Embodiment 1

[0034] An organic fertilizer is prepared by utilizing cow dung and straw, and the preparation method comprises the following steps:

[0035] S1: Crush corn stalks and fruit and vegetable stalks into small pieces no longer than 5cm in length, then uniformly mix cow dung, fruit and vegetable stalks and corn stalks at a mass ratio of 2:1:1, and add dry and wet materials to reduce the content of the mixture. Adjust the water volume to about 60% to obtain a compost matrix;

[0036] S2: Stack the compost substrate layer by layer to form a heap body. The heap body is stacked in a total of 5 layers; each layer is about 25cm thick, and each layer of compost substrate is sprayed with a decomposing agent solution. The decomposing agent solution includes the following components in mass percentage: Bacillus subtilis Bacillus 2wt%, Aspergillus oryzae 1wt%, saccharomyces 1wt%, and the balance is water; and a layer of decomposed fertilizer with a thickness of about 2cm is laid between every ...

Embodiment 2

[0041] An organic fertilizer is prepared by utilizing cow dung and straw, and the preparation method comprises the following steps:

[0042] S1: Crush mushroom dregs and fruit and vegetable stalks into small pieces no longer than 5cm in length, then uniformly mix cow dung, fruit and vegetable stalks, and mushroom dregs at a mass ratio of 1:4:1, and add dry and wet materials to the content of the mixture. Adjust the water volume to about 65% to obtain a compost matrix;

[0043]S2: Stack the compost substrate layer by layer to form a heap. The heap body is stacked in 4 layers; each layer is about 25cm thick, and each layer of compost substrate is sprayed with a decomposing agent solution. The decomposing agent solution includes the following components in mass percentage: Bacillus subtilis Bacillus 1wt%, Aspergillus oryzae 1.5wt%, saccharomyces 0.5wt%, and the balance is water; and lay a layer of decomposed manure with a thickness of about 5cm between every two layers of compost...

Embodiment 3

[0048] An organic fertilizer is prepared by utilizing cow dung and straw, and the preparation method comprises the following steps:

[0049] S1: Grind the biochar and fruit and vegetable straws into small pieces with a length of no more than 5cm, then mix the cow dung, fruit and vegetable straws and biochar evenly at a mass ratio of 3:2:1, and mix the mixture by adding dry and wet materials The water content of the fertilizer is adjusted to about 55% to obtain a compost matrix;

[0050] S2: Stack the compost substrate layer by layer to form a heap body. The heap body is stacked in a total of 6 layers; each layer is about 20cm thick, and each layer of compost substrate is sprayed with a decomposing agent solution. The decomposing agent solution includes the following components in mass percentage: Bacillus subtilis Bacillus 3wt%, Aspergillus oryzae 0.5wt%, saccharomyces 1.5wt%, and the balance is water; and lay a layer of decomposed fertilizer with a thickness of about 2cm betw...

Abstract

The invention discloses an organic fertilizer prepared from cow dung and straws and a preparation method thereof. The preparation method comprises the following steps: firstly, uniformly mixing cow dung, fruit and vegetable straws and high-carbon auxiliary materials; stacking a mixture obtained in the previous step layer by layer to form a piled body, and spraying a decomposition agent and fillingthe piled body with a decomposition fertilizer in the process of stacking; and introducing hot air into the piled body, covering the surface of the piled body with a thin film, turning over the piledbody for the first time after a period of time, adding a nitrogen fixing agent in the process, covering the piled body with the thin film for continuous composting, uncovering the thin film after a period of time, and performing free composting to obtain the organic fertilizer. By adopting the method disclosed by the invention, harmless treatment of vegetable waste can be realized, the vegetablewaste can be recycled as a fertilizer, and environmental pollution can be effectively avoided; and the organic fertilizer prepared by adopting the method disclosed by the invention is easily absorbedby crops and plays a positive role in increasing the yield of the crops.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, and in particular relates to an organic fertilizer prepared from cow dung and straw and a preparation method thereof. Background technique [0002] With the improvement of the intensification of planting and breeding in my country and the continuous expansion of production scale, the waste produced has caused serious risks to environmental pollution. In recent years, with the rapid development of animal husbandry and planting, agricultural wastes such as animal manure and fruit and vegetable residues have become important agricultural wastes. If they are not treated and discharged directly into the environment, they will cause water pollution, spread of pathogenic bacteria, etc. problems and pose a serious threat to human and livestock health. Therefore, how to rationally utilize livestock and poultry manure, crop stalks, especially a large amount of vegetable waste genera...
