Abstract

The invention discloses a selenium-rich type slow-release watermelon planting fertilizer and a preparation method thereof. The selenium-rich type slow-release watermelon planting fertilizer is prepared from the following raw materials in parts by weight: bentonite, carbon dust, starch, epoxy resin, cement, gypsum powder, sodium selenite, selenium powder, vinegar dregs, ammonium chloride, aloe dregs, a 50% pirimicarb emulsion, peanut dregs, saw dust and a proper amount of water. The selenium-rich type slow-release watermelon planting fertilizer is a selenium-rich organic fertilizer which can be used as a basic fertilizer for planting watermelons, the content of selenium in the watermelons can be greatly increased, then the watermelons can be of a nutrient planting variety, and the utilization rate of the selenium element is greatly increased since the selenium element is combined and adsorbed together with modified bentonite; in addition, the insect resistance of the fertilizer can be improved; distiller's grains, aloe dregs and the like which have the insect expelling capability are adopted as basic organic matters, so that agricultural insects can be prevented from eating watermelon seedlings, and the survival rate of the watermelon seedlings can be increased.

Description

A kind of selenium-rich type slow release growth of watermelon fertilizer and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to a kind of selenium-rich type slow release growth of watermelon fertilizer and preparation method thereof.

Background technology

Bentonite is the clay mineral with montmorillonite as main component.Montmorillonite has the structure of simple Oblique Crystal, it is a kind of aqueous dioctahedron or trioctahedral layer aluminosilicate mineral, two-layer silicon-oxy tetrahedron is had in the outside of single cell, middle one layer of hydrogen-oxygen aluminum of folder is octahedra, and in tetrahedron and octahedron, the silicon ion of high price and aluminium ion can be by its cation replacements at a low price, make montmorillonite structure cell electronegative, become a big anion, so that it has the ability of Liquidity limit, but to Anion-adsorption less effective.

Flaky graphite has preferable electric conductivity, but its layer structure is allowed to be not suitable for being individually used in conducting resinl, to be generally used in mixed way with white carbon black.Spherical carbon black particle is filled between the graphite of stratiform, applies certain pressure to graphite linings so that it is can preferably contact.The great advantage of graphite conductive adhesive is that Performance comparision is stable, has certain acid and alkali-resistance ability, and cheap, relative density is little, and dispersive property is good, but resistivity is higher, is typically only used for middle resistance slurry.

Summary of the invention

In order to preferably play modified alta-mud absorption property in fertilizer, the present invention utilizes inorganic pore creating material to manufacture countless interconnective microporous pipeline in spray profit soil, thus has higher adsorption effect, and concrete grammar is as follows:

A kind of selenium-rich type slow release growth of watermelon fertilizer, it is characterized in that, be made up of the raw material of following weight portion: bentonite 20 ~ 30, carbon dust 6 ~ 8, starch 1 ~ 2, epoxy resin 0.5 ~ 0.8, cement 2 ~ 3, Gypsum Fibrosum powder 0.2 ~ 0.4, sodium selenite 1 ~ 3, selenium powder 0.5 ~ 1, vinegar groove 30 ~ 35, Chinese liquor groove 20 ~ 25, ammonium chloride 10 ~ 15, Aloe slag 10 ~ 14,50% Aphox Emulsion 0.5 ~ 1, peanut dregs 6 ~ 9, sawdust 12 ~ 17 and appropriate water；

The preparation method of a kind of selenium-rich type slow release growth of watermelon fertilizer, it is characterised in that include following step:

(1) being mixed by the water of epoxy resin and 4 ~ 5 times of its weight portions, stir to being completely dissolved after being heated to 70 ~ 80 DEG C, be subsequently poured into the starch and carbon dust of mixing, stirring and evenly mixing becomes viscosity to be homogenized；

(2) bentonite is removed sand, it is subsequently adding the viscosity homogenate described in (1), cement and Gypsum Fibrosum powder, stir to becoming uniform slurry while add waterside, then it is placed in the energising field that voltage is 300 ~ 360V, is slowly stirred 10 ~ 15min and makes carbon dust linear array, dry, then being put under the hot conditions of 500 ~ 550 DEG C calcining 30 ~ 40min and become the solid block of porous, crushing and screening is crossed 20 ~ 30 mesh sieves and is obtained granule；

(3) mixing sodium selenite, selenium powder, ammonium chloride and other following residual components being not directed to, be completely dissolved while add waterside stirring to solid；

(4) being added to (3) gained solution by the granule described in (2), unification is put in ultrasonic washing unit, power 700 ~ 800W, effect 20 ~ 25min makes to be full of in micropore solution, after completing, granule is dried, again put into repetition second adsorption in solution, after again drying, obtain modified particles；

(5) mixing vinegar groove, Chinese liquor groove, Aloe slag, peanut dregs and sawdust are first milled to uniform thickener, are subsequently adding (4) described residue lysate and modified particles, finally by slurry-spraying pelletizing.

Bentonite is prepared the method for adsorbent and is substantially: the high-quality sodium bentonite selecting nonmetallic ore is raw material, 4g200 mesh inflammable micropowder carbon dust and 2g starch is mixed at dry 100g bentonite after removing sand, add appropriate water and stir evenly the granule being squeezed into a diameter of 3mm, dry, high temperature sintering again, owing to losing of water of crystallization and inflammable micropowder combustion generate CO₂Releasing, define substantial amounts of micropore.

The final purpose of the present invention is for the mineral element of sorption chemical element, the most tiny by the micropore stayed after carbon dust high-temp combustion, the inorganic elements of fertilizer first must be dissolved, it is reinfiltrated in tiny hole, but there is Railway Project here: 1, the surface tension of water is very big, penetrate in trickle hole the most slowly and more difficulty；2, the inorganic chemistry element after dissolving is through dilution, even if permeating completely, amount is the least；3, the micropore manufacture being made up of carbon dust microgranule is micropore, is present in inside bentonite, and the most burned rear micropore formed belongs to air-tight state, it is impossible to reserve, let alone absorption.

nullSeveral measures of the present invention just solve problem above，First carbon dust is processed modification，Using a kind of viscosity, epoxy resin that is stronger and that have electric conductivity joins in carbon dust after diluting as binding agent for we，Stirred postadhesion is on carbon dust surface，Become the carbon dust microgranule of a kind of sticky particle，Then carbon dust is added in spray profit soil，Freely it is energized under the electric field action of conduction，Carbon dust freely connects in the case of conduction，Form toner chain，And the effect of epoxy resin be that make chain there is a period of time (epoxy resin becomes advanced technology already as the binding agent of electric conductivity，Effect is obvious)，Then according to step，High temperature sintering，So form micro-tube，Rather than micropore，Ul-trasonic irradiation is carried out the when of being then placed in the chemical element dissolved，The surface tension of the least water，Finally dry，Carry out second adsorption simultaneously，So chemicals quality of residual will be greatly improved，In order to improve the water absorbing properties of spray profit soil particle and rapid functions/drying，It is especially added with a certain amount of cement，Add strong absorptive and maintain spray to moisten the stability that soil particle is certain.

Beneficial effects of the present invention: this is the organic fertilizer of a kind of selenium-rich, the plantation of Citrullus vulgaris can be used for as base manure, the Se content of Citrullus vulgaris can be greatly improved, belong to the varieties of plant of a kind of auxotype, absorption is combined with modified bentonite, substantially increase the utilization rate of selenium element, in addition, this fertilizer can also improve insect resistace, the basic organic matter used has vinasse and Aloe slag etc., itself just has the ability driving away insect pest, prevents agricultural pests from eating up watermelon seedlings, improves the survival rate of watermelon seedlings.
