Description

High nitrogen type water-soluble fertilizer containing fulvic acid
Technical field
The present invention relates to a kind of full nutritive element water-soluble fertilizer containing fulvic acid, belongs to agricultural fertilizer technical field.
Background technology
As the development of chemical industry, the consumption of chemical fertilizer increase sharply, its life-time service generates very big shadow to soil Ring, the part for utilizing absorbed by crops also only accounts for the 30%-40% of sowing amount, and remaining is present in soil, contaminated soil, shadow Agricultural ecological is rung, when serious, even the salinization of soil is directly resulted in.Plus for a long time, Planting household applies N, P, K a great number of elements partially Fertilizer, ignores the supplement of middle trace element, causes the nutritional labeling in soil unbalance so that plant effectively cannot absorb. While planting cost is greatly increased, income does not but effectively improve.With the development of high-efficiency agriculture in recent years, sprinkling irrigation, The application of drip irrigation technique, more and more extensive therefore new, the unique full nutrition unit of high-load, complete water-soluble Fertilizer application Plain water-soluble fertilizer research and development are very urgent.
In recent years, increasing enterprise participates in the research and development of water soluble fertilizer and produces with mechanism, production technology It is similar with the selection of raw material.Using primary raw material have carbamide, ammonium sulfate, ammonium chloride, MAP, Diammonium phosphate (DAP), Potassium dihydrogen phosphate, magnesium potassium sulfate, water soluble organic substance and middle trace element etc., these raw materials through pulverization process, according to certain Ratio mix homogeneously makes corresponding water soluble fertilizer.
The water-soluble fertilizer product of prior art mixture is primarily present following problem:(1) outward appearance is bad.Be mainly reflected in color and luster, In the discordance of granularity.(2) product high humidity, causes caking, impact to use and sell.
In recent years, biochemical fertilizer is gradually valued by the people with its unique growth-promoting effect.Wherein fulvic acid is with plant Growth regulating, drought resisting are projected against growth, are particularly taken seriously.Traditional fulvic acid is extracted from low-grade coal , also there is the biochemical fulvic acid obtained through biofermentation.But the easy moisture absorption of fulvic acid itself, is simply added to water-soluble fertilizer In, easily there is the problems such as mixing inequality, high humidity, in the case that chemical fertilizer storage condition is not good, even more easily occur a large amount of Caking, has a strong impact on the use of chemical fertilizer.
Chinese patent CN102351604A discloses a kind of Fulvic acid organic fertilizer material, it include nitrogen 3%~7%, phosphorus 3%~ 7%th, potassium 3%~7%, aminoacid 8%~12%, organic matter 25%~35%, fulvic acid 15%~25% and plant growing is adjusted Section agent 4%~6%.Containing active very strong organic component, microorganism growth can be greatly promoted, promote plant growing.But Substantial amounts of aminoacid, organic matter and fulvic acid are wherein used, is extremely easily made moist, back plate of making moist is formed block and is difficult with.And And, as the fulvic acid addition for wherein using is very big, after fertilising, fulvic acid utilization rate is not high, and microorganism growth excessively goes back shadow Oxygen content in soil is rung, is unfavorable for plant growing on the contrary.
Chinese patent CN102381922A discloses a kind of potassium fulvate fertilizer, and it includes:Nitrogen 10%~15%, biological clamps 2%~6%, aminoacid 0.5%~3%, Organic substance 25%~35%, fulvic acid 10%~15%, trace element 11%~ 15%th, rare earth 3%~6%, swelling agent 0.1%~2%, vegetable protein 0.1%~2% and chitin 0.1%~3%.Its energy Enough promote plant stalk healthy and strong, improve fruit quality, strengthen plant cold tolerance, but equally exist hygroscopic component content mistake Big problem, it is difficult to long-term to preserve.And after applying fertilizer, microorganism easily occur and excessively increase sharply, plant growing is affected, fulvic acid is reduced The problem of utilization rate.
In addition, existing chemical fertilizer mostly is single fertilizer, even a few nutrient is generally also only contained in compound fertilizer, and Indivedual micronutrient levelss it is low even without.Especially water soluble fertilizer product, more than 90% is only nitrogenous, phosphorus, potassium and part are micro- To for water-soluble chemical fertilizer, secondary element, requires that high drip irrigation agricultural production causes serious restriction.
The content of the invention
It is an object of the invention to overcome in prior art chemical fertilizer nutrient easily not occur inhaling in complete, fulvic acid application A kind of deficiency of wet caking, there is provided full nutritive element water-soluble fertilizer containing fulvic acid.Overcome water-soluble fertilizer element in prior art Incomplete, application effect is not good, the defect or deficiency of fulvic acid chemical fertilizer easily caking.
In order to realize foregoing invention purpose, the invention provides technical scheme below:
A kind of high nitrogen type water-soluble fertilizer containing fulvic acid, it includes the element or composition of following weight percent:Nitrogen 25%-35%, phosphorus 5%-15%, potassium 5%-15%, zinc 0.01%-0.3%, boron 0.01%-0.3%, magnesium 0.01%-0.3%, Manganese 0.01%-0.3%, ferrum 0.01%-0.3%, fulvic acid 0.5%-2%.
It is preferred that nitrogen 28-32%, phosphorus 7%-12%, potassium 7-12%, zinc 0.01%-0.1%, boron 0.01%-0.1%, magnesium 0.01%-0.1%, manganese 0.01%-0.1%, ferrum 0.01%-0.1%, fulvic acid 1%-1.5%.
Further, the nitrogen with:The form addition of one or more compoundings in carbamide, MAP and potassium nitrate In fertilizer.
Further, the P elements are added in fertilizer in the form of potassium dihydrogen phosphate and/or MAP.
Further, the potassium element is with the shape of any one or a few compounding in potassium nitrate, potassium dihydrogen phosphate and potassium sulfate In formula addition fertilizer.
Further, the trace element zinc, boron, magnesium, manganese, ferrum respectively with:Zinc sulfate, Borax, magnesium sulfate, manganese sulfate, sulfur The form of sour ferrum is added in fertilizer.
Further, the high nitrogen type water-soluble fertilizer containing fulvic acid, it is made up of the composition of following weight percent 's:Carbamide 60-70 parts, potassium nitrate 0-19 parts, MAP 9-26 parts, potassium dihydrogen phosphate 10-27 parts, potassium sulfate 0-10 parts.It is excellent Select carbamide 62-64 parts, MAP 20-24 parts, potassium dihydrogen phosphate 10-12 parts, potassium sulfate 8-10 parts.
Present invention also offers a kind of method for preparing above-mentioned chemical fertilizer, it comprises the following steps:
(1) part weighs raw material by weight proportion, is placed in Sealing Arrangement and mixes;
(2) raw material of mix homogeneously is crushed in air drying type disintegrating apparatus;
(3) by subpackage in the raw material drying environment after crushing, (air Jing dehumidification treatments, humidity had both obtained finished product less than 20%) Chemical fertilizer.
Compared with prior art, beneficial effects of the present invention:
The water-soluble chemical fertilizer of high nitrogen type containing fulvic acid of the present invention, comprehensive nutrition are balanced, meet needed for plant growing, wherein containing There is appropriate fulvic acid, the absorption nutritional labeling of plant can be effectively promoted, quickly grown vigorously.And the present invention's is water-soluble In chemical fertilizer, each component can be mutually coordinated, not there is a problem of that local moisture absorption is too strong, effectively solve chemical fertilizer after being uniformly dispersed Easy moisture absorption caking, the problem for affecting to use during storage.
