Description
Technical field
The invention belongs to agricultural fertilizer material technical field, specifically, it is related to and a kind of is prepared using thermal power plant's discarded object
Sandy alkaline land improving fertilizer and preparation method thereof.
Background technology
More liquid since sand particle is loose, particles' interaction power is weaker, in waterpower, gravity, wind-force
It is easy to be destroyed land resource and fertility under acting on etc. external force, causes soil surface to be etched and moisture stream
Lose.Along with salinization and alkalization is more and more heavy, soil nutrient is barren, greatly constrains the planting industry production in sand area
Power level and revegetation ability.Therefore, improve sand crumb structure, improve containing for sand water stability performance
Amount, increases soil fertility, saline and alkaline is reduced, just into the research emphasis in the sandy salt-soda soil of improvement.
Power industry is coal-fired rich and influential family, the SO that coal-burning power plant is discharged every year2Account for the 50% of national total release, wet type stone
Lime stone-gypsum is the fume desulphurization method that thermal power plant is most widely used, this also have led to desulfurated plaster and flyash into
For two big solid waste of power plant, desulfurated plaster can effectively improve salt affected soil, and the sodium ion and gypsum in soil are molten
The calcium ion-exchanged produced is solved, supplement calcium ion can eliminate toxic action of the carbonate to plant, reduce the basicity of soil, adjust
The pH value of soil is saved, the dispersiveness of soil sticking grain is improved, soil water permeability is improved, while is also given birth in desulfurated plaster containing plant
The mineral elements such as long necessary sulphur, silicon, useful crop plants growth.The mineral element that flyash contains because of it, it has been reported that Japanese
Fertilizer is made into be applied.

Preferably, the plant haulm particle includes sawdust, stalk particle, powdered rice hulls, peanut shell powder.
The method that sandy alkaline land improving fertilizer is prepared using thermal power plant's discarded object, is comprised the following steps：
A. it is 20~30 by weight:10~14:4~6:3~5:3~5 prepare desulfurated plaster, flyash, sulfomethylated lignin
(inorganic fertilizer is that weight ratio is 2~4 for sour sodium, Lauxite, inorganic fertilizer:1~3:0.5~1 urea, Diammonium phosphate (DAP) and chlorination
Potassium), and be added to successively and crush and mix in pulverizer, wherein the urea in inorganic fertilizer and ammonium phosphate are dissolved in corresponding weight
Water in saturated aqueous solution is made, the mixture being added in above-mentioned pulverizer is sufficiently mixed；
B. it is 11~15 by weight:18~22:16~20 prepare municipal sludge, fulvic acid and straw
Grain, compost 15 days under field conditions (factors) after being mixed, during which every turning in 3 days once；Dried after the completion of compost；
C. as needed for each bacterium (bacillus subtilis, nitrogen-fixing bacteria, thermophilic salt basophilic bacterium, gel-shaped bacillus, Cong Zhi
VA Mycorrhizal Fungi and aspergillus) corresponding culture medium is prepared, and condition of culture is set, cultivate and each microbial bacterial agent is made, or purchase
Existing commodity；Mixing for standby use in proportion；
D. the pulverizer being added to the product in step b and weight ratio for product in 0.5~1.5 step c in step a
It is middle to crush and be sufficiently mixed；
E. obtained product in step d is delivered to comminutor to be granulated, then drying and moulding, up to improving fertilizer.
Preferably, comminutor is made for SET type double-screw extruding pelletizing machines or SES type Single screw extrusions in the step e
Grain machine.
Preferably, the diameter of the granulation in the step e is between 1.0~1.5mm.
By adopting the above-described technical solution, beneficial effects of the present invention are as follows：
1) sodium lignin sulfonate is a kind of natural polymers, has very strong dispersiveness, sand prevention, sand-consolidating agent and soil
Earth modifying agent；Lauxite can improve soil physical property, strengthen the water conservation soil conservation ability of soil, and have to fertilizer and inhale
Attached and release action, has an impact edaphon and enzymatic activity.
2) the suitable chemical fertilizer of addition can improve the fertility in soil rapidly, be grown beneficial to the rapid appreciation of plant, windproof
Fix the sand, water-retaining effect.
3) organic matter decomposition is fast, accumulative fewer in salinization of soil sand, thus causes soil fertilizer poor,
Various nutrients are all poorer, the nutrient energy formed by fulvic acid, straw, city compost sludge through microorganism decomposition
Rapid and lasting is supplied to soil nutrient, and reduces soil pH by producing the metal ion in acid, degraded or conversion soil
Value, changes soil texture, has protected plant nutrient equilibrium, supplement crop nutrition content, promote root system development, so as to improve crops
Yield, reduces farmland cost, achievees the purpose that to increase farmers' income.
4) bacillus subtilis in micro organism powder, nitrogen-fixing bacteria, thermophilic salt basophilic bacterium, gel-shaped bacillus, clump branch bacterium
Root fungus and aspergillus, nitrogen-fixing bacteria and arbuscular mycorrhizal fungus can itself fixed nitrogen or with plant cooperated fixed nitrogen；Thermophilic salt basophilic bacterium conversion is certainly
Metal ion supply plant in right boundary utilizes；Bacillus and aspergillus are mainly used for organic matter of degrading, and cooperate with increase plant
Resistance.
5) desulfurated plaster can effectively improve salt affected soil, and the sodium ion in soil is handed over the calcium ion that gypsum dissolution produces
Change, supplement calcium ion can eliminate toxic action of the carbonate to plant, reduce the basicity of soil, adjust the pH value of soil, carry
The dispersiveness of high soil sticking grain, makes soil water permeability improve, while also containing the necessary sulphur of plant growth, silicon etc. in desulfurated plaster
Mineral element, useful crop plants growth；Activated carbon can improve the structure of soil, and inhale because with flourishing gap structure
Unnecessary salt basic ion and pollutant in attached soil；The main oxides of flyash form:SiO2、Al2O3、FeO、Fe2O3、
CaO、TiO2、MgO、 K2O、Na2O、SO3、MnO2Deng in addition with P2O5Deng content of mineral substances enriches, and can effectively provide
Mineral matter element, and the unburned carbon granule in flyash is loose porous, can effectively improve the structure of alkaline land soil.
Therefore, this sandy alkaline land improving fertilizer can effectively improve the soil texture in sandy salt-soda soil, reduce saline and alkaline, drop
Sandy content in low soil, improve nutrient composition content in soil, improve soil density, coordinates plant culture, can persistently have
The sandy salt-soda soil of improvement of effect.
