Problems solved by technology

On the one hand, this method will inevitably cause waste of resources because the cow dung must be dried in advance, and a large amount of malodorous gas will be emitted during the drying process, which will pollute the environment; A large amount of water in cow dung is removed by drying in the early stage, and water needs to be added artificially in the subsequent fermentation process. This process obviously has certain defects
Another treatment method is to mix fresh cow dung with crop straw, etc., and then ferment. However, this method is likely to cause the straw to be incompletely decomposed. Agricultural production poses risks

Embodiment 1

[0033] Weigh 500 kg of fresh cow dung, add 15 kg of potassium polyacrylate and 15 kg of polyacrylamide to it, mix well, then let it stand for 24 hours, and measure the water content of cow dung to be about 65%. After that, add 0.5 kg of Clostridium powder, 1.5 kg of Bacillus subtilis powder, 1 kg of saccharomyces powder and 0.5 kg of lactic acid bacteria powder in the above-mentioned cow manure, and mix well. Then, the obtained mixed material was placed in an anaerobic fermentation tank for anaerobic fermentation, the fermentation temperature was 60° C., and the fermentation time was 25 days. After the fermentation is completed, the fermented material is taken out, left to air at normal temperature, then pulverized and packaged to obtain the organic fertilizer of the present invention.

Embodiment 2

[0035] Weigh 500 kg of fresh cow dung, add 35 kg of potassium polyacrylate and 15 kg of starch-acrylic acid graft copolymer to it, mix well, and then let it stand for 12 hours. The water content of cow dung is determined to be about 60%. After that, add 0.5 kg of Bacillus colloidus, 0.2 kg of Bacillus subtilis and 0.3 kg of lactic acid bacteria powder to the above-mentioned cow dung, and mix well. Then, the obtained mixed material was placed in an anaerobic fermentation tank for anaerobic fermentation, the fermentation temperature was 50° C., and the fermentation time was 30 days. After the fermentation is completed, the fermented material is taken out, left to air at normal temperature, then pulverized and packaged to obtain the organic fertilizer of the present invention.

Embodiment 3

[0037] Weigh 500 kg of fresh cow dung, add 5 kg of sodium polyacrylate and 10 kg of polyacrylamide to it, mix well, then let it stand for 20 hours, and measure the water content of cow dung to be about 68%. Afterwards, 2 kg of Bacillus megaterium, 2 kg of Bacillus subtilis, and 2 kg of Rhodopseudomonas palustris were added to the above-mentioned cow dung, and mixed evenly. Then, the obtained mixed material was placed in an anaerobic fermentation tank for anaerobic fermentation, the fermentation temperature was 55° C., and the fermentation time was 22 days. After the fermentation is completed, the fermented material is taken out, left to air at normal temperature, then pulverized and packaged to obtain the organic fertilizer of the present invention.

Abstract

The invention relates to a method for preparing an organic fertilizer by fermenting cattle manure. A water-absorbing resin is added into fresh cattle manure; and the water-absorbing action of the water-absorbing resin is utilized to absorb water in the fresh cattle manure, thereby adjusting the water content of the cattle manure to the water content required by fermentation. Thus, the early drying process of the fresh cattle manure can be saved; and after the fertilizer is applied to the field, the water-absorbing resin can perform the functions of water retention and soil moisture preservation, and thus, is beneficial to crop growth, thereby enhancing the crop yield. Besides, by adopting the specific fermentation microbial inoculant, the cattle manure can be fermented and rotten thoroughly, thereby being beneficial to nutrient absorption of the crops.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a method for preparing organic fertilizers by fermenting cow dung. Background technique [0002] With the continuous development of my country's large-scale livestock and poultry breeding industry, the production of livestock and poultry manure is also increasing. If a large amount of livestock and poultry manure is not treated in a harmless manner after production, it will not only produce malodorous gas, but also cause serious environmental pollution. Pollution can also breed mosquitoes and lead to the widespread spread of pathogenic bacteria, threatening human health. [0003] Due to the high water content of fresh cow dung, it is usually not possible to process it directly. At present, there are two main processing methods: one processing method is to dry the cow dung or air-dry it naturally, then crush it, and then ferment it. On the one hand, this method will inevitably cause wa...
