A revegetation method for tailings dams in the northern region includes the following steps: (A) slopes are cleaned up and leveled in order to eliminate potential geological hazards; (B) the surface layer of a tailings dam is covered by 10 to 15 centimeters of planting soil; (C) slurry-like plant-growing soil culture medium is sprinkled on the surface of the covering soil, so that a plant-growing substratum with a stable, excellent crumble structure is formed; (D) plant seeds with high stress resistance combined with artificial soil are chosen to be sowed on the surface of the plant-growing substratum, so that a seed layer which is about 2 centimeters in thickness is formed; (E) a management measure with a spray irrigation system and protective nets is adopted to maintain epigaeous seedlings at the late stage. The revegetation method has the advantages that the revegetation method can enhance the adaptability of plants to the complex adverse environment of a tailings pond, including stronger drought-resisting, saline-alkali tolerant, barren-tolerant and nutrient-obtaining capabilities, the method can be utilized to restore the ecology of the slopes of the tailings dam and build a steady vegetation layer, and also has the effects of stabilizing the slopes, conserving water and soil and inhibiting runoff and flying tailings sand.

The invention discloses a seashore saline land improver, a preparation method of the seashore saline land improver and a seashore saline land improvement method. The seashore saline land improver comprises the following components in parts by mass: 5-20 parts of industrial waste gypsum, 0.2-1 part of monosodium glutamate waste residue, 30-60 parts of plant waste ground and decomposed material, 0.01-1 part of anionic polyacrylamide and 5-15 parts of bacillus flora. The seashore saline land improver is applicable to seashore saline areas in both north and south China and can rapidly improve the saline land within 50-70 days, and the salinity of the saline land is reduced to a concentration suitable for plant growth. Moreover, the improver has excellent fertilizer maintenance and salinity reduction effects and can achieve the effects of improving the pore structure of soil and reducing the volume weight of soil.

The invention provides a novel slag soil conditioner and a preparation method thereof. The preparation method comprises the following steps: crushing and uniformly mixing slag and zeolite to obtain amixture a, uniformly mixing medical stone, diatomite, sodium polyacrylate, Devodol plant nutrient soil, an inorganic fertilizer and organic fertilizer to obtain a mixture b, wherein the adopted compound microbial agent is bacillus yersiniae, aspergillus oryzae, pseudomonas zhaodong and bacillus licheniformis, and mixing the mixture a, the mixture b and a microbial agent in a ratio of (5-7g): (4-6g): (2-3mL) to prepare the novel slag soil conditioner. The novel soil conditioner provided by the invention can effectively improve the properties of saline alkali soil, improve the structure and permeability of the saline alkali soil, reduce soil pollution, improve soil fertility, recycle waste resources, is simple to process, reduces investment, and can effectively meet the growth requirements of plants.

The invention discloses a metal epoxy protective paint which is prepared from the following raw materials in parts by weight: 40-45 parts of urethane acrylate, 30-42 parts of amino resin, 40-45 parts of E-12 epoxy resin, 6-8 parts of trimethylolpropane triacrylate, 1-2 parts of styrene, 2-3 parts of enclosed type isocyanate (TS280), 2-3 parts of ethylene glycol monobutyl ether, 3-4 parts of calcium naphthenate, 10-12 parts of titanium dioxide, 6-8 parts of kaolin, 2-3 parts of iron oxide red powder, 1-2 parts of copper powder, 2-3 parts of zinc powder, 4-5 parts of benzoin dimethyl ether, 9-12 parts of ethyl acetate and 3-4 parts of dispersing auxiliary. According to the dispersing auxiliary, the optical performance is improved, so that the paint is uniformly dispersed, and the stability of the paint is maintained. The metal epoxy protective paint has extremely strong corrosion resistance, rust resistance and saline-alkaline resistance, is high in hardness, resistant to scratch, simple in preparation process, overcomes the defects of the traditional epoxy paint and is especially suitable for back face protection of a metal plate.
