Abstract

The invention relates to agriculture, namely, fruit production. The purpose of the invention is to reduce crop losses by extending the ripening period of the fruit and lengthening the timing of the consumption of fresh produce. The method consists in carrying out a double grafting on the stock, and first grafting the variety from which the upper skeletal branch and the central conductor are formed to the variety from the cutting of which later forms the lower crown and stem (intermediate). The upper graft is a two-glaze cutting with a diameter close to the diameter of the upper end of the cutting used as an intermediate. The variety used as an intermediate is a cutting length equal to the height of the future trunk plus the length of the cutting with two buds necessary for laying the two lower skeletal branches. The diameter of the cutting at the bottom should be close to the diameter of the stem at the base. The difference in maturity of grafted varieties is 8-12 days. Such a difference in fruit ripening will allow to increase the term of fruit consumption from one tree by 12-15 days and provide a guaranteed fruit yield in case of danger of frost during flowering and tying.

Description

The invention relates to agriculture, namely to fruit growing, and can be used in amateur gardening.

The purpose of the invention is to reduce crop losses by extending the period of fruit harvesting and lengthening the timing of consumption of fresh produce.

Example. Experimental verification of the method was carried out in 1987 on April 16, shortened cuttings were prepared for M 4 blonds with a trunk diameter at a height of 10 cm 12–15 mm and cuttings of two summer varieties Blonka Superprekos and Melba with a difference in maturity of 8–12 years. The cuttings of the superprekos variety were harvested with a length of 80-90 cm with a diameter in the lower part of 12-15 mm. This variety was used as an intermediate variety and a stem and two lower skeletal branches were formed from it. Melb cuttings were harvested 40–60 cm long and 8–10 mm in diameter at the base. From these long cuttings dvuhglazkovye cuttings are cut, of which subsequently form the upper skeletal branch of the first Rus and the center conductor. The cuttings of the Superprekos variety were cut to a length of 70-75 cm and connected to the two-glazed cuttings of the Melb variety by the method of improved coning. The vaccination site was tied with plastic wrap. Then, using the second graft, the resulting combination of the two varieties was grafted (using the improved copulation method) on the rooted rootstock M4. The graft site was tied with a film. The entire grafted plant except for the stock was covered with paraffin and planted on the day of vaccination.

So that the bottom inoculation is located at ground level. To prevent displacement of tissues at the junction of the components of the grafting under the influence of wind, the grafted plant was tied up to a stake, after spreading a mound of earth to a height of 14-16 cm.

After germination, the buds on the cuttings of the Superprekos variety were removed by scrubbing, with the exception of the two upper ones.

The method provides for the production of seedlings in one year at the minimum cost of their production.

Invention Formula The method of growing fruit seedlings, including the double grafting of cultivated varieties in the seed pods, characterized in that, in order to reduce the plant. This vaccination sequence is due to the fact that the upper variety is grafted with a double-eyed cutting handle, which yields a crop by increasing the fruit ripening period and extending the consumption of fresh produce, double grafting is carried out by grafting 10-15 times lighter than 15 cuttings on the cutting intermediate varieties of length equal to the length of the future shtamba and the zone of the skeletal branches of the first rusa of the crown, and the subsequent grafting of the varietal combination obtained on the stock, and varieties with a difference in ripeness of 8-12 days are used as grafted varieties. grafting, and therefore, when performing the second grafting under the action of its weight does not cause displacement of the cambial layers of the grafting components. In the reverse sequence of vaccination, the cambial layers may shift under the weight of the rootstock. yield losses due to the prolongation of the ripening period of the fruit and the prolongation of the consumption of fresh produce, a double graft is carried out by grafting a two-eye cutting on the cuttings of the intermediate varieties of length equal to the length of the future shtamba and the zone of the skeletal branches of the first rusa of the crown, and the subsequent grafting of the varietal combination obtained on the stock, and varieties with a difference in ripeness of 8-12 days are used as grafted varieties.
