Description

A kind of organic and inorganic compound fertilizer

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of organic and inorganic compound fertilizer.

Background technology

Along with the level of modernization of agricultural is more and more higher, fertilizer the most gradually replaces common chemical fertilizer, becomes fertilizer important in agricultural production, and fertilizer has the multiple advantages such as nutrition complete, improvement soil, raising utilization rate of fertilizer.But presently commercially available fertilizer suffers from many defects, and one is easily to produce a large amount of greenhouse gases in preparation process, and is discharged in air without control, causes air pollution；Two is to meet the demand that soil pollution is repaired, and simple soil structure improved addictive cannot realize the raising of contaminated soil crop quality；Three is that nutrient supply is slow, though longer than common fertilizer efficiency, but demand to nutrient when being difficult to meet plant vigorous growth；Four is that fertilizer volume is big, transports and stores inconvenience；Five be soil and the concrete crop that special soil environment such as soda acid, wet, the Partial Elements of drought are lacked nutrient demand without effectively for.

On the sieve of matured compost, coarse granule quality is soft, short texture, there is stronger absorbability, remain to keep certain porosity when change of moisture content is bigger, it is beneficial to the gas diffusion of cover layer, containing a large amount of microorganism such as methane-oxidizing bacteria, nitrobacteria etc., therefore, the discharge utilizing the upper coarse granule of matured compost sieve to reduce Composting Process greenhouse gases simply and is easily achieved simultaneously.

Use dodecyldimethylammonium hydroxide inner salt and POLYSORBATE 80 that fertiliser granulates is modified, the fertiliser granulates with the hydrophobic carbochain of alkyl and band positive and negative charge hydrophilic group structure respectively can be obtained simultaneously, on the premise of retaining heavy metal absorption property, further increasing the absorbability to organic pollution, the preparation for fertilizer opens new approach.

Summary of the invention

The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of organic and inorganic compound fertilizer.

The present invention is achieved by the following technical solutions:

A kind of organic and inorganic compound fertilizer, is prepared by the raw materials in: pine needle powder 9-11, lard stearin 25-28, leaf bran 23-24, wheat gluten flour 4-5, vinegar 14-16, ferric citrate 2.4-2.6, potassium carbonate 4-6, compost coarse granule 16-18, sunflower straw 22-25, dodecyldimethylammonium hydroxide inner salt 1.3-1.5, POLYSORBATE 80 0.7-0.9, bentonite 14-16, water are appropriate.

Described compost coarse granule is through screening after compost maturity, as coarse granule on the particle diameter of the offal treatment sieve more than 10mm.

Specifically comprising the following steps that of the preparation method of described organic and inorganic compound fertilizer

(1) pine needle powder, lard stearin, the mixing of leaf bran are placed in fermentation vat and carry out compost fermentation, and by evenly laid out for compost coarse granule on compost surface, keep fermentation heap water content at 60-65%, wheat gluten flour, vinegar is added after fermenting 13-15 days, then carry out turning, upper strata coarse granule is mixed homogeneously with lower floor fermentation material, continue fermentation 26-28 days, period carries out 2-3 turning again, obtains fermentation material standby；

(2) by clean for sunflower straw drip washing post-drying pulverize, be placed in high temperature furnace, be warming up to 600 DEG C with the speed of 12-15 DEG C every point under anaerobic, and at this temperature insulation 120-150 minute, take out after being cooled to room temperature biomass carbon is standby；

(3) putting in high temperature furnace by bentonite, rise to 400-410 DEG C with the speed of 30 DEG C every point, cooling of coming out of the stove after calcining 2 hours, levigate 80-100 mesh sieve the most excessively is standby；

(4) with 10 times of quality water mixings after step 2 gained biomass carbon and step 3 gained bentonite powder being mixed, and it is warming up to 40-42 DEG C, it is being stirred continuously lower addition dodecyldimethylammonium hydroxide inner salt, filter after being incubated 3-4 hour and remove solution, after natural air drying, add 10-12 times of quality water, after mix homogeneously, add POLYSORBATE 80, aqueous solution is heated to 50-53 DEG C, it is stirred continuously and is incubated 90-120 minute, be filtered to remove solution afterwards, by mixture dry for standby at 60-65 DEG C；

(5) by step 1 gained fermentation material dry after pulverize, and with step 4 gained mixture, ferric citrate, potassium carbonate and remaining leftover materials mixing granulation, obtain fertilizer of the present invention.

The invention have the advantage that

Preparation process use compost coarse granule cover in advance; the compost fermentation mode of later stage mixing; compost physical arrangement can not only be improved; improve composting production rotten degree; utilize its open structure and stronger adsorptivity simultaneously; reduce the discharge of the gas such as earlier fermentation ammonia and later stage methane, while protecting environment, decrease the nitrogen loss of fermentation, improve fertilizer fertility.

Charcoal-bentonite composite interstitial substance is modified by the dodecyldimethylammonium hydroxide inner salt and the POLYSORBATE 80 that utilize easily biological-degradable in preparation process, the cation exchange capacity (CEC) of soil can not only be improved, there is outstanding organic pollution and the dual absorbability of heavy metal contaminants simultaneously, improve the safety of soil plantation, add the surcharge of fertilizer.

The fertilizer of the present invention has that fertilizer efficiency is high, feature rich in various trace elements, inorganic fertilizer is reasonably with the addition of on the basis of a large amount of organic matter material such as lard stearin, leaf bran, wheat gluten flour, the quick-acting of inorganic fertilizer are made to organically combine with farming area in Zuogong soil with the long-acting of organic fertilizer and offer plant nutrient, it is achieved that increasing crop yield, quality of agricultural product promote and the optimization improving effect of soil.
