Abstract

The present invention discloses a process for preparing organic balanced compound long-effect fertilizer, which comprises that peat coal, namely brown coal or weathered coal, a microporous carrier, ammonium chemical fertilizer, etc. are ammonified together so that the raw material is converted into organic fertilizer, such as ammonium humate, phosphorus humate, potassium humate, etc., and the organic fertilizer is stored in the microporous carrier. The fertilizer is long-effect fertilizer rich in trace elements such as nitrogen, phosphorus and potassium, volatilization can not occur easily, and the fertilizer can also improve soil.

Description

The preparation technology of organic balanced compound long-acting fertilizer

The present invention relates to a kind of preparation technology of organic balanced compound long-acting fertilizer.

At present, the fertilizer that use in the rural area has two big classes, and a class is traditional organic fertilizer, though this class fertilizer is organic many, but fertilizer efficiency is slow, uses unhygienicly, and also inconvenient, another kind of is chemical fertilizer, fertilizer efficiency is fast, and is convenient, healthy, but makes soil compaction easily, easy molten solid carbon dioxide and running off.Also easy volatilization losses such as some ammonium class chemical fertilizer such as carbon ammonium.

The object of the present invention is to provide a kind of easy to use, health, contain organic abundant, fertilizer efficiency not only soon but also long, be not easy volatilization and run off, also the preparation technology of the organic compound long-acting fertilizer that can improve the soil.

The object of the present invention is achieved like this:

Following raw material is selected in the long lasting preparation of organic plural equilibrium for use:

Be rich in the coal (mud coal or brown coal, weathered coal) of humic acids

Contain micropore pelletizing carrier: as flyash, Brick Kiln ash, burnt dust-ashes etc.

Ammonium class chemical fertilizer is as ammoniacal liquor, volatile salt etc.Can also select calcium, magnesium, phosphorus composite fertilizer for use, oil cake (as rubsen cake, oil extracted from rice husks cake etc.) can also replace containing the coal class of humic acids with animal waste or biogas residue.

Preparation technology may further comprise the steps:

1〉system material: solid material is dried to water content and is less than or equal to 20%,

Cross the 60-80 mesh sieve;

2〉close material: by coal: contain porous carrier: ammonium class chemical fertilizer:

Oil cake: calcium, magnesium, phosphorus composite fertilizer=35～45:

40～50: 5～10: 0～10: 0～10 mixed is even;

3〉ammonification: control raw material water content is that about 40% to carry out ammonification synthetic;

4〉slaking: airtight 4～7 days begin to descend the expression ammonification to temperature

React completely;

5〉regulate pH value 6.5～7.5 with white lime;

In the raw material that the present invention selects for use, because mud coal (or brown coal, weathered coal) humic acids content is very high in (contains humic acids about 67% as weathered coal, mud coal contains humic acids 15～40%), when it and ammonium class chemical fertilizer (or calcium, magnesium, phosphorus composite fertilizer and other fertilizer) mix after, chemical reaction just takes place, humic acids changes into ammonium humate with ammonium salt chemical combination respectively, close with phosphatization and to change into phosphorus humic acid phosphorus, change into potassium humate etc. with potassium chemical combination, again because the present invention adds the carrier that granule contains micropore, these raw materials itself contain nitrogen, phosphorus, potassium and other trace elements are through producing the vaporization micropore after the calcination again, so not only itself be the protoplasm of fertilizer, more because contained micropore has adsorption, and have solid ammonia to protect the function of phosphorus, fertilizer is stored in the carrier over a long time, just dispensing is come out when the crop growth needs, among crop will be stored in porous carrier when not required, so this fertilizer efficiency is very long, nitrogen, phosphorus, potassium, trace element is all very complete, is not easy volatilization and loss.Because this fertilizer contains abundant organic matter, helps the growth of plant, can improve the soil again owing to being rich in organic matter and micelle grain support material, be a kind of ideal organic balanced compound long-acting fertilizer therefore.

Embodiment:

1. system is expected: mud coal and brick slag ash, be dried to water content 20%, and separated pulverizing is crossed 60 mesh sieves;

2. with the mud coal 40kg that pulverizes, brick slag ash particulate 50kg, bicarbonate of ammonia 6kg, the adding retort stirs;

3. ammonification: add water 20kg, stirring, it is synthetic to carry out ammonification;

4. slaking: airtight 5-7 days, to react completely (temperature begins to descend);

5. regulate PH=7 with white lime.

Claims (1)

1, a kind of preparation technology of organic balanced compound long-acting fertilizer is characterized in that may further comprise the steps:

1〉system material: solid material is dried to water content and is less than or equal to 20%.Cross the 60-80 mesh sieve;

2) close material: by coal: contain porous carrier: ammonium class chemical fertilizer:

Oil cake: calcium, magnesium, phosphorus composite fertilizer=35-45:

The ratio of 40-50: 5-10: 0-10: 0-10 adds raw material

And mix;

3〉ammonification: control raw material water content is that about 40% to carry out ammonification synthetic;

4〉slaking: airtight 4-7 days begin decline to temperature and represent aminating reaction

Fully;

5〉regulate PH6.5-7.5 with white lime.
