Description

A kind of lignin particles fertilizer

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of lignin particles 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 lignin particles fertilizer.

The present invention is achieved by the following technical solutions:

A kind of lignin particles fertilizer, is prepared by the raw materials in: oil foot 23-26, broad-leaved wood flour 32-34, Semen Fagopyri Esculenti Shell 14-16, calcium lignosulfonate 5-7, Oleum Glycines 4.3-4.7, xylose powder 3.5-3.8, Pulvis Talci 3-4, MAP 8-10, compost Coarse granule 25-26, sunflower straw 37-39, dodecyldimethylammonium hydroxide inner salt 1.6-1.8, POLYSORBATE 80 1.2-1.3, bentonite 18-20, 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 lignin particles fertilizer

(1) oil foot, broad-leaved wood flour, Buckwheat shell mixing are placed in fermentation vat and carry out compost fermentation, and by equal for compost coarse granule The even compost surface that is laid in, keeps fermentation heap water content at 60-65%, adds calcium lignosulfonate, bean after fermenting 18-20 days Oil, xylose powder, then carry out turning, is mixed homogeneously with lower floor fermentation material by upper strata coarse granule, continues to ferment 20-24 days, period Carry out 2-3 turning again, obtain 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 100-120 minute, take out after being cooled to room temperature biomass carbon is standby；

(3) bentonite is put in high temperature furnace, rise to 380-400 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 bentonite powder being mixed, and heat up To 40-42 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 46-48 DEG C, constantly Stir and be 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, Pulvis Talci, MAP and its Remaining leftover materials mixing granulation, obtains 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-bentonite 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 is according to the slower characteristic of the biodegradation rate of lignin, in conjunction with straw biomass charcoal with wealthy Leaf wood flour, the addition of calcium lignosulfonate, it is achieved that the nutrient slowly-released effect of fertilizer, by the slow degraded of fertilizer, both to plant The form that thing easily absorbs releases macronutrient, turn avoid and uses the excessive element pollution problem that common fertilizer occurs, All have in terms of fertilizer efficiency and environmental protection and preferably apply effect.

Detailed description of the invention

A kind of lignin particles fertilizer, is made up of the raw material of following weight portion (kg): oil foot 23, broad-leaved wood flour 32, buckwheat Wheat husk 14, calcium lignosulfonate 5, Oleum Glycines 4.3, xylose powder 3.5, Pulvis Talci 3, MAP 8, compost coarse granule 25, Helianthi Straw 37, dodecyldimethylammonium hydroxide inner salt 1.6, POLYSORBATE 80 1.2, bentonite 18, water are appropriate.
