Description

Technical Field

[0001] This invention belongs to the field of agricultural carbon emission reduction technology, and involves the cross-technology of agricultural carbon emission reduction and high-efficiency planting, specifically involving a synergistic system and method for carbon emission reduction and yield increase in paddy fields. Background Technology

[0002] Existing carbon reduction technologies for paddy fields face three major bottlenecks: first, the inhibitory effect of single microbial technologies on methanogens is unstable and easily affected by the environment; second, the synergy between water-saving irrigation technologies and fertilizer absorption is poor, making it difficult to simultaneously achieve emission reduction and yield increase; and third, there is a lack of a complete chain solution from emission monitoring to carbon asset conversion. Therefore, there is an urgent need to build an integrated system that combines multiple technologies and is controllable throughout the entire lifecycle. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a system and method for synergistic carbon emission reduction and yield increase in paddy fields, which solves the problems of asynchronous methane emission reduction and yield increase in paddy fields, low water resource utilization, incomplete carbon cycle, and difficulty in directly using monitoring data for carbon trading in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A synergistic system for carbon reduction and yield increase in paddy fields, characterized in that it includes: Specialty microbial fertilizer preparation module: Using livestock farm manure as raw material, a special microbial fertilizer containing a special type of Enterococcus faecalis EC11 is selectively cultivated through microbial fermentation technology, wherein the concentration of EC11 bacteria is ≥5×10⁻⁶. 7 The CFU / g of this bacterium was found to be 1.5-2 times that of methanogens in paddy field environments. Fullerene water activation module: The irrigation water is treated by a filter tube (diameter 40-60mm, length 0.8-1.2m) with fullerene resin loaded on the inner wall. The filter tube can generate far-infrared waves with a peak wavelength of 10μm±0.5μm and a main wavelength of 4-14μm, which reduces the size of water molecule clusters to 1 / 3-1 / 2 of that of conventional water. Multi-dimensional monitoring module: It consists of a fixed methane sensor (detection accuracy ≤0.1ppm), a drone scanning monitor (scanning frequency ≥1 time / hour) and an environmental parameter acquisition terminal. It can generate dynamic methane emission curves and crop growth databases in real time and connect to the carbon emission trading platform. Straw carbon conversion module: Through in-situ fermentation (15-20 days at 30-35℃) and carbonization (low-temperature carbonization at 350-450℃), rice straw is converted into small-molecule carbon fertilizer with a carbon content of ≥40%, which can increase soil organic matter by 10%-15% after being returned to the field.

[0005] In the special microbial fertilizer preparation module, EC11 bacteria compete with methanogens for carbon sources and nutrients in the anaerobic environment of paddy fields, forming dominant colonies (colony percentage ≥ 60% within 7 days), thereby inhibiting the metabolic activity of methanogens.

[0006] The small molecule water treated by the fullerene water activation module has a conductivity that is 20%-30% lower than that of conventional irrigation water, and can generate 3,300-6,250 negative ions / cc under vibration conditions, which can promote the proliferation rate of EC11 bacteria by 15%-20%.

[0007] The background data system of the multi-dimensional monitoring module has an automatic verification function, which can generate emission reduction reports that meet the trading standards in accordance with the requirements of the "Interim Measures for the Administration of Voluntary Greenhouse Gas Emission Reduction Trading", with a data error rate of ≤2%.

[0008] A method for reducing carbon emissions and increasing yield in paddy fields, characterized by comprising the following steps: S1. Experimental field zoning: The experimental field is divided into EC11+fullerene synergistic zone, EC11 single factor zone, fullerene single factor zone, and blank control zone. Each zone is separated by an anti-seepage isolation zone (depth ≥ 50cm). S2. Application of microbial fertilizer: In the synergistic zone and the EC11 single factor zone, apply 50-80 kg / mu of special microbial fertilizer according to the soil organic matter content gradient of 1.5%-3.0%, and apply it at a depth of 5-10 cm in the topsoil layer. S3. Activated Irrigation: Small molecule irrigation water is introduced into the synergistic zone and the fullerene single factor zone through the fullerene filter tube, reducing the amount of irrigation per irrigation by 20% compared to the conventional method and shortening the irrigation cycle by 1-2 days. S4. Full-cycle monitoring: From the tillering stage to the maturity stage, methane emission data is collected daily (fixed sensors every 30 minutes, and drones scan 3 times a day), and rice panicle development parameters are recorded simultaneously; S5. Straw treatment: Straw crushing (particle size ≤ 5cm) shall be completed within 3 days after harvesting. Microbial fertilizer residue shall be used as fermentation inoculum (addition amount 5%). The amount of carbon fertilizer returned to the field after carbonization shall be 30% of the fresh weight of straw.

[0009] In step S3, the water flow velocity in the fullerene filter tube is controlled at 0.6-0.8 L / (m²・h), and the pipe is arranged in a "serpentine" shape to extend the water contact time to 15-20 seconds.

[0010] The beneficial effects of this invention are: Synergistic emission reduction effect: The competitive inhibition of EC11 bacteria and the environmental optimization of small molecule water work synergistically to reduce methane emissions by 15%-20% compared with the blank area, which is better than single technology.

[0011] Resource recycling and value enhancement: The utilization rate of manure reaches 100%, the carbon conversion rate of straw is ≥80%, and the amount of chemical fertilizer used can be reduced by 30kg per mu, saving 800-1200 yuan per year based on the current market price.

[0012] Carbon assets can be quantified: monitoring data is directly connected to the carbon trading platform, and the verified emission reductions can be traded at 60 yuan / ton, with an annual increase in carbon revenue of 200-300 yuan per mu.

[0013] The core of this invention lies in a synergistic "biological-physical" carbon reduction pathway: EC11 bacteria inhibit methanogens by occupying ecological niches, while fullerene-treated small-molecule water not only optimizes the soil microenvironment (reducing bulk density by 12%), but also promotes the metabolic activity of EC11 bacteria (increasing respiration rate by 25%), creating a synergistic effect of 1+1>2. Simultaneously, a carbon monitoring and trading system is pre-embedded in the planting process, achieving for the first time a "planting as trading" model for paddy field carbon assets.

[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0019] This system achieves synergistic effects through four core modules: Special microbial fertilizer preparation module: The innovation lies in the directional fermentation of farm manure through EC11 bacteria (30℃ constant temperature, pH 7.0±0.2), so that the competition coefficient between EC11 bacteria and methanogens in the microbial fertilizer is ≥1.8, which solves the problem of short-term inhibitory effect of traditional microbial fertilizers.

[0020] Fullerene water activation module: Its innovation lies in the "dual effect" of the fullerene resin filter tube - it reduces water molecule clusters to small molecules through far-infrared waves (NMR half-width ≤60Hz), and reduces the redox potential of water by 50-80mV through the adjustment of the surface charge of the material, thereby promoting the absorption efficiency of nitrogen and phosphorus by rice roots by 15%-20%.

[0021] Multi-dimensional monitoring module: An innovative "point-area" combined monitoring network is designed. Fixed sensors collect instantaneous concentrations at single points, while drones equipped with hyperspectral imagers acquire regional emission averages. After the data is processed by the edge computing terminal, a monitoring report conforming to the VCS standard is directly generated, solving the drawback of traditional data requiring secondary processing.

[0022] Straw carbon conversion module: The co-fermentation technology of "microbial fertilizer residue-straw" is adopted, which shortens the straw decomposition cycle to 15 days, which is 40% faster than the traditional method. In addition, fullerene material is added as a catalyst during the carbonization process, which increases the specific surface area of ​​biocarbon to 200-300m² / g and enhances the soil's carbon sequestration capacity. Example

[0023] 1. Material preparation: EC11 bacterial agent: preserved by freeze-drying (live count 10^6) 9 CFU / g); Fullerene resin filter tube: 50mm diameter, 5% fullerene loading; Monitoring equipment: fixed methane sensor (model MH-9000), drone (DJI M300RTK equipped with thermal imaging camera).

[0024] 2. Experimental Design Four zones were set up in a 4-mu (approximately 0.67 hectares) paddy field in Longyan, Fujian: Synergistic Zone (EC11+Fullerene): Apply 50 kg / mu of special microbial fertilizer and irrigate with fullerene filter pipes; EC11 zone: Same amount of microbial fertilizer + conventional irrigation; Fullerene zone: Conventional fertilization + fullerene irrigation; Blank area: Routine planting and management.

[0025] 3. Key parameter control Application of microbial fertilizer: Spread it evenly 3 days before transplanting, and till it to a depth of 10cm; Irrigation management: In the synergistic zone and fullerene zone, each irrigation lasts 5 hours with a water volume of 20 m³ / mu, which is 20% less than that in the blank zone; Monitoring frequency: Daily monitoring from tillering stage to grain filling stage, increased to 5 times per day during maturity stage.

[0026] 4. Result Verification: Methane emissions: average concentration in the synergistic zone was 2.50±0.02 ppm, and in the blank zone it was 3.05±0.03 ppm, with an emission reduction rate of 18.0%. Yield parameters: 300 grains per panicle in the collaborative zone (280 grains in the blank zone), 1000-grain weight 6.93g (6.55g in the blank zone); Soil improvement: After straw carbon fertilizer was returned to the field, the soil organic matter increased from 2.5% to 2.8%.

[0027] Enterococcus faecalis has a wide range of applications in agriculture, from soil improvement to promoting plant health.

[0028] Organic fertilizer production: Enterococci can be used in the production of organic fertilizers. They are able to decompose organic matter, converting it into nutrients needed by plants, such as nitrogen, phosphorus, and potassium, and improving soil structure and water retention capacity. This helps to improve soil quality and increase crop yield and quality.

[0029] Biological control: Enterococci are widely used in biological control methods. They produce inhibitory substances that can resist a variety of plant pathogens and pests. By using Enterococci as biopesticides, dependence on chemical pesticides can be reduced, and environmental pollution and negative impacts on ecosystems can be minimized.

[0030] Plant growth promotion: Enterococci can form a symbiotic relationship with plant roots, promoting plant growth. They secrete growth hormones and beneficial metabolites, which promote plant growth by increasing nutrient absorption and enhancing stress resistance. This helps to increase crop yield and tolerance.

[0031] Soil remediation: Enterococci have the potential to remediate contaminated or degraded soils. They can decompose organic pollutants such as pesticides and heavy metals, thereby improving soil quality. In addition, Enterococci can reduce soil erosion and water loss, improving soil sustainability.

[0032] Phytonutrient utilization efficiency: Enterococci can improve the efficiency of plant utilization of soil nutrients by regulating the rhizosphere environment. They can dissolve micronutrients such as phosphates and zinc, making them easier for plants to absorb. This helps reduce the use of chemical fertilizers and mitigate the negative environmental impact of agriculture.

[0033] Straw decomposition: Enterococci play a crucial role in straw decomposition and composting. They break down cellulose and hemicellulose in straw, releasing organic matter and nutrients, and accelerating the composting process. This helps reduce straw accumulation and environmental pollution while producing organic fertilizer.

[0034] Agricultural product preservation: Enterococci are widely used in the preservation of agricultural products. They can produce organic acids and other antibacterial substances through fermentation, inhibiting the growth of harmful bacteria in food. Applying Enterococci to food preservation treatment can extend the shelf life of food and reduce food loss.

[0035] Green manure planting: Applying Enterococcus faecalis to green manure planting can promote the accumulation of soil organic matter and improve soil quality. Enterococcus faecalis can convert atmospheric nitrogen into a form usable by crops and, through root symbiosis, provide organic acids and other hormones to promote plant growth.

[0036] Suppressing methanogens: Based on the above effects, EC11 has roughly the same growth and reproduction conditions as methanogens, but in the paddy field environment, the proliferation rate of EC11 is much higher than that of methanogens, thus rapidly forming colonies and becoming the dominant colonies in the paddy field. Methanogens are thus suppressed and find it difficult to proliferate, thereby reducing methane emissions.

[0037] Fullerene filter tube: Fullerene filter tubes treated with special patented technology can generate waves with peak wavelengths in the far-infrared region (≒10μm), a main wavelength band between 4 and 14μm, and a secondary band known as the photoelectron propagation band (e.g., Figure 3 The photoelectron propagation band has the most suitable wavelength for the growth of living organisms such as plants and animals, and also affects soil and air, and is closely related to crop growth.

[0038] Progress status one month after adding bacterial agent using fullerene filter tubes: as follows Figure 2 As shown, The relevant methane detection equipment and various paddy field management and field data acquisition equipment are basically ready and are undergoing final debugging and trial operation. Valid data will soon be generated for data processing and statistics after the rice harvest, as well as a summary report of the methodology and related applications and certifications. After irrigation using fullerene filter pipes and the addition of an appropriate amount of EC11 microbial fertilizer, the rice has now entered the grain-filling stage. We randomly selected rice panicles from the experimental area and the control area for preliminary measurement and comparison: Figure 2 In the blank areas of the first and second left images, each rice ear has 280 grains. Figure 2 The first and second right images show 300 grains in the test area; The total weight of rice grains per panicle in the blank area was 6.55 grams, while in the experimental area it was 6.93 grams.

[0039] The working principle of small molecule water: Small molecule water can eliminate the electrical charge in the soil, making the soil clumps smaller and looser; plant roots can gain more space to grow, and the root system becomes longer, allowing them to obtain more nutrients; small molecule water is not oxidizing water but reducing water, and many insects that dislike neutral electrical environments will not stay in soil treated with small molecule water; small molecule water has very small water molecule clusters, making it easy for plants to obtain soil nutrients; small molecule water has no electrical tendency and can provide plants with any minerals and nutrients. Figure 4 As shown.

[0040] The methane emission data and trends in the experimental area (Table 1) and the blank area (Table 2) are consistent with our predictions, and the methane emissions in the experimental area are significantly lower than those in the blank area.

We will also apply for certification through methodology to ultimately enable the trading of carbon reductions.

[0042] Example: Field planting experiment of watermelon seeds harvested in Xinjiang: A field planting experiment of watermelon was launched in Xinjiang Production and Construction Corps (50 mu each for the experimental group and the control group). The purpose was to test the effect of fullerene resin pipes on reducing the molecular size of irrigation water to achieve water and fertilizer retention (liquid fertilizer) or water conservation. Each drip irrigation lasted 5 hours. The experimental group had 4 more bends in the water pipes, and the pipes contained fullerene material. The water consumption was 20% less than that of the control group, but the melon seedlings were more vigorous. This confirmed that the water-saving effect was significant.

[0043] Meanwhile, small-molecule water easily passes through plant cell membranes, promoting plant absorption, digestion, and growth, thereby increasing yield and income. After two and a half months, the experimental group produced 15% more seeds than the control group. Figure 5 As shown.
