Abstract

The invention relates to an improved carbonization and greening treatment system for desert sand fixation, and belongs to the technical field of desert control improvement. The treatment system includes separation wall construction and soil loosening system, porous pipe embedding system, nutrient matrix and seed spraying system, mulch laying system, aeration carbonization and nutrient solution supply system. The invention forms a high-strength separation wall through spraying and aeration and carbonization of the mixing head, grids a large area of ​​desert, and effectively avoids movement and accumulation of sand dunes. The multiple functions of the porous tube and the plastic film not only realize the rapid carbonization of carbon dioxide on the separation wall, but also solve the adverse effects of the harsh desert environment such as low temperature, drought, barren and windy on the germination and growth of plants; the invention provides an easy-to-operate , Reliable quality, efficient construction, low-carbon and environmentally friendly desert sand-fixing improved carbonization and greening treatment system, while fast sand-fixing, it also realizes the resource utilization of industrial waste and plant greening in the desert, which is conducive to the improvement of the desert ecological environment.

Description

technical field [0001] The invention belongs to the technical field of improvement of desert control in environmental geotechnical engineering, and in particular relates to a carbonization greening treatment system for improvement of desert sand fixation. Background technique [0002] Under the sandy conditions of extremely arid, semi-arid and partially sub-humid regions, affected by natural factors or unreasonable human activities, the ecological balance is destroyed, and wind-eroded landforms and land degradation gradually appear. In order to prevent the expansion of desertification, deserts have been controlled in various ways, and remarkable results have been achieved. However, the traditional governance method has great limitations, and the governance efficiency is relatively low, so it is difficult to popularize and use it. With the development of my country's central and western regions, desert control must not only stabilize the sand and prevent further expansion of...
