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 seed storage section configured to store a seed of a plant and have a space for the plant to germinate, a stem storage section configured to store a stem of the plant that has germinated and elongated, and a stem holder configured to hold the elongated stem of the plant. At least a portion of the seed storage section of at least one seedling nursery unit is configured to be openable to the outside of at least one seedling nursery unit. At least a portion of the stem storage section of at least one seedling nursery unit is configured to be openable to the outside of at least one seedling nursery unit.

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 seed storage section configured to store seeds of a plant and have a space for the plant to germinate, a stem storage section configured to store a stem of the plant that has germinated and elongated, and a stem holder configured to hold the stem of the elongated plant,
at least a portion of the seed 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 seed storage section and an outside of the at least one seedling nursery unit in a direction different from a growth direction where the plant grows,
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 the outside of the at least one seedling nursery unit in the different direction, and
a width of the seed storage section in a direction perpendicular to the growth direction where the plant grows is larger than a width of the stem storage section in a direction perpendicular to the growth direction where the plant grows,
the seed storage section includes a root storage section that stores a root of the elongated plant and is open both in the growth direction where the plant grows and 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 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 elongated plant.

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

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

5. 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.

6. The seedling nursery member for grafting according to claim 5 , wherein the plurality of seedling nursery units are integrally formed.

7. The seedling nursery member for grafting according to claim 5 , 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.

8. The seedling nursery member for grafting according to claim 7 , 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.

9. The seedling nursery member according to claim 1 , wherein at least a portion of the seed storage section is configured to be openable to the outside of the at least one seedling nursery unit in the different direction so that a plant growth medium is supplied to the plant.

10. The seedling nursery member according to claim 1 , wherein at least a portion of the stem storage section is configured to be openable to the outside of the at least one seedling nursery unit in the different direction so that the plant growth medium is supplied to the plant.

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

12. The seedling nursery member for grafting according to claim 1 ,
wherein the at least a portion of the seed storage section of the at least one seedling nursery unit is configured to be openable such that the seeds are introducible into the seed storage section in the different direction, and
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.

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

14. The seedling nursery member for grafting according to claim 1 ,
wherein the seed storage section is configured to store seeds of a plant before germination.

15. The seedling nursery member for grafting according to claim 1 ,
wherein the seed storage section opens downward, and
wherein the stem storage section opens upward.

16. The seedling nursery member for grafting according to claim 1 ,
wherein the at least one seedling nursery unit has a shape of a plate, a thickness direction thereof being parallel to the different direction.

17. 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.

18. The seedling nursery member for grafting according to claim 1 ,
wherein the seed storage section has a circular cylindrical shape, a central axis thereof being parallel to the different direction, one end of the seed storage section being closed and the other end thereof being open.

19. 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 seed storage section configured to store seeds of a plant and have a space for the plant to germinate, a stem storage section configured to store a stem of the plant that has germinated and elongated, and a stem holder configured to hold the stem of the elongated plant,
at least a portion of the seed 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 seed storage section and an outside of the at least one seedling nursery unit in a direction different from a growth direction where the plant grows, and
