Abstract

The invention discloses a phosphogypsum-containing soil improvement biological organic-inorganic mixed fertilizer. The phosphogypsum-containing biological organic-inorganic mixed fertilizer comprisesthe following components in parts by weight: 40-55 parts of phosphogypsum; 5-12 parts of pine needles; 6 to 15 parts of eupatorium adenophorum; 5 to 14 parts of sticktight; 40 to 70 parts of green grass; 2-6 parts of raw material glucoamylase; 8 to 15 parts of sweet wormwood herb; 20 to 30 parts of oil cake; and 5-10 parts of quick lime; the raw materials are dried, ground into powder and then uniformly mixed, and the mixture is fermented for 7-15 days to obtain the phosphogypsum-containing biological organic fertilizer. According to the invention, artemisia apiacea and sticktight interact with each other to form compatibility; the invention has the advantages of effective inhibition of the activity of heavy metals in ardealite, elimination of the toxicity of ardealite, improvement of soilby using ardealite, increase of the utilization rate of ardealite, comprehensive nutrition, easiness in absorption by crops, low production cost, no industrial pollution, solving of the problem of soil hardening caused by chemical fertilizers, and accordance with the agricultural sustainable development road.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a soil-improving bio-organic-inorganic mixed fertilizer containing phosphorus gypsum and a preparation method thereof. Background technique [0002] Phosphogypsum is a solid waste from the production of phosphate fertilizer and phosphoric acid. It is a powdery material with almost no plasticity. The main component is CaS0 4 2H 2 0 and Na 2 SiF 6 , In addition, phosphogypsum also contains elements such as arsenic, silver, barium, cadmium, chromium, lead, mercury and selenium, as well as residual phosphoric acid, sulfuric acid and hydrofluoric acid, so phosphogypsum is acidic. Stacking phosphogypsum not only takes up a lot of land, but also causes environmental pollution. Therefore, it is necessary to find a reasonable way to use phosphogypsum to achieve sustainable development of the phosphate fertilizer industry and high utilization of phosphogypsum. ...
