Abstract
The invention discloses an acidic soil conditioner being strong in adsorption and containing silicon, calcium and potassium. The acidic soil conditioner is prepared from following raw materials: potassium feldspar, limestone, medical stone and an additive, sodium metasilicate. A preparation method comprises following steps: crushing the potassium feldspar and the limestone respectively through a crushing machine and uniformly mixing the potassium feldspar and the limestone and grinding the potassium feldspar and the limestone through a ball miller; (2) placing the fine mixed material in a disk-type pelletizer, and performing granulation with a sodium metasilicate solution being 30% in concentration as a binding agent; (3) drying wet granules after granulation in a drier for being dried and then sieving the dried granules through a vibrating screen; (4) feeding sieved granules to a calcining kiln to calcine the granules, cooling and jaw-breaking the granules, and mixing the granules with the medical stone in 100 meshes; and (5) grinding the mixture through the ball miller to form a fine powder to obtain the acidic soil conditioner being strong in adsorption and containing silicon, calcium and potassium. In the soil conditioner, a mutual effect among the raw materials is achieved, wherein the alkalinity of the limestone can enable pH value of soil to be adjusted and a requirement of different micro-scale elements during different growth periods of crops can be satisfied by the silicon, the calcium and the potassium. The soil conditioner has a long-period slowly-releasing function.
Description
Technical field
The invention belongs to agricultural fertilizer field, relate to a kind of acidic soil conditioner with strong adsorptivity containing calcium silicon potassium element specifically.
Background technology
Agriculture production uses chemical fertilizer for a long time and pursues Agriculture Production Modes for the purpose of the maximization of unit revenue from domains, and determine China's current soil acidification phenomenon fairly obvious, particularly soil acidification phenomenon in rice producing areas of southern China is more outstanding.For improving soil, rehabilitating soil, 12 countries propose the slogan building beautiful China.In this context, soil conditioner occurs like the mushrooms after rain.Mostly amendment is organic matter is at present main, improves by supplementary organic matter the object that soil micro reaches improvement soil.This amendment shortcoming to supplement the pH value that medium trace element can not change soil, undesirable to the improvement of acid soil.Function singleness, peasant uses inconvenience.
Summary of the invention
Object of the present invention is just to provide a kind of acidic soil conditioner and the preparation method with strong adsorptivity containing calcium silicon potassium element, and this amendment has can adsorb harmful heavy metal in soil, improves contaminated soil environment, promotes effect of crop quality.
Object of the present invention realizes by following technical scheme:
Have an acidic soil conditioner for strong adsorptivity containing calcium silicon potassium element, be made up: potassium felspar sand 155-195 of following raw material, Wingdale 30-50 part, medical stone 155-215 part, auxiliary agent Starso is the 7%-9% of potassium felspar sand and Wingdale gross weight.
The above-mentioned acidic soil conditioner with strong adsorptivity containing calcium silicon potassium element, is made up of following raw material: potassium felspar sand 175,40 parts, Wingdale, medical stone 185 parts, and Starso is 8% of potassium felspar sand and Wingdale total amount.
The above-mentioned preparation method with the acidic soil conditioner of strong adsorptivity containing calcium silicon potassium element, comprises the following steps:
A. take potassium felspar sand, Wingdale, Starso and medical stone by weight, by potassium felspar sand and lime respectively by crusher in crushing to the granularity of 10-20mm, potassium felspar sand and Wingdale mix, with grinding of ball grinder to 90% material by 100 mesh standard sieves;
B. by levigate above-mentioned compound, be placed in pan-type pelletizer, with the sodium metasilicate solution of 30% concentration for binding agent carries out granulation, consumption of binder is about the 7%-9% of compound, wet granular after granulation enters drying machine and carries out drying, then chooses the particle of granularity 4-6mm with vibratory screening apparatus;
C. particle enters calcining kiln, at 1050 ~ 1100 DEG C of temperature lower calcination 0.8-1.2 hour, then after being cooled to normal temperature, Hubei Province is broken, mix with 100 object medical stones, again with ball mill by levigate for mixed batch mixing to 90% by 300 mesh sieves, the obtained acidic soil conditioner with strong adsorptivity containing calcium silicon potassium element.
The above-mentioned preparation method with the acidic soil conditioner of strong adsorptivity containing calcium silicon potassium element, described step c particle enters calcining kiln, at 1050 ~ 1100 DEG C of temperature lower calcination 0.8-1.2 hour, then after being cooled to normal temperature, Hubei Province is broken, mix with 100 object medical stones, again with ball mill by levigate for mixed batch mixing to 90% by 300 mesh sieves, the obtained acidic soil conditioner with strong adsorptivity containing calcium silicon potassium element.
The above-mentioned preparation method with the acidic soil conditioner of strong adsorptivity containing calcium silicon potassium element, described step b. is by levigate above-mentioned compound, be placed in pan-type pelletizer, with the sodium silicate solution of 30% concentration for binding agent carries out granulation, consumption of binder is about 8% of compound; Step c particle enters calcining kiln, and 1050 ~ 1100 DEG C of temperature lower calcinations 1 hour, after being cooled to normal temperature, Hubei Province was broken.
The present invention is with potassium felspar sand, Wingdale and medical stone for raw material, and medical stone is a kind of to biological nontoxic, harmless and have certain bioactive composite minerals or medicinal rock.The main chemical compositions of medical stone is inorganic silico-aluminate.Comprising SiO2, Al2O3, Fe2O3, FeO, MgO, CaO, K2O, Na2O, TiO2, P2O5, MnO etc., also containing the whole major elements needed for animal, as: the trace element such as K, Na, Ca, Mg, Cu, Mo and rare earth element, about 58 kinds more than.Medical stone also has high absorption Thief zone function.K contained in potassium felspar sand is the important element of crop growth.Silicon, calcium and potassium element its activity in high-temperature burning process is activated, and form citric soluble silicon-calcium-potafertilizer fertilizer, citric soluble silicon-calcium-potafertilizer fertilizer not easily runs off in acid soil.In the present invention, each raw material interacts, the alkalescence of Wingdale not only can regulate the pH value of soil, and the elements such as silico-calcium potassium can also be made to meet Different Crop in the demand of different growth cycles to different medium trace element, reach long-acting slow-release function, the third aspect, medical stone can also adsorb the harmful heavy metal in soil, improves contaminated soil environment, promotes crop quality.And raw material of the present invention is easy to get, preparation technology simple, thus reduces production cost, and this product result of use is good, is applicable to applying.
