Description

Technical Field

[0001] This invention relates to the field of soil carbon technology, specifically to a method for efficient soil carbon storage. Background Technology

[0002] Soil carbon includes inorganic carbon and organic carbon. Soil organic carbon refers to various positively valence carbon-containing organic compounds in the soil. It is an extremely important component of soil, not only closely related to soil fertility, but also having a huge impact on the Earth's carbon cycle. It is both a source and an important sink of greenhouse gases. Soil organic carbon is not only very complex in composition and structure, but also in complex and diverse in its cycling and transformation processes. During land use, soil carbon is easily lost, and it is impossible to effectively store soil carbon efficiently. Summary of the Invention

[0003] The purpose of this invention is to provide a method for efficient soil carbon storage, in order to solve the problem mentioned in the background art that soil carbon is easily lost during land use and cannot be effectively stored efficiently.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for efficient soil carbon storage, comprising establishing a land sample zone, measuring the sample zone, analyzing the sample zone, using salt-tolerant and alkali-tolerant organisms, exogenous organic materials, soil conditioners, and conditioning agents; characterized by comprising the following steps: Step 1: Establish land sample zones and at least one project area, with each project area containing at least one sample zone; Step 2: Sample strip measurement, and conduct management activities within the project area to increase soil carbon sequestration; Step 3: Analyze the sample zones. Based on the measured soil parameters, calculate the net change in soil carbon density of each sample zone in each project area, the total net change in soil carbon density of all sample zones in all project areas, and the contribution of the carbon sink reserve buffer zone. Step 4: Use salt-tolerant and alkali-tolerant organisms for single-seed sowing. Step 5: After the sowing and harvesting of salt-tolerant and alkali-tolerant organisms, the exogenous organic materials are dumped. Step Six: Soil Amendment. The soil carbon amendment is prepared by mixing the following substances according to the following mass percentages: 20% composite polymer organic hydrosol, 10%-20% humic acid, 30%-40% diammonium hydrogen phosphate, 20% biuret and urea-formaldehyde slow-release fertilizer, 5% nutrients, and water as the remainder. Step 7: Conditioning agent. Inert carbon is compounded with chemical fertilizer or manure in a certain proportion to develop a new type of passivated fertilizer, which allows soil carbon to be slowly released in the soil, improves soil carbon utilization, increases crop yield and income, and reduces soil carbon loss.

[0005] Preferably, at least one measurement point is selected within each sample band, and the soil parameters at the measurement point are measured and recorded.

[0006] Preferably, after the operation, the soil parameters at the measurement point are measured and recorded again.

[0007] Preferably, the sample band is analyzed, and the contribution of the carbon sink reserve buffer is the difference between the total net change in soil carbon density and the claimed net change in soil carbon density; if the total net change in soil carbon density is greater than the claimed net change in soil carbon density, the net change in soil carbon density is quantified as soil carbon storage and then as a carbon offset value; wherein, the carbon offset value is used to calculate carbon emission allowances and manage the carbon sink reserve buffer in order to counterbalance the volatility of soil carbon sequestration associated with each project area.

[0008] Preferably, the seed row spacing is 8cm and the plant spacing is 5-7cm. Sowing is done in well-drained soil at a depth of 5-7cm. After sowing, the soil is compacted. In this cultivation method, for salt-tolerant organisms with a population of less than 400,000 during the greening period, timely watering and fertilization are required. For salt-tolerant organisms with a population of 300,000-500,000 during the greening period, watering and fertilization are required at the early jointing stage. For salt-tolerant organisms with a population of more than 800,000 during the greening period, watering and fertilization are required in the middle and late jointing stages.

[0009] Preferably, the organic material in the container is pulped and crushed to obtain a first pulped material. A predetermined amount of water is added to dilute the first pulped material to obtain a second pulped material. The second pulped material is fed into a reaction vessel and subjected to a wet hydrolysis reaction in a second temperature environment to obtain humic acid solution. The humic acid solution is added to a flash evaporation device to precipitate excess water and obtain humic acid organic particles.

[0010] Preferably, the soil carbon amendment is prepared by mixing the following substances in the following mass percentages: 20% composite polymeric organic hydrosol, 40% humic acid, 10% diammonium hydrogen phosphate, 10% biuret and urea-formaldehyde slow-release fertilizer, 35% nutrients, and water as the remainder. The nutrients are potassium fertilizer, with potassium fertilizer being the most effective. Other micronutrients may also be selected.

[0011] Preferably, the conditioner used is a product with extremely rich carbon content and stable properties, which is produced by the pyrolysis and carbonization of biomass at 400-600℃ under completely or partially anaerobic conditions. It has a well-developed pore structure, strong adsorption characteristics and high stability. It can not only improve soil pH and soil moisture content and improve soil structure, but also increase soil organic matter content, increase the content of nitrogen, phosphorus, potassium, calcium, magnesium and other elements in the soil, increase soil carbon sequestration capacity and crop yield, etc.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: the land is initially improved by using salt-tolerant and alkali-tolerant organisms, and then further improved by applying organic fertilizer, planting green manure, and returning straw to the field. Then, the land is further improved by using organic materials such as high humus, starch, lignin, and protein. Finally, the land is conditioned by using carbon-rich biomass pyrolysis inert biochar and functional mineral materials, thereby improving the efficient storage effect of soil carbon. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of a method for efficient soil carbon storage according to the present invention. Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Example 1: Please refer to Figure 1 This invention provides a technical solution: a method for efficient soil carbon storage, comprising establishing land sample zones, measuring the sample zones, analyzing the sample zones, using salt-tolerant and alkali-tolerant organisms, exogenous organic materials, soil conditioners, and conditioning agents; characterized by comprising the following steps: Step 1: Establish land sample zones and at least one project area, with each project area containing at least one sample zone; Step 2: Sample strip measurement, and conduct management activities within the project area to increase soil carbon sequestration; Step 3: Analyze the sample zones. Based on the measured soil parameters, calculate the net change in soil carbon density of each sample zone in each project area, the total net change in soil carbon density of all sample zones in all project areas, and the contribution of the carbon sink reserve buffer zone. Step 4: Use salt-tolerant and alkali-tolerant organisms for single-seed sowing. Step 5: After the sowing and harvesting of salt-tolerant and alkali-tolerant organisms, the exogenous organic materials are dumped. Step Six: Soil Amendment. The soil carbon amendment is prepared by mixing the following substances in percentage by mass: 20% composite polymeric organic hydrosol, 10%-20% humic acid, 30%-40% diammonium hydrogen phosphate, 20% biuret and urea-formaldehyde slow-release fertilizer, 5% nutrients, and water as the remainder.

[0016] At least one measurement point is selected within each sample zone, and soil parameters at these points are measured and recorded. After the operational activities, soil parameters at the measurement points are measured and recorded again. The sample zones are then analyzed. The contribution of carbon sink reserve buffer is the difference between the total net change in soil carbon density and the claimed net change in soil carbon density. If the total net change in soil carbon density is greater than the claimed net change in soil carbon density, the net change in soil carbon density is quantified as soil carbon storage and further quantified as a carbon offset value. The carbon offset value is used to calculate carbon emission allowances and manage carbon sinks. To mitigate the variability of soil carbon sequestration in each project area, a buffer system is established. Seed spacing is 8cm between rows and 5-7cm between plants. Sowing should be done in well-drained soil at a depth of 5-7cm. After sowing, the soil should be compacted. For salt-tolerant organisms with a population of less than 400,000 during the greening period, timely watering and fertilization are necessary. For those with a population of 300,000-500,000 during the greening period, watering and fertilization should be applied at the early jointing stage. For those with a population of more than 800,000 during the greening period, watering and fertilization should be applied in the middle and late jointing stages.

[0017] The organic material in the container is pulped and crushed to obtain a first pulped material. A predetermined amount of water is added to dilute the first pulped material, resulting in a second pulped material. The second pulped material is then fed into a reaction vessel, where it undergoes a wet hydrolysis reaction at a second temperature to obtain a humic acid solution. This humic acid solution is then added to a flash evaporation device to remove excess water, yielding humic acid organic particles. The soil carbon amendment is prepared by mixing the following substances in the following mass percentages: 20% composite polymeric organic hydrosol, 40% humic acid, 10% diammonium hydrogen phosphate, and 10% biuret and urea-formaldehyde slow-release fertilizer. The fertilizer contains 35% nutrients and the remainder is water. The nutrient is potassium fertilizer, which is the most effective. Other micronutrients can also be selected. The conditioner used is a carbon-rich and stable product produced by the pyrolysis and carbonization of biomass at 400-600℃ under complete or partial anaerobic conditions. It has a well-developed pore structure, strong adsorption characteristics, and high stability. It can not only improve soil pH and soil moisture content and improve soil structure, but also increase soil organic matter content, increase the content of nitrogen, phosphorus, potassium, calcium, magnesium, etc. in the soil, increase soil carbon sequestration capacity, and increase crop yield.

[0018] Because no soil conditioning was carried out, soil carbon regulation could not be further improved, which affected the efficient storage of soil carbon, prevented the increase of soil organic matter content, and reduced the content of nitrogen, phosphorus, potassium, calcium, magnesium and other elements in the soil, thus affecting the soil's carbon sequestration capacity and crop yield.

[0019] Example 2: Please refer to Figure 1This invention provides a technical solution: a method for efficient soil carbon storage, comprising establishing land sample zones, measuring the sample zones, analyzing the sample zones, using salt-tolerant and alkali-tolerant organisms, exogenous organic materials, soil conditioners, and conditioning agents; characterized by comprising the following steps: Step 1: Establish land sample zones and at least one project area, with each project area containing at least one sample zone; Step 2: Sample strip measurement, and conduct management activities within the project area to increase soil carbon sequestration; Step 3: Analyze the sample zones. Based on the measured soil parameters, calculate the net change in soil carbon density of each sample zone in each project area, the total net change in soil carbon density of all sample zones in all project areas, and the contribution of the carbon sink reserve buffer zone. Step 4: Use salt-tolerant and alkali-tolerant organisms for single-seed sowing. Step 5: After the sowing and harvesting of salt-tolerant and alkali-tolerant organisms, the exogenous organic materials are dumped. Step Six: Soil Amendment. The soil carbon amendment is prepared by mixing the following substances according to the following mass percentages: 20% composite polymer organic hydrosol, 10%-20% humic acid, 30%-40% diammonium hydrogen phosphate, 20% biuret and urea-formaldehyde slow-release fertilizer, 5% nutrients, and water as the remainder. Step 7: Conditioning agent. Inert carbon is compounded with chemical fertilizer or manure in a certain proportion to develop a new type of passivated fertilizer, which allows soil carbon to be slowly released in the soil, improves soil carbon utilization, increases crop yield and income, and reduces soil carbon loss.

[0020] At least one measurement point is selected within each sample zone, and soil parameters at these points are measured and recorded. After the operational activities, soil parameters at the measurement points are measured and recorded again. The sample zones are then analyzed. The contribution of carbon sink reserve buffer is the difference between the total net change in soil carbon density and the claimed net change in soil carbon density. If the total net change in soil carbon density is greater than the claimed net change in soil carbon density, the net change in soil carbon density is quantified as soil carbon storage and further quantified as a carbon offset value. The carbon offset value is used to calculate carbon emission allowances and manage carbon sinks. To mitigate the variability of soil carbon sequestration in each project area, a buffer system is established. Seed spacing is 8cm between rows and 5-7cm between plants. Sowing should be done in well-drained soil at a depth of 5-7cm. After sowing, the soil should be compacted. For salt-tolerant organisms with a population of less than 400,000 during the greening period, timely watering and fertilization are necessary. For those with a population of 300,000-500,000 during the greening period, watering and fertilization should be applied at the early jointing stage. For those with a population of more than 800,000 during the greening period, watering and fertilization should be applied in the middle and late jointing stages.

[0021] The organic material in the container is pulped and crushed to obtain a first pulped material. A predetermined amount of water is added to dilute the first pulped material, resulting in a second pulped material. The second pulped material is then fed into a reaction vessel, where it undergoes a wet hydrolysis reaction at a second temperature to obtain a humic acid solution. This humic acid solution is then added to a flash evaporation device to remove excess water, yielding humic acid organic particles. The soil carbon amendment is prepared by mixing the following substances in the following mass percentages: 20% composite polymeric organic hydrosol, 40% humic acid, 10% diammonium hydrogen phosphate, and 10% biuret and urea-formaldehyde slow-release fertilizer. The fertilizer contains 35% nutrients and the remainder is water. The nutrient is potassium fertilizer, which is the most effective. Other micronutrients can also be selected. The conditioner used is a carbon-rich and stable product produced by the pyrolysis and carbonization of biomass at 400-600℃ under complete or partial anaerobic conditions. It has a well-developed pore structure, strong adsorption characteristics, and high stability. It can not only improve soil pH and soil moisture content and improve soil structure, but also increase soil organic matter content, increase the content of nitrogen, phosphorus, potassium, calcium, magnesium, etc. in the soil, increase soil carbon sequestration capacity, and increase crop yield.

[0022] Based on Example 1, soil conditioning can further regulate soil carbon, improve soil carbon storage efficiency, increase soil organic matter content, increase the content of nitrogen, phosphorus, potassium, calcium, magnesium and other elements in the soil, and enhance soil carbon sequestration capacity and crop yield.

[0023] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
