Abstract
The invention discloses a preparation method of zinc humate synergistic fertilizer. The preparation method comprises the following steps of mixing humic acid and water according to a mass ratio of 1: (4-6), adjusting a pH value to 5.65-5.85 by hydrochloric acid or sulfuric acid with a concentration of 8-12wt%, adding a zinc sulfate heptahydrate solution with a concentration of 10wt% into the mixture, wherein the mass of the zinc sulfate heptahydrate solution is 2.5-3 times that of the water, carrying out a reaction process at a temperature of 70-80 DEG C for 2-3h, carrying out drying at a temperature of 75-85 DEG C and carrying out grinding. The preparation method has simple and easy processes. A method for extraction of humic acid from brown coal by a base-dissolving acidification technology has a high extraction rate and simple processes. The preparation method has good chelating reaction effects and has a chelating rate more than 90%. The zinc humate synergistic fertilizer can be mixed with other common chemical fertilizer according to a certain ratio. An experiment proves that the zinc humate synergistic fertilizer has fertilizer efficiency better than that of the common chemical fertilizer and can improve soil.
Description
Technical field
The invention belongs to and belong to technical field of fertilizer, be specifically related to the synthetic method that a kind of zinc rotten acid increment is fertile.
Background technology
Scientific agricultural planting shows, be supplied to the various nutrient elements needed for healthy growth of crops, depend on multi-functional, the Composite of fertilizer, the acts and efforts for expediency only in this way effectively could controlling single chemical Term Fertilization increment and the land deterioration trend caused thus.According to domestic and foreign literature, humic acids is a kind of good soil improvement agent, and it is lower as fertilizer efficiency during fertilizer separately, but with chemical fertilizer with the use of time not only can improve chemical fertilizer utilization ratio, strengthen the fertilizer efficiency of chemical fertilizer, can also soil be improved, culture fertility.In addition humic acids or the amendment of medium trace element, sequestrant, have the effect of synergy to micro-fertilizer.Zinc element is also indispensable in crop growthing development process, plays an important role to the various biochemical reaction in plant materials and protein synthesis.Therefore, after humic acids and trace element zinc chelating, the output that greatly can improve farm crop in common fertilizer is added into.
Trace element conventional in current agriculture production is manured into soil mainly with inorganic salt form, very easily deteriorates to indissoluble salt, its utilization ratio is reduced and even all lost efficacy.And humic acids in its chemical structure with a large amount of active groups, and the carboxyl higher with stability and phenolic hydroxyl group are key structural feature, can and metal ion between there is sequestering action, become fulvo acid chelated microelement, thus improve plant to the peanut of trace element.The manufacturer of the rotten sour enhanced fertilizer of synthesis zinc is a lot, but some focus on the diversity of trace element, and focus on humic acids and micro-sequestering action, the absorption rate that result in trace element is low, reduces the effect of fertilizer efficiency.
Summary of the invention
The object of the present invention is to provide a kind of zinc humic acids to rise in value fertile, the preparation method of this increment fertilizer is provided simultaneously.
For achieving the above object, the present invention adopts following technical scheme:
The preparation method that a kind of zinc humic acids increment is fertile, comprise the following steps: by humic acids and water 1:(4-6 in mass ratio) mix after, by the hydrochloric acid of 8-12 wt % or sulfuric acid adjust ph to 5.65-5.85, then the Zinc vitriol solution of the quality 2.5-3 10 wt % doubly of water is added, 70-80 DEG C of reaction 2-3h, 75-85 DEG C of oven dry afterwards, grind after be zinc humic acids finished product.
In aforesaid method, described humic acids utilizes alkali-soluble acid analysis method to extract from brown coal.
Utilize alkali-soluble acid analysis method from brown coal, extract humic acids specifically to comprise the following steps: will the brown coal of 80-100 mesh sieve be crossed after 60-70 DEG C of dry 2-3h, the sulphuric acid soln adding 15 ~ 20wt% soaks 8-12h, filter residue is stayed in filtration, sodium hydroxide solution to the liquid-solid mass ratio adding 1-2 wt % in filter residue is (8-12): 1, then 60-90min is reacted at 60-70 DEG C, carry out centrifugal after being cooled to 20-30 DEG C, the centrifugal 5-10min of 3000-4000r/min, collect supernatant liquor, the sulphur acid for adjusting pH adding 15-20 wt % in supernatant liquor separates out precipitation to 2-3, then carry out suction filtration and obtain filter cake, after using 20-50ml distilled water wash again, 60-70 DEG C of oven dry, obtain humic acids, wherein total humic acid content is greater than 70%, moisture is less than 10%, belong to first grade, the add-on of the sulphuric acid soln of described 15-20wt% flooded brown coal.
Major advantage of the present invention has: method is easy and simple to handle, simple.Utilizing alkali-soluble acid analysis method from brown coal, extract humic acids is a kind of high and fairly simple method of extraction yield.The chelatropic reaction condition optimizing by experiment of the inventive method, the effect of chelatropic reaction is very good, and chelation percent can reach more than 90%.The zinc that utilizes aforesaid method to prepare rotten acid increment fertilizer can add by a certain percentage with other common chemical fertilizer and mixes, better than the fertilizer efficiency of common chemical fertilizer through experimental verification, and has the benefit of improvement soil.
