Problems solved by technology

[0005] The existing repairing methods using microbial reaction liquid will cause calcium carbonate to penetrate deep into the soil. On the one hand, the calcium carbonate in the upper layer has insufficient bonding density with the soil and has poor erosion resistance. On the other hand, the calcium carbonate in the lower layer will cause soil compaction and affect the plant root growth and nutrient absorption, and a large amount of reaction solution will be wasted, and the cost is higher

Embodiment 1

[0029]Seefigure 1 ,figure 2, A method for ecological restoration and soil erosion control using microbial reaction, including the following steps:

[0030]S1. Loosen the soil on the surface of the soil area to be repaired, and remove weeds;

[0031]S2. Adjust the flatness of the soil area to make the surface more smooth;

[0032]S3. Lay a layer of naturally degradable film on the surface of the soil area. After that, evenly dig holes in the film, and dig out the soil in the holes to form a mosaic pit, and place a natural degradable isolation in the mosaic pit The isolation cylinder is uniformly provided with 1-5 mm through holes; the materials of the film and the isolation cylinder are both polylactic acid, and the degradation rate is fast. The isolation cylinder can also be made into a cylinder with a film, and one end extending into the soil is sealed.

[0033]S4. Evenly spread a layer of organic clay with a thickness of 2-8cm on the surface of the film. A shallow layer of ryegrass seedlings ...

Embodiment 2

[0040]The method of pre-planting ryegrass seedlings on organic clay is:

[0041]Sowing seeds (ryegrass seeds) on the cultivation soil;

[0042]Pave a layer of plastic mesh on the surface;

[0043]After the seeds are grown, the straws pass through the holes of the plastic mesh plate. When the plants grow to a transplantable state, sprinkle a layer of fine soil on the plastic mesh plate to cover the gaps in the holes of the plastic mesh plate;

[0044]Spray the reaction solution once to make the fine soil coarsely solidify to form a thick barrier layer, and the roots of the plants are located under the thick waterproof layer;

[0045]Transplant (continuously cultivate the soil layer and the plastic mesh board together and divide into blocks)

[0046]The effect is that when the reaction solution is sprayed in the later stage, under the action of the coarse barrier layer, the downward infiltration rate of calcium carbonate crystals slows down, which is conducive to the growth of plant roots, and is easy ...

Abstract

The invention discloses a method for carrying out ecological restoration and water and soil loss treatment by utilizing microbial reaction. The method can protect the ecological environment of a sideslope and prevent water and soil loss of the side slope. The method comprises the following steps of S1, loosening soil; S2, leveling; S3, laying a layer of film capable of being naturally degraded, digging a chimeric pit, placing an isolation cylinder capable of being naturally degraded the chimeric pit, and forming a through hole in the isolation cylinder; S4, laying organic matter clay, pre-planting shallow ryegrass seedlings on the organic matter clay, and enabling the positions corresponding to the isolation cylinders to be vacated; S5, placing cultivated setaria viridis seedlings in theisolation cylinder; S6, regularly spraying a reaction solution containing microorganisms, calcium acetate, after degrading the film and the isolation cylinder, enabling the reaction solution to not besprayed any more, enabling the root system to grow naturally and stretch into a soil body area needing to be repaired, and enabling the organic matter clay layer and the soil body area below the organic matter clay layer to form a whole.

Description

Technical field[0001]The invention relates to the technical field of ecological restoration, in particular to a method for ecological restoration and soil erosion control by using microbial reaction.Background technique[0002]During the excavation and construction of the highway, a large number of road slopes will be formed on both sides of the highway, and a large amount of exposed soil will be formed in the process of mining, which will cause ecological environmental damage, water and soil erosion, and economic losses.[0003]In order to repair the slope and control the water and soil loss of the slope, the current engineering usually adopts the technology of transplanting and repairing of the guest soil and the three-dimensional vegetation net to repair the slope. However, the transplanting and repairing of the guest soil is not carried out after the vegetation on the exposed slope. Maintenance will lead to uneven growth of vegetation, complex three-dimensional vegetation net restor...
