A kind of synergy loss controlling fertilizer, described polyacrylamide fineness >=100 order.
A kind of 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 the material of fragmentation is sent in twin-shaft mixer, after fully mixing with the zeolite powder measured, Sodium salts humic acids, polyacrylamide, asbestos powder, brown sugar, chelated ferrous iron, potassium para-nitrophenate, additive, then send in granulating disc or rotary drum granulator;
(2) in granulating disc or rotary drum granulator, ammonium nitrate solution is sprayed to bed of material, material rolling reunion granulating;
(3) particle after granulation is carried out one section of drying, one-step 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 fragmentation, be less than 2.00mm particulate and return granulation;
(4) in coating machine, plunger metering pump is used by oil-like anti-caking agent to pass through atomizing nozzle even application particle surface, obtained functional nitrogenous fertilizer.
(5) by weight urea and functional nitrogenous fertilizer being sent into single bag prepares burden in blending equipment, through blending, automatic quantitative packing, and obtained 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; After amidonitrogen need be converted into ammonium nitrogen under urase effect, just utilization absorbed by crops, extends fertilizer efficiency period; Zeolite powder has the complex three-dimensional spatial skeleton structure by oxygen, Silicified breccias three kinds of atomic buildings, cavity and duct is there is in skeleton structure, there is excellent absorption property, cation exchange property and acidproof, resistance toheat, the micro-nano network structure of omnibearing stereo can be formed, under the effect of moisture penetration, polyacrylamide absorption can stick in around self colloidal solid by zeolite powder, form a kind of structure with control mistake effect, Fertilizer nutrient molecule caught by net, slow down the velocity of diffusion of nutrient, reduce its loss with moisture; Sodium salts humic acids contains the functional group 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 Potassium release amount, improve the content of available potassium.Different shape nitrogen is combined with zeolite powder, Sodium salts humic acids, polyacrylamide, asbestos powder, brown sugar and additive by product, more can delay the release period of nutrient, improves utilization rate of fertilizer, alleviates the pollution of water quality and air, protect environment.
(2) fertilizer efficiency is improved, increasing both production and income.Potassium para-nitrophenate has and promotes cellular plasm flowing, improves cell viability, short root strong sprout, flower and fruit protecting, increases anti-adversity ability, removes the effects such as antagonism between fertilizer, increase plant to the speed that utilizes of fertilizer, improve crop to the absorption of npk nutrient; Sulphur is the required middle amount nutritive element of plant growth, the reaction of iron energy involved in plant cellular redox and electron transmission, synthesize chlorophyll (chl), nitrogen, sulphur, iron coordinate with Sodium salts humic acids more can improve crop economy proterties, strengthen crop anti-adversity, improve crop yield, improve quality of agricultural product.Use this product and can reduce rate of fertilizer application, indirectly save resource; Reduce fertilizer application frequency, reduce fertilising cost, increase economic benefit, can disposable using in a large number be avoided simultaneously and occur burning seedling phenomenon, decreasing the trouble topdressed in part dense planting crop later stage field.
(3) improvement and fertilizing soil.The significant energy source of humic acids as soil microorganisms and the matrix of soil beneficial microorganism breeding, the content of soil with organic matter can be increased, effectively improve the water of soil, fertilizer, gas, thermal conditions, 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, anti-hard caking agent material non-toxic, free from extraneous odour, easily degrade, and there is not secondary pollution problem.Production technique is simple, and easy to operate, facility investment is few, and granulation balling ratio is high, enhances productivity, and reduces energy consumption.
(5) good product performance, wide market.Product appearance is smooth, mellow and full, and intensity is high, and moisture is low, does not lump, not efflorescence, and product granularity is even, blending is not emanated, and suitable for mechanization applies fertilizer; Product colour is partial white and part black, facilitates user to identify; Product can produce the bulk blended fertilizer with synergy loss controlling energy with the particle phosphorus potash fertilizer mixture of same particle diameter.
