Abstract

The invention discloses a filling nutrient liquid fertilizer and a preparation method therefor. The filling nutrient liquid fertilizer is prepared from the following raw materials in parts by weight: mixed amino acid mother liquor, trace elements, monopotassium phosphate, zinc sulfate powder, citric acid, sodium humate, EDTA (ethylene diamine tetraacetic acid) manganese chelate, a growth regulator, a fertilizer additive and a proper amount of water. High-efficiency production increasing factors contained in the fertilizer solve the problem that a root system and stem leaves decline early due to the fact that much water of rice and wheat is lost in a filling period because of transpiration; and the fertilizer can be sprayed to enhance photosynthesis, accelerate filling, and reduce vacant shells, so that the filling is sufficient and grains are full. And stable yield and high yield are achieved.

Description

A kind of grouting nutritional liquid fertilizer and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to a kind of grouting nutritional liquid fertilizer and preparation method thereof.

Background technology

The nutritious fertilizer seen in the market is all solid foliage fertilizer and liquid foliage fertilizer mostly, solid foliage fertilizer is more simpler on producing, after first various raw material being pulverized in pulverizer, exact value is weighed according to the requirement of formula, put into tempering tank, stir, stir rear directly weighing, packing, namely obtain finished product.

It is complicated that liquid foliage fertilizer produces comparatively solid, its production technique is different according to the states of matter difference of material, liquid level foliage fertilizer based on solid material, according to recipe requirements, solid material is weighed respectively, after pulverizing, join in mixing grass in a certain order, realize in tempering tank being added with a certain amount of aqueous solution, or dissolve in dissolving tank, send into hold tank, passing into tempering tank from hold tank.Liquid foliage fertilizer is produced with liquid raw material, the requirement of peace formula, only need by liquid starting material several respectively, drop into or be pumped in tempering tank from storage tank, have solid-state and liquid foliage fertilizer that is liquid raw material, first the metering of liquid raw material according to formula is dropped into or pump in tempering tank, then by the solid feed after pulverizing with after formula metering, join in tempering tank in sequence and mix, above multiple nutrients fertilizer is all a kind of simple several raw material mixing.

Calcium explained hereafter fertilizer, ubiquity utilization ratio is low.Crop difference problem.

Summary of the invention

In order to improve the utilization ratio of fertilizer, reduce the loss of fertilizer, protection of the environment; the present invention adds the fertilizer additive of viscosity in common liq fertilizer; effectively can slow down the evaporation of foliar nutrient, allow fertilizer in the superficial residence of crop longer time, realize particular by following methods:

A kind of grouting nutritional liquid fertilizer, it is characterized in that, be made up of the raw material of following weight part: mixed amino acid mother liquor 800 ~ 1000, trace element 10 ~ 14, potassium primary phosphate 35 ~ 50, zinc sulphate powder 60 ~ 70, citric acid 20 ~ 25, Sodium salts humic acids 10 ~ 15, EDTA Chelated Manganese 5 ~ 10, growth regulator 2 ~ 3, fertilizer additive 6 ~ 8 and appropriate water;

Described fertilizer additive is made up of following raw material: terra alba 10 ~ 15, Viscotrol C 4 ~ 6, polyvinyl alcohol 10 ~ 12, sodium stearate 1 ~ 2, N hydroxymethyl acrylamide 2 ~ 3, ethanol 8 ~ 10 are appropriate water; Preparation method is: by ethanol and water with 1: 10 ratio dissolve each other after put into reactor, add polyvinyl alcohol and N hydroxymethyl acrylamide, be heated to 70 ~ 80 DEG C, stirring and dissolving, mixing Viscotrol C and sodium stearate join in the water of 4 ~ 5 times of its total weight parts, bubble after stirring 10min, then join in aforesaid reactor, heating and thermal insulation, and stirring 0.5 ~ 2h carries out composite under the rotating speed of 300 ~ 500r/min, finally terra alba was finely ground to 200 mesh sieves to add in total material to stir and make emulsion, and was incubated for subsequent use and get final product.

To be in the milk the preparation method of nutritional liquid fertilizer, to it is characterized in that, comprise following step:

(1) mixed phosphate potassium dihydrogen, zinc sulphate powder, citric acid, Sodium salts humic acids and EDTA Chelated Manganese are in reactor, add the water of 4 ~ 6 times of its weight parts, be heated to 70 ~ 80 DEG C, be stirred to and dissolve completely, then mixed amino acid mother liquor is added, under heating and thermal insulation condition, 300 ~ 500r/min stirs 4 ~ 6h and carries out composite;

(2) by trace element and growth regulator mixing, add the water dilution of 15 ~ 20 times of its weight parts, then add fertilizer additive, under heating and thermal insulation 70 ~ 80 DEG C of conditions, slowly stir 30 ~ 50min and carry out degree of depth adsorption;

(3) mix the described product in (1) (2), under being incubated 70 ~ 80 DEG C of conditions, 600 ~ 700r/min stirring, 20 ~ 30min carries out chelating, cools after completing under normal temperature.

Described fertilizer additive is a kind of with polyvinyl alcohol resin monomer, binding agent N hydroxymethyl acrylamide is coordinated to be a kind of high performance water-soluble material prepared by main body, wherein add the sliminess that plant oil Viscotrol C increases main body, add sodium stearate as surfactant, then Viscotrol C and the perfection of resene monomer agree with, form a kind of additive with high bonding characteristic, present gluing form, finally add terra alba, refining grinding, determine the granularity of terra alba, add as a kind of structural agent, make main body more stable.

When fertilizer sprays the fine hair being easy to be subject to crop leaf surface on the page of crop and the surface directly touching blade, be difficult to the effect performing to fertilizer, a kind of surfactant of sodium stearate is added in fertilizer additive of the present invention, effectively can be furthered liquid fertilizer and crop leaf, mention contact area, thus improving the utilization ratio of fertilizer, this surfactant can also slow down the oily matter of crop surface growth spilling to the repulsive interaction of water soluble fertilizer simultaneously.

Beneficial effect of the present invention: the present invention produces the foliar nutrient inventing a kind of grouting according to the conventional requirement of plant growth, not only there is high-absorbility, the demand of growing nutrient element of filling stage crop is provided, simultaneously because the effect of fertilizer additive makes this foliar nutrient also have certain slowly-releasing adsorption, the fertilizer that furthers contacts with interlobate, even if dry, the residual components of fertilizer also can be close to the surface of blade, again fertilizer is dissolved when spraying water next time, again supply the sorption of blade, greatly reduce the waste situation of fertilizer, meanwhile also effectively reduce artificial usage quantity.
