Summary of the invention
The purpose of this invention is to provide a kind of saltings composite fertilizer special that contains the desulfurization waste, a kind of improvement in salinization arable land and fertilizer of salinization arable land crop growth of being used for.By this approach, make that flue gas desulfurization waste of fire coal obtains reasonable use in the production of synthetic ammonia, solve the recycling problem of desulfurization waste.
This saltings composite fertilizer special is formulated by weight proportion by following ingredients: A: urea soln B: monoammonium phosphate C: vitriolate of tartar D: flue gas desulfurization waste of fire coal E: differentiation coal F: wilkinite.The specific complex fertilizer formula: by 1000Kg, monoammonium phosphate: 208Kg breaks up coal: 50Kg urea: the 435Kg vitriolate of tartar: the 100Kg wilkinite: 157Kg flue gas desulfurization waste of fire coal: 50Kg.
In the above-mentioned raw materials with monoammonium phosphate as chemically acid fertilizer, with vitriolate of tartar as physiological acidic fertilizer, with flue gas desulfurization waste of fire coal and humatite weathered coal as the alkaline land improving active substance,, make as the nutrient carrier with inorganic mineral wilkinite and humatite weathered coal with urea soln whitewashing rotary drum prilling process technology.
The desulfurization waste has the function and the effect in improvement saltings, has the function of regulating soil pH value, the structure of improving the soil, improving plant recovery of nutrient, can provide micronutrient element in sulphur, calcium, the silicon etc. for farm crop simultaneously.Utilize the desulfurization waste to produce fertilizer dedicated to alkaline land, can turn waste into wealth, resource is fully used, environment improves and purify.By in composite fertilizer, adding the desulfurization waste, improve the ventilating permeable of salt affected soil, improve the salt affected soil fertility level.The saltings compound fertilizer special is by the reasonable raw material prescription and take advanced Technology, has following advantage and characteristics:
1, the recycling of waste: Ningxia autonomous region and neighbouring province Inner Mongolia Autonomous Region thereof have abundant weathered coal resource, utilize flue gas desulfurization waste of fire coal and depleted weathered coal resource to produce the fertilizer dedicated to alkaline land material, can turn waste into wealth, resource rationally be utilized, environment improves and purify.
2, organic-inorganic combines: the desulfurization waste has the function and the effect of improvement alkaline soil, its principle is that calcium sulfate contained in the desulfurization waste is with the sodium particle in the calcium particle displacement soil colloid, the sodium particle of replacing is with pouring water or rainwater is got rid of, thereby reduced salt affected soil pH value and basicity; The humatite weathered coal is rich in humic acid, can eliminate the toxic action of salt, fertilizing soil.Humic acid is a weak organic acid, can form a buffering system with salt, has the function of adjusting and stable soil pH value.Desulfurization waste and weathered coal compounding application can be got rid of saline and alkaline, can improve the soil effectively again physicochemical property, fertilizing soil all have improved effect for alkaline earth and solonchak, and the two compounding application is better than using the salt affected soil improved effect separately.
3, to the influence of Soil structure: the salt affected soil structure deteriorate, ventilating permeable is poor, physical property deterioration.The contained calcareous nutriment of desulfurization waste has vital role in soil structure improved addictive, breaking up humic acid contained in the coal simultaneously can increase the content of the soil organism, improve the soil water-reataining fertilizer-keeping ability, help the formation of soil aggregate, the two combination of weathered coal and desulfurization waste is used, for the structure of improving salt affected soil and ventilating permeable better effects if.
4, improve nutrient availability: the humatite weathered coal can promote the activity of soil microorganisms, improve the activity of soil plurality of enzymes and the validity of phosphorus element, can also increase the solvability of calcium sulfate in the soil solution in the desulfurization waste, promote the exchange of sodium particle in calcium particle and the alkaline soil, help crop nutrient absorbing utilizations such as phosphorus, sulphur, calcium.
