Abstract
The invention relates to the technical field of water soluble fertilizer, especially the preparing method of secondary element water soluble fertilizer. The method is enriched by using storage with inexpensive dolomite as a raw material and processed with nitric acid solution, followed by modifying treatment and neutralizing treatment of conditioning agent, which leads to reduce the production cost of water soluble fertilizer and enhance the market competitiveness; But the method makes better compounding ratio of calcium, magnesium and other secondary elements in water soluble fertilizer. The method can effectively promote the absorption of plants, while allowing the water soluble fertilizer to form the one with the integration of nitrate nitrogen, ammonium nitrogen and amide nitrogen nitrogen nitrogen, which prompts the water soluble fertilizer to meet the nutrient requirements of different periods of the crop to ensure nutrient uniformity and sustainable supply to achieve sustained release effect.
Description
Technical field
The present invention relates to water soluble fertilizer technical field, especially a kind of moderate-element water-soluble fertilizer preparation method.
Background technology
Nutrient necessary to plant growing includes 17 kinds, and according to nutrient required in growing process
Number, be divided into a great number of elements, moderate-element, trace element, wherein a great number of elements is C, H, O, N, P, K, and moderate-element is
Ca, Mg, S, trace element is Fe, B, Mn, Cu, Zn, Mo, Cl, Ni.
Moderate-element plays vital effect in plant, is embodied in:
Calcium can improve the stability of membrane structure by the hydroxyl etc. of bridge joint phosphate with phospholipid and protein, and then can make thin
Born of the same parents maintain metastable interior environment, are cell and the surrounding bases that carry out material, energy and communication for information；There is maintenance
The function of plant cell wall construction, the putrefactive phenomenon that this function occurs during can effectively preventing mature fruit postharvest storage, from
And improve the storage quality of fruit；Calcium also can neutralize some acid that vegetable metabolic process produces, thus prevents too much organic acid
Cytotoxic.Magnesium is primarily present in plants in element and chlorophyll, is to plant plain and chlorophyllous components；Magnesium is in the new old generation of plant
Being most active component during thanking and be the fundamental of multiple enzyme, it is indispensable that magnesium is that plant is formed when protein and starch
Few；In addition sugar and the metabolism of energy in magnesium can also promote plant.
As fully visible, moderate-element, in plant, has important effect to plant growing, although plant centering amount unit
The demand of element is little, but as long as lacking moderate-element, will affect the normal growth of plant, causing yield and quality serious
Decline.
At present, China is more for the technical literature of secondary nutrients, but main for moderate-element water soluble fertilizer
Concentrating on and carry out being mixed with forming according to certain ratio by calcium nitrate, magnesium nitrate, water etc., this makes moderate-element Water soluble fertilizer
Nutrition the most single, inferior quality, and cost of material is higher.
Summary of the invention
In order to solve above-mentioned technical problem present in prior art, the present invention provides a kind of moderate-element water-soluble fertilizer system
Preparation Method.
It is achieved particular by techniques below scheme:
A kind of moderate-element water-soluble fertilizer preparation method, comprises the following steps:
(1) acid is molten: dolomite dust is broken to 10-100 mesh, adds nitric acid, is placed in reaction kettle for reaction 0.5-3h, consolidate
Slurry；Solid-liquid slurry is carried out solid-liquid separation, it is thus achieved that residue a and filtrate a；
(2) regulation: being mixed homogeneously with regulator in regulating reservoir by filtrate a, regulator addition reaches for making pH value
2.9-3.1, and standing processes 0.5-5h, solid-liquid separation, it is thus achieved that residue b and filtrate b in regulating reservoir；
(3) neutralize: filtrate b is mixed with nertralizer, in neutralizing still, react 0.5-2h, it is thus achieved that moderate-element Water soluble fertilizer
Material.
Described acid is molten, and wherein dolomite is the nitre that 1 ton of dolomite adds 0.6-3 cubic meter with the mass volume ratio of nitric acid
Acid.
Described nitric acid, its mass percentage concentration is 20-75%.
Described regulator, for one or more in calcium oxide, magnesium oxide, calcium carbonate, magnesium carbonate according to any matter
Amount is than the mixture of mixing.
Described neutralization, wherein filtrate b and nertralizer are that 1 ton of filtrate b adds 0.1-2 cubic meter according to mass volume ratio
Nertralizer.
Described nertralizer is ammonia, potassium hydroxide solution, any quality of one or any two kinds of urea liquid
Than mixing.
Compared with prior art, the technique effect of the present invention is embodied in:
By utilizing storage capacity to enrich, and cheap dolomite is as raw material, and is used the nitric acid molten process of acid, then
Process in conjunction with regulator regulation, neutralisation treatment so that the cost of manufacture of water soluble fertilizer reduces, and enhances the market competitiveness；
And make the calcium in the water soluble fertilizer made, the moderate-elements such as magnesium proportioning more excellent, it is possible to effectively facilitate the absorption of plant,
Enable to the water soluble fertilizer that water soluble fertilizer forms nitrate nitrogen, ammonium nitrogen, three kinds of nitrogen sources of amidonitrogen have concurrently simultaneously so that
The water soluble fertilizer obtained disclosure satisfy that the nutrient demand of crop different cycles, it is ensured that nutrient is uniform, and can persistently supply,
Reach the effect of slow release.
