Problems solved by technology

[0005] In fact, there is a "universal binding constraint" between soil particles. This constraint allows the soil to allow plant roots to grow inside it, and to retain water, fertilizer, and ventilation, while sand particles do not have such constraints. Therefore, conventional methods It is difficult to fundamentally solve the problem of sandy soil

Embodiment 1

[0045] see figure 1 , a kind of magnetic suction type sandy soil remediation method, comprises the following steps:

[0046] S1. Insert a hollow tube into the soil, then evenly inject a plurality of pre-embedded balls 1 into the soil, and then crush the dried fallen leaves to make pressed composite scales 2 for later use;

[0047] S2. After preparing the repair solution according to the formula, mix it with the pressed composite scale 2 in a mass ratio of 1:0.1-0.2, and then spray it on the soil, and pay attention to ignoring the hollow tube area;

[0048] S3. The pressed composite scale 2 penetrates into the soil with the restoration fluid and is close to the pre-embedded ball 1, and then triggers the bonding effect on the soil;

[0049] S4. After the soil is repaired to restore the cohesive force, the pre-embedded ball 1 is recovered from the hollow tube through the action of a magnetic field, and the hollow tube is taken out and covered with a layer of fallen leaves on the...

Abstract

The invention discloses a magnetic attraction type sandy soil remediation method, and belongs to the technical field of soil governing. According to the magnetic attraction type sandy soil remediation method, a plurality of embedded balls are evenly embedded into soil firstly, then composite scales are pressed in a wrapping mode through remediation liquid, and when the composite scales are pressed to permeate into the soil along with the remediation liquid, the composite scales approach the embedded balls, under the magnetic attraction effect of the pre-buried ball on the press-fit composite scales, the press-fit composite scales extrude the pre-buried ball through soil, meanwhile, moisture in the repairing liquid is also in contact with the pre-buried ball, and the pre-buried ball and the soil jointly trigger the action that the pre-buried ball releases auxiliary bonding fibers and heat; the heat is used for heating the press-fit composite scales to enable the press-fit composite scales to disintegrate and release the plant adhesive to act between the soil, meanwhile, the magnetic attraction effect of the embedded balls on the press-fit composite scales is enhanced, the soil, the plant adhesive and the auxiliary adhesive fibers are mixed at the moment, extrusion force is applied to a local area through the press-fit composite scales, and thus the bonding effect on the sandy soil is obviously improved.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a magnetic suction type sandy soil restoration method. 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 in arid, semi-ar...
