The preparation method of molten fertilizer.
Background technology
For a long time, the fertilizer used in agricultural production, especially chemical fertilizer, is all for water soluble fertilizer, and water-soluble
Property fertilizer broadly falls into quick-acting fertilizer, particularly carbamide class nitrogenous fertilizer it may be said that in agricultural production increasing both production and income perform meritorious deeds never to be obliterated, but in reality
Border is used middle because being polluted environment by easily causing under the influence of the performance of product own and ambient temperature and humidity.
Nitrogenous fertilizer is the chemical fertilizer containing crop alimentary elemental nitrogen, and elemental nitrogen plays very important effect to plant growth, it
It is amino acid whose ingredient in plant, is the composition constituting protein, be also that plant carries out photosynthesis and plays a decisive role
Chlorophyllous ingredient.Nitrogen can also help crop to divide to grow.Applied nitrogen can not only improve the yield of agricultural product, moreover it is possible to improves
The quality of agricultural product.But, in practical operation, people are in order to increase grain yield and simple raising fertilizer amount is necessarily led
The problem causing excessive fertilization, excessive fertilization can cause some harmful consequences.
Summary of the invention
The present invention is directed to prior art not enough, it is provided that the preparation method of a kind of holding water and fixing nitrogen slow release water-soluble fertilizer.In order to reach
To above-mentioned purpose, the technical scheme is that
The preparation method of a kind of holding water and fixing nitrogen slow release water-soluble fertilizer, comprises the following steps:
(1) by preliminary for the stirring of nitrogenous fertilizer, macromolecular material, water-retaining agent and inserts mixing, fertilizer mixture a is obtained；
(2) fertilizer mixture a is added continuation stirring mixing in solid-liquid blender, under conditions of control stir speed (S.S.) is constant
Add water and auxiliary agent is tentatively mediated, prepare half-dried powder and granule shape material b；
(3) half-dried powder and granule shape material b is joined in extruding kneader, add water and again mediate, make pureed
Thing c；
(4) carrying out pelletize in purees c is continuously introduced into prilling granulator, prepared granule, through dry, sub-sieve, is packed
To holding water and fixing nitrogen slow release water-soluble fertilizer finished product d.
As preferably, the parts by weight composition of each raw material is as follows: nitrogenous fertilizer 5-50 part, macromolecular material 0.001-10 part, protects
Water preparation 0.001-10 part, inserts 20-98 part, auxiliary agent 1-5 part.
As preferably, the quality adding water in described step (2) accounts for the 10-15% of fertilizer mixture a mass, described step
(3) quality adding water in accounts for the 35-55% of half-dried powder and granule shape material b mass.
As preferably, in described step (1), the stir speed (S.S.) of preliminary mixing is that 100-300 turns/min, and mixing time is 5-
15min。
As preferably, in described step (2), stir speed (S.S.) is that 300-500 turns/min.
As preferably, described macromolecular material is polyacrylamide anion or polyacrylamide cation.
As preferably, described water-retaining agent is for selecting starch grafted acrylate polymerization crosslinking thing or acrylamide, propylene salt altogether
Poly-cross-linking agent.
