BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut flower freshness holding member capable of holding cut flower freshness for a long period of time with cut flowers arranged in a container such as a vase.

[0002]

2. Description of the Related Art In order to store plants such as cut flowers in a fresh state for a long period of time, it is desirable to remove ethylene gas generated from the plants. Therefore, by adsorbing ethylene gas, the freshness of cut flowers is kept. The technique has been developed as described in, for example, Japanese Patent Laid-Open No. 1-86830.

As a result of recent research, it has been found that when cut flowers are supplemented with nutrients such as sugar, generation of metamorphic gas such as ethylene gas is suppressed and the freshness of cut flowers can be extended. However, when sugar is supplied to the water in the vase, bacteria such as bacteria multiply in the water, which causes the bacteria to block the conduit of the cut flower stem, resulting in the cut flowers wilting. Will be lost.

[0004]

Therefore, in order to maintain the freshness of cut flowers for a relatively long period of time, it is necessary to frequently exchange water or to add a fungicide that suppresses the growth of bacteria into the water. Although desirable, handling bactericides at home is not preferred and the optimum amount is not well understood by the average consumer.

Therefore, a sheet material containing a sterilizing agent and specifying the method of use has been developed. However, if such sheet material is put in a transparent vase, the vase is Since the sheet material is visually observed through the outside, the sheet material is annoying to the customer who appreciates the flowers, and it is necessary to remove the sheet material from the vase after a predetermined time has elapsed.

An object of the present invention is to prevent wilting of cut flowers in a short period of time without observing the use thereof from the outside and eliminating the need for a sheet material removing operation.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.
