Example Embodiment

[0033] Example 1

[0034] An organic fertilizer, which is prepared from cow dung and straw, and the preparation method includes the following steps:

[0035] S1: The corn stalks and fruit and vegetable stalks are crushed into small segments of no more than 5 cm in length, and then the cow dung, fruit and vegetable stalks and corn stalks are uniformly mixed in a mass ratio of 2:1:1, and the content of the mixture is added by adding dry and wet materials. Adjust the water volume to about 60% to obtain a compost substrate;

[0036] S2: Stack the compost substrate layer by layer to form a pile, stacking a total of 5 layers; each layer is about 25cm thick, and spray a composting agent solution for each layer of composting matrix. The composting agent solution includes the following mass percentage components: subtilis spores Bacillus 2wt%, Aspergillus oryzae 1wt%, yeast 1wt%, the balance is water; and a layer of decomposed fertilizer with a thickness of about 2cm is laid between every tw...

[0040] Example 2

[0041] An organic fertilizer, which is prepared from cow dung and straw, and the preparation method includes the following steps:

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

[0043] S2: Stack the compost substrate layer by layer to form a pile, stacking a total of 4 layers; each layer has a thickness of about 25cm, and spray a composting agent solution for each layer of composting matrix. The composting agent solution includes the following mass percentage components: subtilis spores Bacillus 1wt%, Aspergillus oryzae 1.5wt%, Yeast 0.5wt%, the balance is water; and a layer of decomposed fertilizer with a thickness of about 5cm is laid between every two...

Example Embodiment

[0047] Example 3

[0048] An organic fertilizer, which is prepared from cow dung and straw, and the preparation method includes the following steps:

[0049] S1: Crush the biomass charcoal and fruit and vegetable stalks into small segments of no more than 5cm in length, and then mix the cow dung, fruit and vegetable stalks and biomass charcoal at a mass ratio of 3:2:1, and mix the mixture by adding dry and wet materials Adjust the moisture content of the water to about 55% to obtain a compost substrate;

[0050] S2: Stack the compost substrate layer by layer to form a pile, stacking a total of 6 layers; each layer has a thickness of about 20cm, and each layer of the compost substrate is sprayed with a composting agent solution. The composting agent solution includes the following mass percentage components: subtilis spores Bacillus 3wt%, Aspergillus oryzae 0.5wt%, yeast 1.5wt%, the balance is water; and a layer of decomposed manure with a thickness of about 2cm is laid between every...

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...
