Description
Technical field
The present invention relates to fertilizer additive, particularly a kind of powdery multi-element fertilizer anti-compaction additive and application thereof.
Background technology
Liquid manure one fertigation technology is because being improved utilization rate of fertilizer, can mechanize, mass-producing, and the many advantages such as low cost agriculture production, this technology is all able to a large amount of uses in the agriculture developed country such as Israel, the U.S. at present.Use the main using liquid fertilizer of fertilizer or the rapidly dissolvable powdery multi-element fertilizer of liquid manure one body technique.At present liquid fertilizer transports because of mechanization production, is widely applied.But not enough or need the place of long distance transportation for ducts, flexible, the rapidly dissolvable powdery multi-element fertilizer of transport condition has larger advantage.
Powdery multi-element fertilizer refers to big or middle and micro-Powdered fertilizer such as comprising nitrogen, phosphorus, potassium, sulphur, magnesium, calcium, zinc.Powdered fertilizer does not need to carry out secondary granulation processing, and therefore powdered fertilizer is lower with respect to the tooling cost of granular compound fertilizer; And powdery multi-element fertilizer have dissolve fast, formula flexibly, be easier to realize Tree Precise Fertilization and the advantage such as fertilizer efficiency is good.From above advantage, powdery multi-element fertilizer can well be promoted in theory.But in fact really not so.Powdery multi-element fertilizer is prone to the problem that hardens, and powdered fertilizer after hardening dissolves while using, accurately all bad control such as component; And powdery multielement sale price than general composite fertilizer expensive 2 ~ 3 times in the market, therefore, on market, the promotion effect of powdered fertilizer is unsatisfactory now.
In prior art, generally apply rigid package and carry out secondary package, and in the time of storing, adopt multilayer to push away and put, to alleviate transportation, to store the problem that fertilizer hardens, but anti-compaction effect is very not desirable.In addition, there is at present enterprise to adopt the method reclaiming after timing to solve the problem that hardens into lump, or adopting weight percent to reach 2% ~ 5% stearylamine, sodium laurylsulfonate etc. adds in fertilizer as anti-hard caking agent, but the cost of these two kinds of methods is all higher, make the more general composite fertilizer of market value of powdery multi-element fertilizer high, and anti-compaction effect neither be too desirable.
In view of the foregoing, be necessary the anti-compaction method of existing powdered fertilizer to improve.
Summary of the invention
The object of the present invention is to provide a kind of powdery multi-element fertilizer anti-compaction additive, solve the problem that in prior art, powdery multi-element fertilizer easily hardens.
For achieving the above object, the present invention adopts following technical scheme:
A kind of powdery multi-element fertilizer anti-compaction additive, described additive comprises following component by weight percentage: 1 ~ 30% sodium polyacrylate, 10 ~ 90% magnesium sulfate and 1 ~ 90% anhydrous calciumsulphate.
Contriver finds by lot of experiments, and fertilizer is generally by putting up a bridge or the mode of recrystallization hardens fast, and the particle diameter of powdery multi-element fertilizer is all smaller, and the phenomenon that hardens is even more serious.And by research, contriver finds to affect several principal elements that fertilizer hardens particle diameter, urea powder crystal body or ammonium nitrate crystal content size and the temperature difference of moisture in fertilizer content, pressure, fertiliser granulates.
In above-mentioned several influence factors, changing moisture in fertilizer content and pressure is all the most effective anti-compaction method.But in actually operating, due to the existence of fertilizer system own wt, inevitably extruding mutually between fertiliser granulates, and all can press bag to stack for saving Spatial General 6 R in the transporting procedures of fertilizer, therefore must have certain pressure.That is to say, can not be from reducing to carry out anti-compaction aspect pressure in actually operating.
Therefore, the present invention carries out anti-compaction by reducing moisture in fertilizer content.In the present invention, the sodium polyacrylate adding has water sorption, reduces the moisture that exists or discharge between powdered fertilizer particle by water suction, and the formation of bridging or recrystallization between blocking-up fertiliser granulates, to reach the object that prevents that powdered fertilizer from hardening.
Sodium polyacrylate can absorb water in a large number, add the effect in granulated fertilizer with water suction and guarantor's retaining to, and sodium polyacrylate in water suction simultaneously, can improve system viscosity, therefore, in the prior art, conventional water-holding agent or the binding agent that does granulated fertilizer of sodium polyacrylate.But, in powdered fertilizer, only adding sodium polyacrylate, can increase the weight of because the water-absorbent of sodium polyacrylate makes the powdery fertilizer situation of hardening.Magnesium sulfate, anhydrous calciumsulphate also have water sorption, and can not increase because water suction makes system viscosity.But because calcium sulfate solubleness is low, powdered fertilizer is used for fertigation, therefore can not in powdery fertilizer, use in a large number calcium sulfate.
Contriver finds in experiment, sodium polyacrylate, magnesium sulfate and anhydrous calciumsulphate are added in powdered fertilizer according to a certain percentage, three's synergy can well play anti-compaction effect to powdery fertilizer, and the time that the powdery fertilizer of interpolation additive of the present invention can be stacked 2 years under the indoor storage requirement of routine does not harden.And, adding above-mentioned three kinds of materials are added in powdered fertilizer according to this ratio, powdered fertilizer is still soluble in water, does not affect the application of powdery fertilizer in fertigation.
In addition sulphur, magnesium and three kinds of moderate-elements of calcium of in additive of the present invention, containing, are also the required nutrition of plant-growth; Additive is not only easy to use, environment friendly and pollution-free, and production technique is simple, environmental protection, with low cost, is easy to promote.
