Description
Technical field
The present invention relates to a kind of composition, synergist and its preparation side in particular to a kind of compound/complex fertilizer
Method and application method.
Background technology
Chemical fertilizer plays an important roll in agricultural production, is conducive to the good harvest and volume increase of crops.Conventional chemical fertilizer has nitrogen
Fertilizer, phosphate fertilizer and potash fertilizer etc..In order to increase fertilizer efficiency and save cost, often a variety of Fertilizer Combinations are used, be prepared into compound fertilizer or
Complex fertilizer.Chemical fertilizer is used merely, manure digestion fast, the fertile phase is there is short（Only several weeks）Deficiency, it is impossible to meet agriculture
Need of the plant growth about more than the 100 day fertile phase, if frequently applied fertilizer to extend fertilizer efficiency, not only substantially increase production cost is made
Into waste, excessive accumulation can also cause pressure of degrading to the catabolite of fertilizer to environment in the environment, cause environmental pollution.In order to
This problem is avoided, present many fertilizer are often with fertilizer synergist with using, and these fertilizer synergists can make fertilizer efficiency slow
Release, always with the growth period of crop, not only reduces the access times of chemical fertilizer, also effectively protects environment.But it is existing
Easily decomposed at high temperature when synergist is used, reduce efficiency.
The content of the invention
It is an object of the present invention to provide a kind of synergist of compound/complex fertilizer, the synergist can not only be effective
Extend fertilizer efficiency, increase operation rate, more can fully be echoed with fertiliser granulates without being lost or causing chemical fertilizer granule adhesion, Er Qiecao
Make simple, beneficial to popularization.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of fertilizer synergist, it includes the material powder that following weight is matched：Normal-butyl thiophosphoryl triamine 20 ~ 30
Part, 5 ~ 200 parts of 1- first carbamyl -3- methylpyrazoles, 100 ~ 10000 parts of ammonium humate, the fineness 400 ~ 800 of the material powder
Mesh.
It is preferred that, in above-mentioned technical proposal, 25 parts of normal-butyl thiophosphoryl triamine, 1- first carbamyl -3- methylpyrazoles
30 parts, 300 parts of ammonium humate.
The preparation method of the synergist is：By normal-butyl thiophosphoryl triamine, 1- first carbamyl -3- methylpyrazoles, rotten plant
Sour ammonium is ground into the powder of the fineness through airslide disintegrating mill, is then formed by the weight proportion is well mixed.
It is a further object to provide a kind of application method of above-mentioned synergist, the application method is by the fertilizer
Expect synergist and nitrogenous compound fertilizer or complex fertilizer particle is mixed so that fertilizer synergist is attracted to containing nitrogen composite fertilizer
The weight ratio of the surface of material or complex fertilizer particle, the fertilizer synergist and nitrogenous compound fertilizer or complex fertilizer particle is 1:
10 ~ 1000, nitrogenous compound fertilizer or the complex fertilizer particle diameter is not more than 3 millimeters.
In above-mentioned nitrogenous compound fertilizer or complex fertilizer in addition to containing nitrogen, typically also containing P elements, potassium element etc.,
To commonly use fertilizer.When preparing nitrogenous compound or complex fertilizer, preferred urea, can also select ammonium sulfate, ammonium nitrate, ammonium chloride etc. with
Urea collocation is used as nitrogenous fertilizer, phosphate fertilizer multiselect MAP, Diammonium phosphate (DAP), potash fertilizer multiselect potassium chloride, potassium sulfate etc..
The beneficial effects of the invention are as follows：From two kinds of normal-butyl thiophosphoryl triamine and 1- first carbamyl -3- methylpyrazoles
Component, can enable fertilizer slowly discharge, and improve nitrogen plant recovery of nutrient, extend fertilizer efficiency period, while taking full advantage of just
The structure of NBPT and 1- first carbamyl -3- two kinds of molecules of methylpyrazole has more highly polar or even can form hydrogen
The characteristics of key, make itself and addition ionic compound ammonium humate carry out it is stronger attract each other, and hold under specific fineness
Solid absorption is easily carried out by the surface of nitrogenous compound fertilizer or complex fertilizer particle, so that uniform in one layer of particle surface formation
Clad, can thus be echoed with fertilizer together with use.During making, being crushed using airslide disintegrating mill can avoid in processing
During the rise of common mechanical pulverizer easy temperature and cause loss of material, can be simultaneously reached common mechanical pulverizer and be difficult to reach
The fineness requirement arrived.Using this synergist, it is not required to add in high-temperature baking pelletization stage, also without the use of organic solvent, simply
It is that can reach the purpose that absorption is wrapped up that particle and synergist are carried out into mechanical mixture, extremely easy to use.On increasing in the present invention
Imitate agent fineness restriction, and the weight proportion and particle diameter used with particle restriction, be all very crucial, this can
Ensure that synergist consumption is suitable, more can guarantee that synergist wraps up effect to particle, so that the overall use effect of fertilizer is effectively ensured
Really.Not only hold easy dusting, and one layer of very few mistake being wrapped in outside particle if synergist fineness is too small, in production process
It is thin, do not reach due dosage, the fineness of synergist is excessive, then increase absorption difficulty, it is more difficult to be attracted to particle surface, if
The diameter of nitrogenous compound fertilizer or complex fertilizer particle is excessive, then one layer adsorbed is still relatively excessively thin, it is impossible to which satisfaction uses needs.
In addition, ammonium humate also has the activation to phosphate fertilizer and potash fertilizer.
