Description

Technical Field

[0001] This invention relates to the field of soil organic matter carbon sequestration technology, specifically a method for improving soil organic matter carbon sequestration by increasing photosynthetic efficiency through silicon-titanium composite microorganisms. Background Technology

[0002] Measures to enhance soil carbon sequestration: 1. Promote afforestation. Afforestation effectively slows greenhouse gas emissions, adds more organic carbon to the soil, and increases soil absorption and accumulation, thereby enhancing soil carbon sequestration. 2. Introduce organic agriculture. Organic agriculture can improve soil quality by reducing pesticide use and increasing the application of organic matter, thus promoting the storage of organic carbon in the soil. 3. Control livestock manure emissions. Accumulated livestock manure generates residual heat, which is harmful to the soil and also releases large amounts of greenhouse gases and organic matter, reducing the effective utilization of organic carbon resources in the soil. 4. Adopt water-saving irrigation techniques. Water-saving irrigation techniques can reduce evaporation losses, conserve water, and reduce damage to soil structure, thereby increasing the soil carbon sequestration rate. 5. Increase soil fertility. Appropriate application of organic fertilizers can increase the adsorption of organic carbon and other beneficial elements into the soil, thereby increasing soil quality and improving the organic carbon fixation rate. Existing technologies using microorganisms for carbon fixation are often costly, have low microbial survival rates, poor carbon fixation effects, and require continuous replenishment of microorganisms to prevent them from surviving and multiplying in the soil, resulting in high costs. To address this, a method is proposed that uses silicon-titanium composite microorganisms to increase photosynthetic efficiency and improve soil organic matter carbon fixation.

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a method for increasing photosynthetic efficiency and improving soil organic matter carbon sequestration using silicon-titanium composite microorganisms, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for increasing photosynthetic efficiency and improving soil organic matter carbon sequestration using silicon-titanium composite microorganisms, the specific steps of which are as follows:

[0005] S1: Soil selection and treatment provide suitable environmental conditions for silicon-titanium composite microorganisms;

[0006] S11: After selecting the soil, divide the soil into several 1-meter by 1-meter squares;

[0007] S12: Turn over the soil to a depth of 10-15 cm, breaking up large clumps of soil into smaller clumps, each 3-5 cm in size.

[0008] S13: A drainage ditch is dug at the edge of each square soil block, with a depth of 10-13cm and a width of 15-20cm;

[0009] S2: Mix the silicon-titanium composite microbial strains with the soil;

[0010] S21: Spread the silicon-titanium composite microbial inoculant evenly on the soil surface;

[0011] S22: Till the top 2-3cm of soil to allow the silicon-titanium composite microbial strains to fully contact the soil;

[0012] S23: Spray water on the surface of the soil to regulate soil moisture;

[0013] S3: Provides the soil with a nutrient solution for the survival and reproduction of silicon-titanium composite microorganisms through drip irrigation;

[0014] S31: A ceramic drip irrigation infiltration tube is inserted in the middle of a square soil layer;

[0015] S32: The ceramic drip irrigation permeation pipe has several micropores. The ceramic drip irrigation permeation pipe is connected to the water delivery pipe, and the water delivery pipe is connected to the suction pump on the nutrient tank.

[0016] S33: A solenoid valve is installed on the water supply pipe, which is controlled by a timer and is opened once every 7 days for 5-8 hours each time;

[0017] S4: Regularly add silicon-titanium composite microorganisms to the soil;

[0018] S41: Place the silicon-titanium composite microbial inoculum into a water bucket and stir evenly;

[0019] S42: Spray the water from the bucket onto the soil surface;

[0020] S43: The replenishment cycle for silicon-titanium composite microorganisms is once every 1-2 months.

[0021] As a preferred technical solution of the present invention, in the selection of soil in S1, the soil pH value is detected and the pH value is 6.5 to 7.5, and soil with sufficient sunlight is selected.

[0022] As a preferred embodiment of the present invention, the nutrient solution in S3 includes inorganic salts, organic matter, nitrogen source, phosphorus source and water, with inorganic salts accounting for 5%, organic matter accounting for 6%, nitrogen source accounting for 3%, phosphorus source accounting for 4%, and water accounting for 82%.

[0023] As a preferred embodiment of the present invention, when the silicon-titanium composite microbial inoculant is sown in step S2, the thickness of the silicon-titanium composite microbial inoculant on the soil surface is 1-1.5 mm.

[0024] In a preferred embodiment of the present invention, both the solenoid valve and the timer in S33 are electrically connected to an external power supply.

[0025] As a preferred embodiment of the present invention, in step S4, when adding silicon-titanium composite microorganisms, plants are planted in the middle of the soil and weeds are removed manually.

[0026] The beneficial effects of this invention are as follows: This invention adds silicon-titanium composite microorganisms to the soil. Planting plants with high photosynthetic efficiency and rapid growth rate in symbiosis with silicon-titanium composite microorganisms allows for more uniform distribution of these microorganisms in the soil, enabling continuous growth and reproduction. This eliminates the need for large-scale supplementation of bio-fertilizers, reducing costs. Furthermore, this method increases the survival rate of the silicon-titanium composite microorganisms. Nutrients are provided to the microorganisms through drip irrigation, not only supplying water and nutrients to the plants but also promoting the growth and reproduction of the microorganisms. Plants convert large amounts of carbon dioxide into organic matter through photosynthesis and transfer fixed carbon elements into the soil through root secretions, which can reduce atmospheric CO2 concentration, mitigate global climate change, improve soil quality, and increase organic matter content. Increased organic matter content improves soil structure and water retention capacity, reduces the risk of soil erosion and adverse conditions, increases crop yields, helps reduce the use of chemical fertilizers and pesticides, lowers the negative environmental impact of agriculture, promotes sustainable agriculture and land management practices, and provides more sustainable land use solutions.
