Description
Technical field
The present invention relates to the technical field of fertilizer that a kind of technical field of chemical fertilizer more particularly to microbial bacterial agent height are survived.
Background technology
Microbial manure applies the history for agriculturally having nearly half a century in China.It is micro- from nitragin-bacterial fertilizer-
Bio-feritlizer, although the microbial manure in China gradually develops, fertilizer efficiency is unstable, and bacterium survival rate in storage, soil is low,
Cause fertilizer to the ineffective of crop yield.
Invention content
The purpose of the present invention is to provide a kind of high nutrient chemical fertilizer and preparation method thereof of agricultural microbial agent height survival,
To solve the problems, such as that bacterial manure is ineffective in the prior art.
The present invention adopts the following technical scheme that in order to achieve the above object：
A kind of high nutrient chemical fertilizer of agricultural microbial agent height survival, by weight, including following component：Urea 25-
30 parts, 10-20 parts of monoammonium phosphate, 20-35 parts, 20-35 parts glues of potassium sulfate, 15-20 parts of EM bacterium powders, peroxidating calcium powder 10-15
Part, 25-30 parts of waterglass, 40-60 parts of oligomeric methyl silanol potassium solution.
Further, the mass concentration of the glue is 3-5%.
Further, the glue includes gelatin and polyvinyl alcohol.
Further, the mass concentration of the oligomeric methyl silanol potassium solution is 50-60%.
A kind of preparation method of the high nutrient chemical fertilizer of agricultural microbial agent height survival, steps are as follows：
(1) urea, monoammonium phosphate, potassium sulfate are mixed into chemical fertilizer, are then added and account for material total weight 1/5-3/8's
Water makes part chemical fertilizer dissolve, and a part of glue is added in heating, stir in addition, stops stirring, use when residual moisture 10%
Granulating disc is granulated, and obtains granulated fertilizer；
(2) granulated fertilizer is added in granulating disc, when granulating disc rotates, sprays into remaining glue, keep glue equal
The even surface for being distributed in granulated fertilizer is remained without remaining glue；
(3) EM bacterium powders and peroxidating calcium powder are mixed, is then sprayed on granulated fertilizer surface, granulating disc continues to rotate
Granulated fertilizer is set uniformly to be coated；
(4) granulated fertilizer into the granulating disc of rotation sprays into waterglass again, keeps granulated fertilizer uniform by waterglass
Cladding；
(5) oligomeric methyl silanol potassium is prepared aqueous solution, it is past in the granulated fertilizer input coating machine that step (4) is obtained
Oligomeric methyl silanol aqueous solutions of potassium, sprayed soak are sprayed in granulated fertilizer.
Preferably, the glue being added into chemical fertilizer in the step (1) accounts for glue weight 2/3.
Preferably, the temperature kept the temperature in the step (5) is 130 DEG C -140 DEG C.
The invention has the advantages that：First, microbial inoculum is protected in coating layer by layer, can well be survived in fertilizer；Organosilicon
Polymer forms hydrophobic permeable membrane on granulated fertilizer surface, and the steam in soil reaches waterglass layer, water by hydrophobic permeable membrane
Glassy layer water swelling, the water that waterglass layer is inhaled is more and more, and calper calcium peroxide absorbs water release oxygen from waterglass layer, swollen
Swollen waterglass layer is burst, while EM bacterium obtain sufficient oxygen and moisture and can breed rapidly, are gradually discharged from granulated fertilizer；
The also gradually release in the soil of the chemical fertilizer of core, keeps fertilizer efficiency for a long time.
