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 all is able to a large amount of uses in agriculture developed countries 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.Liquid fertilizer transports because of mechanization production at present, 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 then has larger advantage.
The powdery multi-element fertilizer refers to comprise the big or middle and micro-Powdered fertilizer such as nitrogen, phosphorus, potassium, sulphur, magnesium, calcium, zinc.Powdered fertilizer does not need to carry out secondary granulation processing, so powdered fertilizer is lower with respect to the tooling cost of granular compound fertilizer; And the powdery multi-element fertilizer has, and dissolving is fast, prescription flexibly, be easier to realize the advantages such as Tree Precise Fertilization and fertilizer efficiency be good.From above advantage, the powdery multi-element fertilizer can access good popularization in theory.But in fact really not so.The powdery multi-element fertilizer is prone to the problem that hardens, and the powdered fertilizer after hardening is used time dissolving, accurately all bad control such as component; And powdery multielement sale price is than general composite fertilizer expensive 2 ~ 3 times in the market, and therefore, the promotion effect of powdered fertilizer is unsatisfactory on the market now.
In the prior art, generally use rigid package and carry out secondary package, and when storing, adopt multilayer to push away and put, transport to alleviate, store the problem that fertilizer hardens, but the anti-compaction effect is very desirable.In addition, the method that reclaims after having at present enterprise to adopt regularly solves the problem that hardens into lump, or adopt weight percent to reach 2% ~ 5% stearylamine, sodium laurylsulfonate etc. and add in the fertilizer as anti-hard caking agent, but the cost of these two kinds of methods is all higher, so that the more general composite fertilizer of the market value of powdery multi-element fertilizer is high, and the anti-compaction effect neither be too desirable.
In view of the foregoing, be necessary the anti-compaction method of existing powdered fertilizer is improved.
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 the powdery multi-element fertilizer easily hardens in the prior art.
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% sal epsom and 1 ~ 90% anhydrous calciumsulphate.
The contriver finds by lot of experiments, and fertilizer generally is 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, the contriver finds to affect particle diameter, urea powder crystal body or ammonium nitrate crystal content size and the temperature difference that several principal elements that fertilizer hardens have moisture in fertilizer content, pressure, fertiliser granulates.
In above-mentioned several influence factors, changing moisture in fertilizer content and pressure all is the most effective anti-compaction method.But in actually operating, and since the existence of fertilizer system own wt, inevitably mutually extruding 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 the 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 that adds has water sorption, reduces the moisture that exists or discharge between the powdered fertilizer particle by suction, and the formation of bridging or recrystallization between the blocking-up fertiliser granulates is to reach the purpose that prevents that powdered fertilizer from hardening.
Sodium polyacrylate can absorb water in a large number, adds the effect that has suction in the granulated fertilizer and protect retaining to, and sodium polyacrylate in suction simultaneously, can improve system viscosity, therefore, in the prior art, sodium polyacrylate water-holding agent or the binding agent of doing granulated fertilizer commonly used.But, in powdered fertilizer, only add sodium polyacrylate, can the powdery fertilizer situation of hardening be increased the weight of owing to the water-absorbent of sodium polyacrylate.Sal epsom, anhydrous calciumsulphate also have water sorption, and can not increase because suction makes system viscosity.But because calcium sulfate solubleness is low, powdered fertilizer is multiplex in fertigation, therefore can not use in a large number calcium sulfate in powdery fertilizer.
The contriver finds in experiment, add to according to a certain percentage sodium polyacrylate, sal epsom and anhydrous calciumsulphate in the powdered fertilizer, three's synergy can well play the 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, according to this ratio interpolation above-mentioned three kinds of materials being added in the powdered fertilizer, powdered fertilizer is still soluble in water, does not affect the application of powdery fertilizer in fertigation.
In addition, the sulphur that contains in the additive of the present invention, magnesium and three kinds of moderate-elements of calcium also are 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.
