Abstract

Use: in viticulture, in the nursery. Summary of the Invention: As a stock for cultivated varieties, phyllocero-resistant varieties are used, yielding the year of grapes. 1 tab.

Description

The invention relates to agriculture, namely to viticulture, and, in particular, is used in nursery.

The purpose of the invention is to reduce costs and increase the yields by increasing the affinity of grafted components, the resistance of grafted plants to chlorine resistance and their durability.

To accomplish this goal, it is proposed to use phylloxero-resistant grape varieties that produce grapes of the year of the grapes and carrying blood of the v.vinifera species (for example, Anapa resistant, phylloxero-resistant Jemete, etc.) as rootstocks of v.vinifera varieties. In this case, the vine used as a stock is a by-product.

New in the proposed method is the following: it is not necessary to specially lay the mother plants of the rootstock vines, which yield only the vine in the form of vines (cuttings). In connection with this, the use of additional land areas is not required, and the material and labor costs for laying and caring for such mother groves of the subsoil that are excluded are excluded.

much higher than when using the proposed technical solution.

Essential in the new method is that the proposed varieties for use as rootstocks, due to the content of v.vinifera species in them, have a short growing season (ripen well), high resistance to chlorine resistance and rhizogenesis, good affinity with grafted varieties v.vinifera. The above qualities of the proposed varieties contribute to an increase in the yield of seedlings (or grafted plants) per unit area, the possibility of growing grafted plants on carbonate soils and their greater durability.

The invention is illustrated by the following example. Experimental verification of the experiment was carried out in 1985 by OPH Anapa on the Riesling Rhine Grape variety, grafted on rootstocks: Berlandierich Riparia Kober 5BB (prototype, hybrid of American species): Anapa steady, phylloxero-resistant Dzhemete; each variant included 300 vaccinations. Vaccinations were carried out on the MPVJ vaccination machine.

7A. Care of vaccinations and seedlings carried out according to known technology.

In the fall of 1985, the seedlings were planted in a permanent place, and the planting pattern was 4.0x2.0 mm, 100 pieces in each version. Soil - carbonate black soil with a content of mobile lime 22.5%. Further care of the plantations was carried out according to the generally accepted technology. In 1989, an account was taken of the chilling and fallen bushes, according to the graft, and the magnitude of the grape yield was determined. All data are shown in the table.

An increase in the yield of first-grade inoculations was noted on average by 6.5% of standard seedlings - by 11.7%, an increase in the volume of the root system - by 8 cm, an improvement in affinity (compliance with the roots) - by 39.0%, a decrease in the number of bushes

at the expense of affinity - by 6% and chlorinating bushes - by 15%.

The increase in yield on grafted fruitful vineyards - by 16.2 q / ha. In addition, from 1 ha of queen-sized recommended rootstocks, an additional yield of grapes was obtained on average 78 c / ha.
