Description
Technical field
The present invention relates to a kind of synergy chemical fertilizer, is the chemical fertilizer of nitrogenous, phosphorus, potassium for improving crop yield and control nitrogen synergistic agent (AHE) specifically.
Background technology
The composite fertilizer that current China agriculturally uses, compound manure all belong to nitrogenous, the composite fertilizer (National Standard of the People's Republic of China GB15063-2009 " composite fertilizer-compound manure ") of phosphorus, potassium three kinds of nutrients or wherein two kinds of nutrients.In composite fertilizer, nitrogen element is that crop growth is necessary, is also the nutritive element had the call.Nitrogen 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 being raw material production with these fertilizer 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: one is that major nitrogen source urea contained in composite fertilizer is with after incorporation of fertilizerin the soil, farm crop seldom absorb, having to pass through urase hydrolysis contained in soil is ammonium nitrogen, and crop just can absorb.Reaction formula is:
Because the crop absorption of full vegetative period to nitrogen has from less to more, arrive the rule of few constant absorption again, only have the conversion of fertilizer nutrient to discharge the regulation of fertilizer requirement meeting crop and could realize stable and high yields, and the speed of the hydrolysis of urea in composite fertilizer absorbs to require it is not synchronous with crop nutrition content.(He Weiming etc. " Chinese soil and fertilizer " " progress of nitrogen fertilizer potentiating agent and effect assessment thereof " 2011.3.P 1-7), the ammonia loss by volatilization of urea at short notice caused by hydrolysis accounts for its total amount 10 ~ 50%, is one of reason that Nitrogen utility is low (Wu Zhijie etc. (" release/controlled release principle and characteristics " Science Press 18,2003).Second reason is: the volatilization loss of the ammonia that nitrated-anti-nitre effect causes, 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
2air escape.Between this loss amount accounts for 30% ~ 55% greatly (Zhu Zhaoliang, China's soil-tillage system and fertilizer nitrogen whereabouts progress of research, soil 1985,17:2-9).3rd reason is leaching loss: the nitric nitrogen NO that nitrification produces
3-N.Although be the nitrogen that crop Absorbable rod utilizes, but because nitric nitrogen is with negative charge, and soil colloid is also with negative charge, so can not be adsorbed by soil colloid, movability in soil is large, very easily outflow with water enter in water body lose (Wu Zhijie etc. " release/controlled release principle and characteristics " Science Press, 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 enters air and water body with variform, and it is huge that the air caused and water pollution, environmental pollution affect.
By the end of 2010, China permits that composite fertilizer manufacturing enterprise on the regular payroll just reaches 4400, aggregated capacity quantity of goods produced is more than 200,000,000 tons, actual annual production is 5,000 ten thousand tons, composite fertilizer nitrogen content average more than 15%, calculate by utilization rate of nitrogen fertilizer 35%, China just reaches 487.5 ten thousand tons by means of only the purity nitrogen volatilization leaching loss using composite fertilizer to bring every year, produce 1 ton of purity nitrogen and need standard coal 1.33 tons, 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, financial loss 62.2 hundred million yuans, the volatilization leaching of nitrogen that causes because composite fertilizer utilization rate of nitrogen fertilizer is low every year of China is discharged to air with the exception of this, the Environmental Pollution Loss that water body causes cannot be estimated.
