Abstract
The invention belongs to a preparation method of a compound fertilizer. The method comprises the following steps: fully grinding fulvic acid powder, ammonium nitrate, dipotassium hydrogen phosphate, potassium sulfate, magnesium sulfate, brassinolide and additives, mixing above materials in proportion, blending, granulating the obtained mixture, and cooling the granulated mixture. The compound fertilizer can effectively increase the yield of crops, improves the disease resistance and the stress resistance of the cops, and avoids the problems of nutrition element proportion imbalance and soil nutrition structure change.
Description
Technical field
The present invention relates to a kind of complex fertilizer and preparation method thereof, particularly relate to the complex fertilizer containing fulvic acid powder。
Background technology
Fulvic acid (FulvicAcids, code name FA) complex mixture of the mainly class macromole fragrant-aliphatic series hydroxy carboxylic acid containing active function groups, coal (weathered coal, brown coal) FA that originates is nearly all organic carboxyl acid (with aromatic proton for construction unit), and soil, peat, the FA in the sources such as biomass of rotting is except organic carboxyl acid, also containing protein more or less, carbohydrate, lipid material, aminoacid and nucleic acid etc., but all FA combine a certain amount of inorganic substances (metal ion, salt, clay mineral etc.), the nitrogen that fulvic acid itself is contained, phosphorus, potassium is little, purity can reach more than 95%, use mainly as plant growth promoter, dynamical fertilizer can be made by nutrition compositions such as the big medium trace element of addition。
Complex fertilizer is the conventional fertilizer of the one in modern agricultural production, wherein contain at least two in nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and effective content namely to think in complex fertilizer containing this kind of fertilizer no less than the 4% of complex fertilizer gross mass, raising along with farm output, the phenomenon of soil nutritional deficiency is more and more obvious, and the consumption that makes of complex fertilizer is also being gradually increased。
The effect of increasing production of current existing complex fertilizer has much room for improvement。
Summary of the invention
The present invention provides a kind of complex fertilizer, and has good effect of increasing production。
For reaching described purpose, the present invention adopts the following technical scheme that
A kind of complex fertilizer consisted of the following composition:
Fulvic acid powder mass fraction 40%-50%；
Ammonium nitrate mass fraction 15%-20%；
Dipotassium hydrogen phosphate mass fraction 10%-20%；
Potassium sulfate mass fraction 5%-10%；
Magnesium sulfate mass fraction 10%-15%；
Study on brassinolide mass fraction 1%-5%；
Additive: surplus。
The method that the present invention also provides for preparing the complex fertilizer with good effect of increasing production。
A kind of method preparing complex fertilizer includes:
Fulvic acid powder is fully ground；
Ammonium nitrate, dipotassium hydrogen phosphate, potassium sulfate, magnesium sulfate, study on brassinolide are fully ground；
Raw material after grinding is mixed uniformly with additive, wherein fulvic acid powder mass fraction 40%-50%, ammonium nitrate mass fraction 15%-20%, dipotassium hydrogen phosphate mass fraction 10%-20%, potassium sulfate mass fraction 5%-10%, magnesium sulfate mass fraction 10%-15%, study on brassinolide mass fraction 1%-5%, additive is surplus；
Mixture pelleting after mixing；
Gained granule is cooled down。
The complex fertilizer of the present invention can make crop effectively increase production。The method preparing complex fertilizer of the present invention can obtain the complex fertilizer with good effect of increasing production。
The invention has the beneficial effects as follows and crop can be made effectively to increase production, and also can improve the disease-resistant anti-adversity ability of crop, additionally, owing to the complex fertilizer of the present invention uses fulvic acid powder to be raw material, therefore the problem that the industrial chemicals cost used by existing complex fertilizer is high, price is unstable can be solved, reduce the cost of complex fertilizer。
Below complex fertilizer of the present invention and preparation method thereof is described in detail。
A kind of complex fertilizer consisted of the following composition:
Fulvic acid powder mass fraction 40%-50%；
Ammonium nitrate mass fraction 15%-20%；
Dipotassium hydrogen phosphate mass fraction 10%-20%；
Potassium sulfate mass fraction 5%-10%；
Magnesium sulfate mass fraction 10%-15%；
Study on brassinolide mass fraction 1%-5%；
Additive: surplus, can be the conventional additives in the complex fertilizers such as binding agent, anticaking agent, inserts。
Fulvic acid powder, ammonium nitrate, dipotassium hydrogen phosphate, potassium sulfate, magnesium sulfate, study on brassinolide and additive are mixed according to proportioning, pelletize screening after stirring。
