Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, namely to viticulture. The method includes preparing sticks of parent stock and scions, and their calibration. Eyes are removed on the parent stock. The cut on the basal part of the sticks of parent stock is refreshed. Scion is cut into one-eyed sticks. Sticks of scion and stock are soaked in water. Sticks are treated in a solution of fungicide. At the scion and the rootstock sections are made. Imparted components are connected. Place of spiking is treated with paraffin, stratification and sorting are carried out, as well as the second waxing and hardening. The grafts are planted into the nursery garden. At that, after making the cut on the rootstock, before joining imparted components, the apical portion of the stock is dipped for 1-2 seconds into the solution of a symbiont with the concentration of 0.001-0.003%.

EFFECT: invention enables to increase the yield and quality of grafted seedlings of grapes.

Description

The invention relates to agriculture, in particular to grape nursery.

A known method of grafting the grapes (A.S. No. 1505475 of 09/07/89, IPC A01G 17/00), which consists in cutting rootstock, scion and a pin of porous material, soaking them in a growth stimulator before connecting to the vaccine, use 0 as a stimulator , 02% and 0.2% aqueous heteroauxin solution. The disadvantage is that for complete saturation of the cuttings in a 0.02% aqueous solution of heteroauxin, the grafted cuttings are soaked for 1 day, and the stock ones for 4 days. In parallel, the pins are soaked for 6 hours in a 0.2% solution of heteroauxin. The implementation of these works requires additional costs for the purchase of the drug and labor costs associated with an increase in the time for soaking cuttings, an increase in the duration of work.

A known method of growing grafted grape seedlings ("Production Technology of grafted grape planting material" Auth. Maltabar AM, MCX USSR, Krasnodar, 1983, pp. 3-50), including the harvesting of cuttings of stock and scion, removal of eyes for stock, refreshment of sections on the basal part of the rootstock cuttings, cutting the scion into one-eyed cuttings, locking the scion and rootstock cuttings in water, impregnating samples, etching the cuttings in a fungicide solution, machine grafting, waxing of the adhesion site, stratification, sorting, and growing e vaccinations of the second grade, hardening, landing in the school.

The disadvantage of this method is that for the complete soaking of rootstock cuttings in a 0.005% solution of heteroauxin for two days, additional funds are required for its acquisition, the cost of paying for the work related to locking the handle before grafting, additional time for locking, low quality vaccinations.

The objective of the invention is to increase the yield and quality of grafted grape seedlings, due to the fact that in the method of growing grafted grape seedlings, which includes harvesting rootstock and scion grafts, calibrating the graft and rootstock, removing eyes on the rootstock, refreshing slices on the basal part of the rootstock graft, cutting the graft one-eye cuttings, locking of grafts of graft and rootstock in water, pickling grafts in a solution of fungicide, making cuts for rootstock and graft, joining grafted components, waxing of the spike and, stratification, sorting, second waxing, quenching, landing in the school, after making a slice on the stock, before connecting the grafted components, the apical part of the stock is immersed for 1-2 s in a symbiont solution at a concentration of 0.001-0.003%.

New in the proposed method is the use of a plant growth stimulator (symbiont) in viticulture, in particular in nursery, for the regeneration of growth processes, which contributes to better intergrowth of grafted components and the release of quality products.

The following tables are presented in the attached tables.

Table 1 - Effect of treatment of a plant growth stimulator on the qualitative characteristics and yield of grafted seedlings.

Table 2 - the effect of the concentration of the symbiont growth stimulator solution on biometric indicators and the yield of grafted seedlings.

Table 3 - qualitative characteristics and the yield of planting material as a result of treatment with a solution of the Symbiont preparation, depending on the exposure of the treatment.

The proposed method is as follows. In autumn, rootstock and scion grafts are harvested, transported to the basement for storage, with preliminary soaking, stored at 0- + 4 ° С, in March they are transported to the inoculation workshop, the eyes are removed to the rootstock, the basal part of the stem is refreshed under the eye and the rootstock is cut to length 52-55 cm, calibrate, cut one-eyed scion cuttings so that a piece of vine 1.0-1.5 cm long remains under the eye under the eye 4-5 cm, calibrate, soak (stock for 2 days, graft 12 hours), disinfect in a 0.5% solution of chinosol in for three hours, install the rootstock cuttings for 5-7 days in the stratification chamber for fitting, make a cut on the rootstock, immerse the apical part of the rootstock in a symbiont solution at a concentration of 0.001-0.003% for 1-2 s before connecting the components. To protect the joint from drying out and to delay the opening of the eyes, the grafted cuttings are dipped 1/3 of the length into the molten paraffin at a temperature of 70-75 ° C.

The proposed method for growing grafted grape seedlings using a symbiont growth regulator in worked out concentrations and time exposure allows activating the regeneration processes of callus and root formation of grafts during the stratification period, increasing the yield and improving the quality of grafted grape seedlings with cost savings.
