本発明はハロゲン化銀を主成分とする切り花月延命剤に
関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a cut flower life-extending agent containing silver halide as a main component.

農業生物化学研究所のフエーンが発表して以来、その効
果が各国で追試確認されて急速に普及し、我国において
も、この水溶液が切り花月延命剤として盛んに使用され
るようになった。(Prior Art) Petals are usually separated from the roots, ie, appreciated as cut flowers, and sold or otherwise handled. Therefore, conventionally, nutrients such as sugars are added to the water in which cut flowers can be kept to activate them, 8-hydroxyquinoline sulfate is added to suppress the growth of pathogenic bacteria, and silver ions are added. Measures have been taken to extend the life of cut flowers by suppressing ethylene biosynthesis, which accelerates the aging and ripening of cut flowers. In particular, since 1978, when Fehn of the Netherlands Institute of Agricultural and Biological Chemistry announced the effect of an aqueous solution of silver thiosulfate complex salt on extending the life of cut flowers, the effect has been confirmed in follow-up tests in various countries, and it has rapidly become popular. This aqueous solution is now widely used as a life-extending agent for cut flowers.
（発明が解決しようとする問題点）
ところで、チオスルファト銀錯塩水溶液は単独では不安
定で放置しておくと硫化銀の黒色沈澱を生じて切り花の
延命効果が減滅するため一旦調整した水溶液は直ちに使
い切ることが必要であって、一定時間を経過したものは
廃棄せざるを得ないのである。(Problems to be Solved by the Invention) By the way, an aqueous solution of silver thiosulfate complex salt is unstable when left alone, and if left alone, a black precipitate of silver sulfide will be formed, reducing the life-extending effect of cut flowers, so once an aqueous solution is prepared, it should be used up immediately. This is necessary, and items that have been used for a certain period of time must be discarded.
この様なことから従来は、銀塩とチオ硫酸塩及び亜硫酸
塩、亜硫酸水素塩等の安定剤を夫々水に溶解させておき
、然してこれらを撹拌しながら混合して延命液を調整し
、更に使用目的に応じてこれを適宜稀釈する方法が採ら
れている（特開昭６１−２０７３０１号）。For this reason, in the past, silver salts and stabilizers such as thiosulfates, sulfites, and bisulfites were dissolved in water, and then these were mixed with stirring to prepare a life-extending solution. A method has been adopted in which it is diluted as appropriate depending on the purpose of use (Japanese Patent Application Laid-open No. 207301/1983).
しかしながらこの様にして調整された延命液はなお可成
り安定性が低いため、これを保存しようとすると液の濃
度を硝酸銀の含有量が０．５％以下になるように薄くし
なければならないのである。 そのため従来の延命液は
稀釈率がせいぜい１０〜１００倍程度と極めて低いので
、必然的に取扱い量が多くなり、取扱いコストや製造コ
ストが嵩むのである。However, the stability of the life-extending solution prepared in this way is still quite low, so in order to preserve it, the concentration of the solution must be diluted so that the silver nitrate content is 0.5% or less. be. Therefore, since the dilution rate of conventional life-extending fluids is extremely low, at most 10 to 100 times, the amount to be handled is inevitably large, leading to increased handling and manufacturing costs.
しかもこの延命液は液中に塩素イオンが含まれていると
銀イオンがこれと結合して塩化銀となって析出すること
と、延命液が薄いため僅かの銀の析出が延命効果の低下
に影響することから、各材料を溶解する水も水道水の様
な塩素イオンを含有する水を使用することができないの
で、その点でも製造コストの高いものとなるのである。Moreover, if this life-extending solution contains chlorine ions, silver ions will combine with them and precipitate as silver chloride, and since the life-extending solution is thin, a small amount of silver precipitation will reduce the life-extending effect. Because of this, water containing chlorine ions, such as tap water, cannot be used for dissolving each material, which also increases production costs.
この様なことから従来から、安定性の高い。Because of this, it has traditionally been highly stable.
高濃度の切り徳用延命剤の開発が望まれたのである。There was a desire to develop a highly concentrated life-extending agent for cutting.
（問題点を解決するための手段）
本発明者等は上記した従来の切り徳用延命剤について研
究した。 その結果、上記した切り徳用延命剤の不安定
性は、夫々の材料を水に溶解して水溶液とし、然るのち
これらを混合する点と、銀塩として硝酸銀、酢酸銀を使
用する点にあり、且つ液中に塩素イオンが存在しないこ
とを要件としている点にあることを見出し、同時に水に
対する溶解度の低い塩化銀がチオ硫酸ナトリウム水溶液
に溶解し。(Means for Solving the Problems) The present inventors conducted research on the above-mentioned conventional life-extending agent for cutting. As a result, the instability of the above-mentioned life-extending agents for cuttings is due to the fact that each material is dissolved in water to form an aqueous solution, and then these are mixed together, and that silver nitrate and silver acetate are used as silver salts. In addition, they discovered that silver chloride, which has low solubility in water, is dissolved in an aqueous sodium thiosulfate solution.

である。Moreover, they discovered that this aqueous solution was highly stable, and based on this knowledge, first dissolved sodium thiosulfate in water, added and dissolved a stabilizer and silver halide to this aqueous solution, and then dissolved this aqueous solution. It is used as a life-extending agent.
（発明の構成）
本発明の切り徳用延命剤はハロゲン化銀１〜５部とチオ
硫酸ナトリウム１０〜５０部。(Structure of the Invention) The life-extending agent for cuttings of the present invention contains 1 to 5 parts of silver halide and 10 to 50 parts of sodium thiosulfate.

を弱酸性に調整する前に加えるのが好ましい。Next, a method for preparing the life-extending agent for cuttings of the present invention will be described. First of all,
Add and dissolve 10 to 50 parts of sodium thiosulfate in 100 parts of water. In this case, the water may be water containing chlorine ions, such as tap water. Next, 1 to 20 parts of a stabilizer and 1 to 5 parts of silver halide are added and dissolved in this aqueous solution to obtain a life-extending agent for product cutting.
There is no particular restriction on the order in which silver halide and stabilizers are added to the aqueous sodium thiosulfate solution, but the antioxidant should be added before adding an inorganic acid, an organic acid, or a salt thereof to the aqueous solution to make it weakly acidic. It is preferable to add
（実施例） 以下、本発明の一実施例を示す。(Example) An embodiment of the present invention will be shown below.

They were mixed to prepare a life-extending solution (however, the concentration of silver ions in this life-extending solution was the same as that of the example and 10 times that of the conventional solution). In order to compare the stability of the life-extending solutions of the above examples and comparative examples, both solutions were tested at 30%
It was kept at a temperature of ℃. As a result, there was almost no change in the life-prolonging liquid of the example even after 100 days.
これに対して比較例の試料は１０日間を経 。On the other hand, the comparative sample was used for 10 days.
過した時点で黒色の沈澱を生じた。A black precipitate was formed.

が低減される。Therefore, in producing this, the water used does not need to be water from which chlorine has been removed, such as distilled water, and therefore no distillation or desalination equipment is required. In addition, since the concentration is high, the dissolution tank can be made smaller, and since silver chloride and other substances are directly dissolved in the sodium thiosulfate aqueous solution, the number of dissolution tanks can be reduced.As a result, the equipment can be significantly simplified. This results in a reduction in production time and work plates. Further, after manufacturing, handling such as advancing and transporting becomes easier, and the cost thereof is reduced.
