Description

High-effective microorganism fertilizer that a kind of maize planting is used and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, it is fertile and preparation method thereof to be specifically related to high-effective microorganism that a kind of maize planting uses.

Background technology

Because zeolite has vesicular structure, there is very large avidity to water, thus can absorb moisture and gaseous constituent, strengthen the water content in soil, improve drought-resistance ability, increase the diffusion of gas, facilitate the respiration of soil.Some crosses sand or excessively sticky soil, is unfavorable for preserve moisture and fertility and farming; After applying zeolite improvement, sandy soil can be made to be unlikely to leak Lou fertile, and clayey soil also can change its three-phase proportionlity, thus show good Drafting Ability, therefore, during zeolite is manured into soil, obvious effect is played to the perviousness improving soil, mainly have adjusted rate of permeation, do not make its excessive infiltration and cause the Lou fertilizer that leaks, also do not make it permeate bad, and caused the reductive action of containing, both is all disadvantageous to plant growth.

Nowadays agricultural, plant husbandry have become the important indicator of a national productivity, in order to improve productivity effect, large-scale agricultural, plant husbandry are accelerated to produce, and often cause planting site nutrition to put down weary, and inevitably abuse chemical fertilizer improves production, a large amount of uses of fertilizer, really output can be improved, but fertilizer within the time of plantation, all can not utilize effectively, there is data declaration: the fertilizer component of more than 30% enters soil, river because of rain drop erosion, causes serious pollution.Cause algae " wildness ", fish are because of anoxic mortality, and cause ecological serious unbalance, spend in river regulation every year, the expense of land forming should not be underestimated.

Summary of the invention

In order to improve soil, realize the slow-release function to mineral nutrient element, improve utilization rate of fertilizer, reduce because of the pollution of fertilizer abuse to environment, the present invention realizes by the following method:

The high-effective microorganism that a kind of maize planting is used is fertile, it is characterized in that, be made up of the raw material of following weight part: rare HCl10 ~ 15 of natural zeolite 50 ~ 55,2mol/L, 6wt%NaCl solution 150 ~ 180, soil beneficial microorganism microbial inoculum 8 ~ 10, rice hull ash 15 ~ 20, kaolin 15 ~ 25, bone meal 5 ~ 10, potassium oxide 15 ~ 20, wheat-flour 30 ~ 35, cyclodextrin 3 ~ 5, fused(calcium magnesium)phosphate 10 ~ 14, straw powder 15 ~ 20, sheep excrement ball 10 ~ 16 and appropriate water;

A preparation method for the high-effective microorganism fertilizer that maize planting is used, is characterized in that, comprise following step:

(1) natural zeolite is first carried out preliminary pulverizing, become the bulk of 6 ~ 8cm diameter, then the high temperature kiln calcining 6 ~ 8h of 800 ~ 1000 DEG C is put in unification, and it is broken to carry out secondary fine fine powder after cooling, became the particle of 40 ~ 60 mesh sieves, finally rare HCl of particle pulvis 2mol/L was eluriated 2 ~ 3 times;

(2) granule of (1) gained is put into the NaCl solution of 6wt%, under the constant temperature of 30 DEG C, 140r/min stirs 18 ~ 20h, with deionized water drip washing 2 ~ 3 times after completing, and last dry for standby;

(3) mixed with the water of 10 times of its weight parts by soil beneficial microorganism microbial inoculum, dilute, add the zeolite granular of (2) described modification, unification puts into supersonic cleaning machine, power 700 ~ 750W, temperature 30 DEG C, and effect 2 ~ 2.5h adsorbs;

(4) mix wheat-flour, cyclodextrin, straw powder, add water and be modulated into thickener, then add the total material described in (3), after stirring, dry and be again ground into granule;

(5) mix kaolin and other remaining component, add (4) gained granule, add water for ball milling 15 ~ 20 one-tenth homogenate in right amount, last spray granulating.

Fertilizer utilization NaCl solution of the present invention is improved natural zeolite, obtain a kind of modified zeolite particle ammonium nitrogen to adsorption sustained-release function, experimentally measure the best modified effect of different N aCl strength of solution simultaneously, accurately take the zeolite of certain mass in the tool plug Erlenmeyer flask of 250ml, adding 100ml massfraction is respectively 0, 2%, 4%, 6%, 8%, 10%, the NaCl solution of 15%, respectively at 30 DEG C, 40 DEG C, 50 DEG C, at 60 DEG C of temperature, to vibrate in water bath with thermostatic control shaking table 24h with the rotating speed of 120r/min, after finally clean with deionized water rinsing, be placed in the baking oven dry for standby of 105 DEG C.

Test show that best modified condition is the NaCl solution of 6%, the NaCl solution best results of every 15g natural zeolite consumption 100mL at the temperature of 30 DEG C, simultaneously at matching zeolite in the adsorption test of ammonium nitrogen, modified zeolite adsorptive power under the same terms is better than natural zeolite, at temperature is 30 DEG C, single molecular layer saturated absorption improves more than 34%.

In order to perfection plays the advantage of modified natural zeolite, the present invention is controlling size, the regular shape of zeolite pulverizing, the contact polarity of zeolite granular surface property and nitrogenous fertilizer and modified zeolite particle is improved, by calcining natural zeolite stone, then pulverize, can obtain more regular, the talc particles that size is more homogeneous, carbonized by aerobic, some metal ion compounds in zeolite can be made to resolve into single oxide, are use Na by the cardinal principle of sodium chloride solution immersion treatment zeolite ⁺metal ion process in displacement zeolite, recycling NH ₄ ⁺na is replaced in conjunction with superiority with zeolite ⁺, finally realize adsorption process, the main component of zeolite comprises CaCO ₃, SiO ₂, Al ₂o ₃and H ₂o etc., the zeolite after calcined is easily broken to be decomposed, and the later stage enters in soil course for fertilizer easily decomposes, the ammonium nitrogen of release absorption.

Then at zeolite granular after NaCl solution modification, add certain density acid solution and eluriate zeolite granular, manufacture the surface property particle that shape is more concavo-convex, last at modified zeolite particle when ammonium nitrogen solution carries out Contact-sorption, condition is carried out in supersonic cleaning machine, ultrasonic vibration is conducive to eliminating ammonium nitrogen aqueous solution surface polarity, is conducive to abundant contact to each other.

Beneficial effect of the present invention: by microbiobacterial agent mixed diluting useful for soil; then adsorb with the distinctive modified zeolite particle of the present invention; zeolite granular after modification is not only surperficial rugged; be easy to stop microorganism; centre is also a kind of vesicular structure; the microbial bacteria of absorption obtains a kind of well protection; the high wheat-flour of surface sugar degree after simultaneously having adsorbed is coated; be conducive to provide the carbon source that microorganism is abundant; to in the planting process of corn; permanently effective, microorganism is enriched can have one to utilize fully to the organic matter in soil.
