Description
Technical field
The invention belongs to Saline-alkali Field Control technical field, be specifically related to a kind of fertilizer containing desulfurated plaster and preparation thereof
Method and application.
Background technology
Saline-alkali soil is solonchak and alkaline earth and various salinization, the general name of alkali-affected soil.Solonchak refers to soluble organic fraction in soil
Content reaches to a certain degree, it is possible to the g and D of plant is produced the great soil group substantially endangered.Alkaline earth refers in soil containing big
Amount commutativity ion, quantity reaches to endanger the degree of plant growing and growth, and makes the soil that soil property changes.
The salinization of soil of soil refers to owing in soil, a large amount of of salt basic ion accumulate, the process that soil types gradually changes to saline-alkali soil, its
Influence factor includes natural cause and anthropic factor.Easily there is the phenomenon that hardens in salt affected soil under normal circumstances, causes soil
Porosity diminishes, and the gas permeability of soil and water penetration are deteriorated, and badly influence the metabolism of Soil Microorganism, reduce the work of various enzyme
Property and carbon, the mineralization degree of nitrogen element, the conversion of soil with organic matter is slack-off, eventually results in soil the barrenst.Soil contains
The a large amount of salt ions having also can badly influence the normal physiological function of salt-soda soil plant, suppresses its g and D.It addition, with
The continuous aggravation of socioeconomic development and mankind's activity, salt-soda soil resource increasingly receives publicity, and irrational irrigation is made
Degree also results in Pedotransfer function aggravation.Second Committee International Sustainable Development conference is just pointed out, the following meeting serious threat world
Agricultural sustainable development is the salinization of soil in soil, desertification and the big problem of soil erosion 3.
Desulfurated plaster (English name desulfuration gypsum) is also known as flue gas desulfurization gypsum, sulfur Gypsum Fibrosum or FGD stone
Cream, main component is the same with the natural gypsum, for calcium sulphate dihydrate CaSO4·2H2O, content >=93%.Desulfurated plaster is FGD process
Side-product, FGD process is a technology using Calx-limestone to reclaim the sulfur dioxide in coal-fired or oily flue gas.Should
Technology is Calx-limestone to be ground make serosity, make after dedusting containing SO2Flue gas removed by slurry wash device
SO2.Lime slurry and SO2Reaction generates calcium sulfate and calcium sulfite, and calcium sulfite is oxidized changes into calcium sulfate, obtains industry
By-product gypsum, referred to as desulfurated plaster.
Gypsum Fibrosum powder is one of five big gel rubber materials, occupies an important position, be widely used in building, build in national economy
Numerous applications such as material, industry mould and art model, chemical industry and agricultural, food processing and medicine beauty treatment, are a kind of
Important industrial raw materials.Desulfurization gypsum powder is the different of physics from the differentiation of general Gypsum Fibrosum powder, in desulfurization gypsum powder
Possibly together with silicon dioxide, sodium oxide, calcium carbonate, calcium sulfite, limestone, calcium chloride, magnesium chloride etc..Compared with other Gypsum Fibrosum powder
Relatively, desulfurization gypsum powder has renewable, and granularity is little, stable components, and objectionable impurities content is few, purity high.Currently mainly
It is used for producing plasterboard together with the natural gypsum, is additionally widely used in terms of alkaline land improving.Its principle is to utilize
Ion exchange is theoretical, replaces the sodium ion in soil colloid with the calcium ion in desulfurated plaster.
Summary of the invention
Invention broadly provides a kind of fertilizer containing desulfurated plaster and preparation method and application, preparation organic
Fertilizer is adapted to the improvement in salt-soda soil, and desalination is quick, and treatment cost is low, and using effect is notable.Its technical scheme is as follows:
A kind of fertilizer containing desulfurated plaster, by weight percentage, it includes following parts by weight of component: desulfurated plaster
35-45 part, feces of livestock and poultry and hay leaf 20-30 part, peat 5-10 part, pyrite 1-5 part and flyash 1-5 part.
Preferably, described fertilizer also includes the acid-sludge of 5-10 weight portion.
Preferably, described fertilizer also includes the microbial bacterial agent of 1-3 weight portion.
Preferably, microbial bacterial agent is the mix bacterium agent of Glomus mosseae, Glomus etunicatum and bacillus subtilis.
Preferably, the bacterium solution addition of Glomus mosseae, Glomus etunicatum and bacillus subtilis is 2:1:1.
Preferably, by weight percentage, described fertilizer includes following parts by weight of component: desulfurated plaster 38-42 part, poultry
Poultry manure and hay leaf 25-27 part, 8 parts of peat, pyrite 2 parts and 3 parts of flyash, acid-sludge 7 parts, microbial bacterial agent 2 parts.
Preferably, the effective ingredient of desulfurated plaster is CaSO4·2H2O, CaSO4·2H2Content >=93% of O.
The preparation method of a kind of fertilizer containing desulfurated plaster, comprises the following steps:
(1) desulfurated plaster, peat, pyrite, flyash are carried out air-drying pulverizing, and process of sieving；
(2) weigh feces of livestock and poultry and the hay leaf of formula ratio, add acid-sludge and the microbial bacterial agent of formula ratio, carry out close
Seal ferment 15-20 days, turned over every 3-5 days and pushes away once, generated the mixture of corruption；
(3) adding the desulfurated plaster after pulverizing, peat, pyrite, flyash in the mixture of corruption, stirring mixing is all
Even, obtain the fertilizer containing desulfurated plaster.
The application of a kind of fertilizer containing desulfurated plaster, concrete is that the described fertilizer containing desulfurated plaster is suitable for
In the improvement to the saline-alkali soil that pH is 10-13.
Use above-mentioned fertilizer containing desulfurated plaster and preparation method and application, the invention have the advantages that
(1) flyash is the main garbage in thermal power plant, and annual China flyash annual emissions has surpassed hundred million, and produces
Amount increases year by year.Local environment protection is brought the biggest pressure by the bulk deposition of flyash, the most also gives the life of people and moves
The aspects such as the existence of plant, growth cause serious harm.And containing abundant weight, boron, sulfur, zinc, copper, calcium, magnesium, ferrum in flyash
Deng trace element, and quality is loose the bigger space of existence, at the regulation soil moisture and pH value, increases and supplements soil nutrient
Composition aspect effect is unique；
(2) mix bacterium agent in the present invention can increase vegetation to Na+Absorbtivity so that it is be gathered under ground portion, press down
Salt manufacturing divides the transport to top, reduces relative amount, improves the ionic equilibrium in plant body, alleviate the murder by poisoning of salt ion, mixing
The infection ability of microbial inoculum and promotion host plant growth aspect will be more preferable than inoculation single culture effect.
