Abstract
The present invention relates to chemical technology. Technologically, the composite fertilizer is produced by mixing urea, polypotassium phosphate and trace element additive in the ratio of 85 to 13 to 2 through stirring for 3-5 min, pelletizing and packing. It is suitable for crop and its potassium phosphate is complex. Its trace elements will not be deactivated, so that the composite fertilizer has high quality and is suitable for promoting plant growth.
Description
Composite fertilizer with trace elements of the present invention relates to chemical technology field, is applicable to crop growth fertilizer.
At present commercially available micro-compound powder fertilizer is mainly by urea and potassium primary phosphate, potassium nitride mixes up in stirrer 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
2O 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, the problem that causes fertilizer to lose efficacy.
The purpose of this invention is to provide a kind of composite fertilizer with trace elements, it is more than 97% that this fertilizer can make the phosphorus potassium total nutrient in the Rapisol, 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.
The design (Fig. 1) of the no plain compound fertilizer of the present invention's trace 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, sal epsom, Sodium orthomolybdate, boric acid is formed, and pulverizing is powdery granularity 42～80 mesh standard sieves in pulverizer, getting ferrous sulfate then by weight percentage is 14%, manganous sulfate is 25%, copper sulfate is 3.5%, zinc sulfate is 7%, sal epsom is 31.3%, Sodium orthomolybdate is 1.2%, and boric acid is 18% evenly to constitute 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 effect of composite fertilizer with trace elements of the present invention is compared with prior art: be that the phosphorus potassium raw material that will use in the existing micro-compound powder fertilizer is 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 existing 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.
Fig. 1 is the process flow sheet of composite fertilizer with trace elements of the present invention.
The embodiment of composite fertilizer with trace elements of the present invention manufactures 1000 gram composite fertilizer with trace elements: 1, make 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 grams 1.8% get 3.6 grams, sal epsom is 31.3% the getting 6.26 grams and all pulverize its powdery granularity reach 60 mesh standard sieves and constitute trace mineral supplement in pulverizer of 20 grams by weight.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.
Claims (3)
1, a kind of production method of composite fertilizer with trace elements is characterized in that percentage ratio meter by weight, urea: Rapisol: trace mineral supplement=85%: 13%: 2%, mix the method that stirred 3～5 minutes at normal temperatures and pressures.
2, a kind of composite fertilizer with trace elements is characterized in that the composition (by weight percentage) of this fertilizer is as follows:
Urea 850
Rapisol 130
Trace mineral supplement 20
3, the production method of composite fertilizer with trace elements according to claim 1, the powdery granularity that it is characterized in that urea, Rapisol is 20～80 mesh standard sieves, and the powdery granularity of micro-ferrous sulfate, manganous sulfate, copper sulfate, zinc sulfate, Sodium orthomolybdate, boric acid, sal epsom is 42～80 mesh standard sieves.
