Abstract
The invention relates to a formula and a preparation method of slow release fertilizer special for coastal wetlands, and relates to the field of fertilizers. The formula includes 1.0-2.5% of liquid ammonia, 2-5% of dilute acid, 10-20% of urea, 20-45% of mono-ammonium phosphate, 5-12.5% of potassium sulfate, 3-7.5% of ammonium sulphate, 1-3% of slow release agent, 1-2% of envelop, and 1.0-2.5% of bentonite. The preparation method includes: adding materials; using a grinder to grind the materials; using a mixer to mix the materials; using a granulator to granulate the materials; measuring pH value and blending dilute acid; using a drying kiln for drying (kiln head temperature is 180-200 DEG C, and kiln end temperature is controlled at 40-80 DEG C); using a cooling kiln for cooling; screening; adding the slow release agent by spraying; and enveloping at 100 DEG C by high-temperature oil jet to obtain finished products. The slow release fertilizer can be used to improve alkaline soil and promote soil acid-base balance, and accordingly the slow release fertilizer is widely applicable to coastal wetlands.
Description
Technical field:
The present invention relates to the chemical fertilizer field, be specifically related to coastal wetland special slow release fertilizer formula and preparation method thereof.
Background technology:
The soil of coastal wetland is alkalescence, and moisture is sufficient, and nutrient runs off easily; And the general growth cycle of coastal plant is longer, so when using general fertilizers, the salinity of fertilizer own is higher; Aggravate the alkalization of soil property, added violent, the weak point of fertilizer efficiency, be unfavorable for very much the needs of the long term growth of crop.
Summary of the invention:
The purpose of this invention is to provide coastal wetland special slow release fertilizer formula and preparation method thereof; It has combined the needs of coastal wetland alkalescence soil improvement; Use simply, conveniently, with strong points, can improve alkaline soil; Promote soil acid-base equilibrium, long-acting slow-release fertilizer is extensively used on coastal wetland.
In order to solve the existing problem of background technology, the present invention adopts following technical scheme: its prescription consists of: liquefied ammonia 1.0-2.5%, diluted acid 2-5%; Urea 10-20%, monoammonium phosphate 20-45%, vitriolate of tartar 5-12.5%; Sulphur ammonium 3-7.5%; Sustained release dosage 1-3%, coating 1-2%, wilkinite 1.0-2.5%.
Its preparation method is: and raw material feeds intake → and kibbler pulverizing → stirrer stirring → tablets press granulation → measurement pH value+diluted acid mediation → drying kiln oven dry (temperature of kiln head is at 180-200 degree centigrade, and kiln end temperature is controlled at 40-80 degree centigrade) → cooling kiln cooling → screening → spray painting mode adds sustained release dosage → high temperature oil spout mode coating (100 degrees centigrade) → finished product.
The present invention has following beneficial effect: can improve alkaline soil, promote soil acid-base equilibrium, long-acting slow-release fertilizer is extensively used on coastal wetland.
Embodiment:
This embodiment adopts following technical scheme: its prescription consists of: liquefied ammonia 2.5%, diluted acid 5%, urea 20%, monoammonium phosphate 45%, vitriolate of tartar 12.5%, sulphur ammonium 7.5%, sustained release dosage 3%, coating 2%, wilkinite 2.5%.
Its preparation method is: and raw material feeds intake → and kibbler pulverizing → stirrer stirring → tablets press granulation → measurement pH value+diluted acid mediation → drying kiln oven dry (temperature of kiln head is at 180-200 degree centigrade, and kiln end temperature is controlled at 40-80 degree centigrade) → cooling kiln cooling → screening → spray painting mode adds sustained release dosage → high temperature oil spout mode coating (100 degrees centigrade) → finished product.
Described diluted acid is disposed by the certified products vitriol oil (98%).
Described sustained release dosage adopts the tangible chitin of slow release effect, and chitin is nontoxic to have no side effect, and uses anti-hard caking agent sealing wax.
Prescription composition nitrogen element is selected liquefied ammonia (nitrogen content 93%), urea (nitrogen content 46.3%) or sulphur ammonium (nitrogen content 17%) for use among the present invention; Phosphoric is selected Vanadium Pentoxide in FLAKES, like monoammonium phosphate (wherein nitrogen content 11%, phosphorus content 44%); Potassium element is selected vitriolate of tartar (vitriolate of tartar content 50%).Through the sulfate ion in the prescription composition, in conjunction with allocating into of dilute sulphuric acid (acid is dense at 60%-70%), the acid-basicity of regulating product is to slightly acidic, and promptly pH value controls to 5.5-6.0, uses the PH meter to measure and control.
