Description
Technical field
The present invention relates to a kind of synergy chemical fertilizer, is the chemical fertilizer of nitrogenous, phosphorus, potassium and control nitrogen synergistic agent (AHE) for improving crop yield specifically.
Background technology
That composite fertilizer, the compound manure using in China's agricultural at present all belongs to is nitrogenous, phosphorus, three kinds of nutrients of potassium or the composite fertilizer of two kinds of nutrients (State Standard of the People's Republic of China GB15063-2009 < < composite fertilizer-compound manure > >) wherein.In composite fertilizer, nitrogen element is that crop growth is necessary, is also the nutritive element having the call.Nitrogenous source raw material used during manufacture is mainly with nitrogenous chemical fertilizer such as urea, ammonium sulfate, ammonium chloride, monoammonium phosphates, the composite fertilizer utilization rate of nitrogen fertilizer that these fertilizer are raw material production of take is low, its utilization rate of nitrogen fertilizer is only 30%～35% (Zhang Fusuo etc., Chinese staple food crop utilization rate of fertilizer present situation and raising approach soil journal: 2008.45(5): P915-922).The number of utilization rate of fertilizer is direct affects crop yield, the major cause that composite fertilizer utilization rate of nitrogen fertilizer is low has 3 points: the one, in composite fertilizer contained major nitrogen source urea with incorporation of fertilizerin the soil after, farm crop seldom absorb, must be ammonium nitrogen through contained urase hydrolysis in soil, crop just can absorb.Reaction formula is:
Because crop has from less to more the absorption of nitrogen full vegetative period, arrive again the rule of few lasting absorption, only have the conversion of fertilizer nutrient to discharge to meet the regulation of fertilizer requirement of crop could realize stable and high yields, and the speed of the hydrolysis of urea in composite fertilizer absorb requirement with crop nutrition content and does not synchronize.(< < Chinese soil and fertilizer > > " progress of nitrogen fertilizer potentiating agent and effect assessment thereof " the 2011.3.P 1-7 such as He Weiming), the urea at short notice caused ammonia loss by volatilization of hydrolysis accounts for its total amount 10～50%, is that nitrogen utilizes one of low reason (Wu Zhijie etc. (< < release/controlled release principle and application > > Science Press 18,2003).Second reason is: the volatilization loss of the ammonia that nitrated-anti-nitre effect causes, and the volatilization loss of ammonia is except urea, and the loss access of the nitrogen of the ammonium fertilizers such as the ammonium sulfate in composite fertilizer raw material, ammonium chloride, monoammonium phosphate is consistent.If the gaseous oxygen compound of nitrogen is (as NO
x, N
2o etc.) the final product N of anti-nitre effect
2atmosphere escape.Between this loss amount accounts for 30%～55% greatly (Zhu Zhaoliang, China's soil is for nitrogen and fertilizer nitrogen whereabouts progress of research, soil 1985,17:2-9).The 3rd reason is leaching loss: the nitric nitrogen NO that nitrification produces
3-N.Although be the nitrogen that crop can absorb, but because nitric nitrogen is with negative charge, and soil colloid is also with negative charge, so can not adsorbed by soil colloid, movability in soil is large, very easily outflow with water enter in water body loss (the < < release/controlled release principle and application > > Science Press such as Wu Zhijie, 2003:; 17).Above 3 is the major cause that composite fertilizer utilization rate of nitrogen fertilizer is low.Because composite fertilizer utilization rate of nitrogen fertilizer is low, the nitrogen of loss has entered atmosphere and water body with variform, and the atmosphere causing and water pollution, environmental pollution impact are huge.
By the end of 2010, China permits composite fertilizer manufacturing enterprise on the regular payroll just to reach 4400, aggregated capacity quantity of goods produced is over 200,000,000 tons, actual annual production is 5,000 ten thousand tons, composite fertilizer nitrogen content is average more than 15%, pressing utilization rate of nitrogen fertilizer 35% calculates, China is often only by using the purity nitrogen volatilization leaching loss that composite fertilizer brings just to reach 487.5 ten thousand tons, produce 1 ton of purity nitrogen and need 1.33 tons of standard coals, by standard coal price 960 yuan of calculating per ton in 2010, the mark coal losses that only this item China causes because utilization rate of nitrogen fertilizer is low every year reaches 6,480,000 tons, 62.2 hundred million yuans of financial losses, China is every year because the volatilization leaching of the low nitrogen causing of composite fertilizer utilization rate of nitrogen fertilizer is discharged to atmosphere with the exception of this, the Environmental Pollution Loss that water body causes cannot be estimated.
