Description
Technical field
The present invention relates to slow release fertilizer technical field, more particularly to a kind of Herba Alii fistulosi rich in trace element efficiently plant fertilizer and
Its preparation method.
Background technology
Chemical fertilizer plays the important and pivotal role in terms of grain yield is improved as important agriculture data, 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 point is with seepage and steaming
Send out and be lost in air and subsoil water, not only waste serious, and the environmental pollutions such as soil, air, subsoil water can be caused.Cause
This, is modified to fertilizer, and it is to reduce fertilizer to use to improve fertilizer efficiency, the effective way increased operation rate.Such as current slow-release or control-release fertilizer
One of effective measures of chemical fertilizer utilization ratio are improved exactly, slow-release or control-release fertilizer can efficiently control the release of nutrient, extend fertilizer efficiency period, expires
The whole period of duration of sufficient crop to the needs of fertilizer nutrient, can improve to greatest extent fertilizer utilization rate, 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.
Concha Ostreae constantly being secreted inorganic salt by granulocyte and piles up and formed.In the formation of Concha Ostreae, organic-biological
Macromole is formed as framework, induced crystal so that Calcium Carbonate molecule is constantly orderly piled up, and is gradually formed with 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, and 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 is excluded, 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 are divided into inanimate matter and organic matter two parts, and inanimate matter part calcium carbonate is
It is main, Concha Ostreae quality more than 90% is accounted for, 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,
It is slow in water and humid air to discharge oxygen, can be used as antibacterial, preservative, leaven, oils bleach and close earth rubber fast
Dry agent and oxygen supplement oxygenate.When but calper calcium peroxide is directly used, it is faced with and meets water wet gas excessively quick release oxygen
Defect and deficiency.As 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 the reaction system, need to enter the calper calcium peroxide crystal for generating
A series of programs such as row filtration, flushing, heat drying can just 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 to improving fertilizer has
Great meaning.

(4) ball-type fertiliser granulates are placed into rolling on fluid bed, by step in high temperature with high-pressure nozzle and air cooking(1)
To coating liquid repeat uniformly to be sprayed at ball-type fertiliser granulates 3-5 time by high-pressure nozzle, coordinate 131.5- during sprinkling every time
140 DEG C of air cooking, it is to be operated to finish, 1.8-2h is being dried using 42.5-50 DEG C, cooling down, it is packed to obtain final product.
It is an advantage of the invention that:
The present invention using potassium breeze, manioc waste, alditol slag, the dregs of fat coordinate green vitriol, magnesium sulfate, potassium dihydrogen phosphate,
The nutrient substance Jing yeast such as Aminoacids complex powder, fulvic acid, sodium acetate, zinc glycinate, ferrum glycinate, Mn-Gly, phosphorus are thin
A kind of coated slow release fertilizer is prepared for after bacterium, B. mucilaginocus fermentation, fertilizer itself is rich in organic matter, mineral element and micro unit
Element, it is nutritious, adopt can with oxygen supply and dynamic adjustment hole coating layer, fertilizer efficiency time is long, and can discharge for a long time has
Machine matter nutrient, can promote Herba Alii fistulosi metabolism, improve its N,P use efficiency, promote its growth and photosynthesis, improve which right
The utilization ratio of fertilizer, stout and strong meat Herba Alii fistulosi plant improve protein, cellulose, mineral element, micronutrient levelss, improve
Its quality, realizes its Efficient Cultivation;The coating layer for being adopted is prepared using Concha Ostreae, sodium bentonite, nanoscale viscosity clay
Form, Concha Ostreae generates stable peroxide calcium crystal and alkali liquor, stable peroxide under calcining, alkaline environment with hydrogen peroxide reaction
Change calcium crystal Jing after polylactic acid peplos with sodium bentonite, nanoscale viscosity clay directly in conjunction with preparing coating layer, and through fertilizer
The volume drying of material granule removes the moisture of calper calcium peroxide crystal, realizes the fertilizer coating layer of loading stable peroxide calcium, system
Overcome the inconvenience of calper calcium peroxide quick release oxygen soluble in water directly using the defect and deficiency in sustained slow-release fertilizer;Together
When, sweat improves raw material utilization efficiency, and overcomes fermentation sour environment to zymogenic suppression into alkali liquor is made full use of
System, improves fermentation efficiency, enriches the nutrition of fertilizer and the absorbable small-molecule substance content for utilizing;
During the use of the coated fertilizer, rich in calper calcium peroxide coating layer in the presence of water, calper calcium peroxide is reacted with water, and one
Release oxygen in part generates the calcium hydroxide with adhesive property, the hole of one side dynamic regulation coating layer, adjustment fertilizer simultaneously
The release efficiency of material, slows down the disintegration rate of coating layer, on the other hand promotes the metabolism of plant, and concrete manifestation is as follows:One
It is can to break hardened urban soils, chesson, improve the gas permeability of soil, so that affined nutrient and moisture are in soil
In significantly more efficient motion, can improve soil microorganism colony sum and specific diversity, strengthen soil rich water penetration, reduce
Pest and disease damage occurs, and two is the growth promoter for providing the anaerobic condition promotion kind root system that oxygen improves plant root that can be continual and steady,
With the effect killed two birds with one stone, 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.
