Description

Technical Field

[0001] The invention relates to the technical field of biological organic fertilizers, and in particular to a method for preparing greenhouse vegetable organic fertilizer from erythromycin residues. Background Art

[0002] The amount of fertilizer applied in my country has increased year by year, especially the amount of nitrogen fertilizer applied, which has reached 300kg / hm2 of pure nitrogen or even higher. In addition to providing normal growth of crops, these chemical elements applied to the soil also lose nitrate nitrogen to the atmosphere through denitrification or are lost in the water through rainwater erosion. Phosphorus is deposited in the soil or lost in the water, leading to eutrophication of water bodies. A small part of it exists in crops as substances harmful to human health, such as nitrates. In addition, since the production of fertilizers consumes a lot of energy, it causes economic losses. At the same time, it emits a large amount of harmful gases such as CO2 and SO2, which seriously affects air quality and causes global warming. In addition, the application of inferior fertilizers can easily lead to heavy metal pollution in soil and agricultural products, which directly affects the survival of humans, animals and plants.

[0003] Bio-organic fertilizers largely avoid the adverse factors brought by chemical fertilizers, thus contributing to improving the environment and implementing the sustainable development strategy of agriculture. On the other hand, the application of bio-organic fertilizers also solves the pollution of the environment caused by the increasing amount of organic solid wastes. As long as these organic solid wastes are treated with appropriate methods and beneficial microorganisms are added, high-quality bio-organic fertilizers can be produced, so that natural resources can be well recycled. In some recent studies on bio-organic fertilizers, it was found that the application of bio-organic fertilizers does not harm the environment, can reduce farmland environmental pollution, and continuous application for many years can create a good soil physical and chemical properties and ecological conditions for crop production. The use of bio-organic fertilizers can alleviate the harm caused to the farmland ecological environment and human health by the long-term use of chemical agents such as pesticides and fertilizers.

[0004] Bio-organic fertilizer refers to a type of fertilizer that combines specific functional microorganisms with organic materials that are mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. Bio-organic fertilizers contain a large number of beneficial microorganisms that can promote the biological transformation process in the soil, produce rich organic matter, and help continuously improve soil fertility.

[0005] The erythromycin fermentation liquid is filtered through a ceramic membrane for solid-liquid separation to obtain a concentrated liquid containing a small amount of erythromycin, which is then spray-dried and inactivated at high temperature to obtain erythromycin residue. The residue is rich in organic nutrients such as protein and amino acids, as well as important inorganic nutrients such as nitrogen, phosphorus and potassium. Its use as a fertilizer will achieve a better yield-increasing effect than livestock and poultry manure and straw organic fertilizers.

[0006] Erythromycin residue is generally defined as hazardous waste. Erythromycin raw material production enterprises need to incinerate or bury the erythromycin residue, which increases huge costs and seriously affects the economic benefits of production enterprises. The process of composting erythromycin residue to make organic fertilizer can effectively degrade erythromycin. The harmless treatment and resource utilization of erythromycin residue has become the development direction of erythromycin residue treatment.

[0007] The invention patent "An organic fertilizer prepared from erythromycin residue and its preparation method 202110939603.8", the invention patent "An organic fertilizer pile fermentation method based on residue 202211208564.5" uses more than two strains of bacteria for composting fermentation, which is easy to produce antagonistic effects. Moreover, the growth and metabolism of different bacteria have different requirements for temperature, pH and other environmental factors. A fermentation condition control is carried out to affect the growth metabolism of the strains and the results of biological fermentation conversion.

[0008] The fermentation cycle of these two invention patents is relatively long, reaching 8 to 14 days, and the processing efficiency is relatively low, requiring the addition of more facilities. In addition, during the general composting fermentation process, a strong odor is often emitted, which has an adverse impact on the production site environment and the surrounding environment of the factory area.

[0009] How to promote the decomposition and transformation of organic matter in the process of organic fertilizer preparation, produce high-efficiency organic nutrients, improve vegetable quality and increase vegetable yield, and at the same time, make the production process environmentally friendly, reduce the odor of compost fermentation, improve the production environment, and not cause environmental pollution around the factory has become a problem that needs to be solved urgently. Summary of the invention

[0010] The present invention provides an organic fertilizer specially made for greenhouse vegetables by utilizing erythromycin residue and a preparation method thereof. Through secondary fermentation of the erythromycin residue, the problem that existing biological organic fertilizers cannot prevent and control pests on the basis of satisfying the requirements of supplementing nutrition or improving soil properties is solved, the fertilizer efficiency is improved while soil-borne diseases are suppressed, and the odor in the organic fertilizer production process is effectively controlled.
