Abstract
The invention relates to a fertilizer, more specifically relates to a composite fertilizer and a preparation method thereof, and belongs to the technical field of chemicals. The composite fertilizer comprises urea, calcium superphosphate, calcium magnesium phosphate fertilizer, potassium chloride and ammonium sulfate, and is prepared by adding trace elements into the raw materials, crushing, weighing and mixing, granulating, drying and screening. Therefore, the prepared composite fertilizer product not only has correct chemical compositions, but also has excellent physical properties, and is convenient for peasants to use.
Description
Technical field
The present invention relates to a kind of chemical fertilizer, be specifically related to a kind of composite fertilizer and preparation method thereof, belong to chemical technology field.
Background technology
Farm crop through the production of certain period until maturation, can output than the fruit of thousand times of its original seed tuples, must be from soil or a large amount of nutrition of surrounding environment absorption, this nutrition mainly includes machine nutrition and inorganic nutrients two big classes.What wherein requirement was maximum is chlorine (N), phosphorus (P), potassium (K).Because the growth needs of the content far away not enough plant of this three major types element in soil is additional by applying fertilizer usually, satisfies the needs of plant-growth, thereby reaches the purpose of increasing both production and income.Except nitrogen, phosphorus, potassium three big elements, owing to cultivate crop for a long time, other element in soil also gradually reduces, be difficult to satisfy the needs of plant-growth, these elements mainly contain zinc (Zn), boron (B), manganese (Mn), molybdenum (Mo), iron (Fe), sulphur (s), calcium (Ga), magnesium (Mg), titanium (Ti), ((21), aluminium (AI), sodium (Na), copper (Cu), barium (Ba), strontium (Sr), cobalt (GO), nickel (Ni), vanadium (v) wait oxygen.More than the content of various elements in plant be different with requirement, it also is not quite similar to plant-growth effect and form.Accomplish increasing both production and income, what need suit according to the situation of soil element is additional, and this mainly adopts the method for fertilising, lacks what nutrient and mends what nutrient, how much lacks how many benefits.And lack on the market can be widely used in farm crop contain the trace element composite fertilizer.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of composite fertilizer and preparation method thereof is provided, this composite fertilizer includes urea, calcium superphosphate, fused(calcium magnesium)phosphate, Repone K, vitriolate of tartar, ammonium sulfate, be equipped with trace element through raw material pulverizing, weighing mixing, granulation, drying, screening, etc. step made, the feasible existing correct chemical constitution of producing of complex fertilizer product, good physical behavior is arranged again, be convenient to peasant household and use.
The present invention realizes with following technical scheme: a kind of composite fertilizer, it is characterized in that: composite fertilizer includes urea, calcium superphosphate, fused(calcium magnesium)phosphate, Repone K, vitriolate of tartar, ammonium sulfate, it is made to be equipped with trace element, the weight part of above-mentioned each raw material is: urea 40-45 part, 10 parts of calcium superphosphate, 3 parts in 12 parts in fused(calcium magnesium)phosphate, 20 parts in Repone K, vitriolate of tartar 5-7 part, ammonium sulfate, 3 parts of trace elements.
Described trace element is: wherein one or more of boron, zinc, manganese, copper, iron, molybdenum.
A kind of method for preparing composite fertilizer is characterized in that: this method comprises that raw material pulverizing, weighing mixing, granulation, drying, screening, finished product carry out as follows:
(1) raw material is crushed to granularity less than 1mm through pulverizer;
(2) raw material weighing of step (1) is mixed;
(3) the mixed material of step (2) is sent in the tablets press, added an amount of tackiness agent and carry out granulation;
(4) material after the granulation carries out drying;
(5) dried granular complex fertilizer is transported to the double deck screen screening, and tiny granular and pulverulent material then returns granulating working procedure granulation again;
(6) direct bulk storage of finished product after screening or packing warehouse-in.
Advantage of the present invention is: this composite fertilizer's prescription rationally can satisfy the growth needs of farm crop, and complete processing is simple, when producing composite fertilizer special, according to the crop growth needs, can add Insecticides (tech) ﹠ Herbicides (tech) etc. therein.After using this composite fertilizer, can effectively improve Soil structure, increasing crop yield is increased income.
The invention will be further described below in conjunction with embodiment;
