Abstract

A seedling nursery member for grafting according to an aspect of the present disclosure includes at least one seedling nursery unit. At least one seedling nursery unit includes a stem storage section configured to store a stem of a plant and a stem holder configured to hold the stem of the plant. At least a portion of the stem storage section of the at least one seedling nursery unit is configured to be openable so as to allow communication between an inside of the stem storage section and an outside of the at least one seedling nursery unit in a direction different from a growth direction of the plant.

First claim

The invention claimed is:

1. A seedling nursery member for grafting, comprising:
at least one seedling nursery unit,
wherein the at least one seedling nursery unit includes a stem storage section configured to store a stem of a plant, a stem holder configured to hold the stem of the plant, and a root storage section,
at least a portion of the stem storage section of the at least one seedling nursery unit is configured to be openable so as to allow communication between an inside of the stem storage section and an outside of the at least one seedling nursery unit in a direction different from a growth direction of the plant,
the root storage section is configured to store a root of the plant and is open in the different direction, and
a length of the root storage section in the growth direction where the plant grows is larger than a width of the root storage section in a direction perpendicular to the growth direction where the plant grows.

2. The seedling nursery member for grafting according to claim 1 , wherein the at least a portion of the stem storage section of the at least one seedling nursery unit is configured to be openable such that a plant growth medium is suppliable into the stem storage section in the different direction.

3. The seedling nursery member for grafting according to claim 1 , wherein the at least a portion of the stem storage section of the at least one seedling nursery unit is open so as to allow communication between the inside of the stem storage section and the outside of the at least one seedling nursery unit in the different direction.

4. The seedling nursery member for grafting according to claim 1 , wherein the stem holder of the at least one seedling nursery unit is configured to be movable so as to hold the stem of the plant in a state of being in contact with the stem of the plant.

5. The seedling nursery member for grafting according to claim 1 , wherein the at least one seedling nursery unit has a shape of a plate.

6. The seedling nursery member for grafting according to claim 5 , wherein a thickness direction of the at least one seedling nursery unit is parallel to the different direction.

7. The seedling nursery member for grafting according to claim 1 , wherein the at least one seedling nursery unit includes an elastically deformable material.

8. The seedling nursery member for grafting according to claim 1 , wherein the at least one seedling nursery unit includes a plurality of the seedling nursery units.

9. The seedling nursery member for grafting according to claim 8 , wherein the plurality of seedling nursery units are integrally formed.

10. The seedling nursery member for grafting according to claim 8 , wherein the plurality of seedling nursery units are arranged side by side in a predetermined direction such that the respective stem storage sections of the plurality of seedling nursery units are oriented in an identical direction.

11. The seedling nursery member for grafting according to claim 10 , wherein in the plurality of seedling nursery units, the respective stem storage sections of the plurality of seedling nursery units are arranged side by side at equal intervals.

12. A seedling nursery set for grafting comprising a plurality of the seedling nursery members for grafting according to claim 1 .

13. The seedling nursery member for grafting according to claim 1 , wherein the at least one seedling nursery unit has a shape of a plate including a hole through which the stem of the plant passes, the hole being formed in a direction perpendicular to a thickness direction of the plate.

14. A method for producing a grafted seedling, comprising:
preparing a first seedling nursery member and a second seedling nursery member, each of which comprises:
at least one seedling nursery unit,
wherein the at least one seedling nursery unit includes a stem storage section configured to store a stem of a plant, a stem holder configured to hold the stem of the plant, and a root storage section,
at least a portion of the stem storage section of the at least one seedling nursery unit is configured to be openable so as to allow communication between an inside of the stem storage section and an outside of the at least one seedling nursery unit in a direction different from a growth direction of the plant,
the root storage section is configured to store a root of the plant and is open in the different direction, and
a length of the root storage section in the growth direction where the plant grows is larger than a width of the root storage section in a direction perpendicular to the growth direction where the plant grows;

holding a stem of a first plant by the stem holder of the seedling nursery unit in the first seedling nursery member;
cutting the stem of the first plant held by the stem holder of the seedling nursery unit in the first seedling nursery member;
holding a stem of a second plant by the stem holder of the seedling nursery unit in the second seedling nursery member;
cutting the stem of the second plant held by the stem holder of the seedling nursery unit in the second seedling nursery member; and
joining a cut surface of the stem of the first plant held by the stem holder of the seedling nursery unit in the first seedling nursery member and a cut surface of the stem of the second plant held by the stem holder of the seedling nursery unit in the second seedling nursery member.

15. The method for producing a grafted seedling according to claim 14 further comprising:
dividing the first seedling nursery member into a plurality of portions to form a plurality of divided pieces; and
dividing the second seedling nursery member into a plurality of portions to form a plurality of divided pieces,
wherein the joining of the cut surface of the stem of the first plant held by the stem holder of the seedling nursery unit in the first seedling nursery member and the cut surface of the stem of the second plant held by the stem holder of the seedling nursery unit in the second seedling nursery member includes arranging one of the plurality of divided pieces in the first seedling nursery member and one of the plurality of divided pieces in the second seedling nursery member such that the cut surface of the stem of the first plant held by the stem holder of the seedling nursery unit in the first seedling nursery member is in contact with the cut surface of the stem of the second plant held by the stem holder of the seedling nursery unit in the second seedling nursery member.

16. The method for producing a grafted seedling according to claim 14 , wherein the at least a portion of the stem storage section of the at least one seedling nursery unit is configured to be openable such that a plant growth medium is suppliable into the stem storage section in the different direction.

17. The method for producing a grafted seedling according to claim 14 , wherein the at least a portion of the stem storage section of the at least one seedling nursery unit is open so as to allow communication between the inside of the stem storage section and the outside of the at least one seedling nursery unit in the different direction.

18. The method for producing a grafted seedling according to claim 14 , wherein the at least one seedling nursery unit has a shape of a plate, a thickness direction thereof being parallel to the different direction.

19. The method for producing a grafted seedling according to claim 14 , wherein the at least one seedling nursery unit has a shape of a plate including a hole through which the stem
