Abstract
The present invention discloses one series of all-component chelated high efficiency trace element fertilizers containing trace elements essential for crops and its production process. The trace element fertilizers are produced through recipe design, chelation reaction of chelating agent and trace elements, addition of magnesia for pH value regulation and addition of dispersant. The trace element fertilizers are high quality chemical fertilizers with raised nutrient contents, lowered conductivity, capacity of promoting the absorption of crop, obvious yield increasing effect and other advantages.
Description
Technical field
The novel agricultural fertilizer manufacturing that the present invention relates to use on the agroforestry specifically relates to a kind of preparation method who contains the compound manure of multiple chelated microelements.
Background technology
Chelated trace fertilizer is meant that what formed by chelatropic reaction by organic sequestering agent and metal trace element ion is a kind of agrochemicals fertilizer of main component with multiple chelated microelements.Trace element has very strong specificity in the intravital effect of plant and animal, is can not lack with irreplaceable, and when undersupply, plant often shows specific shortage symptom, and crop yield reduces, and downgrade may have no harvest when serious.So the compound as fertilizer sources (little fertilizer) of the trace element that lacks carries out supply, helps the raising of output, scientific experimentation and production test confirm.
Along with modern agricultural development, people recognize that progressively trace element has very important effect to plant, and little fertile production technique has correspondingly also experienced the development of many decades.At present, there are some problems in Wei Liangyuansu production.No matter which kind of sequestrant preparation existing chelated trace fertilizer is, most of sodium hydroxide that adopts carries out pH regulator, and this will cause having in little fertilizer sodium ion to exist, and sodium ion can not be absorbed by crop as nutrient, and long-term application can cause the soil salinization.Meanwhile, owing to contain insoluble composition in this class chelated trace fertilizer, and, in the fertilising process, can form reunion owing to easily form antagonistic action between the trace element, can not disperse preferably, thereby can not effectively be absorbed by crop.
Summary of the invention
The purpose of this invention is to provide a class and contain multiple chelated microelements, and can better disperse, easily the complete-element chelating highly effective trace fertilizer that is utilized by plant absorbing.
Technical scheme foundation of the present invention:
1, easily lack the characteristics of trace element according to growth and development of plants, provide crop required micro-Cu, Fe, Mn, Mo, Zn, Co, B etc. satisfy demand of plant growth, avoid various hunger sign in plant to take place.
2, carry out as sequestrant in the process of chelatropic reaction at EDTA, adopt magnesium oxide to carry out pH regulator, both avoided causing the risk of soil salinization, can be crop again magnesium elements is provided, improve fertilizer total nutrient content because of the existence of sodium ion.Meanwhile, the magnesium elements that obtains by neutralization reaction is a chelating attitude magnesium, is more conducive to the absorption of plant.
3, in above-mentioned fertilizer, add chemical assistant, can promote various nutrients to disperse, guarantee the nutrient rapid absorption, strengthen the leaf dressing effect, improve fertilizer utilization efficiency with utmost point low surface tension.
The little fertilizer of complete-element chelating of the present invention is applicable to the chemical fertilizer of farm crop and plant, comprises following component:
(1) contains chelated microelements such as copper, iron, manganese, zinc, cobalt, magnesium;
(2) contain the inorganic salt of magnesium, molybdenum and boron;
(3) contain silicone based surface dispersant.
Further, above-mentioned complete-element chelating highly effective trace fertilizer is to select for use following component to process by following constituent content scope:
(1) the content summation of the Cu of chelating attitude, Fe, Mn, Zn, Co, Mg is 8-20 weight %;
(2) the content summation of the Mg of inorganic salt attitude, Mo, B element is 0.1-8 weight %;
(3) silicone based surface dispersant, content are 0.1-1.5 weight %.
Manufacture method of the present invention
1, raw material:
In the above-mentioned complete-element chelating highly effective trace fertilizer, sequestrant derives from the EDTA tetracid, zinc derives from zinc oxide, copper derives from ventilation breather, iron derives from commercially available chelated iron, be preferably EDTA (or DPTA) chelated iron that Shanghai Wintong Chemicals Co., Ltd. produces, manganese derives from manganous carbonate, described cobalt derives from cobaltous carbonate, and magnesium derives from light magnesium oxide, and boron derives from four water Sodium Tetraboratees, molybdenum derives from Sodium Molybdate Dihydrate, dispersion agent derives from silicone based surface dispersant, is preferably the silicone based tensio-active agent that contains the trisiloxane ethoxylate structure, comprises the not Keep away from rain that Shanghai Wintong Chemicals Co., Ltd. produces
TMThe fertile synergistic agent of superfine product medicine.
2, manufacturing process:
An amount of EDTA tetracid is dissolved in a certain amount of aqueous solution, and heating makes it to dissolve fully; The CuCO that adds certain proportioning
3Cu (OH)
2, MnCO
3, ZnO, CoCO
3, be heated to 80-100 ℃, and under this temperature, stirred 1-3 hour; After treating that above-mentioned solution is transparent, to wherein adding proper addition of MgO, regulate the pH value, add a certain amount of Sodium Tetraborate, Sodium orthomolybdate, EDTA (or DTPA) chelated iron and dispersion agent (Keep away from rain not then successively to 4-7
TM), fully stir, to clarification, filtered while hot, filtrate is carried out spraying drying.
The advantage of complete-element chelating highly effective trace fertilizer of the present invention is:
1, extremely low sodium salt composition in the fertilizer can reduce fertilizer EC value, prevents the soil salinization.
2, containing in the fertilizer must be chelating attitude magnesium, and this inner complex can be satisfied the demand of crop to magnesium by the crop rapid absorption.
3, product property is stable, and no crystallization does not have precipitation, can guarantee that crop effectively absorbs.
4, with strong points, specificity is good, and prescription satisfies equilibrium relationship between soil, crop, the fertilizer, satisfies crop each breeding time, vegetative period, ripening stage demand to various trace elements.
5, comprise the required various trace elements of crop, the nutrient height, increase yield significantly uses this product can make field crop volume increase 10-15%, fruit volume increase 15-25%, vegetables volume increase 15-30%, flower characteristic obviously promotes.
