Abstract

This invention relates to agriculture. The purpose of the invention is to reduce the possibility of injury to the bark and damage to the bole wood. Pristvolny protective screen contains a polymer coating in the form of a disk 1 with a central hole 2 and concentric grooves 3. A discontinuous incision is made along the diameter of the central part. In the disk 1, holes are made in which the hollow rods 5 are placed. The disk is placed on a barrel circle. As the plant grows, the opening 2 gradually expands due to the successive destruction of its rings between the grooves 3 under the pressure of a thickening stem. 1 hp f-ly, 2 ill.

This invention relates to agriculture.

The purpose of the invention is to reduce the possibility of injury to the bark and damage to the bole wood.

Figure 1 shows the proposed screen, a cross-section; Fig. 2 shows the central part of the screen, axonometrics.

The screen contains a polymeric coating in the form of a disk 1 with a central hole 2 for a wooden trunk. In disc 1, grooves 3 are arranged concentrically alternately on the upper and lower surfaces. A discontinuous incision 4 is made along the diameter of the central part 4. There are also two diametrically arranged holes 1 in the disc 1, with hollow rods 5 placed. The gap between the disk 1 and the stem of the tree is sealed using elastic cut along the tube 6.

The screen is used as follows.

A disk 1 with a diameter of 0.8 m and a thickness of 0.5 cm with a hole 2 equal to twice the thickness of the stem at the root collar of a two-year-old first-class seedling of hazelnuts is placed on the stem near the stem through the stem of the planted and cut plant. The gap between the stem of the tree and the disk 1 is sealed with an elastic tube 6 with a diameter of 1 cm and a length of 8 cm, cut along. Orient the disk 1 with two holes into which hollow rods 5 are inserted, fixing it in the soil. To do this, through these holes within the planting we use scrap to make recesses in which the rods 5 with a height of 0.4 m, a wall thickness of 0.5 cm and with a diameter that rises above the soil equal to the size of the holes

ke 1. The rods 5 keep the disc 1 from possible displacements, and their cavities serve as channels for feeding mineral fertilizer solutions into the plant root zone. Disk 1 and rods 5, made of UV-resistant polyethylene, have been exploited on the hazelnut plantation for many years during the production cycle of its cultivation, excluding the development of root shoots, reducing the energy costs of deep application of mineral fertilizers, as well as loss of nutrients. As the hazelnut plant grows over the years, the central hole 2 of the stem screen gradually expands due to the successive destruction of its concentric rings between the grooves 3 under the pressure of a thickening bole, excluding trauma to its bark and thinning.

Claims (2)

1. A near-ground protective screen containing a polymer coating with a central hole for the trunk of a tree and a notch, characterized in that, in order to reduce the possibility of injury to the bark and damage to the trunk wood, the polymer coating is made in the form of a disk with concentrically located in its central part alternately on the top and the lower surfaces of the grooves, and the incision is made intermittent along the diameter of the central part. 2. The screen according to claim 1, characterized in that there are two diametrically arranged holes in the disk, in which hollow rods are placed for fastening. FIG. 2
