Abstract
The invention relates to a humic acid liquid fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. The fertilizer comprises the following effective components in percentage by weight: 4-16% of humic acid, 5-14% of effective nitrogen, 4-9% of phosphorus pentoxide, 4-11% of potassium oxide, 0.02-0.35% of trace element zinc, 0.04-0.70% of manganese, 0-0.6% of copper, 0-0.7% of iron (ferrous iron), 0.02-0.2% of molybdenum, 0.02-0.35% of boron and 0.01-0.5% of chitosan. The preparation method comprises the following two process steps: the preparation of a humic acid activating clear liquid, and the addition and chelation of various nutrient elements. The liquid fertilizer is a non-precipitating and non-flocculent clear liquid, and is especially applicable to trickle irrigation and spraying devices.
Description
Affiliated technical field
The invention belongs to technical field of fertilizers, particularly a kind of humic acid liquid fertilizer and preparation method thereof.
Background technology
Along with agricultural sustainable development, the industrial scale of liquid fertilizer will constantly develop and enlarge.U.S.'s liquid fertilizer turnout accounts for 30% more than of total fertiliser prodn amount.In China, the production of nuisanceless liquid fertilizer and application are also being risen and are being enlarged day by day.Liquid fertilizer is compared with solid fertilizer, have fertilizer efficiency fast, balanced in nutrition, use advantages such as facility.
Chemical fertilizer (comprising liquid and solid fertilizer) plays remarkable effect to improving crop yield.But it has also brought harms such as the hardening of soil, salinification, pollutions; The long-time chemical fertilizer that uses makes serious reduction of soil fertility even forfeiture.Fertilizer has increases soil fertility, and improves advantages such as crop quality.The part but fertilizer also comes with some shortcomings, slow like fertilizer efficiency, yield poorly.If want the output height, then must roll up organic manure application rate, but the resource-constrained of fertilizer, the needs in a large amount of soils far in short supply.
Summary of the invention
Cause soil compaction to chemical fertilizer in the existing fertilizer; Life-time service can make serious reduction of soil fertility or forfeiture; Fertilizer; Problems such as fertilizer efficiency is slow, yield poorly, the present invention provides a kind of humic acid liquid fertilizer and preparation method, and this fertilizer can remedy the deficiency of chemical fertilizer, two types of fertilizer of fertilizer preferably.Promptly, make it to form huge legendary turtle compound (and compound of other chemical combination form), thereby make fertilizer have quick-acting, the double properties of slow property is arranged again with fertilizer such as nitrogen, phosphorus, potassium through effective activation to humic acids.Simultaneously, life-time service can make soil fertility be improved.What is more important make crop quality be improved significantly.
The effective ingredient of liquid fertilizer of the present invention and weight percent are:
Humic acids 4～16%, available nitrogen 5～14%, Vanadium Pentoxide in FLAKES 4～9%; Potassium oxide 4～11%, trace element zinc 0.02～0.35%, manganese 0.04～0.70%; Copper 0～0.6%, iron (ferrous iron) 0～0.7%, molybdenum 0.02～0.2%; Boron 0.02～0.35%, and chitin (chitosan) 0.01～0.59%.
Humic acids derives from natural product, and like weathered coal, peat, brown coal etc., its reserves are very abundant in China.
Nitrogen phosphorus potassium and various trace element all adopt the chemical industry product.
The preparation method of humic acid liquid fertilizer of the present invention comprises the preparation of humic acids activation clear liquid and in clear liquid, adds various nutritive element huge legendary turtles and close two steps:
(1) by weight per-cent is with weathered coal (granularity contains humic acids more than 50% more than 60 orders), NaOH (or KOH, Na
2CO
3, K
2CO
3), K
2SO
3(or NaSO
3, (NH
4)
2SO
3) urea, water, the ratio in 1: 0.1～0.3: 0.01～0.1: 0～1.0: 5～20.0 is formed, and under 80 ℃～100 ℃ conditions, in stirred autoclave, reacts 1.5～5 hours.Through deposition, centrifugal, change its clear liquid over to huge legendary turtle then and close in the stirring tank, treat and each composition effect described below.
(2) be added to huge legendary turtle to each nutrition according to following ratio by weight percentage and close in the stirring tank, the humic acids clear liquid is 100, and each nutritive ingredient is:
Temperature is normal temperature～55 ℃, fully stirs, fully after the dissolving, with sulfuric acid (or phosphoric acid) or NaOH (or KOH) conciliation PH6～7.5.
Chitin (chitosan) is a kind of auxiliary agent, and its deacetylation forms water-soluble thing greater than 80% after acidification, and it has the harmful mushroom breeding of inhibition, and the effect of strong seedling growth encourage is arranged.K
2SO
3, Na
2CO
3, (NH
4)

3Be a kind of acvator, it and humic acids interaction energy increase the huge legendary turtle of humic acids and close constant and solubleness.
Major advantage of the present invention is:
Make full use of the natural weathered coal that has than high humic acid content (weight ratio is greater than 50%), activated, directly be used as liquid fertilizer after extracting.Activation humic acids and the necessary nutrition of plant growth: nitrogen, phosphorus, potassium, zinc, manganese, iron, copper plasma form the huge legendary turtle compound, and the fertilizer efficiency that makes it its product had not only had quick-acting but also the two-ways regulation property of certain slow property is arranged.The liquid fertilizer that present technique is produced is a kind of clear liquid that does not precipitate, do not flocculate; Be particularly suitable for drip irrigation, sprayer apparatus use; The present invention relates to a kind of natural positively charged ionic superpolymer chitin (chitosan); It and humic acids act synergistically, and increase drought-resistant moisture-preserving ability of crop and the anti-adversity ability of crop, play the effect in antibacterial strong sprout.
Fertilizer of the present invention can copy aforementioned the inventive method to make suitable different soils by different ratios by each composition in ratio range, Different Crop, the fertilizer of the various nutrient contents that different growing stage is required.
Embodiment
Get weathered coal (grinding particle size is more than 60 orders, and humic acids content is greater than 50%) 10kg, KOH1.2kg; Urea 7.0kg, potassium sulfite 0.4kg, water 60kg drop in the stirring tank; Temperature is controlled at 100 ℃ ± 50 ℃; Reacted 3 hours, spinning then (or through the natural sedimentation more than 20 hours) forwards supernatant liquid to huge legendary turtle and closes in the stirring tank.Drop into diammonium phosphate 10kg then, Repone K 15kg, zinc sulfate 0.4kg, manganous sulfate 0.5kg, boric acid 0.6kg, ammonium molybdate 0.05kg, (20 ℃) fully stir dissolving fully at normal temperatures.
Test PH6.76 because of potential of hydrogen is suitable, needn't transfer its pH value again.
Use through brooder vegetables (eggplant, cucumber, grape etc.), the result shows: compare with waiting nutritive fertilizer check plot.Cucumber production promoting 15～25%; Eggplant raising the output 16～28%: grape yield increasing 10～24%, the most important thing is to use the product taste that this fertilizer produces and become pure, show that its quality has obtained remarkable improvement; Nitrate content reduces greatly, has reached the pollution-free food A level level of national regulation.
