Abstract
This invention discloses a method for producing compound boron fertilizer, which is white or light green crystal, and mainly composed of: B 1.0-1.2 wt.%, Zn 0.2-0.5 wt.%, Fe 0.6-1.0 wt.%, and Mg more than 7.0 wt.%. The method comprises: preparing concentrated solution, preparing Zn-Fe mixed solution, preparing semi-finished product, and preparing the final product. The compound boron fertilizer contains Fe and Zn that are necessary for the growth of cotton and rape. Thus, the compound boron fertilizer can compensate the defects of B-Mg fertilizer, promote the development of cotton and rape root systems, improve the ability to absorb nutrients, stimulate the development of gynoecia germens, accelerate the growth, promote photosynthesis, shorten the growth period, advance the mature time, and prevent deficiency symptom. The compound boron fertilizer has increased yield (by 15-25%), simple process, easy application, and no pollution.
Description
Technical field
The present invention relates to a kind of inorganic chemical fertilizer, relate to a kind of boric magnesium fertilizer specifically.
Background technology
The boric acid that utilizes that follows is for a long time produced waste liquid manufacturing crystalline boron fertiliser containing magnesium, be mainly used in cotton, rapeseed cultivation, its consumption is 70% of the total consumption of boric magnesium fertilizer, but because crystalline boron fertiliser containing magnesium composition only contains boron and magnesium, can not satisfy cotton, growth of rape to other micro-demand, cause cotton, yield of rape to be difficult to improve.Have not yet to see the boric magnesium fertilizer that contains zinc, ferro element and the report of manufacturing process.
Summary of the invention
The present invention is directed to the deficiency of present boric magnesium fertilizer composition, propose the compound boron fertilizer and the method for manufacturing technology of a kind of suitable cotton, growth of rape needs.
The technical scheme that the present invention takes is: a kind of compound boron fertilizer and method of manufacturing technology is characterized in that: outward appearance is white or little green crystal, its main component (% is in the element quality): boron 1.0～1.2, zinc 0.2～0.5, iron 0.6～1.0, magnesium＞7.0; Above-mentioned compound boron fertilizer method of manufacturing technology:
Concentrated solution preparation: boric acid waste liquid is neutralized to pH 6～7 with light-burning magnesium powder under stirring at normal temperature, and neutralizer is through the pressure filter press filtration, and gained filtrate is carried out vacuum concentration under 100～110 ℃, 0.3～0.4MPa, makes relative density and be 1.350～1.360 concentrated solution;
Zinc-iron mixed solution preparation: in reactor, add concentrated solution, sulfuric acid, iron filings, oxide powder and zinc in stirring at normal temperature down to the dissolving that fully reacts completely of iron filings, zinc oxide;
The work in-process preparation: the zinc-iron mixed solution is joined in the crystallizer, add concentrated solution, stir, leave standstill crystallization under 20～25 ℃, crystal is separated out after whizzer is isolated secondary mother liquid, and the crystal work in-process are 60～70 ℃ of dryings;
Finished product is composite: in the exsiccant work in-process, add boric acid according to boron content, promptly get compound boron fertilizer after mixing.
The effective constituent of compound boron fertilizer is boric acid, magnesium sulfate heptahydrate, iron vitriol, Zinc Sulphate Heptahydrate, its proportioning is to select according to controlling of production process and field fertilization requirement, when effective composition low, can obtain effect of increasing production though increase rate of fertilizer application, but rate of fertilizer application heightens and adds the fertilising burden, and the low product of production effective constituent, not only invalid components influences packing, the transportation increase cost that fertilizer efficiency also is a product more in the product.Produce high effective constituent product owing to be subjected to the restriction of invalid components content in the raw material, should not improve effective constituent, use pure chemistry product formulated product cost too high, the user is difficult to accept.
Prove that in cotton, rapeseed cultivation field experiment result compound boron fertilizer can promote cotton, rape root prosperity, strengthen it and absorb the nutrient ability, can stimulate the gynoecium ovary development, accelerating growth, improve light and effect, shorten vegetative period, early flowering, solid and ripe, prevent and treat the flower bud of cotton effectively and the flower and the colored and unreal nutritional deficiency disease of rape, its effect of increasing production is than crystalline boron fertiliser containing magnesium improve 15%～25%.
The manufacturing of compound boron fertilizer mainly is the waste liquid that utilizes in the boric acid production process, main component is in the waste liquid: boric acid 4%～5%, sulfuric acid 0.2%～0.5%, magnesium sulfate heptahydrate 23%～28%, its mesoboric acid, sal epsom are the effective constituent of compound boron fertilizer, excessive sulfuric acid adopts the light burnt powder neutralization, and the light burnt powder main component is a magnesium oxide, and its reaction formula is:
MgO+H
2SO
4→MgSO
4+H
2O
The sal epsom that the neutralization back produces is as the effective constituent utilization, waste liquid after the neutralization carries out press filtration to remove water-insoluble impurity, filtrate concentrating removed excessive moisture, makes the filtrate relative density reach 1.350～1.360 (37～38Be °), helps crystallization operation thereafter.
Zinc-iron composition in the compound boron fertilizer is that iron filings and zinc oxide are generated FeSO with sulfuric acid reaction in reactor
4And ZnSO
4, its reaction formula is:
Fe+H
2SO
4→FeSO
4+H
2
ZnO+H
2SO
4→ZnSO
4+H
2O
Above-mentioned reactant mixes with the boric acid waste liquid concentrated solution and carries out crystallization, carries out centrifugation after the crystallization, and drying is carried out in isolated crystallization, and isolated mother liquor contains boric acid and sal epsom, and can to return boric acid waste liquid storage pond stand-by.
The above-mentioned crystallization work in-process that make add a certain amount of boric acid, because boron-containing quantity difference in the raw material waste liquid generally is lower than the effective constituent amount of requirement, thereby need adds boric acid, Mg content is higher in the waste liquid, generally within the effective constituent amount, need not to adjust.
The invention has the beneficial effects as follows: compound boron fertilizer is owing to contain iron, the zinc element of plant growth needs, boron make-up fertiliser containing magnesium defective, can promote cotton rape well developed root system, strengthen it and absorb the nutrient ability, can stimulate the gynoecium ovary development, accelerating growth, improve light and effect, shorten vegetative period, early flowering, solid and ripe, prevent and treat the flower bud of cotton effectively and the flower and the colored and unreal nutritional deficiency disease of rape, its effect of increasing production is than crystalline boron fertiliser containing magnesium improve 15%～25%.
The manufacturing of the compound boron fertilizer of the present invention is based on the waste liquid in the boric acid production, helps environment protection and reduces product cost, and its production technique is simple, and is easy to implement.
