Embodiment
Embodiment of the present invention is described in detail below in conjunction with embodiment, but those skilled in the art will
Understand, the following example is merely to illustrate the present invention, and is not construed as limiting the scope of the present invention.It is unreceipted specific in embodiment
Condition person, the condition advised according to normal condition or manufacturer is carried out.Agents useful for same or the unreceipted production firm person of instrument, be
The conventional products that can be obtained by commercially available purchase.
Present embodiment provides a kind of soil-repairing agent in salt-soda soil, the raw materials by weight portion meter bag of soil-repairing agent
Include：
The parts by weight of flue gas desulfurization waste of fire coal 12~23,5~9 parts of mix bacterium agent, 6~9 parts of porous carrier, mixing are planted
8~15 parts of thing powder, 5~10 parts of oil cake, 8~15 parts of humic acid.
Further, count by weight, flue gas desulfurization waste of fire coal is 15~20 parts by weight, mix bacterium agent 6~8
Part, 7~8 parts of porous carrier, 10~12 parts of mixed plant powder, 6~9 parts of oil cake, 10~12 parts of humic acid.
Further, mix bacterium agent is made by following methods：
Using the bacterium source with soil salt degradation capability as raw material, by the soil, carbon source, nitrogen source and the phosphorus that add salt-soda soil
Source carries out acclimation.
The source of bacterium source can have multiple choices, can be the pure culture or microbial bacteria of microorganism fungus kind
The bacterium solution with fluid nutrient medium formation is planted, the mixture of microorganism fungus kind and soil is can also be.Microorganism fungus kind can pass through
The methods such as artificial enrichment, domestication, genetic engineering transformation, or obtained by buying；In the present invention, select from salt-soda soil
It is enriched with activated sludge and tames flora, is the mixture of thalline and mud.
It should be noted that flora is by adding the soil in salt-soda soil, and gradually steps up the salinity in alkaline land soil, make
Flora has the ability of enduring high-concentration salinity, i.e., enduring high-concentration salinity and the salinity in soil can be degraded
Flora composite demand.That is, the present invention it is signified there is soil salt degradation capability do not imply that specific Pseudomonas
Or strain, as long as the combination for possessing the single culture or multi-cultur es of soil salt degradation capability meets the requirements.Through screening
Afterwards, the flora of gained can also possess very strong bioactivity in the heavy saline that pH value is more than 10.
Selectable, carbon source includes sodium acetate and the mixture of glucose formation, and nitrogen source includes ammonium chloride, and phosphorus source includes phosphorus
Sour hydrogen dipotassium and potassium dihydrogen phosphate；The mass ratio of carbon source, nitrogen source and phosphorus source is 100~120：5~7：1~1.5.
Carbon source can make mushroom direct using the use of sodium acetate and the mixture, especially glucose of glucose formation
Utilize；The mass ratio of carbon source, nitrogen source and phosphorus source is 100~120：5~7：1~1.5, it is ensured that carbon source, nitrogen source and phosphorus source have one
Rational ratio, it is ensured that the basic growth of mushroom, is unlikely to waste, causes the concentration of nutrient solution unbalance, influence the life of mushroom again
It is long.Phosphorus source includes dipotassium hydrogen phosphate and potassium dihydrogen phosphate simultaneously, and phosphorus can be both used as using dipotassium hydrogen phosphate and potassium dihydrogen phosphate
Source, moreover it is possible to used as buffer solution, can guarantee that the stabilization of the pH value of nutrient solution, be conducive to the growing environment of mushroom stable.
Further, flue gas desulfurization waste of fire coal is prepared by Limestone-gypsum Wet Flue Gas Desulfurization Process technique.Using this
The technique of wet desulphurization, is conducive to obtaining the more excellent flue gas desulfurization waste of fire coal of performance.Stone in flue gas desulfurization waste of fire coal
Cream content is 80~85wt%；Water content is not higher than 12%.The main chemical compositions of gypsum are CaSO4, it can be with salt-soda soil
Sodium salt (sodium carbonate, sodium acid carbonate) reaction in soil, generates Na2SO4, calcium ion replacement sodium ion after, on the one hand can be formed
Calcium colloid and organo-mineral colloidal complex, and then soil granular structure is changed, improve the permeability of soil；On the other hand can
Surface soil alkalinity is reduced, so as to eliminate murder by poisoning of the sodium ion to crop.
In preferred embodiments of the present invention, oil cake include castor-oil plant oil cake, vegetable seed oil cake, cottonseed oil slag, peanut oil cake and
One or more in flax oil cake.In the present invention, oil cake is residual after being deoiled with the more seed of oil composition through squeezing
The class organic fertilizer that slag is made according to a conventional method.The oil-containing of the seed of this five kinds of crops of castor-oil plant, vegetable seed, cottonseed, peanut and flax
Amount is high, while also being liked deeply by consumers in general as the vegetable oil obtained by this five kinds of seed squeezings, therefore, using this five kinds of seeds
The oil cake being processed into, oil content is more compared with other seeds, and yield is big, cheap.
Optionally, porous carrier includes any one of activated carbon, diatomite, bentonite and kaolin.Activated carbon,
These four materials of diatomite, bentonite and kaolin are respectively provided with cellular structure, and other groups in raw material can be made as carrier
Divide and be embedded in hole, slow down its rate of release, and then cause the soil-repairing agent that there is slow-release function, can be long-acting to salt
Alkali soil repaired.
Optionally, mixed plant powder includes maize pulp, licorice powder and asarum powder, maize pulp, licorice powder and asarum powder
Mass ratio is 2~5：1：1.Maize pulp is as vegetable ingredients, and yield is high, cheap and nutritive value is abundant, can be mixed
Close microbial inoculum and nutrient is provided.Radix glycyrrhizae and asarum are conventional Chinese herbal medicine, and the addition of both can be effectively improved alkaline land soil
PH value, reduce soil basicity.
The soil-repairing agent in this salt-soda soil, using flue gas desulfurization waste of fire coal and porous carrier, increase soil
Porosity and soil nutrient；By the addition of mix bacterium agent, increase the resistance and biological activity of Soil Microorganism；Together
When, oil cake further increases the nutritional ingredient in the soil-repairing agent with humic acid, makes the soil in salt-soda soil after improved reparation
Earth condition is more suitable for the growth of plant.The soil-repairing agent in this salt-soda soil, can effectively improve alkaline land soil
Physicochemical character, reduces the pH value of soil, reduces the content of soluble-salt in soil, and reduce the basicity of soil.
