Abstract

A nutritive improver for soil is prepared from the activated carbon as carrier rejected in preparing cystine and the chelate of amino acids and trace elements. It can provide trace nutrients for crops, adsorb the toxic and harmful substances from soil, increase soil temp and water-bearing power, improve air permeability, and regulate the absorption of fertilizer for crops.

Description

A kind of soil nutrient modifying agent

The present invention relates to a kind of soil nutrient modifying agent.

Active outbreak is widely used in numerous areas such as medicine, food, chemical industry for a kind of discoloring agent has advantages such as good decolorizing effect, nontoxic, easy filtering separation because of it.The most organic compounds containing nitrogens of coloring matter that gac is adsorbed for having no side effect, these materials have certain fertilizer efficiency to farm crop, regeneration of activated carbon is to be heated decomposition, recover active after treatment, but because of the too late original gac of effect choosing of regenerated carbon, the high complex disposal process of regeneration cost is so discarded gac is all given it up, not only waste this precious resources, and serious environment pollution.

This technology be will not contain Toxic matter from sugar refinery, amino acid factory etc. discarded gac as carrier, microelement chelate in the amino acid is added drying behind the stirring and evenly mixing, pulverizing, granulation, oven dry forms.Purpose is to utilize the adsorptivity and the nutrition of discarded gac, adsorbs various nutrient elements, and reaches the effect of slowly-releasing.Its advantage is: 1, utilize waste resource, reduce environmental pollution, making it turns waste into wealth, and turns harm into good.2, gac has very strong adsorption, with its sorbent material as trace element in the amino acid, plays tangible slow releasing function, reduces and runs off the utilization ratio of little fertilizer in the raising.3, toxin and the objectionable impurities in the discarded adsorbable soil of gac.4, have the biological fixation effect that promotes nitrogen, make organonitrogen be converted into ammonia and nitrate faster.5, can improve soil temperature, increase the water capacity and the ventilation property of soil.

Demand according to rich scarce and different crops centering trace element micro-in the different soil, the ratio of trace element in the adjusting, production method is as follows: 1, the inorganic salt with trace element are dissolved in the compounded amino acid mother liquor, rub than being trace element: amino acid=1: 1.5-2.5, be heated to boiling 2-4 hour, generate trace element chelated liquid in the aminoacids complex.2, will discard gac and add the trace element chelated liquid of aminoacids complex, and make it to become thick pulpous state, part by weight is discarded gac: the trace element chelated liquid of aminoacids complex=1: 1.5-2.0.3, above-mentioned slurry is used fluidized drying or box-type drying dry to moisture content and be 5-10%, be crushed to 80 orders, be finished product.Also can add attapulgite dries behind disk granulation or extruder grain and makes particulate state.

Embodiment 1

Getting the mother liquor of discharging in the Gelucystine production is Moriamin S 1060Kg, adds in 2000 liters of enamel reaction stills, stirs to add ZnSO down ₄7H ₂O226Kg, heating makes it dissolving, regulates PH=5.5, continues to be heated to boiling, chelatropic reaction adds after 4 hours water content be 40% amino acid decolouring with discarding gac 800Kg, continue to stir to pulpous state, emit oven dry, be crushed to 80 orders and be finished product.

Embodiment 2

Get useless chicken feather 1000Kg, add in 3000 liters of enamel reaction stills, adding concentration is 35% dilution heat of sulfuric acid 2000Kg, is heated to and boils, and hydrolysis was cooled to below 60 degree after 6 hours, added NH ₄HCO ₃PH=5.0 is regulated in neutralization, adds FeSO ₄900Kg, chelatropic reaction 6 hours generates iron-amino acid chelate, puts into another 5000 liters of steel basins, drops into the discarded gac 1500Kg of sugar refinery moisture 50%, stirs evenly the back oven dry, pulverizes, and is powdery soil nutrition modifying agent.

Embodiment 3

The mother liquor 1000Kg that gets Gelucystine factory adds in 2000 liters of enamel reaction stills, adds ZnSO successively ₄7H ₂O 60Kg, FeSO ₄7H ₂O 50Kg, MnSO ₄H ₂O50Kg, CuSO ₄5H ₂O20Kg, MgSO ₄7H ₂O20Kg dissolving is heated to boiling, keeps 4 hours, puts into steel basin, and adding 1000Kg moisture is the decolour discarded gac of usefulness of 50% discarded Gelucystine crude product.Stir to pulpous state, drying, pulverizing, granulation, oven dry are granular soil nutrient modifying agent.

Claims

1, a kind of soil nutrient modifying agent is to be carrier with the discarded gac that is used to decolour in the Gelucystine production, adds microelement chelate in the amino acid, drying, pulverizes granulation and forms.

2, discarded gac according to claim 1 is from thick and two thick Gelucystine bleaching process.

3, microelement chelate in the amino acid according to claim 1, be with a kind of among micro-Fe, Cu, Mn, Zn, Ca, the Mg or the mixed amino acid mother liquor chelating that produces in all producing, generate microelement chelate liquid in the amino acid with Gelucystine.

4, production method according to claim 1 is that 1 mole middle micro-inorganic salt directly are dissolved in the amino acid mother liquor of 1.5-2.5 mole, ebuillition of heated carried out chelating to 2-4 hour, microelement chelate in the amino acid that generates is added in the discarded gac through concentrating, carry out drying after being mixed with pulpous state, to water content be 10-20%, carry out extruder grain, be finished product after the oven dry.

5, finished product according to claim 4 can be that powdery also can be granular.

6, microelement chelate is that the micro-inorganic salt of adding carry out chelating after adding sulfuric acid or hydrochloric acid hydrolysis with discarded albumen in the amino acid according to claim 1, and uses NH ₄HCO ₃Or NH ₃H ₂O neutralizes and obtains.
