Description
Technical field
The present invention relates to fertilizer production technology field, be specifically related to a kind of high-activity humic acid trace element fertilizer and preparation method thereof.
Background technology
Farm crop, in process of growth, need trace element.Once so lack trace element, farm crop just can not healthyly grow normally, so need to add certain trace element in fertilizer.The trace element of using at present exists mainly with divalent-metal ion, enters after soil, and ubiquitous a large amount of carbonate of negative divalence and the phosphate radical of the negative trivalent reaction water-fast carbonate of generation and phosphoric acid salt easily and in soil, be difficult for being absorbed by plants.So, in fertilizer, generally trace element can be generated to inner complex, increase micro-stability, avoid generating water-fast carbonate and phosphoric acid salt, micro-fertilization effect is improved greatly.
Humic acid can be improved soil, promotes the formation of soil agreegate, improves the function of soil exchange capacity.Humic acid all has obvious synergism to nitrogenous fertilizer, phosphate fertilizer, potash fertilizer.Humic acid can with various trace elements generation chelatropic reaction, generate solubleness good, the microelement chelate in the humic acid easily being absorbed by farm crop, is conducive to crop root part or Foliage Absorption.Humic acid can also make seed germinate ahead of time, seedling rate is high, it is vigorous that the prosperity of farm crop root system, above-ground plant parts nourishing body are grown, and food crop output is many.Humic acid, also to farm crop drought resisting, cold-resistant, disease and insect resistance and immunizing power, also has the quality of agricultural-food to be all significantly improved.
Prior art is to adopt alkaline process to extract humic acids, with the rotten potassium/rotten sodium form of the suspension liquid of 12%, 15% equal-specification (portioned product is dry through spraying) or further make liquid fertilizer with inorganic nutrients and sell, for flower gardening and spray drip irrigation system etc.Or in high-quality leonardite, add or do not add in part, trace element, then granulation, sells with soil conditioner form.The biochemical humic acid that domestic technology method is also produced by chemistry or microorganism fermentation process by agricultural wastes such as crop material, wood chip, bagasses is in addition that starting material make fertilizer product with micro-compound blending.Utilize in addition humic acids with trace element chelated technology: be heated to, in the liquid reaction medium of 80-100 ℃, add brown coal and leonardite and organic chelated reactant, the reaction times is 30-60 minute, extracts humus, and through precipitation, liquid is required product; In the liquid of gained, add alkaline matter sodium hydroxide or potassium hydroxide, continue abstraction reaction, the reaction times is 240-300 minute; Carry out oxidizing reaction, add hydrogen peroxide, the reaction times is 120-180 minute; Add citric acid or its esters and by the micro-inorganic salts of formula rate, carry out chelatropic reaction, the reaction times is 120-180 minute; According to the potential of hydrogen of final chelatropic reaction, allocate, make final potential of hydrogen reach neutral, the adjusting time is 10-30 minute; After sufficient reacting completes, make according to a conventional method dry process, obtain organic chelated trace element fertilizer.
It is low that but humic acid trace element fertilizer ubiquity prepared by these prior aries the activation capacity of soil phosphorus decomposing, solution silicon; Humic acid activity is low, and resistance to hard water is not enough; So kind and the addition of the easy antagonism trace element of trace element are few, the problem that utilization ratio is low.
Summary of the invention
In order to produce, improve soil nutrient utilization ratio raising soil activation, improve the humic acid trace element fertilizer of micro-kind and content, raising humic acid activity, increase resistance to hard water, the invention provides a kind of high-activity humic acid trace element fertilizer, comprise by weight following ingredients: high-activity humic acid 6-15, NaFeEDTA 0.1-3, EDTA manganese 0.1-3, EDTA zinc 0.1-6, boric acid 0.1-10, magnesium sulfate 10-15, auxiliary agent 0.5-1, soil activating agent 1-5, full water soluble fertilizer filler 0-7.
Preferably, described auxiliary agent is one or more the mixing in sapn, tween, trimethyl-glycine, silicone oil, polysiloxane, polydimethylsiloxane, hydroxy silicon oil or sodium lauryl sulphate.
Preferably, described soil activating agent is one or more the mixing in oxalic acid, citric acid, tartrate, acetic acid, oxysuccinic acid, the Portugal's acid of acetic acid Huoα-one.
Preferably, described full water soluble fertilizer filler is one or more the mixing in ammonium sulfate, biological ferment powder, saltpetre or urea.
The present invention also provides a kind of preparation method of high-activity humic acid trace element fertilizer, by weight, in high-activity humic acid 6-15, add following ingredients to mix: NaFeEDTA 0.1-3, EDTA manganese 0.1-3, EDTA zinc 0.1-6, boric acid 0.1-10, magnesium sulfate 10-15, auxiliary agent 0.5-1, soil activating agent 1-5, full water soluble fertilizer filler 0-7, to mixing.
Preferably, described auxiliary agent is one or more the mixing in sapn, tween, trimethyl-glycine, silicone oil, polysiloxane, polydimethylsiloxane, hydroxy silicon oil or sodium lauryl sulphate.
Preferably, described soil activating agent is one or more the mixing in oxalic acid, citric acid, tartrate, acetic acid, oxysuccinic acid, the Portugal's acid of acetic acid Huoα-one.
Preferably, described full water soluble fertilizer filler is one or more the mixing in ammonium sulfate, biological ferment powder, saltpetre or urea.
Beneficial effect of the present invention comprises:
1. the present invention adds soil activating agent class material in humic acid trace element fertilizer, improves soil nutrient utilization ratio, especially improves available phosphorus and available silicon content in soil, makes the phosphorus decomposing of soil, the activation capacity of solution silicon increases greatly.Activator species is mainly that one or several the mixture by oxalic acid, citric acid, tartrate, acetic acid, oxysuccinic acid, acetic acid, the acid of α-Tong Portugal combines, its main mechanism is: 1. competition coordination site between organic acid and phosphate radical, reduces the absorption of soil to phosphate radical; 2. between the iron-aluminium oxide in organic acid and soil, hydrate, there is complex reaction, change the electric charge of these adsorbent surfaces, thereby reduce soil, the absorption of phosphate radical is fixed; 3. sour solvency action, due to plant secretion organic acid, pH in Rhizosphere obviously reduces, thereby has promoted the dissolving of insoluble P contained compound, improves the biological effectiveness of phosphorus; 4. eliminate Soil Phosphate Absorbing Capacities site; 5. the complex reaction between the metal ion such as organic acid/organic anion and Fe, Al and Ca, causes the dissolving of P contained compound, thus the phosphorus in activating soil; 6. because the acid of α-Tong Portugal, citric acid, oxalic acid dissolve silicates class material are the most effective, thereby can increase available silicon content in soil.
2. high-activity humic acid material of the present invention, through oxidation to a certain degree, significantly improves its phenol, hydroxy radical content, promoted significantly the ionising effects of humic acids, reach anti-hard water effect, and add tensio-active agent, more can improve the validity of humic acids under hard water environment.
3. micro-starting material of the present invention adopt full chelating state, not only can improve micro-kind, effective content, have also strengthened micro-utilization ratio.Because sequestering action is the title complex with ring texture being combined into by central ion and polydentate ligand.In the structure of inner complex, necessarily there are one or more polydentate ligands to provide multipair electronics and centrosome to form coordinate bond.So just can avoid during trace element is manured into soil, by the various weak acid in soil, with negatively charged ion, being fixed, form undissolvable inorganic salt, cannot provide nutrient to crop.
4. high-activity humic acid trace element fertilizer of the present invention not only improves micro-kind, effective content and utilization ratio; Complete water-soluble without slag, useful to environment; Product use range is large, can under hard water condition, use; Soil nutrient utilization ratio is also greatly enhanced.
