Description
Technical field
The present invention relates to a kind of compound manure, especially a kind of phosphoric acid sulphur ammonium compound fertilizer material that can invalid phosphorus, potassium in the soil be decomposed into available phosphorus, potassium and trace element.
Background technology
Scarce phosphorus, potassium deficiency are ubiquitous problems in the world wide in the soil, and it has seriously limited output and the distribution of crop.Along with the population growth to the continuous increase of grain demand and the energy dilemma that causes thus, this trend also will constantly increase the weight of.Phosphorus, potassium are the indispensable nutritive elements of growth and development of plants, are the important component parts of plant.Total phosphorus, potassium do not lack in world's overwhelming majority soil, and its content: phosphorus is generally 0.1～0.2% (with P
2O
5Meter), potassium is generally 1～2.5% (with K
2O counts), high individually reaches 4%.99% phosphorus potassium is present in tricalcium phosphate and the silicate minerals with invalid form in China's agricultural land soil, can not be by the plant absorbing utilization.How invalid phosphorus, potassium element in the soil are converted into can be by available state phosphorus, the potassium of plant absorbing utilization for this reason, and the usage quantity that reduces chemical fertilizer becomes the important topic of scientific research.People adopt several different methods to improve the utilization ratio of phosphorus, potassium; As excavating plant self potentiality; Raising is to the absorbing of the indissoluble attitude phosphorus in the soil, potassium the time; Adopt bio-bacterial manures such as phosphate solubilizing bacteria, potassium solubilizing bacteria that indissoluble attitude phosphorus, potassium are converted into plant again and can absorb form, improve the content of available phosphorus, potassium in the soil, increase crop yield.Be to guarantee the growth needs of crop, mostly through use soluble phosphoric manure, potash fertilizer is that plant provides available phosphorus, potassium, to satisfy the needs of plant growth.But the phosphate radical chemical property is active, the Ca after applying in the very fast and soil
2+, Fe
3+, Fe

3+In conjunction with, the phosphoric acid salt of formation indissoluble.Bio-bacterial manures such as existing phosphate solubilizing bacteria, potassium solubilizing bacteria thalline under field conditions (factors) are easy to death, and the ability of phosphorus decomposing, potassium decomposing is not ideal enough, are difficult to satisfy the needs of agriculture prodn.People need a kind of method that can decomposite the needed phosphorus of plant-growth, potassium and trace element effectively; Through a large amount of research trials; Proof is in dissimilar soil; Sulfuric acid, phosphoric acid, nitric acid, hydrochloric acid etc. can decomposite the needed phosphorus of enough plant growths, potassium and trace element effectively, and use can not make the soil souring in acid and subacidity soil.But sulfuric acid, nitric acid, hydrochloric acid exist when using consumption big and be corrosive, cost is high, volatile, be unfavorable for promoting.
Summary of the invention
The objective of the invention is in order to overcome the deficiency that above-mentioned prior art exists; A kind of phosphoric acid sulphur ammonium compound fertilizer material that can decompose phosphorus in the soil, potassium is provided; The produced meltbility compound manure of technology such as it melts through being mixed, heating altogether, granulation; Not only reasonable recipe, production technique are simple, and can be the effective constituent that crop can absorb with invalid phosphorus, potassium element decomposition and inversion in the soil after using.
The technical scheme that the present invention adopted is to realize like this; It is to be processed by the raw material of following weight parts meter: 3～15 parts of concentration 75～95% phosphoric acid, 2～18 parts in ammonium sulfate; Its preparation method is that 2～18 parts in the ammonium sulfate of weight part meter is added in 3～15 parts of concentration 75～95% phosphoric acid; Under 120～140 ℃, mix; Treat to obtain after ammonium sulfate all dissolves the phosphoric acid sulphur ammonium fused matter material of uniformity in phosphoric acid, the fused matter material that is mixed is sent into granulation in the prilling granulator, the material after the granulation obtains particulate state phosphoric acid sulphur ammonium compound fertilizer material through cooling; Or with carrying out combination reaction in monoammonium phosphate or the diammonium phosphate adding sulfuric acid; Behind phosphoric acid to be generated and the ammonium sulfate, add by weight 0～300 part in ammonium sulfate again, heat 120～140 ℃ and obtain phosphoric acid sulphur ammonium fused matter material; With fused matter material cooling granulation, process particulate state phosphoric acid sulphur ammonium compound fertilizer material; Phosphoric acid can also melt with an ammonium nitrate or ammonium chloride Hybrid Heating altogether, generates phosphoric acid ammonium nitrate or phosphoric acid oronain, after cooling, granulation, obtains phosphoric acid ammonium nitrate or phosphoric acid oronain granular composite fertilizer again.
In the implementation that the present invention adopted, described monoammonium phosphate is counted 100 parts by weight, and concentration 98% sulfuric acid is counted 35 parts by weight.
In the implementation that the present invention adopted, described diammonium phosphate is counted 100 parts by weight, and concentration 98% sulfuric acid is counted 70 parts by weight.
The present invention is the mixture of phosphoric acid and ammonium sulfate or phosphoric acid and ammonium chloride or phosphoric acid and an ammonium nitrate, rather than compound.A kind of granulated fertilizer that to be phosphoric acid formed by ammonium sulfate or ammonium chloride or ammonium nitrate crystal parcel can natural separation be phosphoric acid and ammonium sulfate or phosphoric acid and ammonium chloride or phosphoric acid and an ammonium nitrate after being manured into soil.Invalid phosphorus, potassium that phosphoric acid is used for decomposing soil are the needed available phosphorus of plant-growth, potassium and trace element, and ammonium sulfate or ammonium chloride or an ammonium nitrate are nitrogenous fertilizer.Chemical reaction after phosphoric acid sulphur ammonium is manured into soil mainly is:
