Embodiment 1
[0052] Embodiment 1, the present invention utilizes the method for composting of penicillin fungus slag to prepare organic fertilizer
[0053] Specifically include the following steps:
[0054] Step a: The penicillin fermentation filter residue obtained after plate and frame filtration is subjected to a disc drying process at 105° C. for a residence time of 1.0 h, and the penicillin content is detected to be lower than the detection limit (0.1 mg / L) by high-performance liquid chromatography to obtain penicillin bacteria For unqualified materials, the disc drying process is carried out again until the penicillin content in the penicillin slag is lower than the detection limit (0.1mg / L);
[0055] Step b: Take penicillin scum, cow dung, and straw, mix according to 40 parts of penicillin slag (calculated by dry weight), 30 parts of cow dung (calculated by dry weight), and 30 parts of straw (calculated by dry weight), get mixed materials;
[0056] Step c: Add 3g of compost fermen...
Embodiment 2
[0068] Embodiment 2, the present invention utilizes the method for composting penicillin slag to prepare organic fertilizer
[0069] Specifically include the following steps:
[0070] Step a: The penicillin fermentation filter residue after plate and frame filtration is subjected to a disc drying process at 105°C with a residence time of 1.0h, and the penicillin content is detected to be lower than the detection limit (0.1mg / L) by high-performance liquid chromatography to obtain penicillin scum For unqualified materials, the disc drying process is carried out again until the penicillin content in the penicillin slag is lower than the detection limit (0.1mg / L);
[0071] Step b: Take penicillin scum, cow dung, and straw, mix according to 70 parts of penicillin slag (calculated by dry weight), 15 parts of cow dung (calculated by dry weight), and 15 parts of straw (calculated by dry weight), get mixed materials;
[0072] Step c: Add 3g of compost fermentation bacteria per kg of ...

Abstract
The invention provides a method for preparing an organic fertilizer by using penicillin mushroom dreg compost, and relates to the technical field of organic fertilizers. The organic fertilizer is prepared from the following raw materials in parts by weight: 30-70 parts of penicillin mushroom dregs, 15-35 parts of cow dung, 15-35 parts of straws and 0.1-0.3 part of a compost fermentation inoculant, wherein the content of penicillin in the penicillin mushroom dregs is less than or equal to 0.1 mg/L. The organic fertilizer prepared by the invention is high in content of organic matter, balanced in content of nutrient substances such as nitrogen, phosphorus and potassium and high in total amount, particularly, the content of nitrogen element is remarkably increased, sufficient nutrition can be provided for plants, and good growth of the plants can be promoted under the condition of low fertilizing amount. Meanwhile, the organic fertilizer is subjected to innocent treatment, penicillin is removed, generation and propagation risks of drug-resistant genes can be avoided, and the organic fertilizer is safe to use. The organic fertilizer prepared by the method provided by the invention overcomes the defect of drug-resistant gene transmission risk in preparation of the organic fertilizer from antibiotic mushroom dreg compost in the prior art, and has good application prospects.
Description
technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a method for preparing organic fertilizers by composting penicillin fungus residues. Background technique [0002] As a great invention in the 19th century, chemical fertilizers were widely used in the 20th century, making extremely important contributions to the global agricultural economy and food sources for all mankind. However, with the abuse of chemical fertilizers, the physical and chemical properties of the soil, especially the pH, have undergone malignant changes, the soil aggregate structure has been destroyed, and the water retention capacity has decreased, which has become a global agricultural problem. At the same time, heavy metals such as chromium, cadmium and nickel have been continuously accumulated with fertilizer application, which has caused the heavy metal content of crops in some areas to exceed the standard, which has a negative impact on the qu...
