Electrolysis method of adjusting the pH of water to provide to cut flowers hydrangea

摘要

In the method of adjusting the pH of water provided to cut flower hydrangea of the present invention, a trace amount of sodium chloride (NaCl concentration 0.2 [mass%] or less) is added to tap water, and the cut flower part of the hydrangea is immersed in the positive (+) electrode part of the electrolysis. In the state, The step of adjusting the pH through electrolysis may include turning on power; determining whether the pH is greater than 2.2 ~ less than 3.0; Step of determining whether 5 minutes have elapsed; Power off phase; Power polarity (-) (+) switching step; Power ON phase; Determine whether pH 3.0 or higher ~ pH 5.2 or lower; power OFF phase; a step above pH 5.2; The power polarity re (+) (-) switching step; Returning to the power ON step; In any of the above steps, it includes the step of turning off the power when the vase is water exchanged or the flower arrangement is finished. According to the present invention, it is possible to provide optimal water according to the color of cut flower hydrangea, to remove chlorine contained in tap water provided to cut flower hydrangea, and to sterilize water and vases provided to cut flower hydrangea. There is.
