## Abstract

A grafting method includes: making a cut surface of a scion and a cut surface of a rootstock contact with each other, and disposing sheet-like thermoplastic resin films facing each other across a contact part; and covering a periphery of the contact part with the thermoplastic resin films by ultrasonically welding the thermoplastic resin films.

## Claims

### Claim 1

A grafting method comprising:
making a cut surface of a scion and a cut surface of a rootstock contact with each other, and disposing separate sheet-like thermoplastic resin films facing each other across a contact part; and
covering a periphery of the contact part with the thermoplastic resin films by ultrasonically welding the thermoplastic resin films together, wherein
the covering includes ultrasonically welding the thermoplastic resin films while applying a predetermined tensile load in a direction intersecting with axis directions of the scion and the rootstock and a direction in which the thermoplastic resin films face each other.

### Claim 2 (depends on 1)

The grafting method according to claim 1, wherein
the disposing of the sheet-like thermoplastic resin films facing each other includes interposing the contact part between a first part and a second part that face each other when a single thermoplastic resin film is folded.

### Claim 3 (depends on 1)

The grafting method according to claim 1, wherein
the disposing of the sheet-like thermoplastic resin films facing each other includes interposing the contact part between two thermoplastic resin films facing each other.

### Claim 4 (depends on 1)

The grafting method according to claim 1, wherein
the disposing of the sheet-like thermoplastic resin films facing each other includes applying a predetermined tensile load in a direction intersecting with axis directions of the scion and the rootstock and a direction in which the thermoplastic resin films face each other, and
the covering includes ultrasonically welding the thermoplastic resin films applied with the predetermined tensile load.

### Claim 5 (depends on 1)

The grafting method according to claim 1, wherein
the thermoplastic resin films are transparent.

### Claim 6

A grafting method comprising:
making a cut surface of a scion and a cut surface of a rootstock contact with each other, and disposing separate sheet-like thermoplastic resin films facing each other across a contact part; and
covering a periphery of the contact part with the thermoplastic resin films by ultrasonically welding the thermoplastic resin films together, wherein
the covering includes ultrasonically welding the thermoplastic resin films while applying a predetermined tensile load in a direction intersecting with axis directions of the scion and the rootstock and a direction in which the thermoplastic resin films face each other, and
the thermoplastic resins films are joined together at one end in the direction the predetermined tensile load is applied.

### Claim 7 (depends on 6)

The grafting method according to claim 6, wherein
the disposing of the sheet-like thermoplastic resin films facing each other includes interposing the contact part between a first part and a second part that face each other when a single thermoplastic resin film is folded.

### Claim 8 (depends on 6)

The grafting method according to claim 6, wherein
the disposing of the sheet-like thermoplastic resin films facing each other includes interposing the contact part between two thermoplastic resin films facing each other.

### Claim 9 (depends on 6)

The grafting method according to claim 6, wherein
the disposing of the sheet-like thermoplastic resin films facing each other includes applying a predetermined tensile load in a direction intersecting with axis directions of the scion and the rootstock and a direction in which the thermoplastic resin films face each other, and
the covering includes ultrasonically welding the thermoplastic resin films applied with the predetermined tensile load.

### Claim 10 (depends on 6)

The grafting method according to claim 6, wherein
the thermoplastic resin films are transparent.
