Problems solved by technology

[0004] The existing method of controlling soil desertification mainly adopts afforestation, but this method requires a lot of investment, slow results, long cycle, and cannot directly prevent soil moisture from evaporating and losing, and has little effect; some areas use spray film, liquid film, etc. methods, but they can only play a role in a short period of time, and cannot fundamentally control soil desertification

Embodiment 1

[0042] see figure 1 , a desertification soil air flushing control method, comprising the following steps:

[0043] S1. Weigh the corresponding raw materials according to the formula to prepare the restoration solution, and divide it into two identical parts, make pre-embedded balls 1 of different sizes in advance, and then mix with one part and spray on the soil surface;

[0044] S2. When the repair fluid and the pre-embedded ball 1 penetrate into the soil, start the vibrator to vibrate the soil at high frequency, accelerate the penetration and at the same time assist the pre-embedded ball 1 of different sizes to vertically distribute in the soil along the upper and lower sides;

[0045] S3. After the vibration for 10-20min is over, take the remaining repair solution and mix it with tartaric acid with a mass ratio of 0.01-0.05 and spray it on the soil surface;

[0046] S4. The restoration fluid passes through the pre-embedded balls 1 distributed in the soil sequentially along...

Abstract

The invention discloses an air impact type treatment method for desertified soil, and belongs to the technical field of soil treatment. According to the method, the characteristics of desertified soil are utilized, embedded balls permeate into the soil on the basis of the mode that the embedded balls are wrapped with a remediation liquid, the embedded balls of different sizes are vertically distributed in the soil in a mode that bigger balls are placed at the top and smaller bags are placed at the bottom under the effect of external vibration, the remediation liquid doped with tartaric acid is used to dissolve isolation materials on the surfaces of the embedded balls, so that the air impact action of the embedded balls is triggered, viscous media are diffused and released to all areas of the soil, the desertified soil is bonded, effective sand-fixing and water-retaining effects on the desertified soil can be achieved based on the hydrophilic characteristic of the soil, and meanwhile, the remediation effect of the remediation liquid is employed, so that the reason of soil desertification is fundamentally solved, and the desertified soil can be efficiently treated within a short time.

Description

technical field [0001] The invention relates to the technical field of soil treatment, and more specifically, relates to an air flushing treatment method for desertified soil. Background technique [0002] At present, climate warming and precipitation reduction have exacerbated the aridification of climate and soil in Northwest China. This reduces the vegetation coverage in this area, and the soil structure becomes looser, which accelerates the desertification of the land. In addition, the warming of the climate and the continuous drought of the large-scale climate have seriously affected various water resources (glaciers, lakes, rivers, etc.), causing glaciers to retreat, rivers to reduce or stop flowing, lakes to shrink, and groundwater levels to drop. A large area of ​​vegetation died due to lack of water, which lost the function of protecting the surface soil and accelerated the speed of soil desertification. [0003] Soil desertification is defined as land degradation...
