Description
Technical Field
The invention relates to the field of environmental protection methods, in particular to a spray for promoting soil skinning and a preparation method and application thereof.
Background
Soil crust is divided into biological crust and physical crust. Soil bio-crusts are complex aggregates of moss, algae, fungi and bacteria and many non-vascular plant components common in landscapes combined with very thin layers of soil beneath them. The physical soil crust is a structural crust formed by physical changes of soil aggregates caused by tamping surface soil by rainfall. Physical soil crusting can obviously reduce water infiltration, increase runoff to inhibit the exchange of substances and energy between soil and atmosphere, and influence the growth of crops. The crust soil has formed a crust with a very unstable structure.
The skinning force and the skinning principle of the soil biological skinning are different from those of physical skinning, the skinning degree is relatively low, and the tightness in the skinning process is not high, so that the infiltration of moisture cannot be excessively influenced, and the effects of wind prevention, sand fixation and soil erosion prevention can be achieved.
However, biological crust is affected by a plurality of environmental factors together and cannot be formed simply, so that soil crust cannot be formed in most wind power and hydraulic power erosion staggered areas, and therefore, the soil structure is frequently damaged due to wind power erosion and hydraulic power scouring all the year round.

Compared with the prior art, the invention has the beneficial effects that:
1. the spraying agent A is firstly sprayed, after the spraying agent A is sprayed on the surface layer of soil, the spraying agent A starts to grow by utilizing external nutrient substances, wherein algae filament bodies of algae and a large amount of hyphae of ascomycetes are mutually interpenetrated to form a net-shaped connected structure, and are simultaneously connected with a fiber structure of nano-scale attapulgite to form a net-shaped structure together so as to promote the skinning of the soil surface, and loose soil grains are bonded with the whole net-shaped structure by organic gel and polysaccharide secreted by the algae so as to form an anti-corrosion layer, so that the stability and the anti-weathering capability of the soil surface are effectively enhanced, and the soil surface is softened when encountering moisture, so that the moisture absorption can be promoted.
The algae is accessed after the spray A is sprayed, so that the formed algae crusts are facilitated, the water-stable soil aggregate and organic matter content in the crusts are greatly increased in the development process, the moisture absorption of the soil is greatly improved, the water content of the soil is favorably maintained, the volatilization rate of the soil moisture is favorably reduced, the stability of the floating soil is finally improved, the permeability can be further ensured in the process of realizing wind erosion resistance and water scouring resistance, and the nutrients of the surface soil are improved.
2. According to the invention, the spray agent A is sprayed firstly, so that the fulvic acid and the uterine acid in the spray agent A form negatively charged organic limbs on the surface layer of soil, the organic limbs are in a sol state and are dispersed in a spraying mode, after the spray agent B is sprayed, the electrolyte salt in the spray agent B is dissolved in water to form an electrolyte solution, the electrolyte enables colloids on the surface layer of the soil to be coagulated to form gel, soil particles can be cemented together in the coagulation process to form a good structure body, and the soil surface layer skinning is promoted.
3. The spray B also comprises a nutrient solution, and the nutrient solution can supply nutrient substances for algae and ascomycetes sprayed in the spray A firstly, so that the growth of the algae and the ascomycetes is promoted, and the skinning effect is enhanced.
4. According to the invention, the spray agent A and the spray agent B are sprayed in sequence, so that the spray agent A and the spray agent B interact with each other, the soil surface crusting is promoted, the permeability of the soil can be ensured while wind erosion and hydraulic erosion are prevented, the nutrients of the surface soil are improved, and the method has profound practical significance.

As can be seen from the above table, the spraying agent for promoting soil skinning can increase the soil viscosity, increase the soil compressive strength and greatly improve the water retention of the soil.
It should be noted that the electrolyte salt in the present invention is a salt that can be dissolved in water to form an electrolyte solution.
While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
