The invention relates to forestry, in particular to the cultivation of trees with a predetermined shape of the trunk for later use as supporting structures (supporting parts) of small architectural forms.

The purpose of the inventions is to increase the unification of the decorative shape of the trunk and its strength in the construction of small architectural forms.

Fig. 1 shows seedlings planted in pairs with markings for the removal of their tops and grafted branches; Fig. 2 shows a single stem that has been grafted and has been labeled with the removal mark of its tip; fig and 3 - tree after inoculation of the branches of the formed single stem; figure 5 is a bench using a decorative stem; on fig.b - fence using a decorative stem.

Yu

The method is carried out as follows.

As a planting material, saplings of pine, spruce, larch, cedar, i.e. mostly coniferous. If larch and pine are distinguished by their rapid growth and ecological plasticity, then cedar and wood are durable. In addition, the dichotomous branching of these rocks allows for a more correct and symmetric formation of the trunk. In other conditions of growth, the use of deciduous species is possible mainly with dichotomous branching (maple, canopy, etc.). All these breeds are pruned satisfactorily and grafting operations can be carried out by known methods.

Within the sites where the installation of small architectural forms is planned, pairwise planting of seedlings of 2-5 years is carried out, depending on the breed at a distance of 0.9-1.2 and relative to the cross-section of the bench provided for by the project. In this case, the distance between the pairs of planted seedlings is determined by the length of the span of the bench, so that the bench seat, laid on the supports so formed, does not have a deflection (see, figure 1),

For the fence, seedlings are planted singly at a distance of about 3.0 m, depending on the length of the hanging links of the fence (see Fig. 6).

At 3-7 years of life, and depending on the station conditions of tree growing and wood, upon reaching: seedlings 1 (see fig. 1) about 60-80 cm in height, the top 2 of each seedling is cut off flush with verticil 3, at which height the bench seat is supposed to be installed 40–50 cm. At the same time, all branches are removed, except for branches 4, facing one towards the other in pairs of trees. Left aeti fixed by stretching 5 in a horizontal position. In order to secure against unsuccessful vaccination in the future {to repeat vaccination), it is possible to leave two branches on each plant, also directed close to their opposite position.

After the branches have reached a length that overlaps the distance between the plants (50-60 cm), they are spliced by grafting. Convinced of splicing the branches, one vertex of the branches is removed (less developed).

The works of the second stage consist in increasing the decorative-adaptive qualities of a single stem {stambose

Formations). For this purpose, a 2–3-year-old formed trunk is again cut above the lower mutaaca 6 (see fig, 2), all branches except for two branches 7 located

in a single plane, on diametrically opposite plants, the Branches 7 are spliced together in a dome-shaped position by means of grafting. The hole 8 left at the same time (see fig. 3) should

have a diameter of not less than 12-15 cm. For the period of splicing, the branches should be fixed (see fig. 3).

The works of the third stage are similar to the works of the second stage. They are spent on 2-4

year after the second stage (smfig, 4).

The fourth stage is the period of free growth of trees before the time of exploitation, i.e. laying the details of the benches (back, seat). Time is approximate, depending on the energy of growth of the tree and the species can occur in 12-15 years.

Figures 5 and 6 show some possible options for forming supports of small architectural forms (bench, pillars for fences). When forming supports for fences, there is no need to carry out the work of the first stage of splicing two trees.

The tree trunk formed by the proposed method makes it possible to use it as a support for the formation of park benches and fences. At the same time, the trunk of the derr & and has sufficient strength to fulfill that function as

which it is intended to use, (L aesthetic susceptibility. Application of the method does not preclude the cultivation of trees of these forms in special containers for transplanting them later to a permanent place.
