Description

A kind of long-acting zinc supplement fertilizer

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of long-acting zinc supplement 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 in agricultural production Important fertilizer, fertilizer has the multiple advantages such as nutrition complete, improvement soil, raising utilization rate of fertilizer.But it is 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 into air without control In, cause air pollution；Two is to meet the demand that soil pollution is repaired, and simple soil structure improved addictive cannot realize polluting The raising of soil crop quality；Three is that nutrient supply is slow, though longer than common fertilizer efficiency, but be difficult to meet plant vigorous growth Time demand to nutrient；Four is that fertilizer volume is big, transports and stores inconvenience；Five be for special soil environment such as soda acid, drought wet, Soil that Partial Elements lacks and the nutrient demand of concrete crop without effectively for.

On the sieve of matured compost, coarse granule quality is soft, short texture, has stronger absorbability, in change of moisture content relatively Remain to keep the gas diffusion of certain porosity, beneficially cover layer time big, contain simultaneously a large amount of microorganism such as methane-oxidizing bacteria, Nitrobacterias etc., therefore, the discharge utilizing the upper coarse granule of matured compost sieve to reduce Composting Process greenhouse gases simply and is prone to Realize.

Use dodecyldimethylammonium hydroxide inner salt and POLYSORBATE 80 that fertiliser granulates is modified, can obtain simultaneously there is alkyl The fertiliser granulates of hydrophobic carbochain and respectively band positive and negative charge hydrophilic group structure, in the premise retaining heavy metal absorption property Under, 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 long-acting zinc supplement fertilizer.

The present invention is achieved by the following technical solutions:

A kind of long-acting zinc supplement fertilizer, is prepared by the raw materials in: Zinc residue 22-24, fish flour 10-12, cottonseed meal 30- 34, soil level polyglutamic acid 3-5, alimentary acetic acid 5-6, distiller's grains of beer 18-20, amino-acid zinc 2.4-2.6, anhydrous nitric acid zinc 2-3, heap Fertile coarse granule 16-18, sunflower straw 20-22, dodecyldimethylammonium hydroxide inner salt 1.6-1.8, POLYSORBATE 80 1.2-1.4, kaolinite Soil 15-16, water are appropriate.

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

Specifically comprising the following steps that of the preparation method of described long-acting zinc supplement fertilizer

(1) Zinc residue, fish flour, cottonseed meal mixing are placed in fermentation vat and carry out compost fermentation, and by uniform for compost coarse granule It is laid in compost surface, keeps fermentation heap water content at 60-65%, after fermenting 13-15 days, add soil level polyglutamic acid, food With acetic acid, distiller's grains of beer, then carry out turning, upper strata coarse granule mixed homogeneously with lower floor fermentation material, continue fermentation 20-24 days, Period carries out 2-3 turning again, obtains fermentation material standby；

(2) clean for sunflower straw drip washing post-drying is pulverized, be placed in high temperature furnace, under anaerobic with 15-20 DEG C every point Speed be warming up to 600 DEG C, and at this temperature insulation 135-150 minute, take out after being cooled to room temperature biomass carbon is standby；

(3) Kaolin is put in high temperature furnace, rise to 400-410 DEG C with the speed of 30 DEG C every point, come out of the stove after calcining 2 hours cold But, 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 kaolin powder being mixed, and heat up To 40-45 DEG C, it is being stirred continuously lower addition dodecyldimethylammonium hydroxide inner salt, is filtering after being incubated 3-4 hour and remove solution, natural Add 10-12 times of quality water after Feng Ganing, add POLYSORBATE 80 after mix homogeneously, aqueous solution is heated to 49-51 DEG C, constantly Stir and be incubated 120-130 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, amino-acid zinc, anhydrous nitric acid zinc with 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 can not only be improved Physical arrangement, improves composting production rotten degree, utilizes its open structure and stronger adsorptivity simultaneously, reduce earlier fermentation ammonia with And the discharge of the gas such as later stage methane, decrease the nitrogen loss of fermentation while protecting environment, improve fertilizer fertility.

Preparation process utilize the dodecyldimethylammonium hydroxide inner salt of easily biological-degradable and POLYSORBATE 80 to charcoal-Kaolin Composite interstitial substance is modified, and can not only improve the cation exchange capacity (CEC) of soil, has outstanding organic pollution and a huge sum of money simultaneously Belong to the dual absorbability of pollutant, improve the safety of soil plantation, add the surcharge of fertilizer.

The fertilizer of the present invention utilizes the raw materials such as Zinc residue, amino-acid zinc, anhydrous nitric acid zinc, in inorganic and organic direction All improve Zinc content of soil, and the Chelating state easily absorbed with plant exists, zinc long-term holding in soil can not only be made effective State, overcomes single Inorganic Zn fertilizer simultaneously and is fixed easily in soil and the problem of plant absorption difficulty, it is achieved that the length of crop Phase zinc supplement effect.
