【発明の属する技術分野】
本発明は高塩分海苔用処理液及び海苔処理方法に関し、より詳しくは、海苔養殖における雑藻や病害を駆除又は予防するために使用される高塩分含有の海苔用処理液、並びにこの海苔用処理液を使用した海苔処理方法に関する。
本発明の目的は、酸処理液に添加しても酸処理液のｐＨを殆ど変動させることがない高塩分処理用配合塩を含有することにより、人体および環境へ悪影響をおよぼすことなく、短時間で効率よく雑藻や病害の駆除、予防処理をすることができる海苔用処理液及び海苔処理方法を提供することにある。
【０００２】
【従来の技術】
海苔養殖においては、海苔養殖における雑藻であるアオノリ、ケイソウなどや、海苔養殖における病害である赤腐れ病、白腐れ病などを予防、駆除するために海苔用処理液が使用される。
海苔用処理液には、一般的に、グリコール酸、乳酸、酒石酸、リンゴ酸、クエン酸などの有機酸が有効成分として配合され、ｐＨが１．０〜５．０程度に調整されている。このような海苔用処理液に、海苔又は海苔が付着した養殖具を浸漬することにより、雑藻や海苔の病害の駆除又は予防が行われる。
【０００３】
海苔処理において、いわゆるもぐり船と呼ばれる海苔処理の専用船が使用されている地域が存在する。もぐり船とは海苔網の下に船を潜らせて海苔用処理液を海苔網の下に素通ししながら処理をする海苔処理用の専用船である。
もぐり船を使用した海苔処理では、海苔網が海苔用処理液に浸漬している時間は、３０〜１２０秒と極めて短く、雑藻や病害を短時間で効率よく駆除することができる海苔用処理液が求められている。
【０００４】
本出願人は、短時間で雑藻や病害の駆除、予防処理をすることを可能とした海苔の処理方法及び海苔用処理液として、海水と無機塩類と酸とを含み、比重を１．０３〜１．２０に調整し、ｐＨを０．５〜５．０に調整した海苔用処理液を提案している（特許文献１参照）。
【０００５】
【特許文献１】
特開平９−２０１１８０号公報
【０００６】
【発明が解決しようとする課題】
上記した海苔用処理液を使用して海苔処理を行うには、海水に酸処理剤と無機塩類を溶解して、ｐＨと比重を調整して高塩分の海苔用処理液を調製する。この海苔用処理液に海苔網を浸漬することにより、海苔処理を行うことができる。通常の場合、塩化ナトリウムが用いられ、その添加量は処理液に対して１〜５重量％程度であり、処理液のｐＨは塩化ナトリウムを添加しない場合に比べて約０．０３〜０．２程度低下し、処理液の比重は塩化ナトリウムを添加しない場合に比べて０．００７〜０．０３５程度上昇する。
この海苔用処理液は、例えば、赤腐れ菌を３０秒〜１２０秒以内の処理時間で８０〜１００％駆除することができ、短時間処理が求められるもぐり船処理に適した海苔用処理液である。
【０００７】
もぐり船処理では船内に設置したｐＨメーターに処理液のｐＨ値を設定する。処理中に処理液のｐＨが設定値よりも上昇すると、自動的（或いは人為的）に酸が供給されて、ｐＨが設定値に達すると酸供給が止まる仕組みになっている。
無機塩類を含有する処理液の場合、塩の溶解量によって処理液のｐＨが変動する。このために、処理液のｐＨから処理液の酸濃度を把握することが困難となり、予定した酸濃度と実際の処理液の酸濃度との間のずれが大きくなり、効きむらが生じやすくなるといった問題が存在した。
【０００８】
本発明は上記課題を解決するためになされたものであり、酸処理液に添加しても酸処理液のｐＨを殆ど変動させることがない高塩分処理用配合塩を含有することにより、人体および環境へ悪影響をおよぼすことなく、短時間で効率よく雑藻や病害の駆除、予防処理をすることができ、しかも、処理液のｐＨから容易に酸濃度を把握することができ、効きむらなどが生じにくい海苔用処理液及び海苔処理方法を提供することにある。

BACKGROUND OF THE INVENTION
The present invention relates to high salinity sea moss treatment liquid and seaweed processing method, and more particularly, seaweed treatment solution of the high salt content that is used for combating or preventing Zatsumo and diseases in sea moss farming, and this The present invention relates to a laver treatment method using a laver treatment solution.

It is another object of the present invention to provide a laver treatment solution and a laver treatment method that can efficiently remove and prevent miscellaneous algae and diseases.
[0002]
[Prior art]
In nori culture, a processing solution for nori is used to prevent and control red seaweed, white rot, etc., which are algae in seaweed aquaculture, such as aonori and diatom.
Generally, organic acids such as glycolic acid, lactic acid, tartaric acid, malic acid, and citric acid are blended as active ingredients in the laver treatment solution, and the pH is adjusted to about 1.0 to 5.0. By immersing a seaweed or a culture tool to which the seaweed is attached in such a laver treatment solution, it is possible to eliminate or prevent diseases of miscellaneous algae and seaweed.
[0003]
In laver processing, there is an area where a special ship for laver processing called so-called mooring boat is used. A mooring ship is a dedicated ship for laver treatment that processes the seaweed treatment liquid while passing it under the laver net.
In the laver treatment using a mooring ship, the time that the laver net is immersed in the laver treatment solution is extremely short, 30 to 120 seconds, and the nori treatment that can effectively remove miscellaneous algae and diseases in a short time. Liquid is sought.

[Problems to be solved by the invention]
In order to perform a laver treatment using the above-mentioned laver treatment solution, an acid treatment agent and an inorganic salt are dissolved in seawater, pH and specific gravity are adjusted, and a high salinity laver treatment solution is prepared. A seaweed treatment can be performed by immersing a seaweed net in the seaweed processing solution. In normal cases, sodium chloride is used, and the amount added is about 1 to 5% by weight with respect to the treatment liquid, and the pH of the treatment liquid is about 0.03 to 0.2 compared to the case where sodium chloride is not added. The specific gravity of the treatment liquid is increased by about 0.007 to 0.035 compared to the case where sodium chloride is not added.

[0007]
In mogboat processing, the pH value of the processing solution is set in a pH meter installed in the ship.

For this reason, it becomes difficult to grasp the acid concentration of the treatment liquid from the pH of the treatment liquid, and the deviation between the planned acid concentration and the actual acid concentration of the treatment liquid becomes large, and unevenness of the effect is likely to occur. There was a problem.

In addition, there can be provided a processing solution for laver that is less susceptible to pH fluctuations due to the amount of inorganic salts dissolved, can easily determine the acid concentration from the pH of the processing solution, and is less likely to cause uneven effects. According to the invention of claim 5 of the present invention, the acid concentration can be easily grasped from the pH of the treatment liquid, and it is easy to maintain the acid concentration constant during the laver treatment, and the effect is uneven. It is possible to provide a laver treatment method capable of treating laver without generating.
