【発明の詳細な説明】
〔産業上の利用分野〕
本発明は低温になっても結晶析出のない液体肥料に関す
る。更に詳しくは、低温になっても結晶析出がなく、し
かも粘度安定性に優れた液体肥料に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a liquid fertilizer that does not cause crystal precipitation even at low temperatures. More specifically, the present invention relates to a liquid fertilizer that does not cause crystal precipitation even at low temperatures and has excellent viscosity stability.
液体肥料は、その使用方法−が簡便であり、農業の省力
化に伴い、広く使用されるようになって来た。Liquid fertilizers are easy to use and have come to be widely used as agriculture saves labor.
しかし液体肥料は、保存中に結晶又は不溶物が生成する
ので噴霧して使用する場合、ノズルに詰まり問題が生じ
る。特に温度が低くなると溶解度が低下するため、結晶
が析出しやすくなる。However, since liquid fertilizers generate crystals or insoluble substances during storage, when they are used by spraying, the nozzle may become clogged. In particular, when the temperature is lowered, the solubility decreases, making it easier for crystals to precipitate.
そこで、低温でも結晶を生じない液体肥料の開発が望ま
れている。Therefore, it is desired to develop a liquid fertilizer that does not form crystals even at low temperatures.
特開昭５５−１５９０１号公報はクエン酸を含有させる
ことによる液体肥料の安定性向上方法であるが特に尿素
を含む液体肥料の場合、温度上昇に伴って、尿素の加水
分解が生し、ＰＨ上昇によって不溶性物を生成するもの
で、本発明の如く、低温における結晶析出とは原因を異
にする。JP-A-55-15901 discloses a method for improving the stability of liquid fertilizer by incorporating citric acid, but especially in the case of liquid fertilizer containing urea, hydrolysis of urea occurs as the temperature rises, and the pH increases. The rise in temperature produces insoluble matter, and the cause is different from crystal precipitation at low temperatures as in the present invention.
一方、特開昭５０−１４８１６７号公報には肥料の固結
防止剤としてキチンまたはキトサンを添加した肥料が開
示されている。これは尿素、硫安、塩化カリなどの粉状
肥料の固結を防止する目的のものであり、液体肥料の結
晶析出とは全く機能を異にする。On the other hand, JP-A-50-148167 discloses a fertilizer to which chitin or chitosan is added as an anti-caking agent. The purpose of this is to prevent caking of powdered fertilizers such as urea, ammonium sulfate, and potassium chloride, and its function is completely different from the crystallization of liquid fertilizers.
本発明の目的は、肥料成分を含有する液体肥料の保存中
又は低温時に結晶の析出がなく、しかも粘度変化の少い
液体肥料を提供することである。An object of the present invention is to provide a liquid fertilizer containing fertilizer components that is free from precipitation of crystals during storage or at low temperatures and exhibits little change in viscosity.
本発明者らは、保存中、低温でも結晶を生じない液体肥

トサン及びポリアクリルアミドを添加することにより結
晶の析出を抑制し、粘度変化を少なくできることを見い
だし、本発明を完成した。As a result of intensive research to develop a liquid fertilizer that does not form crystals even at low temperatures during storage, the inventors of the present invention have found that by adding chitosan and polyacrylamide to liquid fertilizer, they can suppress the precipitation of crystals and reduce viscosity changes. The present invention was completed based on the discovery that the amount can be reduced.
すなわち、本発明は肥料成分に、キトサンおよびポリア
クリルアミドを併せて添加してなる液体肥料である。That is, the present invention is a liquid fertilizer made by adding chitosan and polyacrylamide to fertilizer components.
キトサンは、節足動物、環形動物、軟体動物などの有機
骨核物質、特に通常カニあるいはエビの甲殻を原料とし
て製造するキチンを脱アセチル化して得られるもので、
白色無定形粉末で、グルコサミン（２−アミノ−Ｄ−グ
ルコース）からなる塩基性多糖類である。遊離のものは
水に溶けないが、酸の存在で塩をつくって溶けるので、
本発明では酸に溶解して、水溶液として用いる。Chitosan is obtained by deacetylating chitin, which is usually produced from organic bone nuclei of arthropods, annelids, and molluscs, especially the shells of crabs and shrimps.
It is a white amorphous powder and is a basic polysaccharide consisting of glucosamine (2-amino-D-glucose). Free substances do not dissolve in water, but in the presence of acids they form salts and dissolve.
In the present invention, it is dissolved in an acid and used as an aqueous solution.
ポリアクリルアミドは両性表面活性剤の−って、アクリ
ルアミドからビニル基の重合によって得られる線状重合
体である。水に可溶である。Polyacrylamide, an amphoteric surfactant, is a linear polymer obtained from acrylamide by polymerization of vinyl groups. Soluble in water.
キトサン、ポリアクリルアミドは共に高分子化合物であ
るため、これらを含む液体肥料は粘性のある液体となる
。Since chitosan and polyacrylamide are both polymeric compounds, liquid fertilizer containing them becomes a viscous liquid.
キトサンを液体肥料に単独で添加すると、りん酸塩の存
在のために不溶化したり、ゲル化したりする。又ポリア
クリルアミドを単独で添加すると、低温での結晶析出、
著しい粘度低下という現象が生じる。When chitosan is added alone to liquid fertilizers, it becomes insolubilized or gels due to the presence of phosphates. Also, when polyacrylamide is added alone, crystal precipitation at low temperatures,
A phenomenon of significant viscosity reduction occurs.
しかし、本発明の液体肥料は、キトサンとポリアクリル
アミドを併用したことにより、キトサンの不溶化を防止
し、液体肥料の粘度安定性をも向上させることができる
。However, in the liquid fertilizer of the present invention, by using chitosan and polyacrylamide in combination, insolubilization of chitosan can be prevented and the viscosity stability of the liquid fertilizer can also be improved.
添加量はキトサンが０．０５〜０．３重量％、ポリアク
リルアミドが０．５〜３重量％の範囲で使用することが
好ましい。The amount of chitosan added is preferably 0.05 to 0.3% by weight, and the amount of polyacrylamide added is preferably 0.5 to 3% by weight.
キトサンが０．３重量％超であると、キトサン自体の沈
殿が生してくる。０．０５重量％未満であると、キトサ
ンの添加効果がなく、低温での結晶析出、著しい粘度低
下を生じる。ポリアクリルアミドが３重量％超であると
、分子量によっても多少異なるが、高粘性にムるため製
造が困難である。ポリアクリルアミドが０．５重量％未
満であると、ポリアクリルアミドの効果がなく、キード
サンを単独で添加した場合のようにりん酸塩の存在のた
めに不溶化したり、ゲル化したりする。When the amount of chitosan exceeds 0.3% by weight, precipitation of chitosan itself occurs. If the amount is less than 0.05% by weight, there will be no effect of adding chitosan, resulting in crystal precipitation at low temperatures and a significant decrease in viscosity. If the content of polyacrylamide exceeds 3% by weight, it becomes highly viscous and difficult to manufacture, although it varies somewhat depending on the molecular weight. If the polyacrylamide content is less than 0.5% by weight, the polyacrylamide has no effect, and the presence of phosphate causes insolubilization or gelation, as in the case where Keedsan is added alone.
製造方法としては、ポリアクリルアミドの水溶液に、窒
素、りん、カリウム等の肥料成分を投入後、溶解し、最
後にキトサン溶液を添加する。The manufacturing method involves adding fertilizer components such as nitrogen, phosphorus, and potassium to an aqueous solution of polyacrylamide, then dissolving them, and finally adding a chitosan solution.
添加する順序は限定しないが、上記の添加順序を変える
と、途中ゲル化又は不溶化といった現象が生じる場合が
あるので、上記の添加順序が好ましい。The order of addition is not limited, but if the order of addition is changed, gelation or insolubilization may occur during the process, so the above order of addition is preferable.
以下に実施例により、本発明を更に具体的に説明するが
