Abstract
The invention relates to a novel high-efficiency granulated fertilizer which comprises the raw materials based on weight percentage as follows: 78%-82% of urea, 16%-20% of monopotassium phosphate, 0.01%-0.05% of microelements such as boron, ferru, zinc and copper and 1%-2% of additive, wherein the additive is a mixture formed by compound sodium nitrophenolate, DA-6 and brassin. The fertilizer has a high use ratio and small applying quantity, can improve the yield and the quality of agricultural products, and is worth being popularized and used.
Description
Technical field
The invention belongs to the agrochemical field, be specifically related to a kind of high-efficient granule fertilizer that is applicable to corn and Plantula Brassicae chinensis.
Background technology
At present, agricultural enters modernized period, and developing modern agriculture must be equipped modern agriculture with the agricultural material product in modern times.China is large agricultural country, and enriching fertilizer is important measures that guarantee increases in grain production, and development new high-efficiency fertilizer product is to ensure the concrete action that realizes agricultural modernization, is an important step that guarantees national Sustainable Agricultural volume increase, agricultural product quality and safety.The contained nutritive element of conventional composite chemical fertilizer in the market is less, can not satisfy the needs of plant growth fully, and price is higher, effect of increasing production is not obvious, there are in addition the problems such as utilization rate of fertilizer is low, applied amount too much (measure with one mu of corn, every mu of need of existing fertilizer apply about 50kg on the employing market).
Summary of the invention
The object of the present invention is to provide a kind of high-efficient granule fertilizer that is applicable to corn and Plantula Brassicae chinensis, this fertilizer production cost is lower, and applied amount is few, can significantly improve output and the quality of agricultural-food.
The present invention also provides the preparation method of this granulated fertilizer.
For achieving the above object, the present invention adopts following technical scheme:
A kind of high-efficient granule fertilizer that is applicable to corn and Plantula Brassicae chinensis, its raw material by following weight per-cent forms: urea 78～82%, potassium primary phosphate 16～20%, micronutrient boron, iron, zinc and copper 0.01～0.05%, additive 1～2%.
The mixture that described additive preferably is comprised of sodium nitrophenolate, DA-6 and rapin.DA-6 another name: the bright fat of amine, hexanoic acid diethylaminoethanol fat etc.
Concrete, the weight ratio of described sodium nitrophenolate, DA-6 and rapin is preferably 1:1～3:1～2.
The weight ratio of described micronutrient boron, iron, zinc and copper is advisable with 1:5～8:2～4:1～2.
The effect of each proportioning raw material of fertilizer of the present invention is as follows: urea provides nitrogen element source, is the chief component of this fertilizer; Potassium primary phosphate provides phosphorus, potassium element source; Trace element provides the source of boron, iron, zinc, copper; Additive is used to provide the required conditioning agent of plant growth.Among the present invention, micronutrient boron, iron, zinc, copper come from respectively compound borax, ferrous sulfate, zinc sulfate and copper sulfate.
Above-mentioned Novel high-efficiency granulated fertilizer can adopt routine techniques to be prepared: change over to after each raw material is mixed in proportion and stir (to guarantee the raw material even blend) more than 5 minutes in the blending machine; then the good material of blending is poured into the melting tank and carry out melting (melting utilize fuel gas hot-blast stove to add warm air directly carry out melting to admixing good material); the material of melting changes the centrifugal granulator machine over to again and granulates (under wind effect; granular material is naturally cooling in the decline process); particle after the discharging is sieved; sieve underproof product and send the again melting of melting operation back to; sieve qualified particle and carry out metering packing, the end product warehouse-in.This technical process is non-wastewater discharge in process of production, and hot-air filter is discharged a small amount of nontoxic powder, and recoverable is little to environmental influence.When the fertilizer finished product is transported to packaging process, take totally-enclosed system, in case product is contaminated.The fertilizer that makes is particulate state, uses it for agriculture production, can play the raising chemical fertilizer utilization ratio, improves the output of farm crop, improves the effect of agricultural product quality.
Granulated fertilizer of the present invention is mainly used in field crop, and as topdressing, applied amount is generally 20～25kg/ mu.In addition, because this fertilizer is full water-soluble, so can also be used for vegetables, fruit tree etc. in the mode that sprays, consumption is 20～30kg/ time 300 times the aqueous solution.
Be compared with existing technology advantage of the present invention:
Each raw material rational proportion is made fertilizer of the present invention, and utilization rate of fertilizer is high, applied amount few (measure with one mu of corn, adopt every mu in fertilizer of the present invention only need apply about 25kg), thus reduced the planting cost of crop.In addition, output and quality that fertilizer of the present invention can the Effective Raise agricultural-food are worthy of popularization.
Description of drawings
Fig. 1 is the production technological process of granulated fertilizer of the present invention.
Embodiment
The present invention is described in detail by the following examples, but protection scope of the present invention is not limited to this.
Embodiment 1
