Description

The utility model relates to agriculture, in particular to horticulture, and is intended for use in grafting technology by copulation of fruit, ornamental trees and shrubs.

The technical problem to be solved by the utility model is to simplify the grafting technology by copulation of fruit, ornamental trees and shrubs, to increase the survival rate of grafts by fixing, protecting the grafting site and stimulating the fusion of rootstock and scion.

A known method of grafting by copulation, according to which a scion with a stock of the same diameter is used. After grafting, the junction of the scion with the stock is tied with a PVC or polyethylene film 8-12 mm wide (Solonets G.K., Kovalenko G.K. Grafting of fruit trees. - Minsk: Urajay, 1987. - 48 p.). As a strapping material, it is known to use various types of synthetic films, in particular films, one of the sides of which can be covered with an adhesive layer (Application for invention RU 2012121664 A, 05/28/2012), as well as a photodegradable film (Patent for invention RU 2302102 C2, 05.08 .2005). The disadvantage of using films as a strapping material is the high complexity of strapping, insufficient mechanical fixation and protection against infection of the junction.

It is known to use a black heat-shrink sleeve with a thickness of 60 microns, a length of 400 mm, a diameter of 7 ÷ 12 mm, which is put on the junction of the stock with the scion and seated with a stream of heated air at a temperature of 300 ° C for 4 ÷ 5 s (Patent for the invention RU 2699528 C1, 08/15/2018). The disadvantage of using a heat shrink sleeve is the need for high temperature shrinkage, which can lead to difficulty in using the invention in the field, to burns and necrosis of the cambium at the grafting site due to exposure to high temperatures.

In horticulture, physiologically active substances are widely used as plant growth stimulants, including during grafting. There is a known method of using a polyethylene cover, which is put on the junction of the stock with the scion, filled with a 0.003-0.005% solution of indoleacetic acid and thermal shrinkage of the cover on the graft is carried out (Author's certificate SU1391537A1, 05.03.1986). It is also known to use fungicides as part of means for protecting plant wounds and grafts (Application for invention RU 2010115966 A, 23.09.2008; patent for invention RU 2245620 C1, 11.06.2003),

The closest analogue of the utility model is a medical bactericidal adhesive plaster for closing wounds, consisting of an adhesive carrier tape made of a thin web or a polymer film with a one-sided adhesive coating and a layer of material fixed on it that promotes wound healing - bactericidal gauze. The sticky coating on the patches is protected from contact with the environment using a protective film that is removed immediately before use (Burenin P.I. Adhesive plaster // Big Medical Encyclopedia. Editor-in-Chief Academician B.V. Petrovsky. - M: Soviet Encyclopedia, 1980. V. 12. - S. 477; OFS.1.4.1.0009.15 Medical plasters. URL .: https://pharmacopoeia.ru/ofs-1-4-1-0009-15-plastyri-meditsinskie/ (date appeals: 05/14/2021)). A bactericidal adhesive plaster is known, consisting of an adhesive tape, on the surface of which, on the sticky side, a hygroscopic atraumatic material impregnated with a solution of antiseptic substances and dried is fixed (Patent for invention RU 2149617 C1, 20.09.1999). However, the medical patch has a fundamentally different scope. The ingress of plastic masses of the sticky layer and bactericidal agents of the patch to the junction of the scion with the rootstock, on the plant tissue can lead to the death of the cambium, to a slowdown or absence of fusion of the scion with the rootstock.

To solve the technical problem, it was taken into account that, as a rule, cuttings are used for grafting, the diameter of which can vary from 0.5 to 2 cm (the optimal diameter of the cuttings is 0.7-1.5 cm), which corresponds to a circumference from 1.57 to 6.28 cm (the optimal circumference of the cuttings is 2.2-4.7 cm), and the junction of the scion with the rootstock, which is optimally about 3-3.5 of the cutting diameter (with a cutting diameter of 1.5 cm, the junction will be about 5 cm) must be protected from infection and foreign matter, and the junction must be securely fixed with several layers of strapping material to ensure the fusion of the scion with the rootstock.

The patch for bandaging vaccinations is illustrated by the drawing: in Fig. 1 shows a general view of the patch, top view.

The patch for bandaging grafts by the method of copulation of fruit, ornamental trees and shrubs consists of three layers. The first layer is a common waterproof substrate measuring 8×22 cm (in the drawing, not shown in general view). The substrate consists of two parts 15 and 7 cm long. On the greater part of the substrate 15 cm long (1) an adhesive layer (2) is applied, covered with a protective removable film (3). On a short part of the substrate (4) 7 cm long, along its upper and lower edges in the form of strips 1.5 cm wide each (5), a layer of garden pitch 1-1.2 mm thick is applied, which contains 0.2 wt. powder form. On a short part of the substrate between the strips with garden pitch, a layer of hygroscopic pad (6) 5 cm wide, pre-impregnated with a 0.005% solution of epin and dried, is fixed. The short part of the substrate is also covered with a protective removable film with a horizontal millimeter scale and a 1 mm grid (7).

The technical result of using the utility model is to reduce the time of fixation of the grafting site, higher survival rate of grafting due to reliable mechanical fixation and protection of the grafting site with a plaster, the use of physiologically active substances for plants and a fungicide.

An example of the implementation of the utility model.

To apply the patch, the scion and rootstock cuttings are preliminarily harvested, cut and prepared for grafting, the cutting and rootstock diameters are measured, which, when using the copulation grafting method, must match, and the cutting circumference is determined. Using the scale and grid on the protective film, cut off a short part of the patch, leaving a part corresponding to the circumference of the handle. If the diameter of the handle is 0.7 cm, leave 2.2 cm, if the diameter is 1 cm, leave about 3.14 cm, if the diameter of the handle is 1.5 cm, leave 4.7 cm, if the diameter of the handle is 2 cm, the short part of the patch is not cut off. Grafting is carried out by copulating the scion to the rootstock. The protective film is removed from the short part of the patch and the patch is wrapped around the place so that the middle of the pad 5 cm wide, impregnated with a 0.005% solution of epin, physiologically active for plants, is above the junction of the scion with the rootstock. The edges of the patch with a layer of garden var with a content of 0.2 wt.% fungicide fundazola tightly crimped. The protective film is removed from the sticky layer of the long part of the patch and the grafting site is wrapped over the short part of the patch with the remaining part of the patch in at least 2 layers. With a cutting diameter of 0.7-1 cm, the long part with a sticky layer can be cut off by 30-50%. The presence of several layers of the patch provides reliable mechanical fixation and protection of the grafting site. A layer of garden pitch with the addition of a fungicide protects the grafting site from infection and foreign matter. A physiologically active substance for plants stimulates the formation of callus, healing and fusion of the grafting site. After the graft and rootstock grow together, the patch is removed.
