Abstract

The present invention provides a production method for high-efficiency organic multicomponent microelement fertilizer. In the method, valonea extract, humic acid and organic matter containing nitrogen are used as organic complexing agents, and various trace elements such as boron, zinc, iron, molybdenum, etc., which are desired by crop, achieve complexation (chelation) reaction under certain conditions to prepare the high-efficiency organic multicomponent microelement fertilizer. The high-efficiency organic multicomponent microelement fertilizer which is in a liquid state and has high content of active ingredients can be dissolved by water, and the nourishment of the high-efficiency organic multicomponent microelement fertilizer is balanced and lasting. The high-efficiency organic multicomponent microelement fertilizer has obvious functions of balancing nutrients in crop bodies, raising resistance ability, increasing yield and improving product quality.

Description

A kind of production method of organic multicomponent microelement fertilizer

Technical field

The present invention relates to a kind of production method of chemical fertilizer, be meant a kind of production method of organic multicomponent microelement fertilizer especially.

Background technology

Use little fertilizer and be farm crop and realize high yield, high-quality, one of key measure efficiently.Little fertilizer generally can be divided into inorganic little fertilizer and organic little fertilizer.But inorganic little fertilizer is difficult for by crop absorption, and major part remains in and becomes the insoluble material in the soil or easily run off with rainwater, or produces antagonistic action and lost efficacy with other mineral in the soil, uses improperly also can produce some adverse consequencess.Organic little fertilizer can solve the variety of issue that inorganic little fertilizer runs in using, and developing organic little fertilizer is one of important directions of fertilizer industry development.Organic little fertilizer normally uses organic complex (chelating) agent and the inorganic salt of trace element to make through the complexing reaction.Organic complexing agent commonly used has EDTA (ethylenediamine tetraacetic acid (EDTA)), citric acid, amino acid, EDDHA (quadrol dihydroxy-benzene acetic acid), DTPA (diethylenetriaminepeacidcetic acidcetic), HEDTA (hydroxyethylethylene diamine three acetic acid).Existing organic little fertilizer often adopts a kind of organic complexing agent that metallic elements such as non-metallic element boron and zinc, iron, molybdenum are carried out the organic complex reaction, be difficult to reach ideal complexing effect, and also there is the deficiency of aspects such as cost height or complexing capacity be low in organic complexing agent, directly has influence on quality product, production cost and the application effect of organic little fertilizer.

Summary of the invention

The object of the present invention is to provide a kind of production method of organic multicomponent microelement fertilizer.It mainly adopts multiple organic complexing agent and substep complexing technology that the required various trace elements of crop is carried out complex reaction and makes, can overcome the deficiency that prior art exists, have that complexing capacity is big, production cost is low, balanced in nutrition lastingly, easily by plant absorbing, utilising efficiency height, amount of increase in production height, quality improving obvious effects.

The objective of the invention is to realize by the following technical solutions, the production technique of organic multicomponent microelement fertilizer is carried out according to following steps:

1. be that 2%～17% water is put into reactor with weight percentages of components, the adding weight percentages of components is 2%～13% itrogenous organic substance, itrogenous organic substance is taken from urea, triethylamine, thanomin, the methane amide at least a, after stirring thing to be added and water and dissolving each other, be that 0.5%～5.5% boric acid or borax add wherein again with component boron effective content weight percent, and under 20～85 ℃, stir 0.5～6 hour liquid organic boron of acquisition, be sample 1;

2. be that 3.5%～10% industrial valonex is put into another reactor with weight percentages of components, it with weight percentages of components 5%～30% water dissolution, regulate about pH7.5 with sodium hydroxide again, the adding weight percentages of components is 0.1%～3% hydrogen peroxide, reacts down at 20～85 ℃ to make sample 2 in 0.5～6 hour;

3. in sample 2, add weight percentages of components and be 2.5%～8.5% industrial humic acids and make sample 3;

4. be that 2%～6.5% zinc sulfate, component of iron effective content weight percent are that 0.5%～4.5% ferrous sulfate, component molybdenum effective content weight percent are that 0.5%～2% ammonium molybdate, component copper effective content weight percent are that 0.5%～2.5% copper sulfate, component manganese effective content weight percent are that 0.5%～3.5% manganous sulfate and excess water add in the sample 2 with component zinc effective content weight percent, under 60～110 ℃, carry out complexing (chelating) reaction in 0.5～4 hour and make sample 4;

5. with sample 4 and sample 1 mixing and stirring with 100～110 mesh sieve filtering solutions, the adding weight percentages of components is that 1%～5% Sodium dodecylbenzene sulfonate stirs and can obtain the finished product in the solution at last.

Mixing the organic multicomponent microelement fertilizer of being prepared by a certain percentage mutually, is formulated to the nutrient demand ratio in Different Crop and different soils fertility type, includes the multiple formulations model.

The present invention is further illustrated below in conjunction with embodiment.

Embodiment 1:

With weight percentages of components is that 2.2% water is put into reactor, adding weight percentages of components is 0.3% triethylamine, 1.5% thanomin, 0.2% methane amide, stir, be that 1% boric acid adds wherein again with component boron effective content weight percent, and stir down at 80 ℃ that to obtain liquid organic boron in 0.5 hour standby.With weight percentages of components is that 5% valonex is put into another reactor, it with weight percentages of components 10% water dissolution, regulate about pH7.5 with sodium hydroxide again, the adding weight percentages of components is 1% hydrogen peroxide, reacted 1.5 hours down at 80 ℃, add weight percentages of components then and be 3% humic acids, again with component zinc, iron, molybdenum, copper, manganese effective content weight percent is respectively 3.5% zinc sulfate, 0.5% ferrous sulfate, 2% ammonium molybdate, 0.5% copper sulfate, 0.5% manganous sulfate and excess water add wherein, the sample that carries out 1 hour complex reaction gained under 80 ℃ and the liquid organic boron mixing and stirring that makes at first be with 100 mesh sieve filtering solutions, and the adding weight percentages of components is that 3% Sodium dodecylbenzene sulfonate stirs and can obtain the finished product in the solution at last.
