Abstract
The invention relates to an efficient high-concentration sulfur-based compound fertilizer containing poly-gamma-glutamic acid, which is prepared from urea, phosphoric acid, potassium chloride, potassium sulfate, sulfuric acid, gas ammonia and poly-gamma-glutamic acid, and also comprises a water-retaining agent. A production process of the efficient high-concentration sulfur-based compound fertilizer comprises the steps of: A, preparing a mixed acid; B, neutralizing; C, pelleting and forming; D, preparing monoammonium phosphate; E, supplementing potassium; and F, supplementing nitrogen. The invention has the advantage of being capable of manufacturing the efficient high-concentration sulfur-based compound fertilizer containing the poly-gamma-glutamic acid, with the proportion of N:P:K of 17:17:17. Meanwhile, a poly-gamma-glutamic acid fertilizer synergist is added in the production process and used as a fertilizer absorbing promoting agent used on single nitrogen or phosphorus or potassium or the combination of the nitrogen and the phosphorus as well as the potassium. In addition, the water-remaining agent is added for increasing the water-retaining effect.
Description
Technical field
The present invention relates to the farmland fertilizer manufacture field.
Background technology
At present, known S-based compound fertilizer is that raw material is produced General N by Repone K, gas ammonia, urea, sulfuric acid, phosphoric acid: the P:K ratio is 14:16:15 or 15:15:15, and the N:P:K ratio does not reach 17:17:17, thereby fertilizer efficiency is not high enough.
Summary of the invention
Purpose of the present invention is exactly for known S-based compound fertilizer and the above-mentioned deficiency of production technique, and a kind of high-efficiency high-concentration sulphur based complex fertilizer that contains poly-gamma-glutamic acid is provided, it is made by urea, phosphoric acid, Repone K, vitriolate of tartar, sulfuric acid, gas ammonia, poly-gamma-glutamic acid; Its each component weight part proportioning is:
The urea 18.63 20% phosphatase 79 2.72-97.36 that contain N amount 46% contain K
2The Repone K 10 of O 60%
Vitriolate of tartar 20.37 98% sulfuric acid 6.00 gas ammonias 9.20
Poly-gamma-glutamic acid 0.05-0.5.
It also has water-holding agent, and its formulation by weight is:
The urea 18.63 20% phosphatase 79 2.72-97.36 that contain N amount 46% contain K
2The Repone K 10 of O 60%
Vitriolate of tartar 20.37 98% sulfuric acid 6.00 gas ammonias 9.20
Poly-gamma-glutamic acid 0.05-0.5 water-holding agent 2-2.5.
Its production craft step is:
A, produce nitration mixture: with containing K
2After the Repone K of O 60% and 98% sulfuric acid are mixed and made into sal enixum, again and 20% phosphoric acid after the peroxophosphoric acid quality control mix, namely make nitration mixture;
B, neutralization reaction: with above-mentioned nitration mixture and gas ammonia at tubular reactor after the secondary neutralization reaction, the inflow place groove forms slip;
C, granulating and forming: above-mentioned slip is sent into the moulding of drying machine drying-granulating;
D, preparing phosphoric acid one ammonium: 20% phosphoric acid and gas ammonia after the tubular reactor neutralization reaction, are generated the monoammonium phosphate slip, send into granulating and forming;
E, mend potassium: through anti-material system with vitriolate of tartar, contain K
2The Repone K of O60%, ton poly-gamma-glutamic acid and water-holding agent join respectively the tablets press granulating;
F, mend nitrogen: urea is fused into slurry under 120 ℃ of temperature, when the particle of drying-granulating moulding enters cooling cylinder, by shurry pump the urea slurry is got final product from the particle surface that the cooling machine head of cooling cylinder is injected into the drying-granulating moulding.
Advantage of the present invention is: can produce the N:P:K ratio is the high-efficiency high-concentration sulphur based complex fertilizer that contains poly-gamma-glutamic acid of 17:17:17.In complete processing, added simultaneously poly-gamma-glutamic acid fertilizer
Synergistic agent is used for nitrogen, phosphorus, potassium single-element or its fertilizer absorption accelerator that is used in combination; Poly-gamma-glutamic acid collection slowly-releasing and synergy dual-use function not only have the multi-efficiencies such as the fertilizer loss of slowing down, drought-resistant water-preserving, disease-resistant yield-increasing, and have that production cost is low, superior performance, easy to use.Beneficial effect of the present invention is: can be degraded by Soil Microorganism, have the value of environmental protection; Can guarantee in the normal situation of plant-growth, use poly-gamma-glutamic acid 20-100 gram for every mu, can reduce the normal usage quantity 10-30% of fertilizer, more than the volume increase 10-30%, improve simultaneously the quality of crop, improve nitrogen in the crop, phosphorus, potassium content.Can add water-holding agent in addition, to increase the water conservation effect.
Embodiment
