The invention discloses a soil-conditioning type
fertilizer. The
fertilizer is prepared from following raw materials in parts by weight: 32-36 of
rapeseed cake, 22-24 of
furfural residue, 20-24 of
gypsum, 19-23 of
lime, 4-6 of
vermiculite, 3-5 of
molybdenum tailings, 5-7 of
dolomite, 9-11 of diatomite, 7-10 of
anthracite, 4-5 of
calcium ammonium nitrate, 2-3 of
copper sulfate, 1-2 of
zinc sulfate, 1-2 of
ferrous sulfate, 1-3 of
manganese sulfate, 3-6 of a humate, 12-13 of a
soil conditioner and a proper amount of water. The
rapeseed cake, the
furfural residue, and other raw materials are adopted by the soil-conditioning type
fertilizer. The raw materials are convenient to take, low in cost and rich in
nutrition, and capable of improving the
soil structure. The
vermiculite has good cation exchange property and absorptivity, and is capable of conditioning the
soil structure, enhancing air permeability and
water retention of the soil, allowing the acid soil to change into neutral soil, and allowing slow release of the fertilizer in
crop growth media. In addition, the
vermiculite can provide self-containing K, Mg, Ca and Fe, and trace Mn, Cu, Zn, and other elements for crops. The
furfural residue can effectively restore the soil, and overcome
pollution of furfural residue
solid waste to the environment in the
soil restoration process. The furfural residue
solid waste is utilized reasonably, thus achieving
resource utilization of pollutants. The
molybdenum tailings, the
dolomite, the diatomite, the
anthracite, and other raw materials are added for supplement, thus fully utilizing resources, reducing the production investment and reducing
pollution caused by chemical fertilizers.
