Embodiment
The production process of carbon containing chemical fertilizer, especially bicarbonate of ammonia is CO
2, H
2O, NH
3The addition reaction of compound forms the molecular clustering compound.Bicarbonate of ammonia molecular clustering compound is a kind of loose polymer, contains the moisture more than 3% again.Moisture itself is that bicarbonate of ammonia decomposes the evaporable catalyzer, makes and contains 56%CO
2Bicarbonate of ammonia be manured into soil after, resolve into NH again
3And CO
2Be discharged in the atmosphere, produce Greenhouse effect.The present invention introduces the nano-sized carbon of granularity at 5-200nm in the bicarbonate of ammonia chemical fertilizer production process, the preferred nano-sized carbon of introducing granularity at 5-100nm, especially 5-70nm, at resulting bicarbonate of ammonia compound manure is in bicarbonate of ammonia molecular clustering compound open structure, filling nano level nano-sized carbon, changed loose bicarbonate of ammonia structure thus, reduced the moisture content in the bicarbonate of ammonia bunch lattice, make its structure tight, become from disordered structure and to be ordered structure, make bicarbonate of ammonia thermostability, water stability strengthen, volatility reduces.Because the reduction of greenhouse gas discharge effect can be directly played in the functional effect of nano-sized carbon.
The many forms with ammonium nitrogen of nitrogen manure enter soil in being manured into soil, effect through the soil nitrate reductase is converted into nitric nitrogen, nitric nitrogen is easily utilized by plant absorbing, but often owing to transform too fast, semi-invariant is too much, plant fails all to absorb, and produces leaching and denitrification nitrogen is run off in a large number, causes rivers and lakes water system pollution of area source.The nitrite nitrogen that denitrification produces is a kind of strong carcinogen.The further oxidation of nitrite nitrogen can form a large amount of Nitrous Oxide (N
2O), the Nitrous Oxide (N that normally applies fertilizer
2O) annual emissions is 1%~4% of an amount of nitrogen, and one ton of Nitrous Oxide (N
2O) carbon value tax is equivalent to 310 tons of CO
2The carbon value tax, Nitrous Oxide (N
2O) be a kind of to the extremely strong greenhouse gases of depletion of the ozone layer.And the bicarbonate of ammonia that combines nano-sized carbon can delay the process that ammonium nitrogen changes into nitric nitrogen and nitrite nitrogen in soil, and then can reduce Nitrous Oxide (N
2O) quantity discharged, field test result show that the bicarbonate of ammonia of combining nano carbon reduces Nitrous Oxide (N than common bicarbonate of ammonia and urea
2O) quantity discharged is more than 70%.
Bicarbonate of ammonia suppresses denitrification because therefore its soluble in water and decomposes for the nitrogen in the soil behind the maintenance chemical fertilizer application, just must control the ammonia-state nitrogen in the soil effectively.Knownly in bicarbonate of ammonia, add an amount of ammonia stablizer or nitrate reductase inhibitor, can be so that bicarbonate of ammonia has fertilizer efficiency in remaining between longer-term.The ammonia stablizer (or solidifying agent) that is adopted is for example: Dyhard RU 100, dicyclohexyl amine, 2-diethylaminoethanol, benzyl cyanide or glycerine nitrilotriacetic fat etc., the nitrate reductase inhibitor that is adopted, for example: N-methyl-p-nitroaniline, the 2-chloropyridine, 3-acetyl is for chloroaniline, N-Nitrosodimethylamine, Sulphathiazole or Dyhard RU 100 etc.Bicarbonate of ammonia and a certain amount of ammonia stablizer and nitrate reductase inhibitor can form cocrystallization or be mixed into granulo-fertilizer through fully.Preferable compound is Dyhard RU 100 (DCD) in above-mentioned ammonia stablizer and nitrate reductase inhibitor.
DCD is a kind of ammonia stablizer, is again a kind of nitrate reductase inhibitor simultaneously, and its molecular formula is N
4H
4C
2, the white crystals body is slightly soluble in water, ethanol and the ammonia solution, and itself is a kind of slow nitrogenous fertilizer, can resolve into guanidine urine and urea at last with the water reaction, and is harmless to soil and plant.Add DCD in bicarbonate of ammonia, can directly reduce bicarbonate of ammonia volatilization loss, it reduces volatile quantity and reaches 52%, can increase soil again to NH
4 +The effect of ionic absorption solidification, it increases NH
4 +Ionic absorption fixed amount reaches 64%.NH in the soil
4 +Ion and carbanion (HCO
3 -) be mutual equilibrated, primary amino and secondary amino group are arranged in the structure of DCD, by the adsorption by hydrogen bond effect of primary amino and secondary amino group, can hold free NH
4 +Ion, thus bicarbonate ion (HCO can be stablized
3 -), play and reduce CO
2The effect of volatilization loss-.Simultaneously because DCD is again a kind of nitrate reductase inhibitor, after ammonium hydrogencarbonate fertilizer adds DCD, the reaction that may make ammonium nitrogen in being manured into soil be converted into nitric nitrogen slows down, promptly reduce the loss of nitrogen in the leaching of nitric nitrogen and the soil that denitrification causes, can reduce chemical fertilizer again underground contaminated water source.The process that ammonium nitrogen changes into nitric nitrogen and nitrite nitrogen can be delayed, and then Nitrous Oxide (N can be reduced
2O) quantity discharged.
Add nano-sized carbon and DCD and obtained the more excellent long-acting fertilizer of performance in the bicarbonate of ammonia chemical fertilizer, can be used as topdresses in early days uses and once does the base manure use before also can changing sowing by topdressing into.Be applicable to that more its nano-sized carbon and DCD additive capacity account for 0.3%~0.5% of long-acting ammonium bicarbonate gross weight in the long-acting ammonium bicarbonate of doing to topdress; And more suitable its additive dosage of long-acting ammonium bicarbonate of making base manure accounts for 0.6%~1.2% of gross weight.
