Description
Technical field
The present invention relates to a kind of synergistic agent for urea and preparation method thereof and using method.
Background technology
Urea is China's main nitrogenous fertilizer at present, and China's ultimate production in 2010 is 4,521 ten thousand tons (pure), and wherein blood urea nitrogen output is 2,516 ten thousand tons (pure).These urea are mainly applied directly to farmland or are used for producing compound (mixing) fertilizer or bulk blended fertilizer as raw material.Urea has that nitrogen content is high, steady performance.But in use exist the problems such as utilization ratio is low, loss is serious, fertilizer efficiency period is short.The average utilization of China's urea only has 30%, and fertilizer efficiency period only has 35 days.The direct economic loss causing due to the loss of blood urea nitrogen every year, more than 60,000,000,000 yuans, is left the nitrogen in farmland or has polluted underground water, or having caused red tide and wawter bloom, or becoming greenhouse gases.Day by day serious along with farmland pollution of area source, the utilization ratio that improves urea is extremely urgent.Studies confirm that: it is damnous major cause that urea enters the biochemical reaction carrying out after soil too fast, and urea is hydrolyzed to ammonium nitrogen after entering soil under the effect of soil urease, when the higher and temperature of enzymic activity is higher, urea complete hydrolysis in three days is complete.In the so short time, adsorption by soil amount and Crop amount are limited, and a large amount of nitrogens evaporate in air with the form of ammonia.In this process, urase is key point, can, by controlling the activity of urase, delay the hydrolysis of urea.Urease inhibitor can, by suppress the activity of part urase within certain period, delay the hydrolysis of urea, make nitrogen with the form of blood urea nitrogen exist with soil in, reduce the volatilization of ammonia, and extend the fertilizer efficiency period of urea.Normal-butyl thiophosphoryl triamine is one urease inhibitor safely and efficiently, effect significantly and to environment without any negative effect.Together with after normal-butyl thiophosphoryl triamine is mixed with urea, be administered in soil, can delay the hydrolysis of urea, reduce ammonia loss by volatilization, improve the utilization ratio of urea, extend the fertilizer efficiency period of urea.But the production system of urea is the holonomic system of a High Temperature High Pressure, non-crystallizable in order to guarantee urea solution, system temperature is not less than 120 ℃, for the change complex procedures of production system and there is risk.Normal-butyl thiophosphoryl triamine there will be slow decomposition at the temperature higher than 60 ℃ simultaneously.The general method that uses normal-butyl thiophosphoryl triamine is to spray to urea granules surface after making the liquid dosage forms such as missible oil after being dissolved with organic solvent, this method bonds after easily causing urea moisture absorption, has that organic solvent price is high, complex production process, organic solvent exist the problems such as risk to people and soil simultaneously.
Summary of the invention
The present invention to solve existing normal-butyl thiophosphoryl triamine make spray to after the liquid dosage forms such as missible oil the urea granules bonding, complex production process, the organic solvent valency that bring on urea granules surface high, be there is to the problem of risk in people and soil, and provide a kind of synergistic agent for urea and preparation method thereof and using method.
A kind of synergistic agent for urea is mixed and is formed by normal-butyl thiophosphoryl triamine and lignite humic acid, and described normal-butyl thiophosphoryl triamine and the mass ratio of lignite humic acid are 100:(500～5000).
A kind of preparation method of the synergistic agent for urea, specifically complete according to the following steps: first normal-butyl thiophosphoryl triamine is dropped in agitator, then add lignite humic acid, stirring and evenly mixing, obtain mixture, mixture is imported to micronizer mill, and it is more than 500 orders setting micronizer mill smashing fineness, obtains the synergistic agent for urea after having pulverized.
A kind of using method of the synergistic agent for urea, specifically complete according to the following steps: by the synergistic agent usage quantity 100g/ mu～2000g/ mu for urea by the synergistic agent for urea and urea is manually puddled or machinery is puddled, obtain synergistic agent/urea admixture, then synergistic agent/urea admixture is spread fertilizer over the fields, ditch spread or spread manuer in holes in soil; Urea in described synergistic agent/urea admixture: for the mass ratio >=10:1 of the synergistic agent of urea.
Advantage of the present invention: rear to be crushed to fineness with micronizer mill be more than 500 orders by normal-butyl thiophosphoryl triamine and humic acids are mixed in the present invention, and control each component proportion, makes synergistic agent.This synergistic agent is very easily adsorbed onto urea granules surface after contacting with urea.This synergistic agent and urea are mixed, carry out simple manually or machinery puddle and can make synergistic agent evenly be adsorbed onto urea granules surface, use farmland, can improve the utilization ratio of urea, the loss that reduces nitrogen and prolongation fertilizer efficiency period, it is short and lose serious problem to have solved the urea efficiency phase, solved simultaneously normal-butyl thiophosphoryl triamine make spray to after the liquid dosage forms such as missible oil the urea granules bonding, complex production process, the organic solvent valency that bring on urea granules surface high, be there is to the problems such as risk in people and soil.
