Description

Technical Field

[0001] This invention relates to the field of resource utilization of livestock breeding waste and production of ecological fertilizer, specifically a method for producing high-efficiency ecological fertilizer from livestock and poultry breeding waste. Background Technology

[0002] Livestock and poultry breeding waste, primarily composed of livestock and poultry manure, poses a serious threat to the ecological environment if its organic waste is not treated promptly and scientifically. Firstly, it causes eutrophication of water bodies, with nitrogen and phosphorus from the manure entering rivers and lakes via runoff. Secondly, it pollutes soil and groundwater, with high concentrations of salt, heavy metals, and pathogenic microorganisms seeping into the ground. Thirdly, it produces foul-smelling gases, affecting surrounding air quality and residents' lives. Therefore, the harmless treatment and resource utilization of livestock and poultry breeding waste has become a key bottleneck restricting the sustainable development of the livestock industry.

[0003] Currently, the mainstream treatment methods for livestock and poultry breeding waste in the industry mainly include two traditional models: aerobic fermentation (composting) and anaerobic fermentation (biogas projects). However, both models have revealed insurmountable technical defects in practical applications, specifically:

[0004] Aerobic fermentation: This method commonly employs simple pile-up or windrow-style turning processes, which are essentially only partial decomposition processes of organic matter. Due to the lack of an efficient microbial initiation system and refined process control, the degradation of organic matter is insufficient and fermentation is incomplete. The resulting product still contains a large number of easily decomposable organic components, which will continue to undergo secondary fermentation in the soil after being applied to farmland, releasing heat and organic acids, which can easily cause root and seedling burn in crops, resulting in serious economic losses.

[0005] Anaerobic fermentation: While this method can recover some energy by producing biogas through anaerobic digestion, it requires a large initial investment in engineering facilities, and its operation is subject to stringent requirements regarding temperature, pH, and carbon-to-nitrogen ratios, resulting in high maintenance costs. More importantly, the organic matter conversion efficiency of anaerobic fermentation is limited, and the resulting byproducts—biogas residue and biogas slurry—remain bulky and contain a large amount of undegraded organic matter and potential pathogens. These require secondary treatment processes such as dehydration, drying, and subsequent aerobic composting before they can be safely returned to the field. This leads to a lengthy overall process chain, high energy consumption, and low resource utilization rate.

[0006] Meanwhile, due to long-term continuous cropping and over-reliance on chemical fertilizers while neglecting the input of organic fertilizers, the organic matter content of farmland soils has continued to decline, leading to widespread soil compaction, acidification, and salinization. Soil microbial flora is also imbalanced, resulting in severe soil fertility degradation. This "leanening" of arable land directly leads to reduced fertilizer utilization, weakened crop resistance, and a decline in agricultural product quality, creating a vicious cycle of "increased chemical fertilizer application → soil degradation → further increased chemical fertilizer application." Therefore, the demand for high-quality organic fertilizers that can improve soil fertility and structure is extremely urgent at the planting end. Summary of the Invention

[0007] This invention aims to provide a method for producing high-efficiency ecological fertilizer from livestock and poultry breeding waste. It fundamentally alters and reconstructs the organic structure of livestock and poultry breeding waste (manure), achieving efficient pyrolysis of organic matter, complete inactivation of pathogens, and optimized nutrient forms through a composite microbial community and targeted catalytic process. This yields high-quality organic fertilizer that enriches soil fertility and improves soil structure, realizing the safe and efficient transformation of livestock and poultry breeding waste (manure) from a "pollution source" to a "resource." This invention solves the problems in the background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A method for producing high-efficiency eco-fertilizer from livestock and poultry breeding waste includes the following steps:

[0010] (1) Mix livestock and poultry breeding waste with organic auxiliary materials in proportion, add compound microbial agents, stir evenly to adjust the moisture content and carbon-nitrogen ratio of the materials, and obtain a mixture suitable for fermentation;

[0011] (2) The mixture obtained in step (1) is piled up for primary fermentation. The pile is controlled by turning it over regularly, so that it goes through a heating period, a high temperature period and a cooling period. The vigorous activity of microorganisms is used to rapidly degrade organic matter, and the continuous high temperature is used to kill pathogens and weed seeds to obtain the initial fermentation material.

[0012] (3) The initial fermentation material obtained in step (2) is subjected to static post-maturation aging to further stabilize the recalcitrant organic matter, promote the deep polymerization of humus, eliminate plant toxic substances, and obtain fully decomposed fermented material.

[0013] (4) Crush the fermented material obtained in step (3) and mix it evenly with the functional microbial agent. Then carry out secondary transformation culture. When the mycelium of the functional microbial agent appears in the material, it indicates that the functional microbial agent has been successfully colonized and propagated, and the desired high-efficiency ecological fertilizer is obtained.

[0014] Further, in step (1), the livestock and poultry breeding waste is fresh chicken manure with an initial moisture content of 70%~75%; the organic auxiliary material has a particle size of 0.5~2cm and an initial moisture content of 25%~35%; the mixing weight ratio of the livestock and poultry breeding waste to the organic auxiliary material is 10:3, and the resulting mixture has a moisture content of 55%~60%. The organic auxiliary material is one of straw, rice husks, or sawdust. This ratio adjusts the initial moisture content and carbon-nitrogen ratio of the mixture, providing an optimal environment for the rapid proliferation of subsequent aerobic fermentation microorganisms.

[0015] Further, in step (1), the amount of the compound microbial agent added is 0.08%~0.12% of the total weight of the livestock and poultry breeding waste and organic auxiliary materials, and the effective viable count of the compound microbial agent is not less than 5×10⁻⁶. 9 CFU / g. The compound microbial agent comprises Bacillus subtilis, Bacillus licheniformis, and actinomycetes, with an effective viable count ratio of 3:2:1. Bacillus subtilis and Bacillus licheniformis can rapidly activate and secrete large amounts of extracellular enzymes such as proteases and cellulases within 48 hours, efficiently degrading large molecular organic matter such as proteins and cellulose in chicken manure. Actinomycetes exert a strong antagonistic effect by producing antibiotic-like substances, effectively inhibiting the proliferation of pre-existing putrefactive bacteria and pathogens (such as Escherichia coli) in the material, and significantly reducing the production of odors (such as ammonia and hydrogen sulfide) in the early stages of fermentation.

[0016] Further, in step (2), the primary fermentation includes: a heating period in which the temperature of the pile is raised from the ambient temperature to 55°C within 48 hours; a high-temperature period in which the temperature of the pile is maintained in the range of 55°C to 65°C for 7 to 10 days; and a cooling period in which the temperature of the pile naturally drops to below 45°C. When the material has a dark brown appearance, loose texture, and no obvious odor, the primary fermentation is completed.

[0017] Furthermore, in step (2), the turning operation is carried out once every 24 hours during the heating period and the initial stage of high temperature, and the turning depth is 1.0~1.5m. Turning can dissipate excess moisture and prevent moisture accumulation from causing local hypoxia; it can also increase the specific surface area of ​​the material, allowing the material to fully contact the air and supply oxygen for aerobic microorganisms; it can also allow the material in different parts of the pile to exchange positions, ensuring uniform fermentation.

[0018] Furthermore, in step (3), the static post-ripening and aging time is 8-12 days, and no turning operation is performed during the static post-ripening and aging period. This allows the recalcitrant organic matter (such as some lignin) to decompose slowly, consolidating the harmless treatment effect.

[0019] Further, in step (4), the amount of the functional microbial agent added is 0.5% to 1.0% of the total weight of the fermented material, and the secondary transformation culture time is 4 to 6 days. The functional microbial agent is Bacillus subtilis, Bacillus coagulans, and Bacillus mucilaginosus, and the effective viable count of the functional microorganisms in the high-efficiency ecological fertilizer product is not less than 0.2 billion / gram. Bacillus subtilis secretes antibiotics to inhibit pathogens, playing a dominant role and being completely killed by high temperatures. At this time, Bacillus coagulans begins to take over, and Bacillus mucilaginosus decomposes mineral phosphorus and potassium, releasing nutrients and coagulating to colonize the rhizosphere, forming a dominant microbial community, thereby inhibiting soil-borne diseases and promoting plant growth.

[0020] The beneficial effects of the technical solution are:

[0021] 1. This invention provides a method for producing high-efficiency ecological fertilizer from livestock and poultry breeding waste. In step (1), a specific ratio of compound microbial agent (Bacillus subtilis, Bacillus licheniformis and actinomycetes in a ratio of 3:2:1) is introduced. Combined with the high-temperature process control of "55℃~65℃ for 7~10 days" in step (2), the pathogens, parasite eggs and weed seeds in the material are completely inactivated. The product was tested and found to have a 100% mortality rate of roundworm eggs and a fecal coliform count below the detection limit. At the same time, the antagonistic effect of actinomycetes significantly inhibited the reproduction of putrefactive bacteria, thus solving the technical problems of low harmlessness, serious odor pollution and high biosafety risk of traditional composting.

[0022] 2. This invention provides a method for producing high-efficiency ecological fertilizer using livestock and poultry breeding waste. In step (3), a static post-ripening and aging process lasting 8 to 12 days is used to enhance the harmlessness effect by utilizing the secondary heating generated by the continuous decomposition of recalcitrant organic matter, so that the humus is fully aggregated and the plant toxic substances are completely eliminated. The resulting product has a seed germination index (GI) of over 71.1%. In step (4), the fully decomposed fermented material is subjected to secondary inoculation and short-term transformation culture of functional bacteria, realizing the functional upgrade of organic fertilizer products from "single nutrient supply" to "nutrient supply + biological regulation". The effective live bacteria count of functional bacteria in the finished product is not less than 0.2 billion / gram, which has the dual effects of biological fertilizer and soil conditioner, solving the shortcomings of traditional organic fertilizers with single function and limited effect on improving the soil micro-ecological environment.

[0023] 3. This invention provides a method for producing high-efficiency ecological fertilizer from livestock and poultry breeding waste. After testing and verification, the product (high-efficiency ecological fertilizer) has an organic matter content of 35.5% and a total nutrient content of 7.31%. The content of various heavy metals is far below the national limit standards and meets the requirements of "NY / T 525~2021 Organic Fertilizer". This invention solves the industrialization obstacles of traditional workshop-style composting products, such as large quality fluctuations and difficulty in commercialization and market access.

[0024] 4. This invention provides a method for producing high-efficiency ecological fertilizer using livestock and poultry breeding waste. Field comparative trials show that, compared with conventional chemical fertilizer planting methods, applying the product of this invention (high-efficiency ecological fertilizer) can increase crop yield by 59% and net profit by 45.7%. Simultaneously, key nutritional and functional quality indicators in crops, such as polysaccharides, total sugars, amino acids, and total flavonoids, are significantly improved, resolving the contradiction of traditional fertilizers in simultaneously increasing yield and improving quality. Furthermore, experimental data shows that after applying the product of this invention (high-efficiency ecological fertilizer), soil organic matter content increases by 4.77 times, total nitrogen and available nitrogen content increase by 4.13 times and 25.8 times respectively, total phosphorus and available phosphorus content increase by 7.84 times and 3.77 times respectively, and total potassium and available potassium content increase by 1.36 times and 2.78 times respectively. This achieves an organic combination of "land use" and "soil maintenance," solving fundamental problems such as soil fertility decline and soil compaction caused by long-term reliance on chemical fertilizers.

[0025] 5. This invention provides a method for producing high-efficiency ecological fertilizer from livestock and poultry breeding waste. Through a three-stage coupled process of "rapid high-temperature sterilization with compound microbial agents," "deep humification through post-ripening aging," and "secondary energization with functional microbial agents," it achieves a fundamental reconstruction of the material form, nutrient form, and biological activity from raw materials to products. This solves the industry pain point of insufficient organic matter degradation and incomplete composting in traditional fermentation processes, which leads to secondary fermentation, heat release, and organic acid release after the product is applied to farmland, causing root and seedling burn in crops. Furthermore, it efficiently transforms livestock and poultry waste, a potential "pollution source," into high-quality "resources," achieving high-value recycling of agricultural waste. The process is stable, highly controllable, and economically feasible, and has been successfully applied in industrial-scale production. It solves the technical and economic problems of traditional anaerobic fermentation processes, which involve high investment, high operating costs, and long-term losses, as well as the extensive, inefficient, and low-value-added products of aerobic fermentation processes. This is of great significance for promoting the green, low-carbon, and circular development of agriculture. Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the embodiments:

[0027] Example 1: A method for producing high-efficiency eco-fertilizer using livestock and poultry breeding waste, comprising the following steps:

[0028] (1) Mix livestock and poultry breeding waste with organic auxiliary materials in proportion, add compound microbial agents, stir evenly, adjust the moisture content and carbon-nitrogen ratio of the materials to obtain a mixture suitable for fermentation;

[0029] (2) The mixture obtained in step (1) is piled up for primary fermentation. The pile is controlled by turning it over regularly, so that it goes through a heating period, a high temperature period and a cooling period. The vigorous activity of microorganisms is used to rapidly degrade organic matter, and the continuous high temperature is used to kill pathogens and weed seeds to obtain the initial fermentation material.

[0030] (3) The initial fermentation material obtained in step (2) is subjected to static post-maturation aging to further stabilize the recalcitrant organic matter, promote the deep polymerization of humus, eliminate plant toxic substances, and obtain fully decomposed fermented material.

[0031] (4) Crush the fermented material obtained in step (3) and mix it evenly with the functional microbial agent. Then carry out secondary transformation culture. When the mycelium of the functional microbial agent appears in the material, it indicates that the functional microbial agent has been successfully colonized and propagated, and the desired high-efficiency ecological fertilizer is obtained.

[0032] Example 2: A process for producing high-efficiency ecological fertilizer from livestock and poultry breeding waste using compound microbial agents. This example utilizes fresh chicken manure and straw powder to produce high-efficiency ecological fertilizer. The specific steps are as follows:

[0033] (1) Raw material mixing and inoculation with microbial agent: Take 1000 kg of fresh chicken manure with a moisture content of 70% and 300 kg of straw powder with a moisture content of 30% and a particle size of 0.5~2 cm, and put them into a horizontal mixer together; at the same time, evenly sprinkle 1 kg of compound microbial agent onto the material in the mixer. The effective viable count of the compound microbial agent is 5×10 9 The effective viable count ratio of Bacillus subtilis, Bacillus licheniformis, and actinomycetes in this compound microbial agent is 3:2:1 (CFU / g). The mixture was stirred until homogeneous, resulting in a mixture with a moisture content of 55% and a carbon-to-nitrogen ratio of approximately 25:1.

[0034] (2) Primary fermentation: The mixture obtained in step (1) is transferred to the fermentation tank and piled up to a height of 1.8m and a width of 8m. Within 48 hours of the start of fermentation, the pile temperature rises from the ambient temperature (about 20℃) to 55℃. During this period, the pile is turned over once every 24 hours to a depth of 1.3m. Then, the high-temperature period begins, and the temperature is maintained between 55℃ and 65℃ by controlling the frequency of turning the pile for 9 days. On the 15th day, the pile temperature drops to 42℃, and the material is dark brown, loose, and odorless, indicating that the primary fermentation is complete.

[0035] (3) Post-fermentation aging: The material processed in step (2) is transferred to the aging workshop and statically stacked for 10 days for post-fermentation. After aging, the material is fully decomposed and all decomposition indicators are qualified.

[0036] (4) Functional enhancement: After the material temperature drops below 40℃, crush it. Spray Bacillus subtilis, Bacillus coagulans and Bacillus gelatinosa at a ratio of 0.8% of the total weight of the crushed material and stir evenly. After stacking for 5 days, a second conversion is carried out. On the 5th day, a large number of white mycelia can be seen inside the material.

[0037] (5) Finished product: After the material is crushed and sieved, and passes the inspection, the high-efficiency ecological fertilizer is obtained. The product is tested and found to contain 35.5% organic matter, 7.31% total nutrients, and 0.23 billion / g of effective live bacteria.

[0038] Example 3: Field Application Effect Comparison Trial

[0039] To verify the actual application effect of the product (high-efficiency ecological fertilizer) prepared in Example 2, two experimental fields with basically the same environmental factors such as soil conditions, light and water sources were selected in the same area and used as demonstration fields and control fields, respectively, to conduct crop planting comparison experiments.

[0040] Experimental Design

[0041] Demonstration field: The high-efficiency ecological fertilizer produced in Example 2 was applied as base fertilizer at a rate of 400 kg / mu, and no other chemical fertilizers were applied during the crop growth period.

[0042] Control field: Use conventional commercially available compound fertilizer as base fertilizer at a rate of 350 kg / mu, and apply nitrogen fertilizer such as urea at a rate of 50 kg / mu during the growing season according to the local farmers' conventional planting habits.

[0043] Test crops: Select the same variety of economic crops (medicinal or high-value-added plants that can be tested for quality indicators such as total flavonoids and polysaccharides at the same time).

[0044] Planting management: Other field management measures (such as sowing time, irrigation frequency, weeding, pest and disease control, etc.) were kept completely consistent between the two experimental fields.

[0045] Results and Analysis

[0046] During the crop harvest period, crop yield, quality indicators, and soil physicochemical properties after planting were sampled and tested in both the demonstration field and the control field. The specific comparative data are shown in the table below:

[0047]

[0048] in conclusion

[0049] The comparative experimental data above clearly demonstrate that, compared with conventional fertilizer-based planting methods, the high-efficiency eco-fertilizer produced in Example 2 has the following significant advantages:

[0050] Significantly improves crop quality: The content of key nutrients and functional components such as polysaccharides, total sugars, amino acids, and total flavonoids in crop fruits are significantly increased, indicating that this organic fertilizer can promote the synthesis and accumulation of more beneficial substances in crops.

[0051] Significantly increased yield and economic benefits: The yield per mu in the demonstration field increased by 59% compared to the control field, and the net profit increased by 45.7%. This shows that the fertilizer produced in Example 2 can not only replace chemical fertilizers to meet the needs of crop growth, but also achieve increased yield and income through comprehensive effects such as improving the rhizosphere environment and enhancing crop resistance.

[0052] Effective improvement of soil fertility: After applying the ecological fertilizer of Example 2, the content of soil organic matter and the total and available nutrients of nitrogen, phosphorus, and potassium all increased by several to dozens of times. This proves that the fertilizer produced by this method is rich in active organic matter and beneficial microorganisms. After being applied to the soil, it can continuously carry out biochemical reactions, promote the formation of soil aggregate structure, activate the inherent nutrients of the soil, fundamentally solve the problem of "lean" arable land and soil fertility decline, and realize the combination of "land use" and "land maintenance".

[0053] Example 4: Industrialized Production and Product Quality Compliance Verification

[0054] To verify the industrial application of the product (high-efficiency ecological fertilizer) prepared in Example 2, and to conduct third-party testing on the product.

[0055] 1. Adjustment of industrial production process parameters: In large-scale production, the process flow is the same as in Examples 1 or 2, but the main fermentation cycle can be optimized and adjusted according to the season. For example, in the high-temperature environment of summer, the main fermentation cycle can be shortened to 8 days; in the low-temperature environment of winter, the main fermentation cycle can be extended to 15 days. The aging and maturation cycle is uniformly controlled at 20 days, during which the maximum temperature of the material can reach 78℃, further ensuring the harmlessness effect.

[0056] 2. Product Quality Testing: The powdered product manufactured using this industrial production line (manufacturer: Sichuan Chuhao Biotechnology Development Co., Ltd.) was submitted to Sichuan Lancheng Testing Technology Co., Ltd., which has CMA certification, for full-item testing according to the standard "NY / T 525~2021 Organic Fertilizer". The test report (No.: TW2401~00443) concluded that the tested items with finite limits meet the requirements of NY / T 525~2021. Key indicators are as follows:

[0057] Organic matter (on a dried basis): 35.5% (standard requirement ≥30%).

[0058] Total nutrients (N+P2O5+K2O, on a dried basis): 7.31% (standard requirement ≥4.0%).

[0059] Moisture content (fresh sample): 27.28% (standard requirement ≤30%).

[0060] Seed germination index (GI): 71.1% (standard requirement ≥70%).

[0061] Ascaris egg mortality rate: 100% (standard requirement ≥95%).

[0062] Five heavy metals (As: 8.4 mg / kg ≤ 15 mg / kg, Hg: 8.6 × 10⁻⁶) -2 The levels of Pb (22.4 mg / kg ≤ 50 mg / kg), Cd (not detected (limit of quantitation: 1.6 mg / kg) ≤ 3 mg / kg), and Cr (55 mg / kg ≤ 150 mg / kg) were all far below the standard limits.

[0063] Appearance: Uniform appearance, powdery, no foul odor.

[0064] The test report fully demonstrates that the products produced by the method of this invention not only have advanced technical indicators, but are also safe and compliant, and fully meet the conditions for commercial market access.

[0065] Therefore, it can be seen that the method of producing high-efficiency ecological fertilizer from livestock and poultry breeding waste of the present invention can effectively transform breeding waste into high-quality, high-safety, and multifunctional ecological fertilizer through the formulation of microbial agents and refined segmented process control.

[0066] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific technical solutions or characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
