Abstract
The invention discloses a method for producing a trace element compound fertilizer, and relates to the technical field of chemical industry. The method is mainly technically characterized in that: the ratio of urea to potassium polyphosphate to trace element additive is 85: 13: 2; and the trace element compound fertilizer is formed by mixing and stirring for 3 to 5 minutes in a stirrer, granulating and packing. The trace element compound fertilizer is suitable for crops. The total nutrient of phosphorus and potassium is over 97 percent, wherein the phosphorus and the potassium are complexing agents; and the problem that the conventional trace element compound fertilizer generates insoluble sediments in orthophosphate solution to cause fertilizer invalidation. The trace element compound fertilizer is favorable for plant growth, has improved quality and is a fertilizer with low cost and high benefit.
Description
Technical field
The present invention relates to chemical technology field, be applicable to crop growth fertilizer.
Background technology
The micro-compound powder fertilizer of being sold in the market is mainly by urea and potassium primary phosphate, potassium nitride mixes up in stirring when stirring, add by trace elements such as boron, manganese, zinc, iron, copper again and constitute micro-compound powder fertilizer, this product has been stipulated N+P in the standard of Q/JHY015-1996
2O
5+ K
2The total nutrient of O should 〉=50%, total nitrogen (in N) content 〉=38% wherein, phosphorus (P
2O
5Meter), potassium is (with K
2The O meter) should distinguish 〉=6%, this adds potassium primary phosphate under industrialized condition and potassium nitride just is difficult to reach specification of quality.Because phosphorus potassium total amount is 86% in the potassium primary phosphate, in the potassium nitride (with K
2The O meter) is 60%, when batching, not foot phenomenon will takes place.The shortcoming of this fertilizer is acid strong (pH value is about 4.8), and is unfavorable to plant-growth, and also can produce heavy corrosion to equipment in batch process, if when pH value heightened, trace element can produce precipitation again, causes fertilizer to lose efficacy.
Summary of the invention
Problem to be solved by this invention: a kind of composite fertilizer with trace elements is provided, can make the phosphorus potassium total nutrient in the Rapisol is more than 97%, simultaneously, Rapisol also is a kind of strong complexing agent, it can be dissolved in undissolved trace elements iron, copper, manganese, zinc etc. in the orthophosphate solution, help plant-growth, reach the purpose that improves the composite fertilizer with trace elements quality.
For solving the problems of the technologies described above, the technical solution used in the present invention is: by urea, Rapisol and trace mineral supplement are formed, percentage ratio is counted urea by weight: Rapisol: trace mineral supplement=85%: 13%: 2%, wherein trace element is by ferrous sulfate, manganous sulfate, copper sulfate, zinc sulfate, Sodium orthomolybdate, boric acid, sal epsom is formed, and in pulverizer, pulverize to powdery granularity 42～80 mesh standard sieves, get ferrous sulfate 14% then by weight percentage, manganous sulfate 25%, copper sulfate 3.5%, zinc sulfate 7%, Sodium orthomolybdate 1.2%, boric acid 18%, sal epsom 31.3% evenly constitutes trace mineral supplement through thorough mixing in mixing tank.Urea and Rapisol are all pulverized in pulverizer and are powdery granularity 20～80 mesh standard sieves, and then at normal temperatures and pressures, urea gets 85%, potassiumphosphate gets 13%, trace mineral supplement gets 2%, places stirrer discharging packing after thorough mixing stirs 3～5 minutes, perhaps packs after the granulation.
The invention has the beneficial effects as follows: will have the phosphorus potassium raw material that uses in the micro-compound powder fertilizer now and be improved to the use Rapisol, its phosphorus potassium is always supported Gongwei more than 97%, it is a kind of strong complexing agent, it and trace elements iron, copper, manganese etc. form water soluble complex, be stored among the solution, overcome present throw out fully and the problem that causes fertilizer to lose efficacy.The present invention helps plant-growth, has improved the quality of composite fertilizer with trace elements, is that a kind of production technique is simple, and cost is low, the fertilizer of high efficiency.
Embodiment
Manufacture 1000 gram composite fertilizer with trace elements:
1, makes 20 gram trace mineral supplements, with ferrous sulfate by weight 20 the gram 14% be 2.8 the gram, manganous sulfate by weight 20 the gram 25% get 5 the gram, copper sulfate by weight 20 the gram 3.5% get 0.7 the gram, zinc sulfate by weight 20 the gram 7% get 1.4 the gram, Sodium orthomolybdate by weight 20 the gram 1.2% get 0.24 the gram, boric acid by weight 20 the gram 1.8% get 3.6 the gram, sal epsom by weight 20 grams 31.3% get 6.26 grams, all in pulverizer, pulverize its powdery granularity and reach 60 mesh standard sieves and constitute trace mineral supplement;
2, in pulverizer, pulverize its powdery granularity respectively with 850 gram urea and 130 gram Rapisols and reach 60 mesh standard sieves;
3, the percentage ratio meter is a urea by weight: Rapisol: the ratio of trace mineral supplement=850: 130: 20 drops in the stirrer, through mix stir 3～5 minutes after, can the granulation packing after range estimation mixes, constitute composite fertilizer with trace elements.
The present invention helps plant-growth, has improved the quality of composite fertilizer with trace elements, is that a kind of production technique is simple, and cost is low, the fertilizer of high efficiency.
