A synergy loss controlling fertilizer, described polyacrylamide fineness >=100 order.
A synergy loss controlling fertilizer, described chelated ferrous iron molecular formula is FeEDTA, containing Fe >=12.0%.
A preparation method for synergy loss controlling fertilizer, comprises the following steps:
(1) ammonium chloride, ammonium sulfate, bicarbonate of ammonia are added in chain breaker, carry out fragmentation by weight, again broken material is sent in twin-shaft mixer, after fully mixing with zeolite powder, Sodium salts humic acids, polyacrylamide, asbestos powder, brown sugar, chelated ferrous iron, potassium para-nitrophenate, the additive of metering, then send in granulating disc or rotary drum granulator;
(2) in granulating disc or rotary drum granulator, to bed of material, spray ammonium nitrate solution, material rolling reunion granulating;
(3) particle after granulation is carried out to one section of dry, one section of cooling and thickness screening, after screening, the particle of particle diameter 2.00-4.75mm enters in coating machine, is greater than 4.75mm macrobead and returns to fragmentation, is less than 2.00mm particulate and returns to granulation;
(4) oil-like anti-caking agent is used plunger metering pump to pass through the even sprayed particle of atomizing nozzle surface in coating machine, make functional nitrogenous fertilizer.
(5) by weight urea and functional nitrogenous fertilizer are sent in single bag of batching blending equipment, through blending, automatic quantitative packing, made finished product.
Advantage of the present invention is as follows:
(1) extend the fertilizer efficiency time, improve utilization rate of fertilizer.In product, nitric nitrogen, ammonium nitrogen are easily directly absorbed by crop, put forward fast fertilizer efficiency; Amidonitrogen need be converted into after ammonium nitrogen under urase effect, and just utilization absorbed by crops extends fertilizer efficiency period; Zeolite powder has the complex three-dimensional spatial skeleton structure by oxygen, silicon and three kinds of atomic buildings of aluminium, in skeleton structure, exist cavity and duct, there is good absorption property, cation exchange property and acidproof, resistance toheat, can form the micro-nano network structure of omnibearing stereo, under the effect of moisture penetration, zeolite powder can stick in polyacrylamide absorption self colloidal solid around, form a kind of structure with control mistake effect, net is caught fertilizer nutrient molecule, slow down the velocity of diffusion of nutrient, reduce it with the loss of moisture; Sodium salts humic acids contains the functional groups such as carboxyl, phenolic hydroxyl group, has stronger ion-exchange and adsorptive power, can reduce the loss of ammonium nitrogen, improve utilization rate of nitrogen fertilizer, humic acids functional group can absorb storage potassium ion, and potash fertilizer is slowly decomposed, increase the burst size of potassium, improve the content of available potassium.Product is combined different shape nitrogen with zeolite powder, Sodium salts humic acids, polyacrylamide, asbestos powder, brown sugar and additive, more can delay the release period of nutrient, improves utilization rate of fertilizer, and the pollution that has alleviated water quality and atmosphere, has protected environment.
(2) improve fertilizer efficiency, increasing both production and income.Potassium para-nitrophenate has and promotes cellular plasm to flow, and improves cell viability, and short root strong sprout, flower and fruit protecting, increases anti-adversity ability, removes the effects such as antagonism between fertilizer, increases the utilize speed of plant to fertilizer, improves the absorption of crop to npk nutrient; Sulphur is the essential middle amount nutritive element of plant growth, iron energy involved in plant Cellular Oxidation reduction reaction and electronics transmission, synthesize chlorophyll (chl), nitrogen, sulphur, iron coordinate more and can improve crop economy proterties with Sodium salts humic acids, strengthen crop anti-adversity, improve crop yield, improve quality of agricultural product.Use this product and can reduce rate of fertilizer application, indirectly saved resource; Reduce fertilizer application frequency, reduce fertilising cost, increase economic benefit, the while can be avoided disposable using in a large number and occur burning seedling phenomenon, has reduced the trouble of topdressing in part dense planting crop later stage field.
(3) improvement and fertilizing soil.Humic acids is as the significant energy source of soil microorganisms and the matrix of soil beneficial microorganism breeding, can increase the content of soil with organic matter, effectively improve water, fertilizer, gas, the thermal conditions of soil, make soil become loose, promote the formation of soil aggregate; Zeolite powder and polyacrylamide have the features such as good adsorptivity, water-retentivity, agglutinating value(of coal), can improve the materialization property of soil, improve the hydrothermal condition of soil, can also adsorb the harmful element in soil, alleviate the pollution of soil.
(4) less investment, high efficiency.Raw material sources are wide, obtain easily, cheap, effectively reduce batching cost, and anti-hard caking agent material non-toxic, free from extraneous odour, easily degraded, do not exist secondary pollution problem.Production technique is simple, easy to operate, and facility investment is few, and granulation balling ratio is high, enhances productivity, and reduces energy consumption.
(5) good product performance, market outlook are wide.Product appearance is smooth, mellow and full, and intensity is high, and moisture is low, do not lump, and not efflorescence, product granularity is even, blending is not emanated, suitable for mechanization fertilising; Product colour is part white and part black, facilitates user to identify; Product can be mixed with the particle phosphorus potash fertilizer of same particle diameter and produce the bulk blended fertilizer with synergy loss controlling energy.
