Description
Technical field
The invention belongs to crop technical field of fertilizers, be specifically related to a kind of nutrition potentiating and anti-caking block composite fertilizer and preparation method thereof.
Background technology
Agricultural modernization is had higher requirement to chemical fertilizer, and its development trend is exactly high concentration, Composite and customizations.At present, composite fertilizer is all being greatly developed in countries in the world, and the ratio that composite fertilizer occupies in the production and consumption of chemical fertilizer is increasing.Some developed countries even can reach 70 ~ 80%, and the Chemical Mixed Fertilizer of China development start late, only account for about 20% at present, therefore develop composite fertilizer be China accelerate agricultural modernization in the urgent need to.So-called composite fertilizer just refers in nitrogen, phosphorus, potassium three kinds of nutrients, has at least the nutrient of two kinds of declarable contents to be the fertilizer be made up of chemical process and (or) mixing method.Product wherein containing two kinds of nutrients is two yuan of Chemical Mixed Fertilizers, and the fertilizer containing three kinds of nutrients is ternary compound fertilizer.In recent years, in common Chemical Mixed Fertilizer, add the fertilizer of some trace elements, be called as multi-element compound fertilizer.In addition, some fertilizer products add agricultural chemicals or growth hormone in traditional Chemical Mixed Fertilizer, are called as multifunction mixed compound fertilizer.In China, composite fertilizer is the general designation of compound manure and mixed fertilizer, conventional kind can be called as respectively change into composite fertilizer, blend together composite fertilizer, fusion is fertile, organic-inorganic compound mixed fertilizer.
At present, the compound fertilizer share of China is about 32%, and physical output is about fifty-five million ton.Composite fertilizer is in production process and in the shelf lives, and easy moisture absorption caking, particle adhesion, decomposition of making moist, make it use uneven, reduces fertilizer efficiency.Large quantity research shows, the plant recovery of nutrient of existing Chemical Mixed Fertilizer is lower, this season utilization ratio about 30% of such as nitrogen, phosphorus this season utilization ratio about 25%, potassium this season utilization ratio about 45%.Therefore, how solving composite fertilizer caking and improving fertilizer nutrient utilization is the focus that people pay close attention to and study all the time.
In recent years, domestic and international raising utilization rate of fertilizer mainly contains following approach: 1) Envelope type Chemical Mixed Fertilizer, coated fertilizer used mainly contains two classes, one is organic high molecular polymer (such as resins polyolefins class), and two is inorganic materials (as sulphur, ground phosphate rock, fused(calcium magnesium)phosphate etc.) of slightly water-soluble or microsolubility.2) urea aldehyde Chemical Mixed Fertilizer, utilizes the feature that urea and formaldehyde can react, and passes into formaldehyde, had the urea aldehyde Chemical Mixed Fertilizer of slow-releasing by rotary drum or high tower explained hereafter in the process of producing Chemical Mixed Fertilizer in urea melting liquid.The Chemical Mixed Fertilizer of above-mentioned production technique is because of complex process, and production cost is high, and production capacity is low, in agriculture production, particularly on field crop, is difficult to large scale application.The inorganic anti-hard caking agent of current interpolation, the mineral filler adopted has diatomite, bentonite sodium, wilkinite calcium, kaolin, zeolite etc., mineral filler is adsorbed on composite fertilizer particle surface, caking is prevented by buffer action, though there is certain effect, but consumption is large, and excessive mineral filler also can cause dust, causes environmental pollution.
Summary of the invention
The object of the invention is to provide a kind of nutrition potentiating and anti-caking block composite fertilizer and preparation method thereof.
For achieving the above object, the present invention adopts following technical scheme:
A kind of nutrition potentiating and anti-caking block composite fertilizer, comprise composite fertilizer, it is also containing DA-6 crude oil, and this DA-6 crude oil is coated on composite fertilizer surface.Wherein, the DA-6 crude oil of preferred purity 98%.
Concrete, the weight content of described DA-6 crude oil is 0.01 0.1% of Chemical Mixed Fertilizer doses.
The preparation method of described nutrition potentiating and anti-caking block composite fertilizer: composite fertilizer and DA-6 crude oil are delivered in proportion packing after stirring in mixing and blending machine.
Product of the present invention is mainly with 50kg/ bag, and the superposition mode of stacking of 15 bag of one buttress is placed in warehouse, can keep loose state about 3 months of not luming.Field using method: mu product 30 40kg of the present invention, bottom application or impose use.
Above-mentioned composite fertilizer can be any one composite fertilizer that market has been bought, as binary compound fertilizer, ternary compound fertilizer, multi-element compound fertilizer etc.
Innovative point of the present invention is to select the DA-6 of 98% crude state to carry out composite composite fertilizer as the agent of nutrition potentiating and anti-caking block.DA-6 is that first American scientist found beginning of the nineties 21 century, and international academic community is praised highly most, has the compound of very high biological activity.Prove that DA-6 is newfound a kind of efficient plant growth material through test both at home and abroad, to multiple kinds of crops, there is significant volume increase, degeneration-resistant, disease-resistant, the effect such as oil recovery enhancement, precocity.DA-6 is nontoxic, have no side effect, noresidue, and better with the consistency of ecotope, this is that other plant growth promoter does not have, and it can be composite with multiple element, can also and bactericide compounded use, strengthen the resistance against diseases of plant, improve sterilization effect; It can strengthen the anti-adversity abilities such as crop cold resistance, drought resisting, waterlogging-resistant, resistant to lodging, disease-resistant, anti-poisoning, more than 8 15% can be increased production, precocious 5 10 days, the content of the nutritive ingredients such as the protein of product, amino acid, VITAMIN, sugar, carotene can be improved, improve the quality of product, make fruit prods painted good, fruit type is attractive in appearance, mouthfeel good, improve commodity, extend the breeding time etc. of vegetables.
Plant-growth regulator DA-6 forms a coating film at composite fertilizer particle surface after mixing with composite fertilizer particle with crude state, prevents the contact between particle, and increases the intensity of fertiliser granulates, thus plays the good result of anti-caking and anti-efflorescence.DA-6 is as a kind of efficient plant growth regulator, and the decomposition rate of tunable nutritive element is consistent with the regulation of fertilizer requirement of crop, removes the antagonistic action between various nutrient elements, facilitates release and crop the absorbing various nutritive element of fertilizer nutrient.
Compared to the prior art, composite fertilizer tool of the present invention has the following advantages:
1) effectively prevent and solve the agglomeration problems of composite fertilizer.
2) by promoting crop root growth, strengthening the effect of improving activity of root system aspect, improving crop to the receptivity of nutrient, the specific absorption of nitrogen can be made to improve 10 15%, and the specific absorption of phosphorus improves more than 5%, and the specific absorption of potassium improves 10 20%; Can nutrient loss be reduced, avoid secondary pollution, reduce agriculture production cost.
3) product of the present invention is applicable to all kinds of crop and soil, has obvious disease-resistant drought resisting, effect cold-resistant, resistant to lodging after being manured into soil to crop, and effectively can improve the ability that soil stores nutrient.Use product of the present invention can improve crop yield more than 8 15%.
4) adding technology of nutrition potentiating and anti-caking block agent (98%DA-6 crude oil) in production of compound fertilizer is simple, and cost is low, produces and have a extensive future in Industry Promotion in synergia compound fertilizer.
