Abstract
The present invention relates to a kind of synergy fertilizer and preparation method thereof, which is characterized in that contains nitrification inhibitor and metronidazole.The present invention can be further improved slow release effect, extend fertilizer efficiency, improve utilization rate of fertilizer.
Description
Technical field
The present invention relates to a kind of synergy fertilizer and preparation method thereof.
Background technique
China's grain yield accounts for the 16% of the world, and fertilizer amount accounts for 31%, and per hectare dosage is 4 times of world's average dose,
Wherein utilization rate of nitrogen fertilizer is 30% or so, currently in order to improving there are two ways to utilization rate of nitrogen fertilizer uses, one is use coating
Agent carries out coating to fertilizer and achievees the purpose that sustained release in a manner of package, is greatly represented with Nintaus；One kind presses down for nitrification is added
Preparation, by inhibiting NH4 +To NO3 -Conversion, to achieve the purpose that sustained release, using German BASF product En Taike as representative.
For coating agent mainly using resin and sulphur as raw material, there is degradation difficulty and acidification soil in the coating agent of resin and sulphur
The problem of earth；Although nitrification inhibitor can inhibit NH4 +To NO3 -Conversion, specially NH4 ++1.5O2—NO2 -+H2O+2H-, NO2 -
+0.5O2-- NO3 -；However soil acidification is hardened serious at present, the state of anoxic is in soil for a long time, under conditions of anaerobism
Anaerobic bacteria will do it denitrification, by NO3 -It is converted into N2Also nitrogen can be made to cause damages, specially NO2 -+ 3H(electronics donor-
Organic matter) -- 0.5N2+H2O+OH-；NO3 -+ 5H(electronics donor-organic matter) -- 0.5N2+2H2O+OH-, therefore, soil at present
Although nitrification inhibitor is added in situation, still there is also the losses of nitrogen, cause the waste of nutrient.
Meanwhile sulfatereducting bacteria can be by H in hardened soil2SO4It is reduced to H2S, H2S again can be by part beneficial to micro
Element and moderate-element are fixed, and so as to cause hunger sign in plant, such as bitter pit, cause crop failure, reduction reaction is
C6H12O2+3H2SO4—6CO2+6H2O+H2S；S2-+Ca2+--- CaS(precipitating).
At present there has been no on the basis of nitrification inhibitor product, nitrogen discharge is further prevented, utilization rate of fertilizer is improved
Product, also without improving the product in hardened soil beneficial to middle microelement utilization rate.
Summary of the invention
The present invention provides a kind of synergy fertilizer and preparation method thereof, and solving technical problem is 1) in the base of nitrification inhibitor product
On plinth, nitrogen discharge is further prevented, improves utilization rate of fertilizer；2) it improves beneficial to utilization of the middle microelement in hardened soil
Rate.
In order to solve the above-mentioned technical problem, the invention adopts the following technical scheme:
A kind of synergy fertilizer, contains nitrification inhibitor and metronidazole.
The preparation method of synergy fertilizer, nitrification inhibitor and metronidazole are added in fertilizer to get enhanced fertilizer.
The mass ratio of nitrification inhibitor, metronidazole and fertilizer is 0.1~1:0.1~1:98~99.8.
Described be added in fertilizer includes being added in fertilizer slurry after mixing, carries out whitewashing or high-tower granulation；It is added to
It carries out squeezing in fertilizer material or roller is granulated；It is added in fertilizer material and mixes；It is added in liquid fertilizer and mixes.
Invention has following advantageous effects:
1. the present invention can further prevent nitrogen discharge, utilization rate of fertilizer is improved.
2. the utilization rate that middle microelement in hardened soil can be improved in the present invention.
