Description
Technical field
The invention belongs to technical field of land improvement, specifically, are related to a kind of sandy salt-soda soil and are applicable in fertilizer and its prepare
Method.
Background technology
More liquid since sand particle is loose, particles' interaction power is weaker, in waterpower, gravity, wind-force
Etc. external force effect under be easy to be destroyed land resource and fertility, soil surface is caused to be etched and moisture stream
It loses.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.
The content of the invention
It is an object of the present invention to provide a kind of sandy salt-soda soils to be applicable in fertilizer；Effectively improve sandy salt-soda soil soil texture,
Sandy content in saline and alkaline, low soil is reduced, nutrient composition content in soil is improved, improves soil density, cooperation plant is planted
Training, persistently can effectively improve sandy salt-soda soil.
Another object of the present invention is to provide the preparation method that a kind of sandy salt-soda soil is applicable in fertilizer.
Technical solution of the present invention is as follows：
A kind of sandy salt-soda soil is applicable in fertilizer, is 20~30 including weight ratio:20~30:12~16:18~22:4~8:2
~4:2~4:1~3:0.5~1.5:0.5~1.5 attapulgite clay, flyash, humic acid, straw, urban life rubbish
Rubbish sludge, bentonite, polyacrylamide, carboxymethyl cellulose, hydroxyethyl starch and microbial germ powder.
Preferably, the attapulgite clay, flyash, humic acid, straw, domestic waste sludge, swelling
Soil, polyacrylamide, carboxymethyl cellulose, the weight ratio of hydroxyethyl starch and microbial germ powder are 25:25:14:20:6:3:3:
2:1:1。
Preferably, the microbial germ powder includes thermophilic salt alkalophilic bacillus, gel-shaped bacillus, arbuscular mycorrhizal fungus and song
It is mould.
Preferably, thermophilic salt alkalophilic bacillus, gel-shaped bacillus, arbuscular mycorrhizal fungus and aspergillus in the microbial germ powder
Content be respectively 0.5 × 109~1.5 × 109CFU、1.0×109~5.0 × 109CFU、5.0 ×109~15 × 109CFU and
5.0×109~15 × 109CFU。
Preferably, the straw includes one or more of corn, sorghum, cotton, wheat and paddy stalk.
A kind of sandy salt-soda soil is applicable in the preparation method of fertilizer, comprises the following steps：
A. weight ratio is 20~30:20~30:2~4 ratios pulverize and sieve attapulgite clay, flyash and bentonite,
It is spare；
B. object stalk crushes, and is 12~16 by weight:18~22:4~8 by humic acid, straw (corn, sorghum,
Cotton, wheat and paddy stalk) and domestic waste sludge it is admixed together, compost 15 days, during which every under field conditions (factors)
Every turning in 3 days once；It is dried after the completion of compost；
C. prepared as needed for each bacterium (thermophilic salt alkalophilic bacillus, gel-shaped bacillus, arbuscular mycorrhizal fungus and aspergillus)
Corresponding culture medium, and condition of culture is set, cultivate and each microbial bacterial agent is made or buys existing commodity；In proportion
Mixing for standby use；
D. product obtained in above-mentioned steps a, b and c is placed in pulverizer, addition weight ratio is 2~4:1~3:0.5
~1.5 polyacrylamide, carboxymethyl cellulose and hydroxyethyl starch is fully crushed and mixed；The wherein products weight of step c
Than for 0.5~1.5；
E. product obtained in step d is delivered to comminutor to be granulated, then drying and moulding is to get applicable 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) soil property of attapulgite clay is fine and smooth, there is oily soapy, light, property is crisp, and water imbibition is strong.Have when wet sticky and plastic
Property, dry after-contraction is small, less aobvious crackle, and water impregnates disintegration.Suspension meets dielectric not flocculation sediment, improves soil texture
Do not pollute surrounding enviroment and underground water again simultaneously, moreover it is possible to saline-alkali soil is neutralized, and plays good improved effect, it is quick, once
Property apply after be benefited all the life；Flyash can improve water-retaining quantity among field of soil, reduce saturated hydraulic conductivity in soil, while increase soil
Available water.
2) sand inter-granular porosity is big, quality is loose, permeability is good, and poor water retention property, water storage power are weak, not drought-enduring, and
Bentonitic water absorption rate is up to more than 100%, and volume energy increases 10~30 times with the moisture absorbed, can be in being manured into soil
Increase the quantity of soil agreegate, reduce the soil weight, increase soil porosity, both improved the water retention property of soil, reduce water
It is oozed under point, saves irrigation water, reduce watering man-hour, extend interval of pouring water, and secure the grains of sand, prevent the grains of sand from flowing, reduced
Soil erosion, and can implicit water source, can fully absorb the precipitation of autumn and winter after being applied in the autumn of the previous year.
3) the effects that carboxymethyl cellulose is known as thickening, film forming, gluing, water tariff collection, colloid protection, emulsification and suspends；It is poly-
Acrylamide is important water-soluble polymer, and has both flocculability, thickening property, endurance of cutting, the drop treasured such as resistive, dispersed
Your performance；Hydroxyethyl starch is used as soil stabilizer, usually conserves water and soil and drought-relief, waterlogging-preventing using to do tackifier.
4) organic matter decomposition is fast, accumulative fewer in salinization of soil sand, thus causes soil fertilizer poor,
Various nutrients are all poorer, the nutrition member formed by humic acid, straw, domestic waste sludge through microorganism decomposition
Element simultaneously lasting rapidly can be supplied to soil nutrient, and reduce soil by producing the metal ion in acid, degradation or conversion soil
Earth pH value changes soil texture, has protected plant nutrient equilibrium, and supplement crop nutrition content promotes root system development, so as to improve farming
The yield of object reduces farmland cost, achievees the purpose that increase farmers' income.
5) bentonite is had good repair for some by heavy metal (such as mercury, lead etc.) contaminated soil, it
Ion-exchange performance is fixed up the heavy metal in soil, i.e., heavy metal is passivated, and reduces its biological effectiveness, to subtract
Few absorption of the plant to heavy metal, so as to improve the quality of agricultural product.
6) thermophilic salt alkalophilic bacillus can survive under high alkali environment with high salt in microbial bacteria；Gel-shaped bacillus has activation
The ability of potassium in silicate mineral, moreover it is possible to utilize phosphorus element in apatite and fixed air nitrogen；Arbuscular mycorrhizal fungus energy and plant
It forms mycorhiza and carries out fixed nitrogen；The organic matter that aspergillus help is degraded in soil.
Therefore, this sandy salt-soda soil is applicable in fertilizer and can effectively improve the soil texture in sandy salt-soda soil, reduce saline and alkaline, drop
Nutrient composition content, raising soil density, cooperation plant culture can persistently have in sandy content, raising soil in low soil
The sandy salt-soda soil of improvement of effect.
