Abstract

FIELD: forestry. The purpose of the invention is to reduce the time of renewal of the forest. The tree to be restored is cut at a height of 55-60 cm. Industrial wood is removed from the sawed tree, and the remaining crown is grafted onto the stump. In order to eliminate the difference in the diameters of the crown and mon bore diameters, the latter are used to make wedge-shaped cuts in mutually perpendicular planes and the stump is tightened with staples until the surfaces of the wedge-shaped sections are touching. On horizontal sections, copulation sections are prepared in the form of alternating wedge-shaped projections and depressions with a decrease in height from the periphery to the center. The copulation cuts are aligned, the junction is protected with two halves of a cylindrical yoke, and to ensure the strength of the connection, the graft and the stock are connected with studs attached to the brackets. 2 hp f-ly, .4 Il.

Description

The invention relates to forestry and can be used for forest regeneration.

The purpose of the invention is to reduce the time of renewal of the forest ...

Fig, 1 shows laziness with wedge-shaped cuts; 2 shows a stump, stapled up to a diameter of a lead; FIG. 3 shows the vaccination components with copulation sections made; figure 4 - the trunk of a restored tree with fasteners-. them elements.

The method is carried out as follows.

Tree to be restored. cut at a height of 55-60 cm perpendicular to its axis. Industrial wood is removed from the tree, leaving the crown with a part of the trunk. so that the diameter of the barrel in the spot drank was at least 1/2 of the diameter of a mon. Then the cut top is grafted onto the stump.

To eliminate the difference in dia mon and grafted crown on stump 1, wedge-shaped cuts 2 are made in diametre in mutually perpendicular planes to a depth of 40-50 cm. Using two brackets 3, for example, from strip iron, at a height of 25-30 cm from the cut surface, the stump is pulled out until the surfaces of the wedge-shaped sections touch.

After obtaining the same diameters. Pn 1 and crown 4 prepare copulation sections 5 by making alternating wedge-shaped projections and depressions along the entire surface of the trunk with a decrease in height from the periphery to the center. The heights of the protrusions and valleys on the periphery correspond to 8-10 cm. The prepared copulation surfaces combine and, at the junction, impose two halves of the cylindrical collar b and bolt them together. To ensure the strength of the connection on the crown trunk, auxiliary 3 pp similar to clips are strengthened.

Claims (3)

Claim 1. A method of growing and enyaing forest crops, including planting plants, harvesting forest with leaving stumps, forming tree crowns on the stumps and growing them to obtain additional commercial wood. This is because, in order to reduce the time of 20 forest regeneration , when logging trees are cut down at a height of 55-60 cm from the soil level, the top is removed from the sawn tree so that the trunk diameter at the place of cutting is at least 1/2 of the stump diameter, and the crowns of trees are formed on stumps by grafting the top to the stump. 2. The method according to claim 1, with the fact that in order to eliminate the difference in the diameters of the grafted components on the stump, wedge-shaped cuts are made in mutually perpendicular planes to a depth of 40-50 cm and the stump is pulled to diameter at 15 howl. 3. The method according to claim 1, characterized in that the rootstock and scion perform copulation sections in the form of alternating wedge-shaped protrusions and depressions by reducing the height from the periphery to the center.
