Description

Technical Field

[0001] The utility model relates to the technical field related to carbon sink systems, and more specifically, to a multifunctional planting device for fixing and increasing carbon sink in grassland soil. Background Art

[0002] Soil carbon fixation and sequestration research has been an important frontier in soil science research in the past 10 years. It is a measure to increase the carbon content of carbon pools other than the atmosphere. Sustainable management of soil carbon fixation and sequestration is a major need to address climate change and global soil degradation. There are currently two main ways of carbon fixation and sequestration: physical and biological. The physical method is to store carbon dioxide for a long time in exploited oil and gas wells, coal seams and deep seas; the biological method is to use plant photosynthesis to convert carbon dioxide into carbohydrates and fix it in the plant body or soil in the form of organic carbon. In the past 10 years, people have paid more and more attention to nature-based solutions. Biological carbon fixation is considered to be the most promising way to mitigate global warming, the so-called carbon fixation.

[0003] According to the article "Research Progress on Soil Carbon Sequestration Based on Conservation Agriculture" published in the Chinese Journal of Eco-Agriculture in 2022, traditional farming methods represented by plowing mainly affect the SOC fixation process by causing soil erosion and soil and water loss, and the fixation and sequestration of SOC are extremely important in regulating global climate change. Grassland soil carbon fixation and sequestration is the process in which grassland plants absorb carbon dioxide from the atmosphere and fix it in vegetation or soil, reducing the concentration of the gas in the atmosphere. The existing grassland plant planting adopts traditional farming methods represented by plowing, which is not conducive to soil carbon fixation and sequestration. Utility Model Content

[0040] First, the whole device is connected to a traction machine through a traction rod 500 and a U-shaped connection block 501, and the traction machine is used as a power to make the whole device move forward above the soil. During the moving process, various plants or debris on the soil are removed by the mowing blade 304, and then a groove is opened in the soil by the groove opening blade 305;

[0041] As the device moves forward, the soil covering wheel 307 moves on the soil and rotates, and the soil covering wheel 307 drives the rotating shaft 308 to rotate the driving sprocket 407, and the driven chain 409 is driven by the chain 409 to rotate and drive the worm 406 to rotate, and the worm 406 drives the worm 406 meshing with it to rotate the rotating rod 401, and during the rotation of the rotating rod 401, the retaining ring 403 is driven to rotate, and when the retaining ring 403 rotates, the through hole 404 can correspond to or separate from the seed outlet 104 and the fertilizer outlet 105. When the through hole 404 corresponds to the seed outlet 104 and the fertilizer outlet 105, the seeds in the seed chamber 102 can be The fertilizer in the organic fertilizer chamber 103 can pass through the through hole 404 through the seed outlet 104 to enter the sowing tube 106 and be sown in the groove opened by the furrowing blade 305. The fertilizer in the organic fertilizer chamber 103 can pass through the through hole 404 through the fertilizer outlet 105 to enter the fertilizer tube 107 and be sown in the groove opened by the furrowing blade 305. When the through hole 404 is separated from the seed outlet 104 and the fertilizer outlet 105, the seed outlet 104 and the fertilizer outlet 105 are blocked, so as to realize intermittent sowing and fertilization, control the sowing spacing and make the sowing uniform, and the control valve 202 is opened, and the water in the water tank 200 enters the water pipe 201 and is drip-irrigated by the drip irrigation pipe 203;
