Abstract

The invention discloses a high-calcium organic fertilizer. The high-calcium organic fertilizer is prepared from the following raw materials in parts by weight: 12 to 15 parts of shell meal, 33 to 35 parts of bagasse, 16 to 18 parts of fish bone meal, 3.4 to 3.6 parts of chitin, 15 to 16 parts of soybean flour, 3 to 4 parts of chitosan oligosaccharide, 4 to 5 parts of limestone powder, 5 to 6 parts of calcium chloride, 25 to 27 parts of composted rough grains, 22 to 24 parts of sunflower straws, 1.2 to 1.4 parts of dodecyl dimethyl betaine, 0.9 to 1.1 parts of Tween 80, 16 to 19 parts of kaolin and a proper amount of water. The high-calcium raw materials including the shell meal, the fish bone meal and the like are added into the organic fertilizer and are combined with the addition of the chitin, the chitosan oligosaccharide and the like and fermentation treatment of microorganisms, so that a lot of soluble calcium salts capable of being absorbed and utilized by plants can be formed; a unique process design of fertilizer grain production is adopted, and thus the conversion rate of effective components in the fertilizer is great, so that the high-calcium organic fertilizer has a relatively good utilization effect on high-calcium crop production.

Description

A kind of high calcium fertilizer

Technical field

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

The present invention is achieved by the following technical solutions:

A kind of high calcium fertilizer, is prepared by the raw materials in: conch meal 12-15, bagasse 33-35, fishbone powder 16- 18, chitin 3.4-3.6, Semen sojae atricolor powder 15-16, oligochitosan 3-4, agstone 4-5, calcium chloride 5-6, compost coarse granule 25-27, Sunflower straw 22-24, dodecyldimethylammonium hydroxide inner salt 1.2-1.4, POLYSORBATE 80 0.9-1.1, Kaolin 16-19, water are suitable Amount.

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 high calcium fertilizer

(1) conch meal, bagasse, fishbone powder 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 chitin, Semen sojae atricolor powder, shell after fermenting 13-15 days Oligosaccharide, then carries out turning, is mixed homogeneously with lower floor fermentation material by upper strata coarse granule, continues fermentation 20-24 days, and period is carried out again 2-3 turning, 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 140-160 minute, take out after being cooled to room temperature biomass carbon is standby；

(3) Kaolin is put in high temperature furnace, rise to 390-410 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 40-42 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 53-55 DEG C, constantly Stir and be incubated 80-100 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, agstone, calcium chloride 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-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 with the addition of the high calcium raw material such as conch meal, fishbone powder, in conjunction with the addition of chitin, oligochitosan etc. And the fermentation process of microorganism, the soluble calcium salt can being absorbed and used by plants in a large number can be formed, produce through fertiliser granulates again Unique technological design, makes the conversion ratio of effective ingredient in fertilizer big, thus has production high calcium crop and preferably use effect Really.

Detailed description of the invention
