Description

Detailed Description of the Invention [Industrial Application Fields] The present invention provides a planted foundation for planting that does not require supports and branch lines, and is particularly suitable for planting trees in urban areas, golf courses, etc. Regarding cultivation methods.

[Conventional technology] Conventionally, in order to plant a tree, a root ball with a root wrap is inserted into a root hole that has been previously excavated in the ground, and then soil is buried in the cavity of the root hole, and soil is buried in the root hole to prevent it from tipping. The method used was to support the tree by fixing a pole to the tree's trunk, or by stringing branch wires anchored into the ground around the tree.

However, such conventional methods require pillars or branch lines to prevent the building from tipping, which has the disadvantage of impairing the scenery or interfering with traffic.

Therefore, in recent years, a method of planting trees that does not require supports or branch lines has been developed as shown in FIG.

As shown in the figure, the root ball 22 with the root wrapping 21 is inserted into the root hole H excavated in the ground, placed on the root base B, and the wire 25 wound around the root ball 22 is inserted into the soil. The tree 23 is connected to an anchor 26 set inside the tree and soil 27 is buried in the root hole cavity, and supports the tree 23 when standing upright without installing supporting means such as pillars or branch lines on the ground to prevent the tree from tipping. This makes it possible to plant street trees in narrow spaces.

[Problem to be solved by the invention 1 However, in this tree planting method, trees 23
When the tree 23 becomes large in size, the root hole bottom B sinks due to the tree 23's own weight, leading to a situation where the tree 23 leans over.

Furthermore, when the tree 23 is planted by the above method, the soil 27' buried in the root hole cavity is still soft at the initial stage of planting, and when a lateral force such as a strong wind acts on the planted tree 23, the root ball 27' When the tree swings sideways, the anchor 26 is also pulled each time, creating a gap in the soil around the root ball 22, causing the inconvenience that the tree 23 gradually leans.

In addition, since the bottom of the root ball 22 is rounded, it is very unstable when placed in the root hole H, and if the work of tightening the root ball 22 to the anchor 26 with the wire 25 is not done carefully, the tree 22 There was a risk of it tipping over.

The present invention was made to solve these problems, and it is possible to deal with the rounded shape of the bottom of the root ball, to reliably support the tree root ball in the ground, and to prevent the tree root from being erected. To provide a method and device for planting a tree, which allows a pot to stand on its own without sinking (and also without leaning even when hit by strong winds).
