Description
Technical field
The present invention relates to slow release fertilizer technical field, more particularly, to a kind of efficiently delaying for salt soil Semen Coicis Efficient Cultivation
Release fertilizer and preparation method thereof.
Background technology
Chemical fertilizer, as important agriculture data, plays the important and pivotal role in terms of improving grain yield, although I
State's fertilizer amount total amount is big, but fertilizer utilization efficiency is far below World Developed Countries level.Nitrogenous fertilizer profit in the traditional fertilizer fertilising of China
It is 30%～35%, phosphate fertilizer this season utilization rate 8%～20%, potassium utilization rate about 50% with rate, most of nutrition divides with seepage and steaming
Send out and run off in air and subsoil water, not only waste serious, and the environmental pollutions such as soil, air, subsoil water can be caused.Cause
This, be modified to fertilizer, and improving fertilizer efficiency is to reduce fertilizer to use, the effective way increased operation rate.For example current slow-release or control-release fertilizer
Exactly improve one of effective measures of chemical fertilizer utilization ratio, slow-release or control-release fertilizer can efficiently control the release of nutrient, extends fertilizer efficiency period, expires
Utilization rate that the whole period of duration of sufficient crop to the needs of fertilizer nutrient, can improve fertilizer to greatest extent, reduce the wasting of resources and
Environmental pollution, to promoting agriculture and forestry volume increase, increasing peasant income, agriculture and forestry sustainable development important role, is 21 century fertilizer
The important development direction of industry.
Inorganic salt is constantly secreted by granulocyte the piling up and formed of Concha Ostreae.In the formation of Concha Ostreae, organic-biological
As framework, induced crystal is formed so that Calcium Carbonate molecule is constantly orderly piled up macromole, gradually form have highly denser
The tridimensional network of degree.Concha Ostreae is mainly made up of three-decker, and outermost layer is the hardened proteins horny layer of very thin thickness,
Centre is calcareous fiber interweaving, the prismatic layer containing more natural pore, is mainly made up of calcite, internal layer is nacreous layer,
Mainly it is made up of aragonite.In the three-decker of Concha Ostreae, topmost prismatic layer, in bladed structure, containing a large amount of micropores,
After calcining, CO2 excludes, and remaining main component is calcium oxide, and material is decomposed, and duct originally changes, and is formed
Complicated porous structural, the material composition of Concha Ostreae is divided into inanimate matter and organic two parts, and inanimate matter part calcium carbonate is
Main, account for Concha Ostreae quality more than 90%, wherein, calcium constituent accounts for 39.78%, additionally it contained copper, ferrum, zinc, manganese, strontium etc. more than 20
Plant trace element；The organic principle of Concha Ostreae accounts for the 3-5% of Concha Ostreae quality, containing glycine, cystine, Methionine etc. 17
Middle aminoacid.
Calper calcium peroxide, chemical molecular formula CaO2, is a kind of important inorganic chemical product, white to yellowish no color or smell,
Slow release oxygen in water and humid air, to can be used as antibacterial, preservative, leaven, oils bleach and closing earth rubber fast
Dry agent and oxygen supplement oxygenate.When but calper calcium peroxide directly uses, it is faced with and meets water wet gas excessively quick release oxygen
Defect and deficiency.Due to hydrogen peroxide and appropriate water generating stable peroxide calcium crystal can be combined by calcium oxide, such as change
Shown in formula, CaO+H2O2+7H2O → CaO2 8H2O, in this reaction system, need the calper calcium peroxide crystal generating is entered
A series of programs such as row filtration, flushing, heat drying just can obtain stable calper calcium peroxide.
Concha Ostreae wide material sources, develop the slow-release fertilizer of high efficiency low cost by Concha Ostreae, and the utilization rate improving fertilizer is had
Great meaning.

Moisture adjuster vermiculite power etc., is easy to plant absorption and utilizes, simultaneously by inorganic moisture adjuster adjust automatically salt-soda soil soda acid
Degree, improves the resistance of salt-soda soil Semen Coicis, adopts the coating layer that can adjust hole with oxygen supply and dynamically, and fertilizer efficiency time is long, Neng Gouchang
The release organic matter nutrient of time, promotes the Efficient Cultivation of salt-soda soil Semen Coicis；The coating layer being adopted is received using Concha Ostreae, activation
Rice attapulgite, viscosity loess are prepared from, and Concha Ostreae is reacted generation under calcining, alkaline environment and stablizes peroxide with hydrogen peroxide
Change calcium crystal and alkali liquor, stable peroxide calcium crystal through poly- propionic acid amide., polylactic acid peplos postactivated with nano-attapulgite, viscosity
Loess, directly in conjunction with preparing coating layer, and the moisture of the volume drying removal calper calcium peroxide crystal through fertiliser granulates, is realized adding
Carry the fertilizer coating layer of stable peroxide calcium, system to overcome calper calcium peroxide quick release soluble in water oxygen inconvenience directly sharp
Defect in sustained slow-release fertilizer and deficiency；Meanwhile, sweat becomes to make full use of alkali liquor, improves raw material utilization efficiency,
And overcome fermentation sour environment to zymogenic suppression, improve fermentation efficiency, enrich the nutrition of fertilizer and absorbable profit
Small-molecule substance content；
During the use of this coated fertilizer, rich in calper calcium peroxide coating layer in the presence of water, calper calcium peroxide is reacted with water, and one
Part release oxygen generates with adhesive property and bactericidal calcium hydroxide, the hole of one side dynamic regulation coating layer simultaneously
Gap, the release efficiency of adjustment fertilizer, slows down the disintegration rate of coating layer, on the other hand promotes the metabolism of plant, concrete table
Now as follows:One is can to break that urban soils are hardened, chesson, improve the gas permeability of soil so that affined nutrient and
Moisture significantly more efficient motion in soil, can improve soil microorganism colony sum and specific diversity, strengthen soil rich water
Penetration, minimizing pest and disease damage occur, and two is that the anaerobic condition that oxygen improves plant root that provides that can be continual and steady promotes to plant a root system
Growth promoter, there is the effect of double gain, high cost coated fertilizer can be replaced to a certain extent.
Extensively, Costco Wholesale is low, and preparation technology is simple to operate for the coated fertilizer material source of the present invention, and effect is notable, energy
Enough extensively applications and popularization.
