Abstract
The invention relates to a production method for a liquid water-soluble chelated secondary element fertilizer. According to the method, water is added to a reaction kettle firstly, then secondary elements are added to the reaction kettle in certain proportion, the mixture is heated, a chelating agent is added in certain proportion, the mixture has a chelation reaction, then one or more of a penetrant, a wetting agent, a spreading agent and the like are added in certain proportion and uniformly stirred and mixed, and the product is obtained. The product is fully water-soluble, quickly absorbed by crops and high in utilization rate, can prevent the nutrient deficiency symptom of the crops and meets the requirement of the NY2266-2012 standard.
Description
Technical field
The present invention relates to a kind of production method of chelating moderate-element liquid Water soluble fertilizer.
Background technology
Moderate-element by plant-growth required, requirement is medium, generally accounts for the nutritive element of 0.2%-1.0% of dry weight.As calcium, magnesium, sulphur etc.Calcareous fertilisers have longer history in application agriculturally, and along with the development of high-quality, high-efficiency agriculture, calcium deficiency phenomenon is on the rise, and calcareous fertilisers are also more and more subject to people's attention.Expert tells about south China in this year area and generally expands the effective crop species of fertiliser containing magnesium and soil, and magnesium deficiency phenomenon has the trend day by day increased the weight of, and the importance of fertiliser containing magnesium is more outstanding.In general, acid soil, swamp soil and the easy magnesium deficiency of sandy soil property.Sulphur is the element that crop demand is larger, and its requirement is suitable with phosphorus, and some crop even exceedes phosphorus to its demand.Farm crop a lack of sulfur can affect its normal growth, causes the decline of seed output and quality.
Liquid fertilizer (Fluid Fertilizer), also known as fluid fertilizer, be commonly called as liquid fertilizer, with the liquid product of the nutritive element needed for one or more crops, generally all with the large nutritive element of N, P, K tri-or wherein one of to be a kind ofly the theme, also usually comprise many micronutrient elements.
Moderate-element Water soluble fertilizer mostly is inorganic states in the market, and absorption rate is extremely low; Small part EDTA chelated microelement, obtained under pyroreaction by EDTA-2Na and metal oxide, to waste energy and cost is high, therefore expensive difficult in popularization, product of the present invention adopts sequestrant and metallic salt chelating, and temperature of reaction is low, and technique is simple, cost is low, is convenient to promote.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of production method of chelating moderate-element liquid Water soluble fertilizer, temperature of reaction is low, and technique is simple, and cost is low, and utilization rate of fertilizer is high.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
A production method for chelating moderate-element liquid Water soluble fertilizer, is characterized in that, carry out according to the following step:
1), first joined in reactor by water, then joined according to a certain percentage in reactor by one or both in four water-calcium nitrate, magnesium sulfate heptahydrate, heating is intermediates A;
2), add in reactor as one or more in the ethylenediamine tetraacetic acid (EDTA) of sequestrant, nitrilotriacetic acid, citric acid, hydroxyethylethylene diamine tri-acetic acid, bicine N-and polyacrylic acid, carry out chelatropic reaction;
3), add as one or more in the fatty alcohol-polyoxyethylene ether (AEO-3) of permeate agent, peregal, NP-10 and TWEEN Series and class of department series, stirring and evenly mixing product.
Described in step 1), the mass ratio of water, four water-calcium nitrate and magnesium sulfate heptahydrate is 1:0.5 ~ 1.5:0 ~ 1; Heating temperature is 35 ~ 60 DEG C.
Step 2) mass ratio of described amount of chelant and intermediates A is 0.1 ~ 1:1; The chelatropic reaction time is 20 ~ 40 minutes.
Described in step 3), the mass ratio of permeate agent consumption and intermediates A is 0.1 ~ 1:1.
The present invention has following Advantageous Effects:
1, patented product cost of the present invention is far below market like product, can reduce farmer's burdens.
2, metallic element is subject to the protection of ligand when chelating, is not vulnerable to the interference of other negatively charged ion, thus increases operation rate.
3, chelated microelement intramolecular charge is tending towards neutral, can prevent the impact being subject to plant materials electric charge, thus reach quick-acting effects.
