Abstract
The invention relates to a production method for a liquid water-soluble chelated trace element fertilizer. According to the method, water is added to a reaction kettle firstly, then trace elements are added to the reaction kettle in certain proportion, a chelating agent is added, the mixture is heated for a chelation reaction, then a penetrant, a wetting agent, a spreading agent and the like are added 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 NY1428-2010 standard.
Description
Technical field
The present invention relates to a kind of production method of chelated microelement liquid Water soluble fertilizer.
Background technology
Liquid fertilizer (Fluid Fertilizer), also known as fluid fertilizer, being commonly called as liquid fertilizer, is with the liquid product of the nutritive element needed for one or more crops, generally all based on the large nutritive element of N, P, K tri-or wherein one of a kind of, and comprise lot of trace nutritive element.
Trace element fertilizer, usually referred to as micro-fertilizer.Refer to the fertilizer containing micronutrient element, crops absorbs consumption few (for major element fertilizer).Although crop is little to micro-requirement, they are the same with major element, be of equal importance, can not replace mutually crop.Using of micro-fertilizer, on the basis of nitrogen, phosphorus, potash fertilizer its fertilizer efficiency of competence exertion.Meanwhile, under different nitrogen, phosphorus, potassium level, crop is not identical to the reaction of the first rope of trace yet.In general, easily there is the situation lacking trace element in low productive soil; High production soil, along with improving constantly of yield level, crop to trace element need also can correspondingly increase.Therefore, necessary compensating fertilizer, if but attempt reduces the amount of application of macroelement fertilizer, and only by enriching micro-fertilizer to obtain high yield, be also wrong.
Trace 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 its 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 chelated microelement 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 chelated microelement liquid Water soluble fertilizer, is characterized in that carrying out according to the following step:
1), first water is joined in reactor, one or more in Zinc Sulphate Heptahydrate, iron vitriol, cupric sulfate pentahydrate, manganese sulfate monohydrate, ammonium molybdate, Sodium orthomolybdate, boric acid, borax being joined according to a certain percentage in reactor, is intermediates A again;
2), add 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 in reactor, heating, carries out chelatropic reaction;
3), add as one or more in permeate agent, wetting agent and the spreading agents such as the fatty alcohol-polyoxyethylene ether (AEO-3) of permeate agent, peregal, NP-10, TWEEN Series and class of department series, stirring and evenly mixing.
Water described in step 1) and Zinc Sulphate Heptahydrate, iron vitriol, cupric sulfate pentahydrate, manganese sulfate monohydrate, ammonium molybdate, Sodium orthomolybdate, boric acid, borax mass ratio are 1:0.10 ~ 0.70:0 ~ 0.20:0 ~ 0.20:0 ~ 0.25:0 ~ 0.10:0 ~ 0.10:0 ~ 0.15:0 ~ 0.15.
Step 2) mass ratio of described amount of chelant and A is 0.1 ~ 1:1, the chelatropic reaction time is 20 ~ 40 minutes, and temperature of reaction is 35 ~ 60 DEG C.
Step 2) mass ratio of described permeate agent consumption and 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.
