In summary, in this embodiment, according to the biological soil for mine vegetation restoration and the preparation method thereof in this embodiment, starch plastics are provided as a base material, and firstly, starch plastics are provided as a base material, so that actual soil conditions of a mine surface layer are considered, and vegetation coverage is lacking, which leads to that surface layer soil is extremely easy to be eroded by rainwater and wind, the biological soil for restoration can be used for regional separation of soil by virtue of the starch plastics to manufacture a sandwich net 9 and a consolidation frame 1, and the sandwich net 9 is used for fastening the soil material, so that erosion and scouring resistance of the soil material is improved, and further, the starch plastics are provided as a base material, so that not only can the effect of bonding all components be achieved, but also the starch plastics can degrade themselves, and meanwhile, energy substances are provided for microbial activities in the soil of regions; the consolidation frames 1 are made of the same material by means of the arrangement of the clamping columns 4 and the clamping grooves 3, are mutually clamped when stacked and arranged, and meanwhile, the consolidation columns 2 in the middle are pressed at one corner of the four consolidation frames 1 through the single-point position, so that the overall resistance can be enhanced, the cotton net bags 7 wrap the matrix body 10, and the clamping is completed by means of the supporting plates 8 and the cortex plates 6, so that loss of regional soil and nutrient components in the regional soil is avoided; the veneer sheet 6 is composed of wood dust, dead leaf powder and humus, creates a microorganism activity space, and is combined with sludge in the matrix 10 to construct an ecological system in the area of the consolidation frame 1; the water-retaining agent is a functional polymer material with extremely strong water absorption capacity; the fertilizer is nontoxic and harmless, can repeatedly release and absorb water, can absorb fertilizer and pesticide, and can slowly release the fertilizer, thereby improving fertilizer efficiency and pesticide effect; the regulator can provide fertilizer and necessary trace elements for vegetation growth, and the biological flocculant can enable solid suspended particles which are not easy to degrade in the liquid to be condensed and precipitated as special high polymer metabolites; the chelating agent reacts and precipitates heavy metal ions existing in the mountain area, so that the heavy metal ions are prevented from entering the water body or vegetation; through setting up heating and melting process and mould and wire drawing processing for starch plastics can be through a plurality of products of output, and possess certain intensity, and in the preparation of cortex board 6, carry out the low temperature and deposit, can avoid its inside microbiota to suffer destruction, and mud memory separately handles, utilizes fermented sludge to guarantee the stability of base member environment promptly, avoids its metamorphism, and dry-made mud then can lock most microbiological state to reduce its activity, thereby be favorable to preserving transportation and ground to arrange for a long time.
The above is merely a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art will be able to apply equivalents and modifications according to the technical solution and the concept of the present invention within the scope of the present invention disclosed in the present invention.
