioned decomposed organic fertilizers are evenly applied to the soil of one mu of land for planting Paradise Grass lawn, plowed, leveled, sowed grass seeds, watered and managed. At the same time, the lawn planting control without organic fertilizer was done.

[0049] Result: the lawn that used the organic fertilizer that the dead branches and fallen leaves are decomposed is obviously better than the control in terms of seed germination, grass greenness, and growth speed (see Table 1), which is shown in: increased seed germination rate, high chlorophyll content, growth The sky height difference is about 3 cm.

[0050] The organic fertilizer of table 1 the...

Embodiment 3

[0053] A kind of method utilizing urban litter waste to produce organic fertilizer, its steps are as follows:

[0054] What is different from Example 1 is: the composite microbial inoculum is that 1.6 kilograms of compound microbial inoculums are made of Aspergillus niger, Saccharomyces cerevisiae, Bacillus subtilis and Trichoderma reesei with 24 kilograms of chaff powder or 24 kilograms of peanut shell powder. Compounding and mixing; the fermentation period is 20 days, and the remaining conditions are the same as in Example 1.

[0055] After the fermentation, the organic matter content in the product was 53.5%, nitrogen 1.9%, phosphorus pentoxide 1.6%, potassium oxide 1.3%, moisture 35% and pH 7.3.

Abstract

The invention provides a method for producing an organic fertilizer from municipal dry branch / fallen leaf waste and application thereof. The method comprises the following steps: collecting branches, fallen leaves and other municipal greening wastes, and mixing Aspergillus niger, Saccharomyces cerevisiae, Bacillus subtilis and Trichoderma reesei to obtain a composite microbial inoculant; adding bran coat, chaff powder or peanut hull meal, the composite microbial inoculant, urea and potassium dihydrogen phosphate, thoroughly mixing, piling into a 1.5-2m-high cone, and controlling the water content at 60-70%; carrying out hide lifting on the pile in the composting process, and fermenting for 20-30 days; and carrying out aerobic and anaerobic fermentation on the dry branch / fallen leaf waste by using the microbial inoculant to obtain the organic fertilizer. The preparation technique is simple; and the prepared organic fertilizer can improve the soil and reduce the environmental pollution caused by the waste.

Description

technical field [0001] The invention relates to a method for producing organic fertilizer by using urban litter and fallen leaves. After the litter and fallen leaves are stacked and fermented, the method can be used as fertilizer to restore to green land and under forests, and can also be used as a substrate for flower and tree cultivation and a soil improver. The utility model relates to a three-dimensional space greening medium, which belongs to the field of biotechnology. Background technique [0002] Greening waste, including urban landscaping and suburban forestry tending, tree branches, fallen leaves, grass clippings, flower rot and other trimmings produced during fruit tree pruning. With the vigorous development of urban greening in our country, the total amount of greening waste produced every year is also increasing sharply. At present, the main ways to deal with these green wastes are incineration and landfill. Incineration will cause serious air pollution and is...
