[Detailed description of the invention] Industrial applications The present invention relates to artificial trees for ornamental greening.

Conventional technology and its problems In recent years, with the rapid development of cities, basic needs in terms of comfort and convenience have been satisfied, but on the other hand, the destruction of nature is becoming more and more serious, and urban Consumers' desires are only increasing. Local governments are trying to solve this problem by installing trees in parks and on streets, but trees often die due to incompatibility with the soil, take a long time to grow, and require maintenance such as fertilization. However, there are various problems such as the above, and currently it is not possible to meet these demands.

The present invention has been made with the aim of eliminating such conventional problems.

Means for Solving the Problems The present invention is characterized in that a natural tree part consisting of natural branches, etc. rooted by seedlings or cuttings of a natural tree is grown in an artificial trunk equipped with a hydroponic cultivation device. Related to artificial trees.

Examples Examples of the present invention will be described below with reference to the accompanying drawings.

Figures 1 and 2 show an example of the present invention in which the artificial trunk (1) is provided with an air-impermeable and water-impermeable bark part (1a). In this example, the bark part (1) of the artificial trunk (1)
a) is preferably formed into a cylindrical shape from a water-blocking synthetic resin molding material, such as vinyl chloride resin, and has cylindrical branch roots (1b) projecting outward on its outer circumferential surface in multiple vertical stages. is formed in a planar staggered manner. Branch root (1b)
It is sufficient that there is at least one in each stage, and the number of formed is not particularly limited. The upper end of the bark part (1a) may be open or closed, and the lower end is usually open. Bark part (1
A) is preferably gently tapered to give a natural tree-like appearance.

As shown in detail in the enlarged sectional view of Fig. 2, saucers (ICs) are arranged in multiple stages up and down at positions corresponding to nodes in the bark (1a), and these saucers (ICs) are located in the bark (1a). (1a
), and is integrally formed on the core tube (1d) which is loosely inserted and fixed concentrically into the core tube (1d), and maintains the arrangement position. There is a narrow gap (
1e) is formed.

As shown in FIG. 1, the bark portion (1a) is filled with porous, water-retaining inorganic granules such as perlite to form an artificial soil portion (1f). The lower end of the artificial soil portion (1f) is received by a lowermost tray (IC) and a liquid receiver (IC+) below it.

When the nutrient solution is supplied to the upper part of the artificial soil part (1f) of each node through the air hole (3f) at the upper part of each node...
...Artificial soil area (1f) while taking in more fresh air
The natural tree part of vegetation (2
) provide the roots with the nutrients and fresh air they need for growth.

The nutrient solution that remains unabsorbed in the roots of the natural tree part (2) accumulates in the saucer (1c) at the lower end of each node, and is further poured into the saucer (1c).
The liquid overflows and sequentially flows down to the lower stages, and finally is overflowed and discharged to the outside through a liquid receiver (lc') installed below the lowest stage saucer (1c). Further, the nutrient solution accumulated in the liquid receiver (lc') may be used by adjusting the pH, etc., replenishing insufficient fertilizer components, etc., and returning it to the nutrient solution tank (3a).

Therefore, the artificial soil part (1f) in the artificial main body (1) is always kept in a moist state suitable for the growth of the natural tree part (2), and the natural tree part (2) will not wither and die. Maintained in favorable growth conditions.

In the present invention, various bactericides and insecticides (including trace amounts of ozonated water, hydrogen peroxide, and other aqueous solutions) are mixed into the nutrient solution, or a piping system separate from the nutrient solution is used. Alternatively, the artificial soil may be supplied into the artificial soil section (1f).

As a means of vegetating the natural tree part (2) for the artificial trunk (1), natural waves such as rooting by cuttings are used;
A method of inserting the natural wave into the artificial soil part (1f) from the branch root part (1b) to cause rooting and growth, or using a seedling of an artificially cultivated tree, the rooting part of this young seedling is placed in the branch root part (1f) together with a nursery bed.
Through b), a method such as burying and rooting in the artificial soil part (1f) can be adopted.

Figures 3 to 8 show an example of the present invention in which the bark portion of the artificial trunk (1) maintains air permeability and water permeability.

In this embodiment, the artificial trunk (1) includes a main trunk (IA) and a plurality of branch trunks (IB) extending from the main trunk (IA), as shown in the overall view of FIG. Each branch trunk (IB) is covered with natural tree parts (2). The artificial trunk (1) is equipped with a hydroponic cultivation device (3) as in the previous embodiment.
