Abstract

The invention belongs to the technical field of a fertilizer, and concretely relates to an attapulgite mixing fertilizer having slow release effect, the attapulgite mixing fertilizer is prepared by using attapulgite ore. The attapulgite can use own surface activity, adsorptivity, catalysis performance, filtering effect, ion exchange effect, complexation effect and electrostatic interaction, a soil pH value can be adjusted by two items, and attapulgite can provides appropriate growth environment for crops. The attapulgite can change physical and chemical properties of the soil, reduces soil unit weight, promotes formation of a soil gel state, enhances soil permeability, absorbs harmful heavy metals in the soil, and inhibits insect disease; beneficial elements in the soil can be converted through chelating effect, nutrition balance is reached, crops growth is cooperated, output is increased, and agricultural product quality is improved.

Description

A kind of Attapulgite mixed fertilizer with slow release effect
Technical field
The invention belongs to technical field of fertilizers, be specifically related to a kind of Attapulgite mixed fertilizer with slow release effect utilizing Attapulgite Clay Minerals to prepare.
Background technology
Along with the fast development of China's modern intensive agricultural, use inorganic fertilizer in a large number unreasonably for a long time, destroy agricultural land soil structure gradually, change the physico-chemical property of soil, cause soil compaction and degeneration, the effect of increasing production of chemical fertilizer is more and more not obvious, thus cause the yield and quality of farm crop to decline, xenobiotic pollutants can enter animal and human's body by the circulation of water body, air and food chain, thus the health of harm people and animals, cause cancer or chronic disease etc.
Features of Attapulgite Minerals is various places all over the world almost, and many attapulgite ore deposits point is verified on the ground such as China Gansu, Jiangsu, Anhui, and output is stared at tire with Jiangsu and ranked first.The attapulgite reserves now having verified Gansu, up to more than 1,000,000,000 tons, put more than 50% of global reserves.Although the resource reserve of China's attapulgite is very large, but it is more late due to what find, its development of exploitation level is lower, add that national nonmetalliferous ore processing industry basis is relatively weak, the attapulgite products that can produce compares also suitable lacking with other country, so that make the application of the great mineral reserve of this economic implications also be only limited to general filler, even export at an easy rate with the form of original soil, cause the waste of resource.Utilize attapulgite to produce fertilizer synergist, the Attapulgite resource that China Gansu province is abundant can be made full use of, also for development green ecological agricultural provides fertilizer guarantee.
Summary of the invention
The invention provides and a kind ofly can improve soil quality, with low cost, respond well, environmental friendliness, the Attapulgite mixed fertilizer that has wide range of applications.
The technical solution adopted for the present invention to solve the technical problems is:
There is an Attapulgite mixed fertilizer for slow release effect, comprise following preparation process:
A, crushing raw ore
Attapulgite Clay Minerals is broken, broken order number 30 order-60 order;
B, acidification
The vitriol oil adding massfraction 98% in water is mixed with the sulphuric acid soln of volumetric molar concentration 1 ~ 3mol/L, and add sulphuric acid soln in Attapulgite Clay Minerals broken in step, acidification makes attapulgite clay in 4 hours;
C, airing screening
Attapulgite clay after acidifying is carried out airing, and airing makes attapulgite clay water ratio be down to 15%, then pulverizes, and carries out screening and obtain attapulgite, and mesh size is 100-150 order;
D, to bake
Attapulgite after screening is sent into stoving oven and carries out roasting, maturing temperature controls at 300-360 DEG C, roasting time 45-120 minute;
E, fertilizer preparation
Mix by weight, diammonium phosphate or urea mix with attapulgite.
The vitriol oil adding massfraction 98% in described step B in water is mixed with the sulphuric acid soln of volumetric molar concentration 2mol/L.
In described step C, the attapulgite after screening is sent into stoving oven and carry out roasting, maturing temperature controls at 360 DEG C, roasting time 60 minutes;
Described attapulgite is sent into tablets press and is carried out granulation process, and particle diameter is 2.5 ~ 3.5 millimeters.
Application of phosphoric acid two ammonium or urea in described step e, diammonium phosphate amount of application 100-200 thousand grams/acre, urea amount of application 40-80 thousand grams/acre, attapulgite amount of application 100-150 thousand grams/acre.
Beneficial effect of the present invention is:
The present invention's Attapulgite (attapulgite) used has another name called polygorskite (palygorskite), refer to attapulgite be chief component a kind of have unique layer chain-like structure containing Shuifu County's magnesium silicate clay mineral, it is all quite similar with CNT (carbon nano-tube) on size, shape and structure construction, the brilliant diameter of rod only tens to tens nanometers, very fine and smooth, be natural nano nonmetallic mineral material.These mineral are earthy, compact mass, originate in sedimentogeneous rock and weathering crust, and color is in white, canescence, Steel Gray, greyish-green or weak tiffany light, and soil property is fine and smooth, and have oily soapy, light weight, property are crisp, and fracture is conchoidal, and water-absorbent is strong; Tool viscosity and plasticity-time wet, dry post shrinkage is little, and water soaking collapses loose, and suspension meets ionogen not flocculation sediment.It has the attribute of nano material, all quite similar with CNT (carbon nano-tube) on size, shape and structure construction, is the natural nano structure mineral material with nanochannel structure.Because they have very strong colloidal property, absorption property, rheological property, catalytic performance, and very large specific surface area and certain cation exchange property, be therefore widely used as sorbent material, support of the catalyst and carrier etc.In addition, attapulgite is also widely used in the numerous areas such as environment protection, high-tech agricultural, life and health guarantee.These mineral are rich in the various trace elements such as teleorganic iodine, selenium, iron, platinum, silicon, calcium, magnesium, potassium.Therefore, attapulgite is in the world except Chilean iodine nitre, the only solid mineral being rich in iodine of another example.The silicon content of attapulgite reaches more than 40%, it has colloidal property simultaneously, rheological property, catalytic performance, absorption property, cation exchange property, dispersing property and expansion character, can, by accelerating infiltration and the expansion of nutritive ingredient, the Nutrient Absorption needed for its farm crop be improved greatly.
Attapulgite can utilize self surfactivity, adsorptivity, catalytic, filteration, ion exchange, complexing action and electrostatic interaction, two the pH values regulating soil, for farm crop provide suitable growing environment.Attapulgite can also change the physics and chemistry natural disposition shape of soil, reduce the soil weight, impel the formation of soil gel state, strengthen the gas permeability of soil, harmful heavy metal in absorption soil, suppress disease and pest, the beneficial element in huge legendary turtle cooperation conversion soil is crossed in traffic, reaches nutritive equilibrium, coordinates crop growth, improve output, improve quality of agricultural product.
