Description
Technical field
The present invention is a kind of multifunction soil conditioning agent and preparation method thereof.Belong to soil adjusting, stable material.Being particularly related to a kind of is the multifunction soil conditioning agent that main raw material is made with the industrial residue.
Background technology
Land plant grows required moisture and nutritive ingredient almost all from soil.Therefore, the high-quality of agricultural-food, stable and high yields depend on good edatope.The soil physics structure is appended, caused to the influence of different regional climates, environment, the excessive discharging of three industrial wastes, chemical fertilizer unordered, the chemical property variation, nutritive ingredient imbalance, trace element lack, the deficiency of beneficial microbe colony, the intrusion of germ etc. all can be brought negative impact to edatope.
In the prior art, though developed the numerous soil conditioner of kind.But mostly function singleness, to the bad adaptability of different soils; The working conditions harshness, the improper use meeting causes secondary pollution; Cost an arm and a leg, increased the cost of agricultural-food; Facility investment is big, the manufacturing process complexity.
The discharging of industry phosphoric acid by wet process device waste residue-phosphogypsum causes very big pollution to physical environment and water body, also is the significant wastage of precious resources.Rational exploitation and utilization, extremely urgent.Someone is used as soil conditioner, but only is applicable to salt affected soil.The a large amount of flyash of discharged from coal-fired boiler of thermal power generation system and the operation of other heating systems, another hang-up that its development and use are environmental improvements.Also relevant for the patent application that utilizes flyash as soil conditioner, but it only is applicable to acid soil; With using after the vitriolization, performance makes moderate progress, but causes the raising of technology manufacturing step complexity and manufacturing cost.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art, is main raw material and provide a kind of with industrial residue-phosphogypsum and flyash, turns waste into wealth; Good to soil suitability, be applicable to various soil; Easy to use, all the components all can be accepted by soil; Have that fertilising getting fat, slowly-releasing fixed nitrogen, water conservation are protected soil, regulated soda acid concurrently, bacteriostatic and disease prevention, cheap ideal multifunction soil conditioning agent.
The present invention also aims to provide that a kind of low equipment investment, preparation technology are simple, the preparation method of the multifunction soil conditioning agent of the present invention of low cost of manufacture.
Purpose of the present invention can reach by following measure:
Multifunction soil conditioner of the present invention is characterized in that with the industrial residue being main raw material, comprises following feed composition (butt weight part):
Phosphogypsum 15-80
Flyash 5-60
Ground phosphate rock 2-40.
The main chemical compositions of phosphogypsum is CaSO
4.2H
2O, pH value 1-4.5.The element sulphur of sulfate radical form is that plant is easy to absorb, and this component enters soil has increased that it is calcareous, has reduced the alkalescence of soil; Improve the perviousness of soil simultaneously by the exchange of calcium ion and sodium ion, alleviated hardening that excessive use because of chemical fertilizer causes; Phosphogypsum uses with nitrogenous fertilizer can suppress the rate of nitrification of nitrifier to nitrogenous fertilizer, and nitrogen is slowly discharged, and plays the effect that improves fertilizer efficiency; Can also prevent and treat the bitter pit of apple, the diseases of agricultural plants such as dried worry of Chinese cabbage.
The flyash composition comprises SiO
2, AL
2O
3, Fe
2O
3, MgO, CaO etc., pH value 4.5-12.8.P, the K, Mg, Ca, B, Zn, Cu, S, the various nutrient elements such as Si, Mo that contain the plant-growth needs, and after going through the boiler furnace pyroprocessing, the vesicular structure of formation has distinctive surface adsorption performance.This component enters soil and plays improvement weight clay and soil building effect, improves the soil physics structure and improves the gentle water retention capacity in ground, holds concurrently and regulates the function of soil alkalescence, fluffy soil.
The contriver finds that acidic medium can excite the active mechanism of flyash, and its adsorption activity and flocculence are significantly strengthened, and the AL in the component, Si and Fe etc. all can strippings, form macromolecular compounds such as multiple coordination compound, complex compound, polymkeric substance.Almost whole components of flyash are all had every advantage and not a single disadvantage to improving the soil.
The present inventor introduces flyash and ground phosphate rock in the prescription of soil conditioner dexterously simultaneously, compound again ground phosphate rock.Make the acidity of phosphogypsum and the alkalescence of flyash obtain elimination simultaneously, the P element that ground phosphate rock is brought into enters soil for plant absorbing, and fluorine element is fixed in the soil, has reduced HF to atmospheric pollution, has successfully finished the present invention.All chemical ingredientss of multifunction soil conditioner of the present invention are all effectively utilized.
Purpose of the present invention can also reach by following measure:
Multifunction soil conditioner of the present invention is characterized in that comprising following feed composition (butt weight part):
Phosphogypsum 35-70
Flyash 7-35
Ground phosphate rock 7-35.
Multifunction soil conditioner of the present invention, the water content that it is characterized in that described phosphogypsum is less than 10%.
Multifunction soil conditioner of the present invention is characterized in that described flyash is from the flying dust of fire coal boiler fume through collecting after the dedusting, the waste residue that flue gas discharges, a kind of or its any two or more combinations the furnace bottom ash after desulfurization.
