A propagation tray assembly comprising a support tray and a plurality of seedling holder inserts locatable in the support tray in side by side relationship, each insert comprising a row of cells, each cell having an open top and an open side to facilitate inspection and removal of the contents thereof when the respective insert is removed from the support tray, wherein the open sides of each cell in a first insert are closed by the adjacent insert when the inserts are located in the support tray in side by side relationship.

An aeroponics system is provided which includes a rack with multiple shelves thereon and with a tray accommodated on each shelf. Light modules are located above each shelf. Each tray has a hood with openings therein leading into a hollow chamber and above a base which includes spray heads therein. Water from a reservoir upon the rack is pumped to each of the spray heads to provide a spray within the hollow chambers. Plant cuttings are placed passing through the openings in the hood so that lower portions of the cuttings can receive the spray (and nutrients added into the reservoir) for propagation of the plant cuttings.

Provided is a plant cultivation device where installation work, repair, partial improvement or remodeling work can be performed easily. A plurality of seedling growing units 2 are connected to each other in series. The seedling growing unit 2 has a case which has both ends thereof opened and can cover a peripheral surface of the seedling growing unit 2. A tray mounting base, a conveyance device, an illumination unit, and a water supply/discharge facility are disposed inside the case. The cases of the seedling growing units 2 are connected to each other thus forming a continuous cylindrical space. A series of conveyance units are formed by the conveyance devices inside the cases. Cultivation trays are disposed in the continuous cylindrical space formed by the cases, and the cultivation trays are movable toward a downstream side by the conveyance unit in a state where the cultivation tray strides over the case.

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.

A planter assembly is provided. The planter assembly includes a grower planter and a shell planter. The grower planter includes an upper distal end. The grower planter includes an upper distal end. The shell planter is structured to enclose said grower planter. That is, when the grower planter is disposed in the shell planter, the grower planter distal end is disposed subjacent to the shell planter distal end. Further, in an exemplary arrangement, a shell planter body sidewall distal end subjacent, inner surface is sized relative to the grower planter body sidewall distal end maximum cross-sectional area to be one of a corresponding size, a closely corresponding size, or a snuggly corresponding size.

The plant cultivation device which workability of cutting of the leaves of the plant at the base portion thereof from the root portion of the plants. The plant cultivation device includes a culture medium holding portion in a cylindrical shape, accommodating and holding a seedling culture medium, arranged in the through-holes of the fluid passage member and absorbing the culture fluid into the seedling culture medium and a leaf supporting portion formed in a cylindrical shape, arranged at an upper side of the culture medium holding portion and supporting the leaves from around the leaves which are cultivated from the seeds. The culture medium holding portion and the leaf supporting portion are formed such that a cutting tool, used for separation between the seedling culture medium and the leaves, can be insertable from outside into a bordering portion between the culture medium holding portion and the leaf supporting portion.

A plant cultivation device includes a first plate portion formed in a plate shape extending in a transfer direction from the fluid passage member and a second plate portion formed in a plate shape extending in a direction opposite to the transfer direction from the fluid passage member. When the distance between the two neighboring fluid passage members becomes large, the second plate portion provided on the preceding fluid passage member and the first plate portion provided on the following fluid passage member are separated from each other with respect to the transfer direction. The plant cultivation device saves space particularly in an early raising stage of the leaves, keeping protection of the cultivated leaves not to be drooped down.

Container (1) for the transport of rooted plant cuttings (2), wherein the container comprises upright walls (3) which are made substantially of wood or rigid woody material. Grids (4) may be received between the walls, each grid being arranged to receive plant cuttings. The grids may also be made of wood or rigid woody material. The container is arranged and shaped so as to be stackable by form fit with similar containers. A loose base (5) is arranged and shaped so as to cooperate by form fit with the walls of the container.

A device and method for penetrating a hydrophobic layer caused by a fire and introducing new vegetation into a forest floor includes seeds, seedlings, and/or saplings carried within a plurality of tapered containers, possibly mixed with soil, sand, gravel, fertilizer, SAP granules, and/or water. The containers are inserted into the ground through the hydrophobic layer by dropping or propelling them from an aircraft, or manually pressing on them. One or more holes proximate the bottoms of the containers enable rain water and germinating roots to penetrate into soil beneath the hydrophobic layer. A perforated lid can prevent the seeds or seedlings from being ejected upon impact with the forest floor. A weighted tip can improve penetration of the containers into the forest floor. A plurality of tapered containers can extend downward from a tray or frame. The container and/or perforated lid can be made from biodegradable materials.

A plurality of freestanding non-porous planting blocks, each containing a plurality of tapered planting cells, are used in conjunction with a water container. Each planting cell has non-permeable sidewalls as well as open top and bottom apertures. The bottom apertures of the planting cells on the bottom surface of the corresponding planting block, will be submersed in water within the container allowing for subirrigation. The container can be an in-ground reservoir or a manufactured container of permanent or portable nature. Plant material placed in the planting cells, with or without planting media, will grow into field-ready plants for storage or harvest. The system is used for economically enhanced plant production of field-ready trees, shrubs, forbs, perennials, vegetables and grasses.
